It turns out a simple test case for with cmake-2.8.0 does not show this issue. Furthermore, if I adjust our build system to completely drop our support for additional Fortran compilers so that we end up using the exact cmake-2.8.0 Fortran language support, then the problem disappears. In sum, for Fortran static libraries we only support cmake-2.6.x now. It's possible that later we will be able to support cmake-2.8.x with our additional Fortran compilers, but I will have to investigate that further. But there is no possibility to simultanously support our Fortran modifications (at least for static Fortran libraries) under cmake-2.6.x and cmake-2.8.x simultaneously because of incompatibilities between the two versions of Fortran support which cause weird errors like using g++ for linking. So you should avoid cmake-2.8.0 for Fortran static libraries until we change our minimum CMake version (currently 2.6.0) to 2.8.x. That change is not imminent. Alan __________________________ Alan W.
