"make -j8 of face_swap" error / IplImage temp = img

[Jackpot2]

Hello there! Well, i went through your "ubuntu installation" step by step and everything went well until the make of face_swap. (i used opencv 3.4.9 instead of 3.2.0 tho.. but all other versions same as your guide.)

Here is the output from cmake command(maybe it helps your error);
/face_swap/build# cmake -DWITH_BOOST_STATIC=OFF -DBUILD_INTERFACE_PYTHON=ON -DBUILD_SHARED_LIBS=OFF -DBUILD_APPS=ON -DBUILD_TESTS=OFF cmake -DCMAKE_INSTALL_PREFIX=~/installations/face_swap -DCMAKE_BUILD_TYPE=Release ..

then when i try to "make -j8" our error shows up..

Maybe because of the OpenCV version, i'm missing some modules or differences between versions or what? i'm not sure so i wanted to write here maybe some other person comes with this error or so.. I will try again with other versions of opencv when i have time for that so we can see if its about opencv or not.. But of course it could be about face_swap codes too because it says "conversion from const to non-scalar type etc.." maybe you want to check out. Peace !

Well, i fixed it with changing some opencv files so, i wanted to share..

edit the "/usr/local/include/dlib/opencv/cv_image.h" file and change the 37th line

IplImage temp = img;

to

IplImage temp = cvIplImage(img);

or comment and add another etc..

but still, after "make -j8" of face_swap shows up,

seems like about ldconfig or so but i'll let you know if i fix this too later on..
