Could someone please clue me in on how to use these when cross-compiling? Is there some docs somewhere that show this?



I am compiling on the build system with my install directory at /usr/local/arm/lib, which is the root of the cross-compiled file system. If I tell my app (konqueror embedded) to compile with libs at /usr/local/arm/lib, then konqueror looks for its libs there when it is run.... But if I tell it to use /lib, then the compile will fail because it finds incompatible libs (x86) there...



I am missing something, I know.... Is there a doc somewhere on how to use these? What do others use in their config scripts?



Thanks,

Yan,

Your cross-compiler toolchain should already know to look in /usr/local/arm/lib for all the standard libraries. If there are additional libraries that konqueror needs at compile-time, then you will probably have to specify them by hand on the compile line. Try setting the CFLAGS environment variable to -I/usr/local/arm/include and LIBS -l/usr/local/arm/lib and running configure again - hopefully it will detect these and build them into the appropriate Makefiles.

Regards,

Yeah, I discovered that my dev box had gcc 4.1 installed, which was causing all the trouble.... I must have installed it by accident / carelessness / stupidity (apt-get dist-upgrade instead of apt-get upgrade may have been one way....)

The toolchain just will not build correctly with gcc 4.1.
