Qt 6.10.0 building from sources. GNU C++ compiler error: unrecognized command-line option ‘-R’ while using GCC 14.3.0

Mansur Galimov

Hi. I configured QT 6.10.0 from sources using following command:
$ ./configure -shared -no-opengl -- -B build/ --fresh
After that, It gave me usual and error-free output:

-- The CXX compiler identification is GNU 14.3.0
-- The C compiler identification is GNU 14.3.0
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done

-- Setting build type to 'Release' as none was specified.

-- Configuration summary has been written </my/path/to/summary>

-- 

Qt is now configured for building. Just run 'cmake --build . --parallel'

Once everything is built, you must run 'cmake --install .'
Qt will be installed into '/usr/local/Qt-6.10.0'

To configure and build other Qt modules, you can use the following convenience script:
        /usr/local/Qt-6.10.0/bin/qt-configure-module

If reconfiguration fails for some reason, try removing 'CMakeCache.txt' from the build directory
Alternatively, you can add the --fresh flag to your CMake flags.

-- Generating done (1.0s)
-- Build files have been written to: </my/path/to/builddir>

So, process of compilation (2-nd step of Qt compilation procedure) have interrupted at the middle of it by the following error:
c++: error: unrecognized command-line option ‘-R’
[727/1726] Building CXX object src/gui/CMakeFiles/Gui.dir/painting/qdrawhelper.cpp.o
My toolchain:

GCC 14.3.0 (self-compiled, not distribution package)
Ninja (1.13.2)
cmake 4.4.0rc3.
So, what is the solution of aforementioned error and have you ever seen that types of errors in your practice?
Thanks

Hi,

Never saw that error on builds.
Can you try to grab the exact build command that triggers that issue ?

Mansur Galimov

@SGaist Yes, here it is:

@Mansur-Galimov said in Qt 6.10.0 building from sources. GNU C++ compiler error: unrecognized command-line option ‘-R’ while using GCC 14.3.0:

-R/usr/lib64

-R is not an option recognised by gcc or g++ (though there is a -rpath if that was intended, may have been -R in the past?), and I don't think by clang either. Your /usr/local/bin/c++ should be a soft/symbolic link pointing to the actual compiler/linker you are using? Ah, from output you are indeed using gcc?

SGaist

@JonB AFAIK, it's a linker operation so somewhere there's a -Wl, that went missing from what it seems.

Mansur Galimov

@JonB Thanks a lot.
@SGaist Thanks a lot. You are completely right. That is CMake issue of generating Ninja build code.
I edited build.ninja file with the following terminal command $ sed -Ei 's/-R/-Wl,-R/g' build/build.ninja and compilation succeed.
P.S. CMake 4.3.3 executable had been tried but hasn't succeed too.
It seems that is CMake's fault, but not configure or anything else.
@SGaist, @JonB Where can I report about that error?

SGaist

I just saw that you were using a release candidate from cmake.
Can you try with an official release ?
