That's why it fails with "File format not recognized". Hopefully, it failed, because I asked you to link with --traditional-format in order to have the debugging symbols in MonST ! Unfortunatly, MonST was unable to load the symbols because the symbol table is huge :-( due to the usage of iostream. Nevertheless, I'm used to walk into the startup code 8-) The problem is that you use gcc-4.2.2-mint-20080107 (especially libgcc.a) with binutils < binutils-2.18-mint-20080106 (especially ld) You fall into the CONSTRUCTORS problem. I saw in your program that a single "Hello, World !" using cout produces 6 global contructors in the final executable (probably produced inside libstdc++). Shame on me, I didn't check that. I thunk that the usage of global constructors was not usual, I was wrong. So the new rule is: When you make C++ programs with gcc >= 4.2.2-mint-20080107, you MUST use binutils >= 2.18-mint-20080106 If you don't do so, your program will crash at startup. I definitively should display the patch version with --version ! You can make a quick test by using my cross-compiled binutils for MiNT: http://vincent.riviere.free.fr/soft/m68k-atari-mint/archives/unsupported/binutils-2.18-mint-20080119-bin-mint-20080119.tar.bz2 For the test purpose, you might only use the ld program from that archive. Your C++ programs will work immediately (after relink !) Please give me feedback ! -- Vincent Rivière
