[Insight-users] ITK build for Linux crashes : second thought

[Luis Ibanez]

Interesting,...

Without libfltk_gl.a,

programs like ThinPlateSplines should not link....

This doesn't seem to have changed in FLTK.

In my build of FLTK 1.1.3 the library libfltk_gl.a
is still created. And verifying with "nm -C" it is
the only one, out of the four libraries, that contains
the symbol "Fl_Gl_Window".

There seems to be something very particular about
your system...

Is this a recent Linux ?
Do you use Mesa to provide OpenGL functionalities ?
Is the system file: Gl/gl.h   in a visible place ?

You may want to double check the log generated by
./configure in the FLTK directory. It may have happend
that it reported and error that prevents it from
building the OpenGL related library.

We have build FLTK in a variety of systems ranging
from SGI, SUN, Windows, Linux and Mac.... the opengl
library is created in all of them.


Please let us know if you find any hints,


Thanks


Luis
