Hi, all
 
is there any function can be used to calculate the middle point of  the
closest approach between lines?
or I have to write my own ?
 
tks

I tried doing that, and ended up unable to build Mesa at all.  I finally
managed to build it successfully by not building most of the demo
programs, and that seemed to work.  I had all the necessary libraries.
However, the VTK build still fails in the exact same way.  I'm at a loss
here - any other ideas what I may have done wrong?

 

Thanks!

Shari

It depends on what platform you compiled Mesa. Say, if you use make
linux-x86 to build Mesa, you may also have to edit the configs/linux
with the same option.

good luck.

I used these compiler flags in configs/default:

 

# Compiler and flags

CC = cc

CXX = CC

CFLAGS =  -DUSE_MGL_NAMESPACE -O

CXXFLAGS = -DUSE_MGL_NAMESPACE -O

GLU_CFLAGS =

 

Is that right?

 

Thanks again!

did you add -DUSE_MGL_NAMESPACE option when compiled Mesa?

Hi,

I'm trying to build VTK 5.0.2 with mangled Mesa support.  I have
followed the instructions found at
http://www.vtk.org/Wiki/VTK:How_I_mangled_Mesa, but cannot build VTK.

I have listed the build errors below.  Any help would be appreciated.

Thanks, 
Shari
