Hello, I apologize since this can be considered OT. But I've googled this, read man, website and still haven't found what I'm looking for. I write mainly fortran code. Someone in our research group wrote a C code and compile it with GCC-3.2 (RH 9). For compatibility reasons with other libraries, all of our Fortran code is compiled (/w absoft compiler) using some flags so that the resulting symbol name is all lower case plus one trailing underscore, eg: my_math_solver_ , matrix_multiply_ , etc. Now, when we compile this C code, the resulting symbol name is just lowercase. What I am looking for is the correct flag for GCC so that the resulting symbol name is lowercase plus one trailing underscore, otherwise, calling this function from Fortran code will result in "undefine reference to symbol_name_ " during linking, since if I do "nm" to toe object file, it's defined as "symbol_name". So, is there a flag that will do this? Furthermore, could you point me what are all the available flags for this sort of things and where to find it? I've read the manual and all, but I still get the felling I'm missing something, because once in a while I would find few things scattered of the web that's not in the manual, but works. I just want a comprehensive list of all this thing in one place. Also, if you could point me to a good GCC user mailing list, that would be great. All I could find is GCC development mailing list, that has something to do with developing GCC itself rather than using GCC, which I don't think is very relevant to what I'm doing. Thanks in advance for any help. RDB -- Reuben D.
