Description of problem: I would like to link my program with both libfftw3 and libfftw3_mpi and preferably I would like to use the pkg-config for autodetection. However at the moment it is not possible to detect both with pkgconfig, since the .pc files have both identical names. IMO the libfftw3_mpi should have come with a fftw3_mpi.pc instead of fftw3.pc file and pkg-config --libs fftw3_mpi should result in the appropriate -L/usr/lib64/openmpi/lib -lfftw3_mpi Version-Release number of selected component (if applicable): 3.3.5 How reproducible: always Steps to Reproduce: 1. install fftw-devel fftw-openmpi-devel 2. module load openmpi 3. pkg-config --libs fftw3_mpi fftw3 Actual results: Package fftw3_mpi was not found in the pkg-config search path. Perhaps you should add the directory containing `fftw3_mpi.pc' to the PKG_CONFIG_PATH environment variable Package 'fftw3_mpi', required by 'virtual:world', not found the call to pkg-config --libs fftw3 produces -L/usr/lib64/openmpi/lib -lfftw3 Expected results: I would expect the call to pkg-config --libs fftw3_mpi fftw3 to actually produce the following output: -L/usr/lib64/openmpi/lib -fftw3_mpi -lfftw3 Additional info:
I found an upstream bug, discussing similar problematic: https://github.com/FFTW/fftw3/issues/57 So dunno if this should or even can be fixed in the Fedora side (rpm spec file) or upstream? I might have time to try prepare some patches, but ATM I'm not sure what the proper solution should be.
This message is a reminder that Fedora 27 is nearing its end of life. On 2018-Nov-30 Fedora will stop maintaining and issuing updates for Fedora 27. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '27'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 27 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 27 changed to end-of-life (EOL) status on 2018-11-30. Fedora 27 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
