GCC: building cross compiler for ARM - pthread.h not found
Using Ubuntu 12.04 host, I followed closely this SO answer here ( Recipe for Compiling Binutils and GCC Together ) to build GCC and binutils in the same tree with all their dependencies.
Here is the config line I am doing inside my build directory:
../gcc-4.9.0/configure --target=arm-linux-gnueabi --prefix=/home/mint/cross-arm --disable-werror
The Makefile gets set up correctly and then I run:
sudo make -j8
I get into the compilation process for a while, and then eventually, here are the errors:

Am I missing a specific dependency that prevents this build?
PS I installed "build-essential" via apt-get before building.

The error indicates some problems with the C library.
To build a GCC compiler, you need to create binutils + a prebuilt C library beforehand.
In the case of a cross compiler, one of the possible paths is:
- Make sure you create binutils (cross compilation assembly) beforehand
- GCC Cross-Compilation: Add Tuning Option - No Headers. Now compile (see Creating targets in the link below).
- Compile your C library and reference it when compiling your program for the target
See some instructions for cross-compiling gcc here GCC Cross Compiling . Then "install" the appropriate C library (glibc / newlib).
Also, (if you don't already), it might be helpful to make sure the -prefix for bintutils and the gcc cross-compile assembly are the same location.
