Error when building Qt5.15.16 from source

Gravit22

@Christian-Ehrlicher I do not understand. My Perl version is v5.38.2 and cmake version is 3.28.3.
As I understand it is relatively recent. What exactly is outdated?

It Is Qt5 what is the version of mingw64 used?

@Gravit22 said in Error when building Qt5.15.16 from source:

My Perl version is v5.38.2 and cmake version is 3.

Neither of them is your compiler... You need a recent gcc

Gravit22

@Christian-Ehrlicher My gcc version is:
gcc (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0
Also seems not too bad
@piervalli as I understand this is my mingw64 version

Sorry usually I use Windows instead of Linux the same version of Qt Ubuntu 20.04, you can find on release notes which is the distro used.

@Gravit22 it looks like an older version is used. What does 'gcc - - version' say?

Gravit22

@Christian-Ehrlicher It states the version of gcc is 13.3.0

gcc (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0

Compiled on Lubuntu 20.04 64-bit
GLIBC 2.31
GCC 9.4.0


 ../qt-everywhere-src-5.15.16/configure -release -prefix "/opt/Qt/5.15.16/gcc_64" -opensource -confirm-license -silent -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -system-freetype -opengl desktop -make libs -make tools -flite -openssl-runtime OPENSSL_PREFIX="/opt/Qt/Tools/OpenSSLv3/src"

make
make install

Also - do you really need qtlocation? If not simply skip it.
