# Overview
|
|
|
|
This directory contains files that make it possible for Linux
|
|
distributions to build Chromium using system toolchain.
|
|
|
|
For more info on established way such builds are configured,
|
|
please read the following:

Why do distros want CFLAGS, LDFLAGS, etc? Please read the following
|
|
for some examples. This is not an exhaustive list.

# Usage
|
|
|
|
Add the following to GN args:
|
|
|
|
```
|
|
custom_toolchain="//build/toolchain/linux/unbundle:default"
|
|
host_toolchain="//build/toolchain/linux/unbundle:default"
|
|
```
|
|
|
|
See [more docs on GN](https://gn.googlesource.com/gn/+/main/docs/quick_start.md).
|
|
|
|
To cross-compile (not fully tested), add the following:
|
|
|
|
```
|
|
host_toolchain="//build/toolchain/linux/unbundle:host"
|
|
v8_snapshot_toolchain="//build/toolchain/linux/unbundle:host"
|
|
```
|
|
|
|
Note: when cross-compiling for a 32-bit target, a matching 32-bit toolchain
|
|
may be needed.
