Thanks Binny for your prompt reply. Yes , it didnt make any sense to me either since I havent modified any PJSIP source code. The compilation flags and linker flags only point to iphone OS system root and? ARM binaries for system libraries. Are there any special Compilation flags that must be passed to aconfigure for Cross-compiling pjsip libraries ? Also, since platform is arm-apple-darwin9 , do I need to create a new file in pjproject build directory (something like os-arm-darwin.mak ??) ? Is DPJ_AUTOCONF = 1 correct ?

Why is not able to reference main from crt1.0 By the way, I was able to cross-compile a simple hello world file using the same set of compiler and linker flags. But it doesnt seem to work with PJSIP code. The step above is supposed to only compile file_access_unistd.c rather than compile+link it, so the link error above doesn't make any sense. Looking briefly into the command line, it looks like it's missing the "-c" option (which tells the compiler to just compile it). I don't know why, perhaps the options in the aconfigure somehow upsets something, but I think that's the reason. I don't have any clue about iPhone development of course.
