Hello, I guess that this is the correct place to ask the following question. I've built a crosstoolchain for building Cell binaries on a x86 platform. The gcc version I used is gcc 4.3.0 . When I compile spu binaries with the corresponding main function signature... main(unsigned long long spe, unsigned long long argp, unsigned long long envp) ... I get an error telling me that the main signature is not correct (the first parameters must be and integer, etc...). spumain.cpp:56: error: first argument of 'int main(long long unsigned int, long long unsigned int, long long unsigned int)' should be 'int' spumain.cpp:56: error: second argument of 'int main(long long unsigned int, long long unsigned int, long long unsigned int)' should be 'char **' spumain.cpp:56: error: third argument of 'int main(long long unsigned int, long long unsigned int, long long unsigned int)' should probably be 'char **' I've seen in http://www.gnu.org/software/gcc/gcc-4.3/porting_to.html that C++ from version 4.3.0 has stricter requirements for function main signature. How is supposed to work this on a Cell platform? Thanks in advance, Salut!
