I am not familiar with scratchbox to try and set up a build environment, but if someone wants to have a go it, I might be able to help with resolving the last remaining issues.

Sorry if you've already answered, but where are the checkout/build instructions for libcvm?

sharing the code and buildinstructions is great.

If you want to build libcvm with scratchbox for crosscompiling, just
change the first line of your build script from
export CVM_TARGET_TOOLS_PREFIX=/opt/arm-2011.09/bin/arm-none-linux-gnueabi-
to
export CVM_TARGET_TOOLS_PREFIX=/scratchbox/compilers/cs2007q3-glibc2.5-arm7/bin/arm-none-linux-gnueabi-

So, building the cvm application works, but

compiling Qt4 cvm application gives the following errors:
build/main.o: In function `resetFrameBufferSize(int, int)':
/tmp/build_phoneme//Downloads/cvm/src/main.cpp:229: undefined reference to `resizeFrameBuffer'
/tmp/build_phoneme//Downloads/cvm/src/main.cpp:231: undefined reference to `resizeFrameBuffer'
build/main.o: In function `cvm_exec()':
/tmp/build_phoneme//Downloads/cvm/src/main.cpp:146: undefined reference to `cvm_main'
build/main.o: In function `main':
/tmp/build_phoneme//Downloads/cvm/src/main.cpp:618: undefined reference to `initPixmap'
/tmp/build_phoneme//Downloads/cvm/src/main.cpp:620: undefined reference to `initPixmap'
/tmp/build_phoneme//Downloads/cvm/src/main.cpp:624: undefined reference to `initDrawChars'
/tmp/build_phoneme//Downloads/cvm/src/main.cpp:626: undefined reference to `initPlatform'
/tmp/build_phoneme//Downloads/cvm/src/main.cpp:628: undefined reference to `initGPS'

any ideas?

one with "export CVM_BUILD_SO=true"
has just more errors:

lib/libcvm.so: undefined reference to `pcsl_string_cat'
...
lib/libcvm.so: undefined reference to `pcsl_file_getusedspace'

I was afraid this would happen. The CVM_BUILD_SO is a feature that was already available in the phoneME source tree and noticed it recently while going through the build configuration files, but it does not seem to be compatible with what I need. I just compared the build commands and indeed several libs are not included.

Before, I used dlopen and dlsym routines to load the libcvm.so from the phoneme dir in /opt, but this was a mess as I had to create function pointers for all relevant methods.

If I can find a way to build the phoneME Qt4 front end and also have it look for libcvm.so in other directories than /usr/lib etc. then this is issue is solved.

PS: I am fully aware of the LD_LIBRARY_PATH environment variable, but I do not consider this as a proper solution.
