Hi,
Does the compiler emit any warning?
No, no warnings.
Remember that if it makes your life easier, you can directly define cur and ret of type char*.
Thanks, it does make it easier and more readable. Doing this causes no warnings: char *cur; char *ret; cur = (char*)&test_CurrentIP; ret = (char*)CurrentIP();
Well, I think you can just probably just declare it in the source, either in the test function or outside of it. There's some examples of that in existing tests, see e.g:
I see, thanks for the examples. I took a look at them and put this in tests/main.c: extern void *WINAPI CurrentIP(void); Doing this, the 64-bit test compiles without a problem, but the 32-bit runs into this problem: /usr/lib/gcc/i686-w64-mingw32/11.2.0/../../../../i686-w64-mingw32/bin/ld: dlls/wdscore/tests/main.cross.o: in function `test_CurrentIP': src/wine-staging-32-build/../wine-staging/dlls/wdscore/tests/main.c:33: undefined reference to `CurrentIP(a)0' /usr/lib/gcc/i686-w64-mingw32/11.2.0/../../../../i686-w64-mingw32/bin/ld: /src/wine-staging-32-build/../wine-staging/dlls/wdscore/tests/main.c:33: undefined reference to `CurrentIP(a)0' collect2: error: ld returned 1 exit status winegcc: /usr/bin/i686-w64-mingw32-gcc failed make[1]: *** [Makefile:228478: dlls/wdscore/tests/wdscore_test.exe] Error 2 Removing WINAPI from the declaration allows it to compile: extern void *CurrentIP(void); I don't understand why this is happening. What am I missing? The same error happens if I add a header file and import it. The dll wlanapi also has a void* function (void *WINAPI WlanAllocateMemory) and I don't see anything that might be missing in wdscore. Is there a missing header? I tried adding windows.h and other headers from similar dlls but it still says undefined reference to CurrentIP. Why would it work on 64-bit but not 32-bit? I had a similar problem in the past with UiaRaiseAutomationPropertyChangedEvent but that was due to an incorrect spec file parameter. As far as I know, the spec parameter should be empty for 0 arguments and this is indeed how it is with other dlls: ./dlls/powrprof/powrprof.spec:2:@ stdcall CanUserWritePwrScheme () ./dlls/user32/user32.spec:365:@ stdcall GetProgmanWindow () ./dlls/ws2_32/ws2_32.spec:71:@ stdcall WSACreateEvent () Sorry for all the questions, I hope I'm not annoying anyone.
