Hi,

Trying to build this simple program:

#include <string>

int main()
{
std::string s("Hello world");
}

with:
  gpp  --std=c++17 -c SIMPLE.CPP

results in error:
  In file included from c:/djgpp/include/cxx/10/string:55,
  from SIMPLE.CPP:1:
c:/djgpp/include/cxx/10/bits/basic_string.h:48:11: fatal error:
string_view: No such file or directory (ENOENT)
  48 | # include <string_view>
       |
compilation terminated.

However with:
  gpp -c SIMPLE.CPP

It compiles fine.

The file DJGPP/INCLUDE/CXX/10/STRING.VIE is there.

I have installed the following files:
djdev205.zip
bnu2351b.zip
gcc1030b.zip
gpp1030b.zip
mak43b.zip

Running in a DOSBOX under Ubuntu Linux.

Any idea?
josue
