Problem crosscompiling qtopia-core4 with buildroot
Message 1 in thread
Hi,
I have some problem while cross-compiling qtopia-core4 with buildroot.
Buildroot creates a cross-compilation toolchain with the uClibc
libraries.
The following configure line is executed:
# Patching configure to get rid of some feature I dont want.
# (I don't want SQL either but there is no option for that at all.
# the SQL library will be built even without the plugins/drivers.

(Many other lines like the last one follows).
The problem is that LD looks for the wrong libc, the host ones instead
of the target one (that are located in /opt/cross/...)
What am I wrong? I think that something in the configuration line is
bad.
Thanks in advance!

IIRC, the environment variable LD_LIBRARY_PATH has to be set correctly.
I did not compile neither qtopia-core4 nor buldroot though. I am with
qt-embedded3.
Hope that helps,
Andre

Hi Andre,
Thank you for your response.
The problem is that the qmake and make chain confuses the host compiler
and linker (g++) with the target cross-compiler (i586-linux-uclibc-g++).
I have tried to compile qtopia "outside" buildroot with no luck.
But after
- Creating a new mkspecs/qws/linux-x86-uclibc-g++/qmake.conf file,
- Removed the -I and -L options from configure
- Changed -target x86 with -target x86-uclibc
- Removed some ENV vars (GCC and CXX) that was confusing the make
it started compiling without error an any stage (for now), tools and
corelib is compiled correctly, for now.
Thank you very much again.
