Link ZeroMq and Qt 32bits

Thombou

Hi
I want to build an application with ZeroMq.
I have a constraint that I need to use 32bits on windows.

I downloaded a lib file from the github repository of ZMQ https://github.com/zeromq/libzmq/releases/tag/v4.3.4. I downloaded the v140 version, which is with x86 architecture (I checked with dumpbin command).
To add this lib to my project, I use the wizard. I select the file and I get the following lines

win32: LIBS += -L$$PWD/../../../Softwares/ZMQ/libzmq-v140-4_3_4/ -llibzmq-v140-mt-s-4_3_4

INCLUDEPATH += $$PWD/../../../Softwares/ZMQ/libzmq-v140-4_3_4
DEPENDPATH += $$PWD/../../../Softwares/ZMQ/libzmq-v140-4_3_4

Then I run clean, run qmake and finally build.
No matter what I try, I always get the error as shown in the picture below. unresolved external symbol which for me means that the library is nto properly linked.
How can I debug this and find out what is wrong?

I use: Qt 5.12.2 MSVC 2019 32bits

Thank you very much!

Since I'm on Windows, it should still be -llibzmq-v140-mt-s-4_3_4. However for this library to work, a preprocessor directive ZMQ_STATIC needs to be added

@Thombou said in Link ZeroMq and Qt 32bits:

-llibzmq-v140-mt-s-4_3_4

That should be

-lzmq-v140-mt-s-4_3_4
