Package: gmsh Version: 2.5.1~beta1~svn9559~dfsg-1 Severity: wishlist Tags: patch User: ubuntu-de...@lists.ubuntu.com Usertags: origin-ubuntu oneiric ubuntu-patch
the package gmsh fails to build with ld --as-needed when building with ld --as-needed the libraries must be placed after the objects needing their symbols. The package sets libraries in CMAKE_CXX_FLAGS, so they get placed in the wrong position and one gets undefined references. See the log in the ubuntu bug: https://bugs.launchpad.net/ubuntu/+source/gmsh/+bug/803181 Attached patch fixes this issue adding them to target_link_libraries(gmsh,..) and removes them from debian/rules.
