Linker issue

[Romain.Besso]

Hi,

I'm rather new to Qt and do not have a lot of experience with C++, but I currently encounter problemes with my .pro file.
I'm currently trying to use Glib on Windows 10.
You can se above the content of my .pro file and the related error.

From what I understand it's a linker probleme for Glib, so I try differents things but I dont really understant what am I expecting to do. Anything to do with LIBS+= ?

If you have any idea, it will be usefull.

@JoeCFD Actually, I don't have that lib. How do you recommend to install it on Win 10 ?
I have MSYS2 if it can be useful.

thanks in advance

[jsulm]

@Romain-Besso said in Linker issue:

No, it is not.
Use MinGW installed with Qt to build that lib.

[Romain.Besso]

@jsulm okay, I've never used it. I will look into doing this installation.

Thanks

[JoeCFD]

@Romain-Besso your app may not use it directly, but the libs your app use need it.

[Romain.Besso]

@JoeCFD @jsulm Building a lib with mingw seems unclear to me.
Can you tell me how to do it, if you know?
thanks in advance.

@JoeCFD said in Linker issue:

__imp_WSACloseEvent

libzmq is missing
https://github.com/zeromq/libzmq/issues/2884

??

WSACloseEvent is in Ws2_32.dll so the linker needs to link against Ws2_32 ...

[Romain.Besso]

@Christian-Ehrlicher You are right, with this include I have now only one err :

C:/Qt/Tools/mingw1120_64/bin/../lib/gcc/x86_64-w64-mingw32/11.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: C:\msys64\mingw64\lib\libglib-2.0.a(gutils.c.obj):(.text+0x59b): undefined reference to `__imp_CoTaskMemFree'

I think it's related to : https://docs.microsoft.com/en-us/windows/win32/api/combaseapi/nf-combaseapi-cotaskmemfree

But i dont have that Ole32 lib

[Christian Ehrlicher]

@Romain-Besso said in Linker issue:

But i dont have that Ole32 lib

You have, it's a base windows dll similar to Ws2_32.dll
