Gidday all, I've built a simple toolchain for Xscale development on a custom board (no OS). binutils build: ../binutils-20021117-1/configure --host=i686-pc-cygwin --target=xscale-elf --prefix=/xscale --norecursion gcc build: ../gcc-3.2-3/configure --with-gcc-version-trigger=/usr/src/gcc-3.2-3/gcc/version.c --host=i686-pc-cygwin --enable-languages=c,c++ --with-included-gettext --enable-shared --enable-threads --target=xscale-elf --with-newlib --prefix=/xscale -v --norecursion newlib build: ../newlib-1.10.0/configure --host=i686-pc-cygwin --target=xscale-elf --prefix=/xscale -v --norecursion These commands created a simple xscale toolchain, and when I compile a program all is well. The problem is I have not provided my own sbrk(), open(), etc functions! The program itself works on the target, but I need to provide a custom sbrk() implementation to fix a dynamic memory allocation issue with our hardware. I have added sbrk(), open(), getpid(), etc functions into a platform layer, and they are compiled in, but the newlib malloc() is not calling my sbrk() implementation.. What am I forgetting here???? Thankyou for any assistance. Cheers, Ben ------ Want more information? See the CrossGCC FAQ, http://www.objsw.com/CrossGCC/ Want to unsubscribe? Send a note to crossgcc-unsubscribe@sources.redhat.com
