Quazip and Qt6 mingw

apaczenko1993

Is it possible to compile the quazip library for Qt 6.5.2 using the mingw compiler? Initially, I found information that it was not, but I would like to make sure 😀 if it is true, do you have any other ways to pack files into a ZIP archive?

Why should it not be possible? Just try it out.

apaczenko1993

This is the first time I will try to create a dll file myself, so I will let you know if I have any problems

apaczenko1993

So i dowload the zlib_source and a beginning i ahve a problem with build zlib.
I try use instruction from: Build instruction

I have install cmake from qt maintanance tool.
After pass commands from instruction i have this error, I know that is a problem with compiler, how can i set it?

Does https://stackoverflow.com/questions/70524164/cmake-c-compiler-not-set-after-enablelanguage help?

cmake -DCMAKE_CXX_COMPILER=/pathto/g++ -DCMAKE_C_COMPILER=/pathto/gcc /pathto/source

Is your MinGW compiler on your PATH?

apaczenko1993

@JonB You mean in environment variables??
Actual no, but i add, this: C:\Qt\6.5.3\mingw_64\bin
Is it ok?

JonB

@apaczenko1993
-DCMAKE_C_COMPILER=/pathto/gcc is not an environment variable (though you might be able to do that, I don't know)m it's a define to cmake (and I don't know whether it puts that into environment or just uses it directly).

But I think the references said you could put mingw_64\bin on your PATH. "Is it ok?" --- I don't know, does it make things work for you?!

@apaczenko1993 You should simply build in the terminal provided by your Qt installation - you will find it in Windows Start menu. In that case everything is preconfigured to build with MinGW.

apaczenko1993

Ok , so i tried again with setting compiler and now i get this

Setting up environment for Qt usage...

I have in zlib folder file named configure but i dont know how use it

JonB

@apaczenko1993
I do not have MinGW. You have set C:\Qt/Tools\mingw1120_64\g++.exe. Are you sure that is the right directory? It does not have a bin\ sub-sirectory?

apaczenko1993

Of course has, my mistake. But still same result :/

@apaczenko1993 Please do what @jsulm told you to set up the compiler environment correctly. Also start over with a clean build dir and pass -G "MinGW Makefiles" to the cmake call and don't pass MAKE_CXX_COMPILER and CMAKE_C_COMPILER

apaczenko1993

@Christian-Ehrlicher Thank you! So first step complet, next quazip

apaczenko1993

@apaczenko1993 Now during compiling quazip i have this error

You have msys in your PATH - remove it and start over with a clean build dir.

apaczenko1993

@Christian-Ehrlicher said in Quazip and Qt6 mingw:

ean build dir.

Can you explain what is msys?

Christian Ehrlicher

Somewhere in your PATH env var you have a bash.exe, sh.exe or similar so the directory separators are messed up (/ <-> \) and the compilation is failing.

apaczenko1993

Ok finally builded, thanks for help :)
