Subject: [PATCH 11/30] musl: Fix syscall wrappers
|
|
|
|
musl defines p{read,write}64 to their non-suffixed equivalents to avoid
|
|
duplication in its syscall wrappers. This breaks macro expansion here,
|
|
leading to errors such as:
|
|
|
|
In function size_t sys_pread64(int, void*, size_t, off_t):
|
|
error: '__NR_pread' was not declared in this scope
|
|
|
|
The fix here is to undefine the p{read,write}64 macros, so the syscall
|
|
expands to (e.g.) __NR_pread64 instead.
