I've ran into an issue compiling openib's Dynamic SL support on a RH
6.2 based system with the Oracle Studio compilers.
Turns out if I compile btl_openib_connect_sl.c with the Oracle Studio
compilers with the "-g" option the compiler compiles some static inline
functions in ib_types.h standalone (as opposed to ignoring the functions
since they are not called in the btl_openib_connect_sl.c source). This
creates a dependency on the symbol ib_error_str in
btl_openib_connect_sl.o . Note this symbol is defined in libosmcomp.so.
My question is should btl_openib_connect_sl.c be linking to
libosmcomp.so since btl_openib_connect_sl.c is including ib_types.h or
is there an assumption being made that btl_openib_connect_sl.c is just
using macros/defines provided by the header and nothing requiring access
I ask this because I can make my original issue go away on RH 5.X
systems if I link in libosmcomp.so however, this library doesn't exist
on RH 6.2 systems without RH 5 compat headers package and doesn't have a
32 bit version on RH 6.2 systems at all. The point is if I try to fix
the libosmcomp.so dependency by doing an AC_CHECK_LIB that RH 6.X system
will actually stop configuring in Dynamic SL.
