Building NPTL-capable toolchains Home / Writings This page describes a script I've cobbled together from various sources, that allows me to build a cross-compiling toolchain (binutils, gcc, glibc) that are NPTL (Native Posix Threading Library) capable, running on Fedora Core 3.

This is mostly a staging area until I take a look at crosstool and see how this can be integrate there. Hopefully, I'll actually get around to doing that! Some caveats: I've only run this on Fedora Core 3. It should work elsewhere, but it's not tested.I've used hard-coded binutils/gcc/glibc versions. It certainly won't work out of the box for other combinations, because it only has patches for this specific combination. crosstool contains a repository of useful patches. Hopefully, I'll get around to looking at how to integrate this into crosstool one day. The resultant PPC toolchain has been used to build simple pthreads test applications, and these do run on real hardware (a MontaVista 3.1 system, where I replaced the provided glibc with the one built here, and ran the test app). The x86 toolchain has not been tested at all. To use this, create a working directory (same ~/nptltool). Put all the scripts from the list below in a sub-directory of that directory named "downloads". Then, make sure you have downloaded the source to binutils, glibc, gcc & the kernel into downloads. Finally, read and then run nptl_build.sh, and wait.
