after unzipping this file, i did a shadow building, that i create a qt-everywhere-src-5.15.2-build directory out of the src file.
i run inside the build directory, the configure file

cd ~/qt-everywhere-src-5.15.2-build
~/ qt-everywhere-src-5.15.2/configure

I should modify the ~/qt-everywhere-src-5.15.2/qtbase/src/corelib/global/qglobal.h file to avoid a first error (error : ‘numeric_limits’ is not a class template..)

Such an error is documented on the web. One should add the three first lines to the qglobal.h header file

#ifdef __cplusplus
#include<limits>
#endif

Afterthat configure is successfull and generate makefiles in the ~/qt-everywhere-src-5.15.2-build repertory

I ran then make but have the following error

I try on a second PC the same process. I note that on this other PC the output lines were different since it request that llvm-config file is in the PATH

So i add in my .basrhc file ‘export PATH=${PATH}:/usr/lib/llvm-13/bin’

In addition i add différents packages with synaptic :

I ran again make put get same error.

I did not found any information on the web on such an error
