221 | Here are some notes kindly contributed by Dean Roehrich. |
222 | |
223 | ----- |
224 | Generic notes about building Perl5 on Solaris: |
225 | - Use /usr/ccs/bin/make. |
226 | - If you use GNU make, remove its setgid bit. |
227 | - Remove all instances of *ucb* from your path. |
228 | - Make sure libucb is not in /usr/lib (it should be in /usr/ucblib). |
229 | - Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc. |
230 | - Do not use /usr/ucb/cc. |
231 | - Do not change Configure's default answers, except for the path names. |
232 | - Do not use -lmalloc. |
233 | - Do not build on SunOS 4 and expect it to work properly on SunOS 5. |
234 | - /dev/fd must be mounted if you want set-uid scripts to work. |
235 | |
236 | |
237 | Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note |
238 | the themes: |
239 | - run fixincludes |
240 | - run fixincludes correctly |
241 | - don't use GNU as or GNU ld |
242 | |
243 | Question 5.7 covers the __builtin_va_alist problem people are always seeing. |
244 | Question 6.1.3 covers the GNU as and GNU ld issues which are always biting |
245 | people. |
246 | Question 6.9 is for those who are still trying to compile Perl4. |
247 | |
248 | The latest Solaris 2 FAQ can be found in the following locations: |
249 | rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin |
250 | ftp.fwi.uva.nl:/pub/solaris |
251 | |
252 | Perl5 comes with a script in the top-level directory called "myconfig" which |
253 | will print a summary of the configuration in your config.sh. My summary for |
254 | Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the |
255 | results are identical. This configuration was generated with Configure's -d |
256 | option (take all defaults, don't bother prompting me). All tests pass for |
257 | Perl5.001, patch.1m. |
258 | |
259 | Summary of my perl5 (patchlevel 1) configuration: |

289 | Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48 |
290 | Date: 25 Jul 1995 12:20:18 GMT |
291 | |
292 | 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined? |
293 | |
294 | You're using gcc without properly installing the gcc fixed |
295 | include files. Or you ran fixincludes after installing gcc |
296 | w/o moving the gcc supplied varargs.h and stdarg.h files |
297 | out of the way and moving them back again later. This often |
298 | happens when people install gcc from a binary distribution. |
299 | If there's a tmp directory in gcc's include directory, fixincludes |
300 | didn't complete. You should have run "just-fixinc" instead. |
301 | |
302 | Another possible cause is using ``gcc -I/usr/include.'' |
303 | |
304 | 6.1) Where is the C compiler or where can I get one? |
305 | |
306 | [...] |
307 | |
308 | 3) Gcc. |
309 | |
310 | Gcc is available from the GNU archives in source and binary |
311 | form. Look in a directory called sparc-sun-solaris2 for |
312 | binaries. You need gcc 2.3.3 or later. You should not use |
313 | GNU as or GNU ld. Make sure you run just-fixinc if you use |
314 | a binary distribution. Better is to get a binary version and |
315 | use that to bootstrap gcc from source. |
316 | |
317 | [...] |
318 | |
319 | When you install gcc, don't make the mistake of installing |
320 | GNU binutils or GNU libc, they are not as capable as their |
321 | counterparts you get with Solaris 2.x. |
322 | |
323 | 6.9) I can't get perl 4.036 to compile or run. |
324 | |
325 | Run Configure, and use the solaris_2_0 hints, *don't* use |
326 | the solaris_2_1 hints and don't use the config.sh you may |
327 | already have. First you must make sure Configure and make |
328 | don't find /usr/ucb/cc. (It must use gcc or the native C |
329 | compiler: /opt/SUNWspro/bin/cc) |
330 | |
331 | Some questions need a special answer. |
332 | |
333 | Are your system (especially dbm) libraries compiled with gcc? [y] y |
334 | |
335 | yes: gcc 2.3.3 or later uses the standard calling |
336 | conventions, same as Sun's C. |
337 | |
338 | Any additional cc flags? [ -traditional -Dvolatile=__volatile__ |
339 | -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__ |
340 | Remove /usr/ucbinclude. |
341 | |
342 | Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm |
343 | -lucb] -lsocket -lnsl -lm |
344 | |
345 | Don't include -ldbm, -lmalloc and -lucb. |
346 | |
347 | Perl 5 compiled out of the box. |
