This seems to be caused by a few libraries not being detected by the |
| 61 |
auto-configure program, it is relatively easy to fix. Edit your |
| 62 |
Makefile, |
| 63 |
note that yours may be slightly different than this one when it comes |
| 64 |
to |
| 65 |
the tcl library, but here is the way it probably is: |
| 66 |
|
| 67 |
GMAKE = ${MAKE} 'CC=gcc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl.a'\ |
| 68 |
'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS= -L/usr/local/lib |
| 69 |
-ltcl -lm'\ |
| 70 |
'TCLLIB=${TCLLIB}' 'RANLIB=:' 'STRIP=' |
| 71 |
|
| 72 |
And here is what you need to change: |
| 73 |
|
| 74 |
GMAKE = ${MAKE} 'CC=gcc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl.a'\ |
| 75 |
'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS=-lsocket -ldl -lnsl |
| 76 |
-L/usr/local/lib -ltcl -lm'\ |
| 77 |
'TCLLIB=${TCLLIB}' 'RANLIB=:' 'STRIP=' |
| 78 |
|
| 79 |
You are adding in three libraries to be linked in, socket, dl, and |
| 80 |
nsl. This |
| 81 |
will resolve the net.o errors. |
| 82 |
|
| 83 |
2. COMPILE STOPS AT THE LAST MINUTE WITH "LD FATAL SIGNAL 11"! (Linux) |
| 84 |
|
| 85 |
This seems to be caused by a non-ELF Tcl library binary, and the |
| 86 |
compiler doesn't seem to like it. The first thing you want to do is |
| 87 |
download and compile tcl yourself. And then follow this set of |
| 88 |
commands to help you reconfigure eggdrop using the newly compiled Tcl |
| 89 |
library (all of this should be done from your home directory): |
| 90 |
|
| 91 |
cd |
| 92 |
mkdir lib |
| 93 |
mkdir include |
| 94 |
find . -name libtcl* |
| 95 |
|
| 96 |
The output from the find command should give you the location of the |
| 97 |
library, take the output of that and do the next command with the |
| 98 |
output of find replacing $$find$$: |
| 99 |
|
| 100 |
mv $$find$$ lib/libtcl.a |
| 101 |
|
| 102 |
Now we continue with another find to help us locate tcl.h: |
| 103 |
|
| 104 |
find . -name tcl.h |
| 105 |
|
| 106 |
The output from the find command should give you the location of the |
| 107 |
header file, take the output of that and do the next command with the |
| 108 |
output of find replacing $$find$$: |
| 109 |
|
| 110 |
mv $$find$$ include |
| 111 |
|
| 112 |
Hopefully you know what shell you are using and can pick out which |
| 113 |
commands to use, if the first two setenv commands give command not |
| 114 |
found then use the next two, if not then don't use the next two. |
| 115 |
First set are for csh/tcsh users, following set is for bash/ksh users. |
| 116 |
|
| 117 |
csh/tcsh: |
| 118 |
setenv TCLLIB '$HOME/lib' |
| 119 |
setenv TCLINC '$HOME/include' |
| 120 |
|
| 121 |
bash/ksh: |
| 122 |
export TCLLIB='$HOME/lib' |
| 123 |
export TCLINC='$HOME/include' |
| 124 |
|
| 125 |
And then finally run configure again for eggdrop and then make, and |
| 126 |
hopefully it will work. |
| 127 |
|
| 128 |
3. LD: -ltcl7.4: EXPECTED LIBX.SO(.MAJOR.MINOR.XXX) (various) |
| 129 |
|
| 130 |
ld: -ltcl7.4: expected libx.so(.major.minor.xxx) |
| 131 |
collect2: ld returned 4 exit status |
| 132 |
*** Error code 1 |
| 133 |
make: Fatal error: Command failed for target `eggdrop' |
| 134 |
|
| 135 |
|
| 136 |
On some Unix boxes this seems to be caused by the linker, it is |
| 137 |
expecting a specific filename format and when it doesn't live up to |
| 138 |
it's expectations it usually barfs. I always see this caused by when |
| 139 |
the library for Tcl is called libtcl7.4.a or libtcl7.5.a, rename it to |
| 140 |
simply libtcl.a if you installed Tcl yourself, if you didn't and your |
| 141 |
using the Tcl that the system installed then do this: |
| 142 |
|
| 143 |
View your Makefile, look for the line (should be close to the top) |
| 144 |
that says |
| 145 |
|
| 146 |
XREQ = /usr/local/lib/libtcl7.4.a |
| 147 |
|
| 148 |
And remember that FULL pathname. Go to your home directory, and do |
| 149 |
the following: |
| 150 |
|
| 151 |
mkdir lib |
| 152 |
cd lib |
| 153 |
ln -s $$xreq$$ libtcl.a |
| 154 |
|
| 155 |
Replace $$xreq$$ with the full pathname from the XREQ line from the |
| 156 |
Makefile. |
| 157 |
|
| 158 |
And finally the next thing you want to do depending on what shell your |
| 159 |
using is: (try the first one, if it gives bad command then use the |
| 160 |
second) |
| 161 |
|
| 162 |
csh/tcsh: |
| 163 |
setenv TCLLIB '$HOME/lib' |
| 164 |
|
| 165 |
bash/ksh: |
| 166 |
export TCLLIB='$HOME/lib' |
| 167 |
|
| 168 |
Did I say finally? Heh, finally run configure and then make again. |
| 169 |
|
| 170 |
4. STRIP TERMINATED WITH SIGNAL 6 (various) |
| 171 |
|
| 172 |
collect2: strip terminated with signal 6 [IOT/Abort trap] |
| 173 |
*** Exit 1 |
| 174 |
Stop. |
| 175 |
*** Exit 1 |
| 176 |
Stop. |
| 177 |
|
| 178 |
I don't really know what the hell is causing this, but I find that if |
| 179 |
you |
| 180 |
don't strip the binary you cut out the problem (obviously), edit your |
| 181 |
Makefile and change this line from: |
| 182 |
|
| 183 |
GMAKE = ${MAKE} 'CC=gcc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl.a'\ |
| 184 |
'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS= -L/usr/local/lib |
| 185 |
-ltcl -lm' \ |
| 186 |
'TCLLIB=${TCLLIB}' 'RANLIB=ranlib' 'STRIP=-s' |
| 187 |
|
| 188 |
To this line below: (your lines may differ, but what you are doing is |
| 189 |
|
| 190 |
changing 'STRIP=-s' to 'STRIP=') |
| 191 |
|
| 192 |
GMAKE = ${MAKE} 'CC=gcc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl.a'\ |
| 193 |
'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS= -L/usr/local/lib |
| 194 |
-ltcl -lm' \ |
| 195 |
'TCLLIB=${TCLLIB}' 'RANLIB=ranlib' 'STRIP=' |
| 196 |
|
| 197 |
5. 'DIR' UNDECLARED (AND A WHOLE BUNCH OF OTHERS) (AIX 4) |
| 198 |
|
| 199 |
gcc -c -O2 -fno-strength-reduce -I.. -DHAVE_CONFIG_H filedb.c |

