I thought I'd play with libunistring so for the first
time I downloaded the following packages:
$ cygcheck -c libunistring-devel libunistring-doc libunistring2
Cygwin Package Information
Package Version Status
libunistring-devel 0.9.5-1 OK
libunistring-doc 0.9.5-1 OK
libunistring2 0.9.5-1 OK
$
Then wrote what I thought would be a trivial first program.
#include <uniname.h>
#include <stdio.h>
int main (void)
{
char buffer[UNINAME_MAX] = "(undefined)";
ucs4_t uc = 0x20AC; /* euro symbol */
unicode_character_name (uc, buffer);
puts (buffer);
return 0;
}
It compiles fine, but I don't know how to get it to link.
$ gcc -lunistring unicode_character_name.c
/tmp/ccaJ19ki.o:unicode_character_name.c:(.text+0x57): undefined reference to `unicode_character_name'
/tmp/ccaJ19ki.o:unicode_character_name.c:(.text+0x57): relocation truncated to fit: R_X86_64_PC32 against undefined symbol `unicode_character_name'
collect2: error: ld returned 1 exit status
$
The only relevant library file that I found in the installation
(https://cygwin.com/packages/x86_64/libunistring-devel/libunistring-devel-0.9.5-1)
is usr/lib/libunistring.dll.a, the "dll" part of which seems odd to me.
Specifying -lunistring.dll produced the same error message.
Ideas?

The order is important on Cygwin, try:
gcc -o unicode_character_name unicode_character_name.c -lunistring
> libunistring.dll.a, the "dll" part of which seems odd to me
That's the way it works, a stub library (needed by the linker) with the
contents of the (real) dynamic library (i.e. there is a corresponding
lib<name>.dll).

Try
$ gcc unicode_character_name.c -lunistring

try in this way:
$ gcc unicode_character_name.c -lunistring
order matters on Windows
