Compile Error

[dafrasaga]

Hi All, I downloaded last git version of gmic and gmic-qt and typed

git clone https://github.com/dtschump/gmic.git git clone https://github.com/c-koi/gmic-qt.git make -C gmic/src CImg.h gmic_stdlib.h cd gmic-qt

mkdir build cd build

cmake .. -DGMIC_QT_HOST=gimp -DGMIC_PATH=/root/git/gmic/src/ -DCMAKE_BUILD_TYPE=Release make -j5

but I had:

`-- Using CMake version: 3.15.2 Building for target host application: gimp G'MIC path: /root/git/gmic/src/ Found G'MIC repository Found /root/git/gmic/src//CImg.h Found /root/git/gmic/src//gmic_stdlib.h CImg version is [270] G'MIC version is [270] -- Found FFTW3 -- FFTW Found Version: -- Found OpenMP_C: -fopenmp

Hi c-koi it worked bu now it doesn't compile:

I suspect this is related to a missing -lfftw3_threads that should be added. This thing is a bit annoying, because not all systems define a separate library for supporting FFTW threads (sometimes, fftw-threads are just a part of the compiled libfftw, as on Windows).

[dafrasaga]

Hi David, as a simple user as I am do you advice something?? Who would add -lfftw3_threads and where ?

[dtschump]

@dafrasaga , don't worry, I think this should be fixed by @c-koi soon. I had lunch with him today and we talked about this issue :)

Should be fixed by 9e98ec8d86c606b12d5caa58e7c762fed52dc2f4

Hi c-koi, thanks thanks thanks. It worked!! It's as in this moments I like FOSS.
