It looks like something went wrong with the makefile generation, since there should be a -I.. -I../gsl flag passed to the compiler to locate the *.h files.

Did you try the methods here:

for windows builds? There is also a cygwin package prebuilt for gsl.

I've unpacked the gsl.tar.gz in dir gsl-2.4. In this dir I built dir
In gslbuild I startet

.././configure  --prefix=C:\Qt\Tools\mingw492_32\i686-w64-mingw32
-(I didn't make check because I didn't know that at this time)
make install

Starting from die gslbuild:
$ cd fft
$ make test
gcc -g -O2    ../../fft/test.c   -o test
../../fft/test.c:20:20: fatal error: config.h: No such file or directory
  #include <config.h>
compilation terminated.
make: *** [test] Error 1

so ./test could not be executed.

config.h is in dir gslbuild  but not in the minGW gsl include Path


nor in

   Did the library pass 'make check'. What happens if you do:

cd fft ; make test ; ./test

I installed the GSL in win10 64bit -system with minGw  and msys using
the cofigure script. The installaion seemed to work fine and  many
functions where

generated and also the standard tests worked fine.  I wanted to test
my old FFT programs and became the message "undefined reference to

`gsl_fft_real_radix2_transform'" checking both the libs libgsl.a and
libgslcblas.a  showed that this function was not in there, only  fft.o
and dft.o.

A look in the build directory showed that only fft.o and dft.o have
been produced in built dir fft. The header files where shifted to dir
gsl in built but nothing built was built there.  in dir  fft  looks not correct.

attached you'lll find the config.log
