From dfce4a7b33464b39f7677cfb4d093f19c566e756 Mon Sep 17 00:00:00 2001 From: Jon Date: Mon, 4 Jun 2012 20:11:55 -0400 Subject: Add Ubuntu -> Linux-on-ARM CMake toolchain files Add separate sample CMake toolchain files targeting Linux running on ARM, with and without hardware floating point support. Samples use the `gcc-arm-linux-gnueabihf` and `gcc-arm-linux-gnueabi` cross toolchains from the standard Ubuntu package repositories. --- cmake/Toolchain-Ubuntu-gnueabi.cmake.sample | 29 +++++++++++++++++++++++++++ cmake/Toolchain-Ubuntu-gnueabihf.cmake.sample | 29 +++++++++++++++++++++++++++ 2 files changed, 58 insertions(+) create mode 100644 cmake/Toolchain-Ubuntu-gnueabi.cmake.sample create mode 100644 cmake/Toolchain-Ubuntu-gnueabihf.cmake.sample (limited to 'cmake') diff --git a/cmake/Toolchain-Ubuntu-gnueabi.cmake.sample b/cmake/Toolchain-Ubuntu-gnueabi.cmake.sample new file mode 100644 index 000000000..bf29a5cad --- /dev/null +++ b/cmake/Toolchain-Ubuntu-gnueabi.cmake.sample @@ -0,0 +1,29 @@ +# Sample toolchain file for building for ARM from an Ubuntu Linux system. +# +# Typical usage: +# 1) install cross compiler: `sudo apt-get install gcc-arm-linux-gnueabi` +# 2) cp cmake/Toolchain-Ubuntu-gnueabi.cmake.sample ~/Toolchain-Ubuntu-gnueabi.cmake +# 3) tweak toolchain values as needed +# 4) cd build +# 5) cmake -DCMAKE_TOOLCHAIN_FILE=~/Toolchain-Ubuntu-gnueabi.cmake .. + +# name of the target OS on which the built artifacts will run and the +# toolchain prefix. if target is an embedded system without an OS, set +# CMAKE_SYSTEM_NAME to `Generic` +set(CMAKE_SYSTEM_NAME Linux) +set(TOOLCHAIN_PREFIX arm-linux-gnueabi) + +# cross compilers to use for C +set(CMAKE_C_COMPILER ${TOOLCHAIN_PREFIX}-gcc) + +# target environment on the build host system +# set 1st to dir with the cross compiler's C/C++ headers/libs +# set 2nd to dir containing personal cross development headers/libs +set(CMAKE_FIND_ROOT_PATH /usr/${TOOLCHAIN_PREFIX} ~/crossdev/eabi) + +# modify default behavior of FIND_XXX() commands to +# search for headers/libs in the target environment and +# search for programs in the build host environment +set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) +set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) +set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY) diff --git a/cmake/Toolchain-Ubuntu-gnueabihf.cmake.sample b/cmake/Toolchain-Ubuntu-gnueabihf.cmake.sample new file mode 100644 index 000000000..2d7f2769c --- /dev/null +++ b/cmake/Toolchain-Ubuntu-gnueabihf.cmake.sample @@ -0,0 +1,29 @@ +# Sample toolchain file for building for ARM (w/hw float support) from an Ubuntu Linux system. +# +# Typical usage: +# 1) install cross compiler: `sudo apt-get install gcc-arm-linux-gnueabihf` +# 2) cp cmake/Toolchain-Ubuntu-gnueabihf.cmake.sample ~/Toolchain-Ubuntu-gnueabihf.cmake +# 3) tweak toolchain values as needed +# 4) cd build +# 5) cmake -DCMAKE_TOOLCHAIN_FILE=~/Toolchain-Ubuntu-gnueabihf.cmake .. + +# name of the target OS on which the built artifacts will run and the +# toolchain prefix. if target is an embedded system without an OS, set +# CMAKE_SYSTEM_NAME to `Generic` +set(CMAKE_SYSTEM_NAME Linux) +set(TOOLCHAIN_PREFIX arm-linux-gnueabihf) + +# cross compilers to use for C +set(CMAKE_C_COMPILER ${TOOLCHAIN_PREFIX}-gcc) + +# target environment on the build host system +# set 1st to dir with the cross compiler's C/C++ headers/libs +# set 2nd to dir containing personal cross development headers/libs +set(CMAKE_FIND_ROOT_PATH /usr/${TOOLCHAIN_PREFIX} ~/crossdev/eabihf) + +# modify default behavior of FIND_XXX() commands to +# search for headers/libs in the target environment and +# search for programs in the build host environment +set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) +set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) +set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY) -- cgit v1.2.3 From f75c277058341a5432cb3de5beda16cb78faafc6 Mon Sep 17 00:00:00 2001 From: Daniel Bovensiepen Date: Fri, 8 Jun 2012 22:54:42 +0800 Subject: Add first sample for MIPS cross compile --- cmake/Toolchain-Linux-openwrt-mips.cmake.sample | 10 ++++++++++ 1 file changed, 10 insertions(+) create mode 100644 cmake/Toolchain-Linux-openwrt-mips.cmake.sample (limited to 'cmake') diff --git a/cmake/Toolchain-Linux-openwrt-mips.cmake.sample b/cmake/Toolchain-Linux-openwrt-mips.cmake.sample new file mode 100644 index 000000000..73ec9874b --- /dev/null +++ b/cmake/Toolchain-Linux-openwrt-mips.cmake.sample @@ -0,0 +1,10 @@ +# Toolchain file for building with OpenWRT Toolchain for MIPS. +# This is a preliminary version for mips outside of the buildroot-ng. +# The next version should be target independent. +# Further improvements: +# -
