Hi All,

I'm trying to create a toolchain for x86_64 linux on a 64 bit Mac running OSX 10.9.5 and using crosstool-ng-1.22.0. I have tried building using a number of the samples ("x86_64-w64-mingw32,x86_64-pc-linux-gnu" and "x86_64-unknown-linux-gnu") but I am running into build errors, as shown below. I am not building the gold linker, nor am I attempting to link statically, and I am building on a case-sensitive file system. The build.log and config are shown after the error listing.

It looks as though the build environment is perhaps looking for OSX header files (within /usr/include) when installing/building the kernel headers, rather than Linux ones, but I don't know what to do to fix this.

Can anyone please offer advice for what I need to do to build successfully?  This has also been posted on stack overflow (http://stackoverflow.com/questions/39140110/crosstools-ng-compiling-toolchain-for-x86-64-linux-on-osx-error-when-installi), so feel free to answer there if you'd prefer.

Many thanks,

John
