Hi list, we're having a weird problem here. We want to compile a dynamic library for an image processing program (IDL) which is written in C++. There is a makefile that uses libtool to compile with proper switches: libtool --mode=compile --tag=CXX $(CXX) $(CFLAGS) -o <name>.lo -c <name>.cpp libtool --mode=link --tag=CXX $(CXX) -o libmomfbd.la <names>.lo -rpath $(DLM_PATH) Now this works on a Slackware computer, it creates the dynamic library as .libs/libmomfbd.so.0.0.0 On OpenSuse it doesn't :-(( Some observations: I can replace --tag=CXX with --tag=CC. Then it actually compiles, but the library misses symbols and doesn't load. Compiling with tag CXX does not add the flags -fPIC -DPIC to the compiler options. (the Slackware libtool, which is 2.2.6b compared to 2.2.6 in OS, does add those.) So to get a library, I have to - compile with --tag=CXX - manually add the -fPIC -DPIC flags - use the informational output from 'libtool --mode=link --tag=CC ...' (which will call gcc), replace gcc with g++ and link by hand This is ugly, and cannot be intended. But as I'm no programmer, I might have done things wrong. So my question is: Is something wrong in this setup (which works on another machine), or is libtool with g++ broken in OS 11.2 Cheers, Pit PS: Update: I just saw that OS 11.3 uses libtool 2.2.6b, so I installed that (plus libltdl7) for a test. Same result - no lib, and also the PIC flags are still not there. So libtool in OS is different from the same version in Slackware? -- Dr. Peter "Pit" Suetterlin http://www.astro.su.se/~pit Institute for Solar Physics Tel.: +34 922 405 590 (Spain) P.Suetterlin@royac.iac.es +46 8 5537 8507 (Sweden) Peter.Suetterlin@astro.su.se -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
