You can use gcc-core from http://ftp.gnu.org/gnu/gcc/gcc-4.5.4/
Indeed you need several packages/dependencies in order to compile gcc configure script will generally tell you what to install (like what you pasted). To compile a lm32-elf toolchain you can have a look there: http://milkymist.org/wiki/index.php?title=Compiling_a_lightweight_Mico32_toolchain Just use gcc 4.5.4 instead of 4.5.3 and use binutils 2.24 2014/1/10 Salman Sheikh <salmanishe...@gmail.com> > Now in that misoc/README you referenced, it mentioned installing gcc...I > am attempting to do so but I don't find a gcc-core and gcc-g++ but just one > large (105MB) gcc file.
