Perhaps cf77 is responding to -rdynamic and adding -lrt. The -rdynamic flag is known to work with GNU compilers on Linux: http://www.cmake.org/gitweb?p=cmake.git;a=blob;f=Modules/Platform/Linux-GNU.cmake;hb=v3.3.0-rc2#l21 That setting may be getting re-used because we don't distinguish cf77 from GNU f77 currently. For the Intel Fortran compiler we turn off use of -rdynamic here: http://www.cmake.org/gitweb?p=cmake.git;a=blob;f=Modules/Platform/Linux-Intel-Fortran.cmake;hb=v3.3.0-rc2#l4 Something similar may be needed for this compiler. Does it define a preprocessor macro to identify itself?
