Questions tagged [crosstool-ng]

Questions on using and developing crosstool-NG, a project to build compilers and tools from the gcc source and other related packages.

crosstool-NG is a collection of scripts for building tool chains (mainly gcc and support tools) and only tool chains. With crosstool-NG, you can precisely control how each component is configured and built, so you can produce a tool chain custom tailor for your system. crosstool-NG can build generic general purpose tool chains, to dedicated system specific tool chains. Configuration is guided ia a kbuild menu configuration interface. Both native and cross compilers are supported.

Support is continually evolving and includes langagues like Ada, C++, Java, Objective-C, Objective-C++, Go, etc. Various libraries are also supported, including newlib, uClibc, eglibc and glibc.

crosstool-NG is very simple in structure, consisting of shell scripts, gnu makefiles, source patches, and a kbuild system which directs the shell script. Additional documentation is available in crosstool-NG source directory in the docs sub-directory.

crosstool-NG is used by many open source projects, such as Ubuntu, Linaro, and buildroot.

crosstool-ng, directory structure, and sysroot

I have a working cross-compiler toolchain, thanks to crosstool-ng :) -- however, crosstool-ng is very sparsely documented, and I am brand new to cross-compiling. The specific host and target are not, I think, important in this context. I have some…

Why does toolchain name have separate OS and EABI fields.?

For eg. arm-unknown-linux-gnueabi Now, once the OS i.e Linux is fixed, the C Library will be fixed (GLibc) and hence the calling convention and ABI being followed will be fixed. What is the requirement of 4th field i.e. ABI separately? Can a…
