217 | Here are some notes kindly contributed by Dean Roehrich. |
218 | |
219 | ----- |
220 | Generic notes about building Perl5 on Solaris: |
221 | - Use /usr/ccs/bin/make. |
222 | - If you use GNU make, remove its setgid bit. |
223 | - Remove all instances of *ucb* from your path. |
224 | - Make sure libucb is not in /usr/lib (it should be in /usr/ucblib). |
225 | - Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc. |
226 | - Do not use /usr/ucb/cc. |
227 | - Do not change Configure's default answers, except for the path names. |
228 | - Do not use -lmalloc. |
229 | - Do not build on SunOS 4 and expect it to work properly on SunOS 5. |
230 | - /dev/fd must be mounted if you want set-uid scripts to work. |
231 | |
232 | |
233 | Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note |
234 | the themes: |
235 | - run fixincludes |
236 | - run fixincludes correctly |
237 | - don't use GNU as or GNU ld |
238 | |
239 | Question 5.7 covers the __builtin_va_alist problem people are always seeing. |
240 | Question 6.1.3 covers the GNU as and GNU ld issues which are always biting |
241 | people. |
242 | Question 6.9 is for those who are still trying to compile Perl4. |
243 | |
244 | The latest Solaris 2 FAQ can be found in the following locations: |
245 | rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin |
246 | ftp.fwi.uva.nl:/pub/solaris |
247 | |
248 | Perl5 comes with a script in the top-level directory called "myconfig" which |
249 | will print a summary of the configuration in your config.sh. My summary for |
250 | Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the |
251 | results are identical. This configuration was generated with Configure's -d |
252 | option (take all defaults, don't bother prompting me). All tests pass for |
253 | Perl5.001, patch.1m. |
254 | |
255 | Summary of my perl5 (patchlevel 1) configuration: |

285 | Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48 |
286 | Date: 25 Jul 1995 12:20:18 GMT |
287 | |
288 | 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined? |
289 | |
290 | You're using gcc without properly installing the gcc fixed |
291 | include files. Or you ran fixincludes after installing gcc |
292 | w/o moving the gcc supplied varargs.h and stdarg.h files |
293 | out of the way and moving them back again later. This often |
294 | happens when people install gcc from a binary distribution. |
295 | If there's a tmp directory in gcc's include directory, fixincludes |
296 | didn't complete. You should have run "just-fixinc" instead. |
297 | |
298 | Another possible cause is using ``gcc -I/usr/include.'' |
299 | |
300 | 6.1) Where is the C compiler or where can I get one? |
301 | |
302 | [...] |
303 | |
304 | 3) Gcc. |
305 | |
306 | Gcc is available from the GNU archives in source and binary |
307 | form. Look in a directory called sparc-sun-solaris2 for |
308 | binaries. You need gcc 2.3.3 or later. You should not use |
309 | GNU as or GNU ld. Make sure you run just-fixinc if you use |
310 | a binary distribution. Better is to get a binary version and |
311 | use that to bootstrap gcc from source. |
312 | |
313 | [...] |
314 | |
315 | When you install gcc, don't make the mistake of installing |
316 | GNU binutils or GNU libc, they are not as capable as their |
317 | counterparts you get with Solaris 2.x. |
318 | |
319 | 6.9) I can't get perl 4.036 to compile or run. |
320 | |
321 | Run Configure, and use the solaris_2_0 hints, *don't* use |
322 | the solaris_2_1 hints and don't use the config.sh you may |
323 | already have. First you must make sure Configure and make |
324 | don't find /usr/ucb/cc. (It must use gcc or the native C |
325 | compiler: /opt/SUNWspro/bin/cc) |
326 | |
327 | Some questions need a special answer. |
328 | |
329 | Are your system (especially dbm) libraries compiled with gcc? [y] y |
330 | |
331 | yes: gcc 2.3.3 or later uses the standard calling |
332 | conventions, same as Sun's C. |
333 | |
334 | Any additional cc flags? [ -traditional -Dvolatile=__volatile__ |
335 | -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__ |
336 | Remove /usr/ucbinclude. |
337 | |
338 | Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm |
339 | -lucb] -lsocket -lnsl -lm |
340 | |
341 | Don't include -ldbm, -lmalloc and -lucb. |
342 | |
343 | Perl 5 compiled out of the box. |
