I finally got the library to compile successfully using MSYS1. It turns out
libtool doesn't like spaces in the toolchain's directory. by default,
MinGW-w64 installs to C:\Program FIles or C:\Program Files (x86). When I was
trying to compile libtool, it was kind enough to tell me (and it was correct).
Anyway, I wanted to say thank you for the code. I don't know if this is a
bug with the code that you shown or if it's a bug with the library. However,
if no serial ports are hooked up to the system, the code below crashes the
program.
I wonder if there's a way to prevent that. It crashes the program regardless
of whether I'm using the 32-bit version of the library or the 64-bit. I
haven't tried it in Linux yet though, just Windows 7. Any suggestions?

No problem, this is the correct one, there's no specific one for
libserialport.

Here's a quick example to get you started, it'll list all ports it can
detect. Tested on Linux, but libserialport also works fine on Windows.
You need MinGW-w64 (the "old" MinGW will not work).
#include <stdio.h>
#include <libserialport.h>
int main(void)
{
int i;
struct sp_port **ports;
sp_list_ports(&ports);
for (i = 0; ports[i]; i++)
printf("Found port: '%s'.\n", sp_get_port_name(ports[i]));
sp_free_port_list(ports);
}
Hope that helps, Uwe.
