[issue36843] AIX build fails with failure to get random numbers
Robert Boehne added the comment: I wonder if there's anyone with AIX 7 who can attempt to reproduce this. We have another AIX machine, but it is down for the moment. I would like to eliminate a problem on this machine as the cause. -- ___ Python tracker <https://bugs.python.org/issue36843> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Robert Boehne added the comment:
The call to open("/dev/urandom", flags) is returning -1, and errno is set to
22, EINVAL - Invalid argument. could the flags be set incorrectly?

[issue30819] Linking with 'ld -b' fails with 64-bit using Itanium HP compiler
New submission from Robert Boehne: Setting compiler flags to +DD64 produces 64-bit objects, but the linker does not understand this flag, so either you'll see an ld failure to recognize +DD64 at link time, or you'll see a failure later mixing 32 and 64-bit objects. I also modified the C++ variable because that's obviously needed as well. There was an issue with configure - after modifying one and adding another line in configure.ac, autoconf 2.69 removed all instances of "runstatedir" in the generated configure script, so I made my intended change to configure in an editor as well. -- title: Linking with 'ld -b' fails with 64-bit using HP compiler -> Linking with 'ld -b' fails with 64-bit using Itanium HP compiler ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30819> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue30183] [HPUX] compilation error in pytime.c with cc compiler
Robert Boehne added the comment: I am having trouble getting things build still. The problem is that the build is using a naked "ld" to link, and it is picking 32-bit mode by default in my 64-bit acc build. (Itanium) IMO the problem is configure.ac:2467 which should look more like the gcc section. I can produce a patch, and perhaps you can walk me though the submission process. -- ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30183> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
