--- Comment #7 from Jonny Grant <jg at jguk dot org> ---
Here is anotehr example.
I expected <string.h> to be suggested, as that contains exact match strerror()
Current G++ trunk output
<source>: In function 'int main()':
<source>:14:33: error: 'errno' was not declared in this scope
14 | printf("%s\n", strerror(errno));
| ^~~~~
<source>:4:1: note: 'errno' is defined in header '<cerrno>'; did you forget to
'#include <cerrno>'?
3 | #include <stdio.h>
+++ |+#include <cerrno>
4 | int main()
<source>:14:24: error: 'strerror' was not declared in this scope; did you mean
'perror'?
14 | printf("%s\n", strerror(errno));
| ^~~~~~~~
| perror
Compiler returned: 1
example
// gcc -o glibc_realpath glibc_realpath.c
#include <stdlib.h>
#include <stdio.h>
int main()
{
const char * path = "/usr/bin/../include/myheader.h";
//errno = 0;
char * result = realpath(path, NULL);
printf("result: [%s]\n", result);
if(NULL == result)
{
printf("%s\n", strerror(errno));
}
return 0;
}
