As far as I can see:

Code: Select all

// IWYU pragma: begin_keep
#if defined(WEBRTC_LINUX)
#include <linux/prctl.h>
#include <sys/prctl.h>
// ...
#endif

Looks like a portability bug, probably upstream: <linux/prctl.h> from the kernel headers package and <sys/prctl.h> from the libc can't end up getting both included in the same source file when using musl; musl's version of the libc header defines struct prctl_mm_map (in a way that is compatible with what the Linux system call expects, obviously), while GNU libc's version contains an #include <linux/prctl.h> directive instead, and gets the definition of the structure type from the kernel header. So with musl, including both headers creates a double definition.

until librewolf maintainers update librewolf (on the overlay and just in general) you can patch out the <linux/prctl.h> include with a user patch. i encountered this too and this was my solution until update fixed it
