QT. QImage: No such file or directory
-
Hi all,
I am trying to run a C++ code from Cython and get this error message.
I have QT installed and all the files and libraries intact.
I tried to run the C++ project from qt creator and it works but when I try to run it from Cython I get this error.$python setup.py build_ext --inplace running build_ext building 'c_inpainting' extension creating build creating build/temp.linux-x86_64-3.7 gcc -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/include -fPIC -I. -I/home/xxxx/miniconda3/include/python3.7m -c c_inpainting.cpp -o build/temp.linux-x86_64-3.7/c_inpainting.o cc1plus: warning: command line option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++ In file included from imgCodecs/inpainting.cpp:3, from c_inpainting.cpp:651: imgCodecs/supplementary_functions.h:6:10: fatal error: QImage: No such file or directory 6 | #include <QImage> | ^~~~~~~~ compilation terminated. error: command 'gcc' failed with exit status 1Furthere I tried to do a cmake of the file normally and on running make I get this error

You should maybe ask the library devs what you need where. What library are you trying to compile? What was the cmake output during configure? Was Qt properly found?
-
How should I include the library dev guys here?
I am trying to include QDialog QMessageBox QPixmap QFileDialog QFile QImage. which the code uses.
this is my MakeFile2 generated.

I don't want to see your Makefile. This can't read nor understand anyone.
What are you trying to achieve? How does your CMakeLists.txt look like - are you searching for the Qt libraries there? Where is your main.cpp where you instantiate your QApplication object? -
thats my CMakeList.txt. I am not searching for the QT libraries there yet.

#include "imgcodecs.h" #include <QApplication> int main(int argc, char *argv[]) { QApplication a(argc, argv); ImgCodecs w; w.show(); return a.exec(); } -
So you should do this like explained e.g. here.
