## Environment Variables with Cross Builds | ||
|
||
Previously in Meson, variables like `CC` effected both the host and build | ||
platforms for native builds, but the just the build platform for cross builds. | ||
Now `CC_FOR_BUILD` is used for the build platform in cross builds. | ||
|
||
This old behavior is inconsistent with the way Autotools works, which | ||
undermines the purpose of distro-integration that is the only reason | ||
environment variables are supported at all in Meson. The new behavior is not | ||
quite the same, but doesn't conflict: meson doesn't always repond to an | ||
environment when Autoconf would, but when it does it interprets it as Autotools | ||
would. |
