[Insight-users] compile problem on OpenBSD

[Amit Kulkarni]

Hi Luis,

Will you please check the file? There are two successive #if
defined(VCL_BORLAND) sections, I deleted the offending section of #if
defined(VCL_BORLAND) at the bottom and left the top section alone. Now it
maybe wrong of me, but I couldn't figure out why somebody had left two
almost identical #if defined(VCL_BORLAND) sections. And why is gcc going
into those sections?

It compiled taht particular file okay.

It is giving some other compile problem.

Is it possible for somebody to try and compile on OpenBSD -current in a
virtual machine? Its compiler (which is a gcc 4.2.1) is causing problems
which didn't happen on Opensolaris (many versions) or Ubuntu or Windows XP
or WIndows 2003 Server or Windows 7.

Thanks
