I see cruft like "02.gtk-label" in directory names. I'm sure those can be renamed without problem. I also see that the macros used employ a leading "." on "local" (stack) variable names. I rather like this convention, as it matches the Nasm syntax for "local labels" (okay, pseudo-local labels). If *that's* the problem, it might be more work to undo. Name collisions, y'know. Your solution to it ought to be to give everything "full talking names". Might be an impractical pile of work, though. RosAsm's (non)treatment of underscores may be a problem, too... (you thought these changes from Nasm were an improvement... live with it...) I would have expected that a bigger "problem" to you would have been using gcc to link 'em. I have *no* idea what that "'pkg-config...'" bit on the command line does. Calling just "printf" (libc) or Xlib, I can get an executable out of ld, without going through gcc and linking in the "startup code". I don't know how "robust" that is, but it "seems to work". There may be a way to do it for gtk, too, but I haven't found it. Herbert has shown me a "better way" to get an ELF executable directly out of Nasm than has previously been done (AFAIK). Works if we *don't* call any dynamically linked libraries. It's apparently possible to do *that*, too. I haven't looked into it. http://www.mpeforth.com/arena/cwgtLinux.txt Don't be put off by the fact that it's "about" writing a Forth compiler. It shows how to get dynamically linked code out of Nasm without a linker. You may need to get "grounded" in the ELF format to understand it... as I said, I haven't tried it. It suggests that code that calls shared libraries *can* be produced by RosAsm/Wine... maybe... I hope you stick with Linux long enough to do something with it, but if it continues to be painful (I don't know if "three weeks" is too long or too short), don't keep beating your head against it. Life's too short! Best, Frank

Not all of these are installed by default, but they are there on the distribution media. If there are some specific packages which you are concerned about, I would be happy to check them for you. -- Chuck

I am looking at a Ubuntu/Debian package they call "libgtk2.0-dev" with a dozen or more dependencies that together become a 16MB download. I could get someone to d/l it for me, but if I'm gonna go to that much trouble, I'm thinking that I might as well get a spanking-new distro in the same basket. Nathan.

You are very talented at making errors on errors, sevag: 1) jmp 'libgtk-win32-2.0-0.gtk_init' where 'libgtk-win32-2.0-0' is the module name, in Frank Sources. 2) RosAsm doesn't touch anything in between quotes. So, "_" cannot be any problem. Betov. < http://rosasm.org > |
