Hello, It is clear to me that in an easyconfig for a ConfigureMake easyblock the configopts variable contains the options for the configuration step. However it is not fully clear to me what happens when instead of a single string configopts is a list of strings, like in this case taken from FFTW-3.3.5-gompi-2016.07.eb:
configopts = [ common_configopts + " --enable-single --enable-sse2 --enable-mpi", common_configopts + " --enable-long-double --enable-mpi", common_configopts + " --enable-quad-precision", common_configopts + " --enable-sse2 --enable-mpi", # default as last ] My best guess at the moment is that EB will try one string at a time and, if the configure step fails, it will try the next in the list. Am I correct? I tried to look in the doc but I could not find an answer. Unless I missed it (higly probable) I would suggest adding a couple of lines under "Configure/build/install command options" .
