I wrote that is not compatible with mingw.
Thanks for the help you have given me.

I downloaded a program (lib2) that converts libreria.lib + libreria.dll in liblibreria.a;

I post:
@win32: LIBS += -L$$PWD/../LIBLIBRERIA/debug/ -llibreria

INCLUDEPATH += $$PWD/../LIBLIBRERIA/debug
DEPENDPATH += $$PWD/../LIBLIBRERIA/debug

win32:!win32-g++: PRE_TARGETDEPS += $$PWD/../LIBLIBRERIA/debug/libreria.lib
else:win32-g++: PRE_TARGETDEPS += $$PWD/../LIBLIBRERIA/debug/liblibreria.a@

but I leave the following errors:
undefined reference to imp_zn5……….Ev
undefined reference to imp_zn5……….Eb
undefined reference to imp_zn5……….Esb
...
...
...

one for each function that should be called from libreria.lib or libreria.dll

You have a static library, ending with .lib, and you want to include it in your project, which uses MinGW. As far as I know, this is not possible. LIB files come from MSVC compiler, which is not compatible with MinGW. MinGW expect .a files.

You need to either switch to dynamic libaries (DLLs), or get a MinGW build of your Liberia library, or switch to MSVC yourself.

I only libreria.lib and libreria.dll;
liblibreria.a inserts it when I insert library with add library.
I do not know what liblibreria.a.
You can explain it to me?

Please check that the libliberia.a is located in the directory specified in the .pro file. You can also modify the LIBS variable call to point specifically to the libliberia.a file.

I add library - external library - I select libreria.lib - put static

I created the following code:
@win32: LIBS += -L$$PWD/../LIBLIBRERIA/debug/ -llibreria

INCLUDEPATH += $$PWD/../LIBLIBRERIA/debug
DEPENDPATH += $$PWD/../LIBLIBRERIA/debug

win32:!win32-g++: PRE_TARGETDEPS += $$PWD/../LIBLIBRERIA/debug/libreria.lib
else:win32-g++: PRE_TARGETDEPS += $$PWD/../LIBLIBRERIA/debug/liblibreria.a@

I have two questions at this point:
liblibreria.a is it?

if little man liblibreria.a come out these errors:
undefined reference to imp_zn5……….Ev
undefined reference to imp_zn5……….Eb
undefined reference to imp_zn5……….Esb

what do I do?
