| # Builds demumble for Mac, Linux, Windows. Must run on a Mac. |
| # Needs a chromium checkout at ~/src/chrome/src that was synced with |
| # target_os=['win'] to get the Windows toolchain. You must run |
| # `build/linux/sysroot_scripts/install-sysroot.py --arch amd64` once to |
| # get the linux toolchain. |
| |
| # Also needs a GN build of llvm at ~/src/llvm-project/out/gn for llvm-strip |
| # for stripping the Linux binary. |
| |
| # Doesn't run tests, so make sure to run `./demumble_test.py` on all 3 platforms |
| # before running this script. |
| |
| # After this script finishes successfully, the cwd will contain |
| # demumble-mac.zip, demumble-linux.zip, demumble-windows.zip which each contain |
| # a demumble binary built for that OS, ready for releasing (assuming the script |
| # was run on the release branch). |
| |
| # https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/CrossCompiling has |
| # some documentation on cross builds with cmake. |