| 221 |

| 222 |
make: The error code from the last command is 1. |
| 223 |
|
| 224 |
This seems like one of the components of configure was broken, because |
| 225 |
what apparently happened was it didn't detect that this particular |
| 226 |
system had dirent.h and sys/dir.h, solution was to add -DHAVE_DIRENT_H |
| 227 |
-DHAVE_SYS_DIR_H to the Makefile's CFLGS line... |
| 228 |
|
| 229 |
CFLGS = -DHAVE_DIRENT_H -DHAVE_SYS_DIR_H |
| 230 |
|
| 231 |
6. 'FD_SET' UNDECLARED (AND A WHOLE BUNCH OF OTHERS) (AIX 4) |
| 232 |
|
| 233 |
gcc -c -O2 -fno-strength-reduce -I.. -DHAVE_CONFIG_H |
| 234 |
-DHAVE_DIRENT_H -DHAVE_SYS_DIR_H net.c |
| 235 |
net.c: In function `sockread': |
| 236 |
net.c:390: `fd_set' undeclared (first use this function) |
| 237 |
net.c:390: (Each undeclared identifier is reported only once |
| 238 |
net.c:390: for each function it appears in.) |
| 239 |
net.c:390: parse error before `fd' |
| 240 |
net.c:396: `fd' undeclared (first use this function) |
| 241 |
make: The error code from the last command is 1. |
| 242 |
|
| 243 |
Again, this seems that one of configure's components (sed, awk, or |
| 244 |
something along those lines) was broken, and it failed to detect that |
| 245 |
this system needed sys/select.h, solution was to add |
| 246 |
-DHAVE_SYS_SELECT_H to the Makefile's CFLGS |
| 247 |
line... |
| 248 |
|
| 249 |
CFLGS = -DHAVE_DIRENT_H -DHAVE_SYS_DIR_H -DHAVE_SYS_SELECT_H |
| 250 |
|
| 251 |
(I suppose they thought a minor error would deter anyone from |
| 252 |
continuing onward, but I am not just anyone, I am a blockhead... |
| 253 |
<grin>) |
| 254 |
|
| 255 |
7. UNRESOLVED OR UNDEFINED SYMBOLS: ldclose, ldopen, ldnshread (AIX 3) |

