Hi,
thanks a lot, this helped! I've manually inserted "-lsocket -lnsu -lrt" in
the CMake generated makefile, and the compilation (and linking) was
successfull. However, manually editing the makefile is definitely not
desirable. Does anybody know how to make CMake inserting this linking
commands itself?
The same configuration (program + CMakeLists.txt) works fine under Linux.
Above linker commands are not necessary (and not generated by CMake). Does
anybody know why they are needed in the Sun environment?
Thanks,
Michael
