That's do to this rule: https://github.com/FFTW/fftw3/blob/d59abdaaeb31af8a7d7f2d2ffa92931efd344e6c/m4/acx_pthread.m4#L222-L227 … this may be obsolete, as at the time it was written we were testing on ancient AIX versions.
A workaround is to configure with PTHREAD_CC=$CC
A workaround is to configure with
PTHREAD_CC=$CC
That did the trick, maybe this rule should be somewhat relaxed.
Hello,
I'm noticing something odd when trying to compile FFTW 3.3.8 on OpenPOWER using PGI 18.5.
If I use the
--enable-threads
option when calling theconfigure
script, the PGI compiler seems to be replaced by XLC.Here are the relevant environment variables that are set before calling the
configure
script:Here is the configuration log for
./configure
: config.log, note thatFFTW_CC
is defined as"/opt/pgi/linuxpower/18.5/bin/pgcc -Masmkeyword -O3"
.Now check the configuration log for
./configure --enable-threads
: config_threads.log, note thatFFTW_CC
is now defined as"xlc_r -O3"
and that for some reasons the script is looking forxlc_r
:Is this a bug in the configuration script?
