Help build Qt5.15.2 with aarch64-linux-gnu-g++

[Balaton]

Hello! I want to build Qt5.15.2 with aarch64-linux-gnu-g++. Cross compiler gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu. Qt5 qt-everywhere-src-5.15.2.tar.xz.
Configure:

../qt-everywhere-src-5.15.2/configure -release -no-opengl -linuxfb -device linux-arm-generic-g++ -device-option CROSS_COMPILE=/opt/qt5rock/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu- -sysroot /opt/qt5rock/sysroot/ -gcc-sysroot -prefix /usr/local/qt5pi -extprefix /opt/qt5rock/targetBinaries -hostprefix /opt/qt5rock/hostBinaries -opensource -confirm-license -skip qtscript -skip qtwayland -skip qtwebengine -nomake tests -make libs -pkg-config -no-use-gold-linker -v -recheck -I /opt/qt5rock/sysroot/usr/include -I /opt/qt5rock/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu/aarch64-none-linux-gnu/libc/usr/include -L /opt/qt5rock/sysroot/lib -L /opt/qt5rock/sysroot/usr/lib/aarch64-linux-gnu

After configure I get a lot of similar errors. An example is one of them:

The linker does not see certain bob libraries, although they are present in the folders specified in the -L switch.

libwebp.so.6
libzstd.so.1
liblzma.so.5
libjbig.so.0
libjpeg.so.62
libz.so.1

Someone can tell you how to correctly tell the linker where to get these libraries.

Hi and welcome to devnet,

What do you mean by bob libraries ?

Are you sure these librairies you point to are of the correct architecture ?

@SGaist Me direns that OP meant blob...........

Whatever he meant, I think that shitty compilator ( dcc ), upon being dinted, should:

• look for deps and install All ( SCREW you utf )
• relink libs
