Subject: [PATCH] emulate clang 'sysroot + /include' logic
|
|
|
|

|
Clang provided by nix patches out logic that appends 'sysroot + /include'
|
|
to the include path as well as automatic inclusion of libcxx includes (/include/c++/v1).
|
|
The patch below adds that logic back by introducing cflags emulating this behavior to emcc
|
|
invocations directly.
|
|
|
|
Important note: with non-nix clang, sysroot/include dir ends up being the last
|
|
in the include search order, right after the resource root.
|
|
Hence usage of -idirafter. Clang also documents an -isystem-after flag
|
|
but it doesn't appear to work
