@ -12,11 +12,15 @@ The toolchain generated by Buildroot is located by default in
+output/host/bin/+ to your PATH environment variable and then to
use +ARCH-linux-gcc+, +ARCH-linux-objdump+, +ARCH-linux-ld+, etc.
It is possible to relocate the toolchain - but then +--sysroot+ must
be passed every time the compiler is called to tell where the
libraries and header files are.
It is possible to relocate the toolchain, this allows to distribute
the toolchain to other developers to build applications for your
target. To achieve this:
* run +make sdk+, which prepares the toolchain to be relocatable;
* tarball the contents of the +output/host+ directory;
* distribute the resulting tarball.
Once the toolchain is installed to the new location, the user must run
the +relocate-sdk.sh+ script to make sure all paths are updated with
the new location.
It is also possible to generate the Buildroot toolchain in a directory
other than +output/host+ by using the +Build options -> Host dir+
option. This could be useful if the toolchain must be shared with
other users.
