Definitively I have mate a tar.bz2 with gcc-3.4.6 modified to mak it able t= o=20 build properly on top of binutils-2.17 (from sh7203-uclinux-1.4 of MPC Data) and on uClibc-0.9.27-sh2 form same source. The only problem stiill present is I have to modify the files=20 build/stage/gcc/sh-linux/pic/libiberty/Mikefole to add ac CC line -m4=20 and The only problem stiill present is I have to modify the files=20 build/stage/gcc/sh-linux/pic/mb/libiberty/Mikefole to add ac CC line -m4 otherwise I get an assembler error. But for my purpouse the toolchain work; I have benn able to compile a very= =20 sample application based on SDL and GUIlib (you can check on libsdl.org.) GUIlib a a c++ framework for building a graphical application. The app is 540 kbyte, so also the size is good for me. I think havign c++ working on such a target is a very usefull think. Let me know if you like to download the tar.bz2 from my server. If yes I'll open a tempiorary account and I send you all the necessary info= s.
