Description
Linker throws error when trying to compile a simple program from .pro file that uses Catch library:
#define CATCH_CONFIG_MAIN #include "catch.hpp" TEST_CASE("test", "[test]") { REQUIRE(1==1); }
TEMPLATE = app
CONFIG -= qt
CONFIG += cmdline c++11
HEADERS = catch.hpp
SOURCES = test.cpp
This happens when using kits Qt 5.9.4 msvc 2015 32bit and Qt 5.13.1 MinGW 7.3 32bit, but doesn't happen with Qt 5.13.1 msvc 2017 64bit kit.
Invoking compiler directly on the command line (cl / g++) succeeds in all the above cases. This leads me to think that qmake is guilty, maybe some mkspecs settings?
I also tried to use qbs instead of qmake: both msvc builds succeeded, but for MinGW I had to add DO_NOT_USE_WMAIN define that forces Catch to create main instead of wmain, see here. The same define had no effect on qmake.
Someone has already faced this issue: https://github.com/catchorg/Catch2/issues/1287, but the workaround from there still doesn't solve error in msvc 2015 with qmake.
Actual linker errors:
MSVC 2015 (for w/e reason it uses subsystem windows, I tried to force console through QMAKE_LFLAGS, but that didn't help either)

Just in case linker output from MSVC 2017 (this one was done by invoking qmake without options on command line and then running nmake):
