http://sopc.et.ntust.edu.tw/pipermail/nios2-dev/2009-September/003066.htmlDear nios2 developers, Please note that I have rebuilt the gcc4 toolchain. The compiler is renamed to nios2-linux-gnu-gcc. Please pull toolchain-mmu/master and uClinux-dist/trunk to get updates. You may find patches and rebuild instruction in http://sopc.et.ntust.edu.tw/pub/gnutools/nios2gcc4/README. Cheers, Thomas Build nios2 gcc4 toolchain 0. you need gcc3 and makeinfo to build. install these packages, yum install compat-gcc-34 texinfo tetex* 1. get the source http://www.niosftp.com/pub/gnutools/wrs-linux-4.1-176-nios2-wrs-linux-gnu.src.tar.bz2 2. get the patches ftp://sopc.et.ntust.edu.tw/pub/gnutools/nios2gcc4 0001-binutils-fix-makeinfo-version-check-in-configure.patch 0001-gcc-fix-makeinfo-version-check-in-configure.patch 0001-gdb-fix-makeinfo-version-check-in-configure.patch 0001-kbuild-fix-C-libary-confusion-in-unifdef.c-due-to-g.patch build.sh REAME (this file) 3. untar the source tar jxf wrs-linux-4.1-176-nios2-wrs-linux-gnu.src.tar.bz2 4. in the wrs-linux-4.1-176-nios2-wrs-linux-gnu dir, there are source tarballs. extract them to build dir, /opt/nios2gcc4/src. cd wrs-linux-4.1-176-nios2-wrs-linux-gnu tar jxf binutils-4.1-176.tar.bz2 -C /opt/nios2gcc4/src tar jxf expat-4.1-176.tar.bz2 -C /opt/nios2gcc4/src tar jxf gcc-4.1-176.tar.bz2 -C /opt/nios2gcc4/src tar jxf gdb-4.1-176.tar.bz2 -C /opt/nios2gcc4/src tar jxf glibc-4.1-176.tar.bz2 -C /opt/nios2gcc4/src tar jxf glibc_localedef-4.1-176.tar.bz2 -C /opt/nios2gcc4/src tar jxf glibc_ports-4.1-176.tar.bz2 -C /opt/nios2gcc4/src tar jxf linux-4.1-176.tar.bz2 -C /opt/nios2gcc4/src 5. apply the patches cd /opt/nios2gcc4/src/binutils-2.17.50 patch -p1 < 0001-binutils-fix-makeinfo-version-check-in-configure.patch cd /opt/nios2gcc4/src/gcc-4.1 patch -p1 < 0001-gcc-fix-makeinfo-version-check-in-configure.patch cd /opt/nios2gcc4/src/gdb-wrs patch -p1 < 0001-gdb-fix-makeinfo-version-check-in-configure.patch cd /opt/nios2gcc4/src/linux-2.6.21-wrs-nios2 patch -p1 < 0001-kbuild-fix-C-libary-confusion-in-unifdef.c-due-to-g.patch 6. run the build script, you can change the build dir, /opt/nios2gcc4 and install dir /opt/nios2. sh build.sh 7. you will need mkimage of u-boot or install it from debian/ubuntu package uboot-mkinage. |
