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. |
