# Q: How to turn on static PIE support?

There's a [patch] by Harald Hoyer. It's been tested and is in use in the [Fedora package].

To use the musl-gcc wrapper:

```sh
CC="musl-gcc -static-pie" ./configure --prefix=$HOME/musl && make
```

`-static-pie` only affects linking options (`-static -pie --no-dynamic-linker -z text`), not compile options (`-fPIE`). As the default toolchain config isn't visible to the spec file logic, building a musl-based cross-toolchain is [recommended for non-basic use].
