Hi Mirek,

I'll give it another try, now.
I bought an eeePC and installed OpenBSD 4.4 on it.
Default compiler is GCC 3.3.5.
I downloaded Upp 2008.1 and adjusted sources and Makefile to compile fine, but in static, NOGTK, debug mode.
Then when I want to start TheIDE, I get an segfault in VCont.h asserting about Container size.
After debugging, I have found that the error occurs at line 437 in Draw/Image.cpp.
Here is part of the debug session:

437							m.image = cached[i];
(gdb) p cached
$15 = {<Upp::MoveableAndDeepCopyOption<Upp::Vector<Upp::Image>, Upp::EmptyClass>> = {<Upp::Moveable<Upp::Vector<Upp::Image>, Upp::DeepCopyOption<Upp::Vector<Upp::Image>, Upp::EmptyClass> >> = {<Upp::DeepCopyOption<Upp::Vector<Upp::Image>, Upp::EmptyClass>> = {<Upp::EmptyClass> = {<No data fields>}, <No data fields>}, <No data fields>}, <No data fields>}, vector = 0x0, items = 0, alloc = 0}
(gdb) p i
$16 = 0
(gdb) bt
#0  Upp::Iml::Get (this=0x3c3f9c60, i=0) at uppsrc/Draw/Image.cpp:437

As you can see cached is empty, that means assignment at line 432 gave an empty image vector.

I hope you'll find it worth to get Upp also running on OpenBSD, even if it is not a frequently used development plattform.

Regards,
Matthias
