10 | # Contact dfavor@corridor.com for any of the following: | |
11 | # | |
12 | # - AIX 43x and above support | |
13 | # - gcc + threads support | |
14 | # - socks support | |
15 | # | |
16 | # Apr 99 changes: | |
17 | # | |
18 | # - use nm in AIX 43x and above | |
19 | # - gcc + threads now builds | |
29209bc5 | 20 | # [(added support for socks) Jul 99 SOCKS support rewritten] |

22 | # Notes: | |
23 | # | |
24 | # - shared libperl support is tricky. if ever libperl.a ends up | |
25 | # in /usr/local/lib/* it can override any subsequent builds of | |
26 | # that same perl release. to make sure you know where the shared | |
27 | # libperl.a is coming from do a 'dump -Hv perl' and check all the | |
28 | # library search paths in the loader header. | |
29 | # | |
30 | # it would be nice to warn the user if a libperl.a exists that is | |
31 | # going to override the current build, but that would be complex. | |
32 | # | |
33 | # better yet, a solid fix for this situation should be developed. | |
