when I execute makepkg, error occures. the error meassage is ---------------------------------------------------------------------------- checking whether Fortran 77 and C objects are compatible... no checking for file... file configure: error: **** Incompatible Fortran and C Object File Types! **** F77 Object File Type produced by "ifort " is : : ELF 64-bit LSB relocatable, x86-64, version 1 (GNU/Linux), not stripped. C Object File Type produced by "gcc -march=x86-64 -mtune=generic -O2 -pipe -O2" is : : ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped. ==> ERROR: A failure occurred in build(). Aborting... -------------------------------------------------------------------------------------- But just excuting "./configure" , nothing happens..everything is fine..then make as well. -------------------------------------------------------------------------------- checking whether Fortran 77 and C objects are compatible... yes checking for Fortran 77 name mangling... lower underscore --------------------------------------------------------------------------------- the diffence is "checking whether Fortran 77 and C objects are compatible..." "yes or no.."

Installing to /usr would make mpich2 conflict with openmpi which would be very bad because many users including myself use both. I removed RPATH, there are still warnings about hwloc which is a (tiny) bundled dependency, but mpich2 does not currently offer a way to use the system hwloc. Note that hwloc has an optional dependency on cairo, but mpich2 does not require that functionality. Finally, namcap says that gcc-fortran is not a real dependency, but it really is required since far too many MPI users need the fortran wrappers to function correctly.

Hi, thanks for the package! Some suggestions, after running the pkg through namcap, I got the following: http://pastie.org/private/97v2wtkz0dtaioudubwcva Can you consider installing to /usr instead of /opt? Also for the rpath warnings, there could be a disable-rpath option in the configure somewhere, otherwise it would be wise to use chrpath and remove the rpaths.

Since it's not just me hitting this, I updated the package with a patch to their configure script that fixes the problem.

"edit PKGBUILD so that MPICH2LIB_LDFLAGS and LDFLAGS are both unset" can you elaborate on how to do that?? which line to edit?

jedbrown commented on 2010-11-25 14:14 (UTC)

There is a bug upstream which causes MPICH2LIB_LDFLAGS to be included in the wrapper, as would LDFLAGS. For a reason that I don't understand, the -Wl,--as-needed from /etc/makepkg.conf which goes into the MPICH2 wrapper compilers causes libstdc++ link errors for some mixed C++/Fortran programs on my machine. The workaround (as of 1.3.1-2) is to edit PKGBUILD so that MPICH2LIB_LDFLAGS and LDFLAGS are both unset. If others are seeing this problem, I can update the PKGBUILD with this workaround, but otherwise I would rather not ignore LDFLAGS. Until they fix the problem upstream, there is no way to build the MPICH2 libraries with desired LDFLAGS without putting them into the wrappers.

Works for me, thanks. I did get this warning while building, though: WARNING: Package contains reference to $srcdir

jedbrown commented on 2010-10-29 21:07 (UTC)

Done, please report any problems.

<deleted-account> commented on 2010-10-29 20:14 (UTC)

Oh, and an /etc/ld.so.conf.d/mpich2 would be really useful, too!

<deleted-account> commented on 2010-10-29 20:13 (UTC)

Nope, no gfortran. It didn't occur to me how many people might need it, but obviously a lot of scientific code is still Fortran, and that's the segment mpich2 is aimed at!
