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 .
