# # config.mak.dist - sample musl-cross-make configuration # # Copy to config.mak and edit as desired. # # There is no default TARGET; you must select one here or on the make # command line. Some examples: # TARGET = i486-linux-musl # TARGET = x86_64-linux-musl # TARGET = arm-linux-musleabi # TARGET = arm-linux-musleabihf # TARGET = sh2eb-linux-muslfdpic # ... # By default, cross compilers are installed to ./output under the top-level # musl-cross-make directory and can later be moved wherever you want them. # To install directly to a specific location, set it here. Multiple targets # can safely be installed in the same location. Some examples: # OUTPUT = /opt/cross # OUTPUT = /usr/local # By default, latest supported release versions of musl and the toolchain # components are used. You can override those here, but the version selected # must be supported (under hashes/ and patches/) to work. For musl, you # can use "git-refname" (e.g. git-master) instead of a release. Setting a # blank version for gmp, mpc, mpfr and isl will suppress download and # in-tree build of these libraries and instead depend on pre-installed # libraries when available (isl is optional and not set by default). # Setting a blank version for linux will suppress installation of kernel # headers, which are not needed unless compiling programs that use them. # BINUTILS_VER = 2.25.1 # GCC_VER = 5.2.0 # MUSL_VER = git-master # GMP_VER = # MPC_VER = # MPFR_VER = # ISL_VER = # LINUX_VER = # Something like the following can be used to produce a static-linked # toolchain that's deployable to any system with matching arch, using # an existing musl-targeted cross compiler.
