| 340 | ----- |
| 341 | Generic notes about building Perl5 on Solaris: |
| 342 | - Use /usr/ccs/bin/make. |
| 343 | - If you use GNU make, remove its setgid bit. |
| 344 | - Remove all instances of *ucb* from your path. |
| 345 | - Make sure libucb is not in /usr/lib (it should be in /usr/ucblib). |
| 346 | - Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc. |
| 347 | - Do not use /usr/ucb/cc. |
| 348 | - Do not change Configure's default answers, except for the path names. |
| 349 | - Do not use -lmalloc. |
| 350 | - Do not build on SunOS 4 and expect it to work properly on SunOS 5. |
| 351 | - /dev/fd must be mounted if you want set-uid scripts to work. |
| 352 | |
| 353 | |
| 354 | Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note |
| 355 | the themes: |
| 356 | - run fixincludes |
| 357 | - run fixincludes correctly |
| 358 | - don't use GNU as or GNU ld |
| 359 | |
| 360 | Question 5.7 covers the __builtin_va_alist problem people are always seeing. |
| 361 | Question 6.1.3 covers the GNU as and GNU ld issues which are always biting |
| 362 | people. |
| 363 | Question 6.9 is for those who are still trying to compile Perl4. |
| 364 | |
| 365 | The latest Solaris 2 FAQ can be found in the following locations: |
| 366 | rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin |
| 367 | ftp.fwi.uva.nl:/pub/solaris |
| 368 | |
| 369 | Perl5 comes with a script in the top-level directory called "myconfig" which |
| 370 | will print a summary of the configuration in your config.sh. My summary for |
| 371 | Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the |
| 372 | results are identical. This configuration was generated with Configure's -d |
| 373 | option (take all defaults, don't bother prompting me). All tests pass for |
| 374 | Perl5.001, patch.1m. |

| 405 | From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer) |
| 406 | Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48 |
| 407 | Date: 25 Jul 1995 12:20:18 GMT |
| 408 | |
| 409 | 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined? |
| 410 | |
| 411 | You're using gcc without properly installing the gcc fixed |
| 412 | include files. Or you ran fixincludes after installing gcc |
| 413 | w/o moving the gcc supplied varargs.h and stdarg.h files |
| 414 | out of the way and moving them back again later. This often |
| 415 | happens when people install gcc from a binary distribution. |
| 416 | If there's a tmp directory in gcc's include directory, fixincludes |
| 417 | didn't complete. You should have run "just-fixinc" instead. |
| 418 | |
| 419 | Another possible cause is using ``gcc -I/usr/include.'' |
| 420 | |
| 421 | 6.1) Where is the C compiler or where can I get one? |
| 422 | |
| 423 | [...] |
| 424 | |
| 425 | 3) Gcc. |
| 426 | |
| 427 | Gcc is available from the GNU archives in source and binary |
| 428 | form. Look in a directory called sparc-sun-solaris2 for |
| 429 | binaries. You need gcc 2.3.3 or later. You should not use |
| 430 | GNU as or GNU ld. Make sure you run just-fixinc if you use |
| 431 | a binary distribution. Better is to get a binary version and |
| 432 | use that to bootstrap gcc from source. |
| 433 | |
| 434 | [...] |
| 435 | |
| 436 | When you install gcc, don't make the mistake of installing |
| 437 | GNU binutils or GNU libc, they are not as capable as their |
| 438 | counterparts you get with Solaris 2.x. |
| 439 | |
| 440 | 6.9) I can't get perl 4.036 to compile or run. |
| 441 | |
| 442 | Run Configure, and use the solaris_2_0 hints, *don't* use |
| 443 | the solaris_2_1 hints and don't use the config.sh you may |
| 444 | already have. First you must make sure Configure and make |
| 445 | don't find /usr/ucb/cc. (It must use gcc or the native C |
| 446 | compiler: /opt/SUNWspro/bin/cc) |
| 447 | |
| 448 | Some questions need a special answer. |
| 449 | |
| 450 | Are your system (especially dbm) libraries compiled with gcc? [y] y |
| 451 | |
| 452 | yes: gcc 2.3.3 or later uses the standard calling |
| 453 | conventions, same as Sun's C. |
| 454 | |
