||||
|
||||
1. Download the official fftw64 DLL package from http://www.fftw.org/download.html,
|
||||
unpack it somewhere you can reach it with MSYS
|
||||
(Hint: in MSYS console to change directory to 'C:/DirName' execute 'cd /C/DirName')
|
||||
|
||||
2. in MSYS command line, execute:
|
||||
dlltool --def libfftw3f-3.def --dllname libfftw3f-3.dll --output-lib libfftw3f-3.a
|
||||
dlltool --def libfftw3l-3.def --dllname libfftw3l-3.dll --output-lib libfftw3l-3.a
|
||||
dlltool --def libfftw3-3.def --dllname libfftw3-3.dll --output-lib libfftw3-3.a
|
||||
|
||||
This will generate generate 'libfftw3f-3.a.a' file
|
||||
|
||||
3. copy files:
|
||||
libfftw3f-3.dll -> MinGW64/bin
|
||||
libfftw3l-3.dll -> MinGW64/bin
|
||||
libfftw3-3.dll -> MinGW64/bin
|
||||
libfftw3f-3.a.a -> MinGW64/lib
|
||||
fftw3.f.h -> MinGW64/include
|
||||
|
||||
4. Create a new textfile MinGW64/lib/pkgconfig/fftw3f.pc with the following contents:
|
||||
|
||||
prefix=/mingw64
|
||||
exec_prefix=${prefix}
|
||||
libdir=${exec_prefix}/lib
|
||||
includedir=${prefix}/include
