IIRC when I investigated this with jscipione, a syscall trace showed that GCC was not even looking for String.h, and instead was just including string.h, as if the filesystem was case-insensitive. I didn't find any reason for why it would do that, and asking the GCC developers, they said that their builds handled this case just fine (they did not test with our cross tools though.) So I am rather stumped.

[jscipione]

I don't think that case-sensitivity is the issue here because I tried replacing every instance of #include <string.h> with #include <cstring> and it still ends up erroring out looking for missing symbols from string.h.

[waddlesplash]

Guess what ​<cstring> does?

#include <string.h>

So, that proves nothing.

I've run into this on Windows with case-sensitive NTFS with MSYS2, following hrev54127. I've confirmed that the two different String.h cannot be opened with different cases, but nonetheless, the error occurs.

Probably needs this patch: ​https://gitlab.uni.lu/ehamzic/openc2x_embedded/commit/81cc26c706b2bc8c8c1eb1a322e5c5157900836e

I added

#define HAVE_CASE_INSENSITIVE_FILE_SYSTEM 0

to the top of that file (as the lower defines are in #ifndef) and it did not help.

[waddlesplash]

Ah, there are actually two copies of that file: one in binutils and one in gcc. Maybe both need to be modified.

[waddlesplash]

Nope, that produced no difference, either. However, it looks like I have a system libiberty installed, which may be the source of this problem. I'll try removing it and see if that helps.

Fixed in btrev43156.
