[Interest] Qt 5 Cross compile issue in freescale IMX53 Board

Sun Dec 30 13:13:58 CET 2012

Hi All,

I successfully compiled Qt 5.0.0 for IMx53 Board.

I configured with -eglfs and -opengl es2 options.
My cross compilation was successful.

When I run application , i got below error message.

./hellogl_es2 -platform -eglfs

Hi,

I installed XCB in sysroot directory.

And also I included sysroot in configure command like this,

./configure -v -prefix /usr/local/Qt-5.0.0 -xplatform linux-g++-mx5x -opensource -nomake examples -nomake demos -nomake tests -no-opengl -qt-xcb -qpa xcb -no-directfb -release -shared -fast -no-largefile -no-accessibility -no-sql-db2 -no-sql-ibase -no-sql-mysql -no-sql-oci -no-sql-odbc -no-sql-psql -no-sql-sqlite -no-sql-sqlite2 -no-sql-tds -no-c++11 -no-javascript-jit -qml-debug -no-sse2 -no-sse3 -no-ssse3 -no-sse4.1 -no-sse4.2 -no-avx -no-avx2 -no-neon -no-mips_dsp -no-mips_dspr2 -qt-zlib -qt-libpng -qt-libjpeg -no-openssl  -no-eglfs -qt-pcre -optimized-qmake -no-nis -no-cups -no-iconv -no-icu -no-strip -no-dbus -no-separate-debug-info -no-kms -no-glib  -I/usr/include/freetype2 -sysroot /opt/freescale/usr/local/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/arm-fsl-linux-gnueabi/sysroot/

When I execute above command ,I got some other erros like,

/opt/freescale/usr/local/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/bin/../lib/gcc/arm-fsl-linux-gnueabi/4.4.4/../../../../arm-fsl-linux-gnueabi/bin/ld: crt1.o: No such file: No such file or directory

You need to install the XCB libraries in your sysroot.

Please use the interest at qt-project.org mailing list for such issues instead of

emailing me directly.

Hi thiago.macieira

I have a problem to build xcb library.
i got following error when i configure Qt 5 with -qt-xcb and -qpa xcb options.

I installed all the xcb libraries which are specified in Read me file and also i included xcb header file and library file location in configure path.

 You might need to install dependency packages for libxcb.
