Running a stable x86 system with a few packages testing-enabled (~x86), including xfoil. When xfoil was pulled in today, it fails to compile and generates the following output: >>> Emerging (1 of 1) sci-physics/xfoil-6.97 to / * dataflow.pdf RMD160 SHA1 SHA256 size ;-) ...

Indeed, the f77 command is not found, as the only fortran compiler I currently have on the system is gfortran and it apparently doesn't install anything named f77, symlink or otherwise. I tried re-emerging gcc (after verifying the fortran use flag is enabled) and still no f77. It appears that even though the ebuild states that gfortran is sufficient, this is not the case. Adding an f77 symlink to gfortran generates a 'missing g77' from gcc-config and the build still fails. I'll try rebuilding with ifc and report back, but it appears that gfortran at least is not sufficient.

Well, I tried installing ifc (the binary turns out to be ifort not ifc btw). Then tried "FC="ifort" emerge -uDv xfoil". Nope. It still compiles plotlib with gfortran, then dies when linking because it can't find the gfortran library. If I go to the work directory, I can't compile orrs with 'FC="gfortran" make' as their are unknown command line options. I can get orrs to compile with 'FC="ifort" make'. Trying to compile plotlib with 'FC="ifort" make' doesn't work, as the Makefile includes make.config which has uncommented both Linux and SGI sections, and FC="gfortran" ends up being set no matter what. Commenting out the SGI section allows plotlib to build with ifort. When I then go into xfoil/bin and try 'FC="ifort" make' the build fails with: ld: ../plotlib/libPltDP.a: No such file: No such file or directory That is because the Makefile in xfoil/bin has both the single precision and double precision options commented, and the double precision option is the winner. Unfortunately, plotlib compiles the single-precision version of the library. Commenting out the double-precision section of the xfoil/bin/Makefile allows 'FC="ifort" make' to complete without error. There seem to be two problems here: 1) Systems with only gfortran won't compile due to some command line option issue in orrs. I haven't investigated this any deeper. 2) The ebuild script doesn't set up the makefiles properly no matter what compiler is used. Plotlib will always build with gfortran and single-precision, and xfoil will try to link to the double-precision plotlib. IMO the best option here is to modify the upstream makefiles and have patch files accompany the ebuild. It's late. I'll look into this more tomorrow.
It should be fixed in cvs. Please re-emerge after a sync. If it persists, re-open this bug. Thanks.
