Here is the current status of the hunt for the solution of this issue. In sum, the subject line should be changed to "Incomplete gfortran library link command always issued for downloaded Microsoft version of CMake but not for a bootstrapped version of CMake for MinGW/MSYS on Wine-1.5.15"
My original concerns about CMake generating bad Fortran link commands on a Windows platform involved results from two closely related software projects, ephcom and te_gen. An older version of ephcom tested well on Linux and CMake/MinGW/MSYS/Wine last year, and the latest version tests well on Linux currently. te_gen is recently resurrected (last released in 1999) Fortran software that strongly depends on ephcom and which tests well on Linux currently, but which had never been tested on Windows (CMake/MinGW/MSYS/Wine) before. Both te_gen and ephcom demonstrated that the downloaded Windows binary version of CMake-2.8.9 issued incorrect Fortran library linking commands while a version of CMake-2.8.9 that had been bootstrap-built on MinGW/MSYS/Wine issued the correct Fortran library linking commands. David and Bill are currently looking at a scripted build of ephcom to see whether they can replicate the issue on a Microsoft version of Windows. I have also given them detailed results from the good link and bad link build trees to help them figure out what is wrong with the downloaded Windows binary version of CMake-2.8.9. With the bootstrapped CMake-2.8.9, I got good test results for the current ephcom for MinGW corresponding to 4.5.2 and Wine-1.5.15. However, te_gen had run-time errors. Those were unlikely to be anything to do with the CMake bad generated link issue, but you never know, so I have been working hard on fixing those te_gen run-time issues in the last several day, and I just had complete success there. It turned out that MinGW has peculiarities in the way it handles Fortran common blocks, and the errors from that had being magnified by bugs (leading to segfaults and stackdumps) in the ephcom and te_gen error reporting system. I solved both issues by the appropriate ephcom and te_gen code changes, and the result is te_gen gave a good test result on MinGW/MSYS/Wine for the first time this morning! That result is identical to the same test run on Linux other than the expected difference in floating-point noise between the two results. So I am very happy at the moment, and I think these tests are a strong indication that there is nothing obviously wrong with the CMake-2.8.9 source code or the bootstrap build of that source code on MinGW/MSYS/Wine. However, the bad generated Fortran link issue with the downloaded binary Windows version of CMake-2.8.9 is still a concern. In an ideal world that should be producing the same good link commands for Fortran that the bootstrapped version does. If David and Bill cannot replicate the problem on Microsoft Windows or figure out what is going on from all the detailed build-tree results I gave them for the bad link and good link cases, I would be willing to do any additional experiments here they request to help see what is going wrong with the downloaded binary Windows version of CMake on Wine.
