Subject: [PATCH] Fix DynamicLibrary to build with musl libc
|
||||
|
||||
stdin/out/err is part of the libc and not the kernel so we check for the
|
||||
specific libc that does the unexpected instead of linux.
|
||||
|
||||
This is needed for making it build with musl libc.

Subject: [PATCH] Fix build with musl libc
|

|

On musl libc the fopen64 and fopen are the same thing, but for
|
||||
compatibility they have a `#define fopen64 fopen`. Same applies for
|
||||
fseek64, fstat64, fstatvfs64, ftello64, lstat64, stat64 and tmpfile64.
