All,
today I came accross a somehow strange (at least for me) problem....
Usually I build my DLLs (written in C and C++) in the MVS-World of z/OS.
But now I want to build the same DLL under USS (because I can do this
all remote using SSH).
When I try to compile and link my DLL (it's just one C-Source file) in
one command, the DLL get's build, but somehow doesn't work (can't be
loaded and/or the enty-points are not found). Furthermore the DLL is
much larger as if it is build under MVS.
like this:
c89 -Wc,"MY,OPTIONS" -Wl,"MY_OTHER_OPTIONS" -o libfoo.so foo.c
If I compile the module with the "-c" switch (--> don't link) and then
link the module to a DLL in a second step, the Linker tells me that
CEESTART can't be resolved....
c89 -c -Wc,"MY,OPTIONS" foo.c
c89 -Wl,"MY_OTHER_OPTIONS" -o libfoo.so foo.o
It seems so me that (for some reason) the linker dosn't know where to
look for the LE-Runtimes - but the file
/usr/lpp/cbclib/xlc/etc/usr/lpp/cbclib/xlc/
looks ok so far....
Would be great if anyone has an idea....
Thank you,
Michael
