Re: [Simulavr-devel] SimulAVR Compilation Problem

[Mattias Wildeman]

Well, i did the lazy thing and worked past the inet_pton in
mysocket.cpp replacing it with "adress->sin_addr.s_addr =
htons(0x7f000001);".

After that it compiles fine, but i've run into a really weird problem.
If i didn't know better, i would suspect
there was a compiler bug, but it is probably related to some sort of
c++ overloading.

The problem occurs with "getopt_long" in main.c. After fetching the
"-d atmega8", the code enters the " case 'd' " switch and tries to
access "optarg". Weirdly enough, it is a null pointer! If i use GDB to
check it, it displays the correct value though.

I'm not very familiar with c++, c is what i typically use for coding.
Is there any c++ version of getopt that could be used instead? Anyone
got any idea why optarg ends up with a null pointer? (Note: This is on
Cygwin on Windows).

BR,
Mattias
