The scenario is as follows... Actually I'm building a huge application using Diab toolchain . The target RTOS (cant reveal name :-(... ) required kernel services are also built along with the application. The image is loaded into target device(powerpc machine) as a bootable image. But that RTOS doesn't have pthread support., wheras the library used by Diab-c compiler has pthread library. So it worked fine so far. Now I'm porting this application to GCC compiler. I built the powerpc-eabi cross tool chain with newlib. Since the pthread library is not part of newlib library, I guess I would face problem which porting. :-(.. I can't use Glibc since there is no support for powerpc-eabi in Glibc! How to over come this problem?
