• But if you reverse the order, it works.

#define csp_without_prefix

#include <unistd.h>
#include <libcsp/csp.h>

How can solve this problem? Am i use "csp_async" and "csp_sync" not "sync" and "async".

Thankyou for reading this issue

Please make sure that it meets

• GCC >= 8.0
• Architecture = Linux x86_64

Here's my environment

• GCC : 13.1.1
• Architecture: Linux arch 6.3.8-arch1-1 x86_64

I have tested it with GCC 8/9/10, not sure whether it's caused by the gcc version. You can try it with gcc8 to test it.

I think you need to consider the order of "include".
Not like this

#include <libcsp/csp.h>
#include <unistd.h>

like this

#include <unistd.h>
#include <libcsp/csp.h>
