[cfarm-users] Two problems on the gcc119 machine

[Bruno Haible]

On the gcc119 (AIX 7.2) machine, there are two problems:

1) The /var partition is full:

$ df -m /tmp /var/tmp
Filesystem    MB blocks      Free %Used    Iused %Iused Mounted on
/dev/hd3       16384.00  12377.05   25%   132106     5% /tmp
/dev/hd9var     4096.00      0.00  100%     2440    33% /var

With no room on /var/tmp, 'vi' is inoperable. There is no 'vim' on this
machine. Therefore one has to use /opt/freeware/bin/emacs-nox instead.

2) A symbolic link for /usr/lib/libncurses.a exists, but linking with
this library produces a non-functional program:

$ cat conftest.c
extern int tgetent (char *, const char *);

int
main (void)
{
  return tgetent ((char *) 0, "xterm");
}

$ xlc -q64 -lncurses conftest.c

$ ./a.out 
exec(): 0509-036 Cannot load program ./a.out because of the following errors:
        0509-022 Cannot load module /opt/freeware/lib/libncurses.a(libncurses.so.6).
        0509-150   Dependent module libgcc_s.a(shr.o) could not be loaded.
        0509-022 Cannot load module libgcc_s.a(shr.o).
        0509-026 System error: A file or directory in the path name does not exist.
        0509-022 Cannot load module a.out.
        0509-150   Dependent module /opt/freeware/lib/libncurses.a(libncurses.so.6) could not be loaded.

$ ldd ./a.out
./a.out needs:
         /usr/lib/libc.a(shr_64.o)
         /usr/lib/libncurses.a(libncurses.so.6)
         /unix
         /usr/lib/libcrypt.a(shr_64.o)
Cannot find libgcc_s.a(shr.o) 

Probably another symlink /usr/lib/libgcc_s.a -> /opt/freeware/lib/libgcc_s.a
will fix this problem.
