# 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, and to get lld. |
|
# 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. |
|
|
|
# Run this in the demumble root directory while on the "release" branch. |
|
# It'll create subcirectories "buildlinux", "buildmac", "buildwin" to build |
|
# for each platforms, and then puts the final built products in |
|
# demumble-{linux,mac,win}.zip. |
|
|
|
# Runs demumble_test.py on mac at the end, but best make sure it passes on |
|
# on all 3 platforms before running this script. |
|
|
|
# https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/CrossCompiling has |
|
# some documentation on cross builds with cmake. |
