Build fails due to missing sys/cdefs.h

[vranki]

I tried building linuxtrack on Ubuntu 15.04, with X-Plane plugin enabled.

Build fails:

Hello, the file you are missing is part of the libc6-dev-i386 package (assuming you run 64bit) - check if you have it installed and install it, if not. Then the compilation should work...

Kind regards,

Michal

PS. http://packages.ubuntu.com can help you with such problems...

Installing the package solves the issue. But shouldn't this be detected by configure script?

Hi, good question... Technically, I can't check for the package (every distro can name it differently, ...). What I can check for is the ability to compile in 32bit and if unsuccessful, I can turn off all the things that require it...

I'll think it through and see what I can do... Kind regards,

Michal
