I use 'all-gcc', though 'bootstrap' might have been changed by configure/make to 'all-gcc' since it was a cross build. Also, make sure your path is set so that GCC can find the linker and assembler that it needs. > I'm not sure where the libc.so message is coming from. One thing to note is that the mips64-linux target is a multi-lib target that can build o32, n32, and n64 objects (the three ABI's that MIPS supports). If you only care about one ABI you might try adding'--disable-multilibs' along with '--with-abi=n32' or '--with-abi=n64' depending on which ABI you want to see if that helps. I have some build instructions and a script at https://dmz-portal.mips.com/wiki/GCC_Build_Instructions That should be visible to you and you can try that build method if you want. Steve Ellcey
