Hi,
I am trying to use third party PDF viewer library libmupdf compiled successfully in MS visual studio(32 bit), But I am facing issues when I am trying to build sample application in QT.LINK : warning LNK4098: defaultlib 'LIBCMTD' conflicts with use of other libs; use /NODEFAULTLIB:library
QT version : 5.9 community edition ( MSVC2015 32 bit compiler ).
mupdf version: mupdf-1.12.0-source.tar.gzhttps://mupdf.com/docs/index.html
#include <mupdf/fitz.h>
int main(int argc, char **argv)

Now I am able to compile, I have to move my release lib to debug lib folder in order to deal with some link issues.

@Aditya1309 This is a warning. Are there any errors? Is you app working?
-
Its not working, I am not able to get it compiled.

@Aditya1309 This is a warning. Are there any errors? Is you app working?
-
@jsulm I am facing linking issues, But I have included libmupdf and libthirdparty compiled from source code.
@Aditya1309 What other issues do you have? Because the one you posted is a warning, not an error.
Can you show your pro file? -
Now I am able to compile, I have to move my release lib to debug lib folder in order to deal with some link issues.

You should remove the lib prefix:-lmupdf -lresources -
Its complaining that -lmupdf is not found.
