Hello, I was using a Microtec tool chain to generate an executable binary with relocatable code (pc-relative) and data from a fixed address (Absolute data). Today, this tool chain does not work on Windows 7 64 bits. The idea is to replace Microtec tool chain for 68000 with the GNU tool chain (GCC 4.8.0). But I can not find the same options on the gcc compiler: Microtec compiler "MCC68K" with: "-Mcp": Directs the compiler to use PC-relative addressing for all code references. "-Mda": Directs the compiler to use absolute addressing for all data references. Gcc (m68k-elf-gcc) with: -mpcrel Unable to build with gcc relocatable code with no relocatable data as the Microtec compiler. With "-mpcrel", all is relocatable (code and data). do you have an idea? Sorry for my bad English. Thanks.
