cross-toolchains's Introduction

cross-toolchains

Script for build cross-toolchain for ARMEL, ARMBE, MIPSEL, MIPS, PowerPC, i686

Docker enviroment variables

For use that variables, set them with --build-arg

TARGET - Set custom target for toolchain
CFLAGS_FOR_TARGET - Set CFLAGS for build taret binaries
CXXFLAGS_FOR_TARGET - Set CXXFLAGS for build taret binaries
GCC_PARAMS - Set custom flags for build target GCC
GLIBC_EX_FLAGS - Set custom flags for build target glibc
SSL_MARCH - Set custom -march for build target openssl

For example:

docker build -t mipsel-linux-gnu \
    --build-arg ARCH=mipsel \
    --build-arg GCC_PARAMS="--with-float=soft" \
    .

Execute post scripts

If you need to perform some additional actions after the assembly of the toolchain is complete, add the following file:

docker build -t mipsel-linux-gnu \
    -v /path/to/your_script:/etc/post_toolchain_script.sh \
    --build-arg ARCH=mipsel .

Howto build the docker images

MIPS Little Endian x32

docker build --build-arg ARCH=mipsel -t mipsel-linux-gnu .

MIPS Big Endian x32

docker build --build-arg ARCH=mips -t mips-linux-gnu .

ARM Little Endian x32

docker build --build-arg ARCH=armel -t armel-linux-gnu .

ARM Big Endian x32

docker build --build-arg ARCH=armbe -t armbe-linux-gnu .

i686 Little Endian

docker build --build-arg ARCH=i686 -t i686-linux-gnu .

PowerPC Big Endian x32

docker build --build-arg ARCH=powerpc -t powerpc-linux-gnu .

cross-toolchains's Issues

Compilers not available

It appears to be using distcc but is not available when run:

$ docker run -td -p 3623:3623 powerpc-linux-gnu
7bd4dbc610388d8cb7af23373008e5b6e0e8d3cc211a4eaec68e3b0a2e152ab2

$ docker container inspect -f '{{ .NetworkSettings.IPAddress }}' youthful_cori 
172.17.0.3

$ export DISTCC_HOSTS=172.17.0.3

$ distcc powerpc-linux-gnu-gcc hey.c 
distcc[1117400] (dcc_execvp) ERROR: failed to exec powerpc-linux-gnu-gcc: No such file or directory
distcc[1117399] ERROR: compile hey.c on localhost failed with exit code 110

When running tools.sh for build gdb with postfix 'a', e.g. gdb-7.0a.tar.gz or gdb-6.8a.tar.gz, bug occurs.
In tar.gz archive dir named without 'a' postfix, but script trying change directory to version+a suffix and fail. Also script create build directory with 'a' postfix, but sources in tar.gz archive contains in folder without 'a' postfix.
