something like this :

MRuby::CrossBuild.new('32bit') do |conf|
  toolchain :"arm-linux-gcc"
  conf.cc.flags << "-m32"
  conf.linker.flags << "-m32"
  conf.build_mrbtest_lib_only
  conf.gem 'examples/mrbgems/c_and_ruby_extension_example'
  conf.test_runner.command = 'env'
end

my cross build tools is :

arm-linux-addr2line     arm-linux-cpp           arm-linux-gcov          arm-linux-populate
arm-linux-ar            arm-linux-ct-ng.config  arm-linux-gprof         arm-linux-ranlib
arm-linux-as            arm-linux-g++           arm-linux-ld            arm-linux-readelf
arm-linux-c++           arm-linux-gcc           arm-linux-nm            arm-linux-size

arm-linux-gccbug        arm-linux-objdump       arm-linux-strip

all in there:

The toolchain you try to use doesn't exist. Have a look here: https://github.com/mruby/mruby/tree/master/tasks/toolchains

You have to create a toolchain file which describes the compiler tool names.

so , I have create a toolchains ,
and edit arm.rake for "arm-linux-gcc" .
but did't konw how to do next :


cd tasks/toolchains
cp gcc.rake arm.rake


MRuby::CrossBuild.new('32bit') do |conf|
  toolchain :arm
  ...
end

did you adapted the content of the toolchain? I.e. changing the identifier from :gnu to :arm and also changing the compiler tool names?

Your toolchain should also contain an archiver command for arm (ar). Can you configure the command:
conf.archiver.command
to use it? Otherwise it will use the local ar command which I don't know if it is compatible with the arm linker.

when add " conf.archiver.command " into MRuby::Toolchain.new(:arm) :

conf.archiver do |ar|
  ar.command = 'arm-lnux-ar'
end

whether need define each command :

arm-linux-addr2line     arm-linux-cpp           arm-linux-gcov          arm-linux-populate
arm-linux-ar            arm-linux-ct-ng.config  arm-linux-gprof         arm-linux-ranlib
arm-linux-as            arm-linux-g++           arm-linux-ld            arm-linux-readelf
arm-linux-c++           arm-linux-gcc           arm-linux-nm            arm-linux-size
arm-linux-cc           arm-linux-objcopy         arm-linux-strings        arm-linux-c++filt       
arm-linux-gccbug        arm-linux-objdump       arm-linux-strip

when I configure a cpp source , just need run this :
./configure --host=arm-linux && make -j4

so , what is the easiest way to define these commands ?