| 270 |
|
| 271 |
Apparently what is happening is a library called ld is required, and |
| 272 |
either configure doesn't know it is needed or it simple can't find it, |
| 273 |
or maybe this is a unique case, solution was to have ld linked in with |
| 274 |
the final binary. |
| 275 |
|
| 276 |
Edit your Makefile and find the line that looks something like this: |
| 277 |
|
| 278 |
GMAKE = ${MAKE} 'CC=cc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl7.5.a'\ |
| 279 |
'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS= |
| 280 |
-L/home2/f/foster/lib -ltcl7.5 -lm'\ |
| 281 |
'TCLLIB=${TCLLIB}' 'RANLIB=ranlib' 'STRIP=-s' |
| 282 |
|
| 283 |
And add in -lld into the XLIBS assignment, like this... |
| 284 |
|
| 285 |
GMAKE = ${MAKE} 'CC=cc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl7.5.a'\ |
| 286 |
'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS=-lld |
| 287 |
-L/home2/f/foster/lib -ltcl7.5 -lm'\ |
| 288 |
'TCLLIB=${TCLLIB}' 'RANLIB=ranlib' 'STRIP=-s' |
| 289 |
|
| 290 |
8. UNSATISFIED SYMBOLS 'shl_findsym' and 'shl_load' (HP-UX 9) |

| 303 |
|
| 304 |
I forwarded this one to Robey and he said that Tcl 7.5 the dl library, |
| 305 |
and that |
| 306 |
apparently configure couldn't detect that this was required in this |
| 307 |
case. So |
| 308 |
try this fix, and if it works, great, if not then use Tcl 7.4, I hear |
| 309 |
this |
| 310 |
works. :) |
| 311 |
|
| 312 |
GMAKE = ${MAKE} 'CC=gcc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl7.5.a'\ |
| 313 |
|
| 314 |
'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS= -L/usr/local/lib |
| 315 |
-ltcl7.5 -lm'\ |
| 316 |
'TCLLIB=${TCLLIB}' 'RANLIB=:' 'STRIP=' |
| 317 |
|
| 318 |
And here is what you need to change: |
| 319 |
|
| 320 |
GMAKE = ${MAKE} 'CC=gcc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl7.5.a'\ |
| 321 |
|
| 322 |
'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS=-ldl -L/usr/local/lib |
| 323 |
-ltcl7.5 -lm'\ |
| 324 |
'TCLLIB=${TCLLIB}' 'RANLIB=:' 'STRIP=' |
| 325 |
|
| 326 |
Basically what you are doing is adding in -ldl to the XLIBS |
| 327 |
declaration, |
| 328 |
essentially at link time you are tell it to also link in the dl |
| 329 |
library which |
| 330 |
apparently resolves this problem. |
| 331 |
|
| 332 |
9. Bot doesn't compile on Ultrix |
| 333 |
|
| 334 |
There are some known problems with make and Eggdrop on Ultrix systems. |
| 335 |
Try to use gmake instead. Additionally sh5 should be use, a simple |
| 336 |
'gmake SHELL=/bin/sh5' should be enough. |
| 337 |
|
| 338 |
10. Bot crashes at startup with msg "net.c/708" for example |
| 339 |
|
| 340 |
On some not IA32 systems the gcc options -O2 and -O3 cause that. We don't |
| 341 |
know why this happens but sometimes it helps to remove those options from |
| 342 |
the Makefile. Just give it a try. |
| 343 |
Ah well, drop us a note if you know why, so we can extend the info here. |
| 344 |
|
| 345 |
11. I get lot's of warnings |
| 346 |
|
| 347 |
Well, warnings are warning, nothing really bad. As long as the compile runs |
| 348 |
through, there is nothing to worry about. Generally we try to avoid |
| 349 |
warnings, but we do not have time to fix all of them in the code. This |
| 350 |
might change in the future, but at the moment you have to live with them. |
| 351 |
If you feel like fixing them, do so and send us a patch (as described in |
| 352 |
doc/patch-HOWTO). Thanks. |

