Subject: Bug in CYGWIN's UUID library: GUID_NULL not found.
Date: Mon, 20 Feb 2023 16:48:50 +0100 [thread overview]
Message-ID: <CADt95757Eqp3z7rVD9s0nyjYKri52+G8LQ4R_afu7Hu7piafLg@mail.gmail.com> (raw)
Hello,
I think that there is a bug into the uuid library, the one to be used
with the W32API for the POSIX core.
Please have a look to the following tiny test code:
//====================
#include <windows.h>
#include <initguid.h>
#include <ks.h>
#include <stdio.h>
int main()
{
printf("GUID_NULL=\"%08X-%04X-%04X-%02X%02X-%02X%02X%02X%02X%02X%02X\"\n",
GUID_NULL.Data1,
GUID_NULL.Data2, GUID_NULL.Data3,
GUID_NULL.Data4[0], GUID_NULL.Data4[1],
GUID_NULL.Data4[2], GUID_NULL.Data4[3],
GUID_NULL.Data4[4], GUID_NULL.Data4[5],
GUID_NULL.Data4[6], GUID_NULL.Data4[7]
);
return 0;
}
//====================
Compiling it with x86_64-pc-cygwin or i686-pc-cygwin does not work:
$ gcc e.c -o e.exe -luuid
/usr/lib/gcc/x86_64-pc-cygwin/11/../../../../x86_64-pc-cygwin/bin/ld:
/tmp/ccyJK3d9.o:e.c:(.rdata$.refptr.GUID_NULL[.refptr.GUID_NULL]+0x0):
undefined reference to `GUID_NULL'
collect2: error: ld returned 1 exit status
But it works fine when using MinGW-w64 compilers:
$ x86_64-w64-mingw32-gcc e.c -o e.exe -luuid
$ ./e.exe
GUID_NULL="00000000-0000-0000-0000-000000000000"
I discovered this issue when making a new FluidSynth package for
CYGWIN for my repository of packages.
Can you confirm it?
Thank you very much for your time.
Sincerely,
Carlo Bramini.
