Issue building Squish from sources

[PLL3]

Hi everyone, I'm currently trying to build Squish from source since we need to automate the tests on a statically linked Qt application.

I've been following the instructions found here.

However i'm faced with an error : "Skipping qmake output: Could not find qmake spec 'win32-msvc'." Here's the content of the generated config.log :

Please verify if qmake works correctly outside of Squish.

From my (limited) understanding, the issue is that QMake can't seem to find my c++ compiler. I've never used QMake before (since I used CMake to build my version of Qt6.2.6, which could explain why my QMake "isn't set up".
I think that "E:\Qt\Qt6.2.6\qt-install-6.2.6\mkspecs\win32-msvc\qmake.conf" being basically empty (it's just a boilerplate right now) is the core issue, but I have no idea on how fixing that correctly or even what to add if I were to manually fill that file.
I've tried searching online to no avail :(

Thanks in advance for your help !

PS : It occured to me that having the command line used to build my version of Qt might be relevant so here goes :
(called from an empty "build" folder next to the sources folder)

CALL ..\qt-src-6.2.6\configure -prefix E:\Qt\Qt6.2.6\qt-install-6.2.6 -release -static -feature-relocatable -qt-zlib -qt-libpng -qt-libjpeg -qt-pcre -qt-freetype -qt-harfbuzz -submodules qtbase,qtsvg

@PLL3 Do you call configure from the terminal provided by your Qt installation? This is important because it configures the environment properly.

Hi, I'm not sure I fully understand what you mean. I've looked through most of folders of my Qt install, the Qt build and even the Qt sources folders, and I haven't been able to find a terminal/command line app.

Do you maybe mean the terminal I used to build/install Qt should be re-used for building Squish ?

[jsulm]

@PLL3 Look in Windows start menu, it should be there (Qt installer adds menu entries there). Also your Qt installation for sure has it in the installation folder.
See https://stackoverflow.com/questions/24219732/where-can-i-found-qt-5-3-0-command-prompt

@jsulm I have found the terminal you talked about, and sadly it didn't solve my problem, I have the exact same error as before.
Using this new terminal, I tried all the things I had already tried, same result everytime :s

I was confused because my Qt installation truly did not have such a terminal. I had to download a Qt6.2.6 version from the downloader/installer, I could then see the Qt terminal in my start menu and there was a qtenv2.bat file in the newly made install folder.

But that newly downloaded Qt6.2.6 version is not the one I need to use. Our application is using a custom static library of Qt6.2.6 that I built myself from the sources using CMake. This is the one that I need to use with Squish, not the one I just got from their installer.

But for some reason my custom qt build does not have this "qtenv2.bat".

Right now I'm thinking that it's the way I build my version of Qt6.2.6 that causes the issue. I must've missed an option used for setting up Qmake and such.

@PLL3 You should retry from a clean build folder without build artefacts from your previous attempts.

[PLL3]

@jsulm I already do that, my build script wipes the folder before starting anything. Since making this post yesterday, I've must've rebuilt Qt close to a dozen time, all giving the same message when trying to build Squish afterward.

Here's the command line used to build my Qt :

CALL ..\qt-src-6.2.6\configure -prefix E:\Qt\Qt6.2.6\qt-install-6.2.6 -release -static -feature-relocatable -qt-zlib -qt-libpng -qt-libjpeg -qt-pcre -qt-freetype -qt-harfbuzz -submodules qtbase,qtsvg

It's a pretty simple call with not a lot of options/arguments, not really sure what's going wrong there.

After that i simply call

cmake --build . --parallel
cmake --install .

As instructed in the doc.

So far I've had no issues using the produced libs in our app.
From my understanding the issue I have is Qmake not being correctly setup/initialized, but since Qmake is being phased out I've been using CMake from the start. Before making this post I tried building my custom Qt6.2.6 using Qmake, in the hopes that Qmake would then "work", but I don't think it's possible.

[PLL3]

Hi all, I've managed to find a "solution" for my issue. All you need to do is add a "qt.conf" in the /bin folder of your Qt installation folder.

And this file contains the following :

Prefix=..

Hope this helps someone in the future.
