mpb 1.5 installation on osx 10.10.4

[ehchen]

It seems when I try to configure MPB, I get the following error, even though I had done "brew install fftw" ran without errors:

configure: error: The FFTW libraries could not be found. Make sure FFTW is installed, and that LDFLAGS and CPPFLAGS are set appropriately if necessary.

I did in fact set my LDFLAGS and CPPFLAGs before running ./configure:
export LDFLAGS=-L/usr/local/opt/fftw/lib
export CPPFLAGS=-I/usr/local/opt/fftw/include

Look in the config.log file for "-lfftw3" and see what error is occurring when it tries to link the libfftw3 library.

I have the same problem two years later, and here is the what one finds:
configure:16663: checking for fftw_execute in -lfftw3
configure:16696: gcc -o conftest -g -O2 -Wall -W -Wbad-function-cast -Wcast-qual -Wpointer-arith -Wcast-align -pedantic -I/usr/local/include-I/usr/local/Cellar/hdf5/1.10.1/include-I/usr/local/opt/fftw/include-I/usr/local/Cellar/fftw/3.3.6-pl2/include -L/usr/local/lib-L/usr/local/Cellar/hdf5/1.10.1/lib-L/usr/local/opt/fftw/lib-L/usr/local/Cellar/fftw/3.3.6-pl2/lib conftest.c -lfftw3 -lm >&5
ld: library not found for -lfftw3

-I/usr/local/include-I/usr/local/Cellar/hdf5/1.10.1/include-I/usr/local/opt/fftw/include-I/usr/local/Cellar/fftw/3.3.6-pl2/include is clearly wrong because the -I options aren't separated by spaces. See also #20.

Please don't file multiple github issues for the same problem. Just add additional comments to the original issue as needed.

Thanks and sorry for all the dumb stuff…I am somewhat new at this, and finally it dawned on me about the spaces. Also, I figured how to edit the original comment to minimize the dumb stuff. It will get better fairly rapidly, and I will spew less garbage all over GitHub site.

No problem.
