| Summary | 0009195: Find module for linking mixed Fortran/C code | ||||||||
| Description | When linking a Fortran library from C/C++ code, it is necessary to link the Fortran run-time libraries. Attached is a find module that attempts to do this in a portable way by compiling a simple test verbosely and scraping the output for -L and -l flags. The module has been tested on the following OS/Compiler combinations: - Linux/GNU - Linux/Intel - Linux/PGI - AIX/VisualAge | ||||||||

I've implemented automatic detection of implicit link libraries and search directories for C, C++, and Fortran compilers. There is a new undocumented, internal-only module which does the parsing: Modules/CMakeParseImplicitLinkInfo.cmake The results are stored in variables CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES but they are not meant for user consumption. A future commit will make automatic use of them for mixed-language link line computation. I've added a test file: Tests/CMakeTests/ImplicitLinkInfoTest.cmake.in which hard-codes a bunch of examples from several platforms and tests that the parser works as expected. I've tested this with GNU, MIPSpro, HP, VisualAge, SunPro. |

Detection takes place during the "Detecting <lang> compiler ABI info" step. In order to enable this for a new compiler, make sure that CMAKE_<LANG>_COMPILER_ID is computed correctly. Then add a module Modules/Compiler/<id>-<lang>.cmake containing a line like SET(CMAKE_<lang>_VERBOSE_FLAG "-v") The language <lang> can be one of "C", "CXX", or "Fortran". The ABI detection code passes this flag to its test project and parses the compiler output to extract the link line. |

Currently I do not have access to Intel or PGI compilers. Can you please test CVS HEAD CMake on these compilers? |

I've committed support for Intel and PGI too. CMake now automatically handles fortran libraries, so there is no need for users to find them. |
