247 | Here are some notes kindly contributed by Dean Roehrich. |
248 | |
249 | ----- |
250 | Generic notes about building Perl5 on Solaris: |
251 | - Use /usr/ccs/bin/make. |
252 | - If you use GNU make, remove its setgid bit. |
253 | - Remove all instances of *ucb* from your path. |
254 | - Make sure libucb is not in /usr/lib (it should be in /usr/ucblib). |
255 | - Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc. |
256 | - Do not use /usr/ucb/cc. |
257 | - Do not change Configure's default answers, except for the path names. |
258 | - Do not use -lmalloc. |
259 | - Do not build on SunOS 4 and expect it to work properly on SunOS 5. |
260 | - /dev/fd must be mounted if you want set-uid scripts to work. |
261 | |
262 | |
263 | Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note |
264 | the themes: |
265 | - run fixincludes |
266 | - run fixincludes correctly |
267 | - don't use GNU as or GNU ld |
268 | |
269 | Question 5.7 covers the __builtin_va_alist problem people are always seeing. |
270 | Question 6.1.3 covers the GNU as and GNU ld issues which are always biting |
271 | people. |
272 | Question 6.9 is for those who are still trying to compile Perl4. |
273 | |
274 | The latest Solaris 2 FAQ can be found in the following locations: |
275 | rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin |
276 | ftp.fwi.uva.nl:/pub/solaris |
277 | |
278 | Perl5 comes with a script in the top-level directory called "myconfig" which |
279 | will print a summary of the configuration in your config.sh. My summary for |
280 | Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the |
281 | results are identical. This configuration was generated with Configure's -d |
282 | option (take all defaults, don't bother prompting me). All tests pass for |
283 | Perl5.001, patch.1m. |
284 | |
285 | Summary of my perl5 (patchlevel 1) configuration: |

314 | From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer) |
315 | Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48 |
316 | Date: 25 Jul 1995 12:20:18 GMT |
317 | |
318 | 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined? |
319 | |
320 | You're using gcc without properly installing the gcc fixed |
321 | include files. Or you ran fixincludes after installing gcc |
322 | w/o moving the gcc supplied varargs.h and stdarg.h files |
323 | out of the way and moving them back again later. This often |
324 | happens when people install gcc from a binary distribution. |
325 | If there's a tmp directory in gcc's include directory, fixincludes |
326 | didn't complete. You should have run "just-fixinc" instead. |
327 | |
328 | Another possible cause is using ``gcc -I/usr/include.'' |
329 | |
330 | 6.1) Where is the C compiler or where can I get one? |
331 | |
332 | [...] |
333 | |
334 | 3) Gcc. |
335 | |
336 | Gcc is available from the GNU archives in source and binary |
337 | form. Look in a directory called sparc-sun-solaris2 for |
338 | binaries. You need gcc 2.3.3 or later. You should not use |
339 | GNU as or GNU ld. Make sure you run just-fixinc if you use |
340 | a binary distribution. Better is to get a binary version and |
341 | use that to bootstrap gcc from source. |
342 | |
343 | [...] |
344 | |
345 | When you install gcc, don't make the mistake of installing |
346 | GNU binutils or GNU libc, they are not as capable as their |
347 | counterparts you get with Solaris 2.x. |
348 | |
349 | 6.9) I can't get perl 4.036 to compile or run. |
350 | |
351 | Run Configure, and use the solaris_2_0 hints, *don't* use |
352 | the solaris_2_1 hints and don't use the config.sh you may |
353 | already have. First you must make sure Configure and make |
354 | don't find /usr/ucb/cc. (It must use gcc or the native C |
355 | compiler: /opt/SUNWspro/bin/cc) |
356 | |
357 | Some questions need a special answer. |
358 | |
359 | Are your system (especially dbm) libraries compiled with gcc? [y] y |
360 | |
361 | yes: gcc 2.3.3 or later uses the standard calling |
362 | conventions, same as Sun's C. |
363 | |
364 | Any additional cc flags? [ -traditional -Dvolatile=__volatile__ |
365 | -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__ |
366 | Remove /usr/ucbinclude. |
367 | |
368 | Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm |
369 | -lucb] -lsocket -lnsl -lm |
370 | |
371 | Don't include -ldbm, -lmalloc and -lucb. |
372 | |
373 | Perl 5 compiled out of the box. |
