| 5 | # AIX 4.1 hints thanks to Christopher Chan-Nui <channui@austin.ibm.com>. |
| 6 | # AIX 4.1 pthreading by Christopher Chan-Nui <channui@austin.ibm.com> and |
| 7 | # Jarkko Hietaniemi <jhi@iki.fi>. |
| 8 | # AIX 4.3.x LP64 build by Steven Hirsch <hirschs@btv.ibm.com> |
| 9 | # Merged on Mon Feb 6 10:22:35 EST 1995 by |
| 10 | # Andy Dougherty <doughera@lafayette.edu> |
| 11 | |
| 12 | # Contact dfavor@corridor.com for any of the following: |
| 13 | # |
| 14 | # - AIX 43x and above support |
| 15 | # - gcc + threads support |
| 16 | # - socks support |
| 17 | # |
| 18 | # Apr 99 changes: |
| 19 | # |
| 20 | # - use nm in AIX 43x and above |
| 21 | # - gcc + threads now builds |
| 22 | # [(added support for socks) Jul 99 SOCKS support rewritten] |
| 23 | # |
| 24 | # Notes: |
| 25 | # |
| 26 | # - shared libperl support is tricky. if ever libperl.a ends up |
| 27 | # in /usr/local/lib/* it can override any subsequent builds of |
| 28 | # that same perl release. to make sure you know where the shared |
| 29 | # libperl.a is coming from do a 'dump -Hv perl' and check all the |
| 30 | # library search paths in the loader header. |
| 31 | # |
| 32 | # it would be nice to warn the user if a libperl.a exists that is |
| 33 | # going to override the current build, but that would be complex. |
| 34 | # |
| 35 | # better yet, a solid fix for this situation should be developed. |