Seems that configure had a brain fart... Would you believe this was |
| 386 |
the same system as in A.6 and A.7, heh, it was. Apparently it thought |
| 387 |
this system didn't have unistd.h, and was using it's compatible |
| 388 |
header, solution was to edit Makefile and change this line: |
| 389 |
|
| 390 |
AC_FLAGS = -DHAVE_________=1 -DSTDC_HEADERS=1 -DNO_UNION_WAIT=1 |
| 391 |
-DNEED_MATHERR=1 -Dvfork=fork |
| 392 |
|
| 393 |
to the following: |
| 394 |
|
| 395 |
AC_FLAGS = -DHAVE_UNISTD_H=1 -DSTDC_HEADERS=1 -DNO_UNION_WAIT=1 |
| 396 |
-DNEED_MATHERR=1 -Dvfork=fork |
| 397 |
|
| 398 |
2. CONFLICTING TYPES FOR 'waitpid' (Tcl 7.5/SunOS 5.4) |
| 399 |
|
| 400 |
cc -c -O -I./../generic -I. -DNO_STRERROR=1 -DNO_GETWD=1 |
| 401 |

| 406 |
./../compat/waitpid.c:69: conflicting types for `waitpid' |
| 407 |

| 408 |
make: *** [waitpid.o] Error 1 |
| 409 |
|
| 410 |
Configure apparently couldn't figure this one out, probably because |
| 411 |
the system it was configured on sucks badly. Change the following |
| 412 |
line in Makefile: |
| 413 |
|
| 414 |
COMPAT_OBJS = getcwd.o opendir.o strstr.o strtol.o tmpnam.o |
| 415 |
waitpid.o strstr.o strtoul.o strtod.o strncasecmp.o |
| 416 |
|
| 417 |
To the following |
| 418 |
|
| 419 |
COMPAT_OBJS = getcwd.o opendir.o strstr.o strtol.o tmpnam.o |
| 420 |
strstr.o strtoul.o strtod.o strncasecmp.o |
| 421 |
|
| 422 |
We are deleting the waitpid.o object file. The problem was that |
| 423 |
configure didn't detect that waitpid() wasn't necessary, so it caused |
| 424 |
a compatible waitpid() function to be compiled. |
| 425 |
|
| 426 |

Configure couldn't find or detect that nsl and socket libraries were |
| 472 |
required, so we have to force it to use them. The solution is to edit |
| 473 |
Makefile and change the following line: |
| 474 |
|
| 475 |
LIBS = -ldl |
| 476 |
|
| 477 |
To the following: |
| 478 |
|
| 479 |
LIBS = -ldl -lnsl -lsocket |
| 480 |
|
| 481 |
4. UNDEFINED SYMBOL 'getwd' IN getcwd.o (Tcl 7.5/SunOS 5.4) |
| 482 |
|
| 483 |

Configure apparently couldn't figure this one out, probably because |
| 495 |
the system it was configured on sucks badly. Change the following |
| 496 |
line in Makefile: |
| 497 |
|
| 498 |
COMPAT_OBJS = getcwd.o opendir.o strstr.o strtol.o tmpnam.o |
| 499 |
strstr.o strtoul.o strtod.o strncasecmp.o |
| 500 |
|
| 501 |
To the following |
| 502 |
|
| 503 |
COMPAT_OBJS = opendir.o strstr.o strtol.o tmpnam.o strstr.o |
| 504 |
strtoul.o strtod.o strncasecmp.o |
| 505 |
|
| 506 |
We are deleting the getcwd.o object file. The problem was that |
| 507 |
configure didn't detect that getcwd() wasn't necessary, so it caused a |
| 508 |
compatible getcwd() function to be compiled. |

5. There's no TCL installed on your shell |
| 511 |
|
| 512 |
If there's really no TCL installed on your shell, you can install it |
| 513 |
temporary in /tmp or your home. Get the newest version of TCL from |
| 514 |
ftp.eggheads.org/pub/tcl/ (anything above TCL 8.2 should be fine) and |
| 515 |
follow the installation steps in the README. After you've installed |
| 516 |
tcl, you have to make configure detect tcl. To achieve this, you have |
| 517 |
to set either environmental variables: |
| 518 |
|
| 519 |
export TCLLIB=/path/to/tcl/lib |
| 520 |
export TCLINC=/path/to/tcl/include |
| 521 |
|
| 522 |
Please note that on some unix machines export doesn't work and you |
| 523 |
have to use 'setenv' instead or to pass configure the full qualified |
| 524 |
path to tcl: |
| 525 |
|
| 526 |
./configure --with-tcllib=/path/to/libtclx.x.so |
| 527 |
--with-tclinc=/path/to/tcl.h |
| 528 |
