It depends on the operating system you are using as well as the linker. If you are using the GNU linker, you can do what you want by using linker scripts, but these are very arcane..... I have worked on platforms where it was impossible to write self modifying code in any fashion, and on many other systems where you had to go through various hoops to make sure all of the caches are flushed properly (the trampoline code within the compiler generates self modifying code). -----Original Message----- From: gcc-help-owner@xxxxxxxxxxx [mailto:gcc-help-owner@xxxxxxxxxxx] On Behalf Of William Sent: Monday, March 13, 2006 10:59 PM To: gcc-help@xxxxxxxxxxx Subject: Write enable .text section Hi, I'm trying to implement some self-modifying code. Usually I use Visual C++ so I'm not too familiar with the linker that gcc uses. I can't figure out how to enable write for the .text section so I don't get an access violation when the SMC runs. Anyone can help? Thanks! __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
