In particular, I'm trying to cross-compile Firefox 69.0.3 from x64 Ubuntu 19.10 to SPARC Solaris 11.4. The one-page document on how to do this (https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Cross-compiling_Mozilla) is somewhat limited. I'd appreciate any help I can get.
1. Is it mozconfig or .mozconfig? 2. Do I need to set CC and CXX? Do I set them in mozconfig or as shell env vars? 3. Do CC and CXX refer to the host C compiler, the target C compiler, or the C cross-compiler on the host? 4. Should I use gcc or clang? 5. How do I point the build to where my Rust cross-compiler on the Ubuntu machine is located? 6. Do I need to set FORCE_GCC? This is the mozconfig I'm using. Does this look right? # sh # Build configuration script # # See http://www.mozilla.org/build/unix.html for build instructions. # export CROSS_COMPILE=1 FORCE_GCC= # CC=clang CC=/usr/sparcv9-solaris/solaris/cross/bin/sparcv9-solaris2.11-gcc # CXX=g++ CXX=/usr/sparcv9-solaris/solaris/cross/bin/sparcv9-solaris2.11-g++ GCC_USE_GNU_LD= CARGO=/home/michele/rust/src/tools/cargo/src/bin/cargo RUST=/usr/local/bin/rustc SYSROOT=/usr/sparcv9-solaris/solaris/cross/sysroot PKG_CONFIG_PATH=/usr/sparcv9-solaris/solaris/cross/sysroot/usr/lib/pkgconfig export BINDGEN_CFLAGS="--sysroot=/usr/sparcv9-solaris/solaris/cross/sysroot" ac_add_options --prefix=/usr/sparcv9-solaris/solaris/cross/sysroot/usr/lib ac_add_options --target=sparcv9-sun-solaris # Options for 'configure' (same as command-line options). # all are listed so that one can manually tweak this config file. mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/obj-release mk_add_options SYSROOT=/usr/sparcv9-solaris/solaris/cross/sysroot ac_add_options --enable-application=browser # ac_add_options --enable-tests ac_add_options --disable-jemalloc # ac_add_options --enable-dtrace ac_add_options --disable-debug # ac_add_options --enable-optimize ac_add_options --disable-ipc ac_add_options --disable-crashreporter ac_add_options --disable-verify-mar _______________________________________________ dev-builds mailing list dev-builds@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-builds
