Hi,
I took some stuff from https://dev.openwrt.org/ticket/7649 to compile
gammu for OpenWRT on AVR32.
Most of it seems fine, but a few things fail:
- The compilation needs cmake on the host, which is not checked for.
OpenWRT does not provide support for cmake, but a host installed recent
cmake should do.
- The compilation is not cross compile aware. So the host cc is checked
for instead of the cross compiler
- Cmake fails because it cannot find libm.so. This is in
staging_dir/toolchain-*/lib. But there is no environement variable set
for this directory. The STAGING_DIR variable points to
staging_dir/target-* and something like STAGING_TOOLCHAIN_DIR is not
set. At least not when configuring the package.
- I peeked around and found that OpenEmbedded added the parameter
-DCMAKE_FIND_ROOT_PATH=${STAGING_DIR_TARGET} to cmake. When I
manually let the root path point to the toolchain dir, it seems to
compile OK.
Oops, mail escaped before I was finished typing it.
Anyway, gammu seems to work on platform. At least, it is no worse than
on a desktop PC.
My question is: what to do? How is normally libm.so detected? Maybe
someone with more experience with cmake and cross compiling can shine a
light on it. Would be very much appreciated!
Regards,
Bas.
