## Linux GCC toolchain
|
|
|
|
The files in this directory define how we build our GCC cross-compiler that
|
|
targets Linux, using the musl libc.
|
|
|
|
### A note about `-rdynamic`
|
|
|
|
Do not pass `-rdynamic` to GCC when building an executable; it will cause the compiled executable to depend on a musl libc dynamic loader in `/lib` that probably doesn't exist, and defeats the point of static linking. The `-static` option overrides `-rdynamic`, so adding`-static` to the linker flags of a project using `-rdynamic` is one way to fix the issue.
|
|
|
|
CMake will pass `-rdynamic` unless you set [CMP0065](https://cmake.org/cmake/help/v3.8/policy/CMP0065.html) to new as shown below, or set your [CMake policy version](https://cmake.org/cmake/help/v3.8/command/cmake_policy.html) to 3.4 or later.

# Don't use -rdynamic since it causes Musl static linking to not work.
