cross compiling for arm

[dstorey]

Hi

I'm trying to cross compile the linux code for a Technologic TS-7250 arm board. Has anyone done this or tried something similar? I tried creating a special cmake file ts72xx.cmake with the following:


SET(CMAKE_SYSTEM_NAME Linux)

SET(CMAKE_SYSTEM_VERSION 1)

# specify the cross compiler
SET(CMAKE_C_COMPILER /usr/local/ts72xx/arm/bin/arm-oe-linux-gnueabi-gcc)
SET(CMAKE_CXX_COMPILER /usr/local/ts72xx/arm/bin/arm-oe-linux-gnueabi-g++)

# where is the target environment
SET(CMAKE_FIND_ROOT_PATH /usr/local/ts72xx/arm)

# search for programs in the build host directories
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
# for libraries and headers in the target directories
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

[ends]

then from the directory where I unzipped the source, I ran

cd build
cmake -DCMAKE_TOOLCHAIN_FILE=./ts72xx.cmake ..
make && make install

but it doesn't result in a cross-compile, just a standard compile.

Any ideas?

thanks Dominic

If you set VERBOSE_MAKEFILE till YES (easiest done with ccmake) you can see which tools cmake calls.
