I'm working on continuing to port perl5 to z/OS. One test that is
failing is beyond my knowledge level. The Dynaloader module has a
function dl_findfile() which looks for libraries in the path. It is
expecting to find libc at least, but is finding nothing.
This test does not work on several platforms, even some Unix-like ones,
and my guess is it doesn't work on z/OS either. But I am hoping someone
can give me more information.
One of the comments in the perl source says:
# On OS/390, libc.a doesn't really hold anything at all,
And that makes me think that looking for it (and perhaps any Unix-y
library) is futile.
Verify that accuracy of that comment. Use nm to dump all the c symbols
in libc.a. Does libc.a look like libc or not?
Config.pm and Configure have a "libc" var that is set through some logic
in Configure.
Porting/Glossary says
----------------------------------------------------------
libc (libc.U):
This variable contains the location of the C library.
----------------------------------------------------------
I would guess one purpose of that config var is automatically look for c
symbols with nm if you aren't doing test compiles. I'll point out
t/porting/libperl.t exists.
