387 | Here are some notes kindly contributed by Dean Roehrich. |
388 | |
389 | ----- |
390 | Generic notes about building Perl5 on Solaris: |
391 | - Use /usr/ccs/bin/make. |
392 | - If you use GNU make, remove its setgid bit. |
393 | - Remove all instances of *ucb* from your path. |
394 | - Make sure libucb is not in /usr/lib (it should be in /usr/ucblib). |
395 | - Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc. |
396 | - Do not use /usr/ucb/cc. |
397 | - Do not change Configure's default answers, except for the path names. |
398 | - Do not use -lmalloc. |
399 | - Do not build on SunOS 4 and expect it to work properly on SunOS 5. |
400 | - /dev/fd must be mounted if you want set-uid scripts to work. |

403 | Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note |
404 | the themes: |
405 | - run fixincludes |
406 | - run fixincludes correctly |
407 | - don't use GNU as or GNU ld |
408 | |
409 | Question 5.7 covers the __builtin_va_alist problem people are always seeing. |
410 | Question 6.1.3 covers the GNU as and GNU ld issues which are always biting |
411 | people. |
412 | Question 6.9 is for those who are still trying to compile Perl4. |

418 | Perl5 comes with a script in the top-level directory called "myconfig" which |
419 | will print a summary of the configuration in your config.sh. My summary for |
420 | Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the |
421 | results are identical. This configuration was generated with Configure's -d |
422 | option (take all defaults, don't bother prompting me). All tests pass for |
423 | Perl5.001, patch.1m. |

457 | |
458 | 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined? |
459 | |
460 | You're using gcc without properly installing the gcc fixed |
461 | include files. Or you ran fixincludes after installing gcc |
462 | w/o moving the gcc supplied varargs.h and stdarg.h files |
463 | out of the way and moving them back again later. This often |
464 | happens when people install gcc from a binary distribution. |
465 | If there's a tmp directory in gcc's include directory, fixincludes |
466 | didn't complete. You should have run "just-fixinc" instead. |
467 | |
468 | Another possible cause is using ``gcc -I/usr/include.'' |
469 | |
470 | 6.1) Where is the C compiler or where can I get one? |
471 | |
472 | [...] |
473 | |
474 | 3) Gcc. |
475 | |
476 | Gcc is available from the GNU archives in source and binary |
477 | form. Look in a directory called sparc-sun-solaris2 for |
478 | binaries. You need gcc 2.3.3 or later. You should not use |
479 | GNU as or GNU ld. Make sure you run just-fixinc if you use |
480 | a binary distribution. Better is to get a binary version and |
481 | use that to bootstrap gcc from source. |
482 | |
483 | [...] |
484 | |
485 | When you install gcc, don't make the mistake of installing |
486 | GNU binutils or GNU libc, they are not as capable as their |
487 | counterparts you get with Solaris 2.x. |
488 | |
489 | 6.9) I can't get perl 4.036 to compile or run. |
490 | |
491 | Run Configure, and use the solaris_2_0 hints, *don't* use |
492 | the solaris_2_1 hints and don't use the config.sh you may |
493 | already have. First you must make sure Configure and make |
494 | don't find /usr/ucb/cc. (It must use gcc or the native C |
495 | compiler: /opt/SUNWspro/bin/cc) |
496 | |
497 | Some questions need a special answer. |
498 | |
499 | Are your system (especially dbm) libraries compiled with gcc? [y] y |
500 | |
501 | yes: gcc 2.3.3 or later uses the standard calling |
502 | conventions, same as Sun's C. |
503 | |
504 | Any additional cc flags? [ -traditional -Dvolatile=__volatile__ |
505 | -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__ |
506 | Remove /usr/ucbinclude. |
507 | |
508 | Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm |
509 | -lucb] -lsocket -lnsl -lm |
510 | |
511 | Don't include -ldbm, -lmalloc and -lucb. |
512 | |
513 | Perl 5 compiled out of the box. |
