In this case, cross-compilation is the way to go because your system is not capable of building PJSIP from the source itself. To do the cross-compilation, you will need a development machine, e.g. laptop or dedicated PC and the right cross-toolchain, i.e. cross-compiler, cross-linker, cross-debugger, cross-binutils (if you are using GCC) and some other utilities as needed. You also need to connect to the TS-7250 board with your development machine via _both_ serial and ethernet interfaces because you will need to use the serial port to "forward" the embedded linux console to the development machine and you need the ethernet connection to download large binary images and for running the cross-debugger. It's much more convenient to use the ethernet than to "lump" everything via the serial connection. Assuming that you have all the prerequisite I explain above, then you can cross compile PJSIP. Below is an example of configuring and cross-compiling pjsip for Blackfin using GNU toolchain from the root directory of PJSIP source code: ./configure CC=bfin-uclinux-gcc --host=bfin-uclinux --build=i686-linux --with-lib-path=/opt/uClinux/bfin-uclinux/lib LDFLAGS='-Wl,-elf2flt' CFLAGS=-O2 && make dep && make To do the same thing for the ARM9, simply replace the toolchain and default library paths as needed. For example, let's say your cross-toolchain is prefixed with 'arm9-uclinux-' and the cross-library is located at /opt/uClinux/arm9-uclinux/lib, then you would invoke the following from Pjsip root directory for cross-compilation (the assumption is your development machine is an x86): ./configure CC=arm9-uclinux-gcc --host=arm9-uclinux --build=i686-linux --with-lib-path=/opt/uClinux/arm9-uclinux/lib LDFLAGS='-Wl,-elf2flt' CFLAGS=-O2 && make dep && make After the cross compilation successfully completed, you can test it by using the pjlib test and pjlib-util test binaries. They are located at /pjlib/bin/ and /pjlib-util/bin/. To test the binaries, you can run FTP on the TS-7250 board to download the cross-compiled binaries from your development PC and test them. I know, this must be a premature information.
