Installation Errors @ Red Hat

Same issue on Slack64 13.0. Any assistance will be greatly appreciated.

Make sure that you install FTGL library. Or you may install previous versions of OCC like 6.3.0 without FTGL. This headers is need only to show text in OpenGL.

Tried that and got the same errors.

On the Debian and Fedora linux build cool. Check you have /usr/include/FTGL directory or not. Also you don't need ftgl library, only sources

I have /usr/include/FTGL. Put source code in it?

Thanx

Don't copy this headers, in my project I have next:

INCLUDEPATH += /usr/include/FTGL \
/usr/include/freetype2

this includes only need for TkOpenGL librarys.

I don't know how configure with cmake and other, but I have Qt Creator *.pro files for all OCC sources:

http://www.opencascade.org/org/forum/thread_19175/

You may open OpenGL.pro file and see how to include headers of FTGL and freetype library into OCC.

I get the same error on Mac OS X Lion 10.7.3
Installed FTGL from source and used --with-ftgl option still getting the same error. Are there other dependencies?

See http://www.opencascade.org/org/forum/thread_20128/

exact same problem here. what has to be done?

I've followed to the T the instructions given and still can't compile. What gives?

Linux 64 bit.

I mean I followed the instructions given in the pdf that comes with OCCT (Building of OCC Tech 6.5.2 on Linux

thanks in advance.

If anybody has built a version on rhel 6.0, why can't it be shared ?

Hi all,

After at all, i found the solution to find compiled codes. It is easy to install on debian system, not RedHat. And I had success about that,i wrote in my blog (sorry but in Turkish):

http://www.kocakbilisim.com/uk/2011/07/open-cascade-giris/

and translateed version (by google translate):

http://translate.google.com/translate?sl=tr&tl=en&js=n&prev=_t&hl=en&ie=...

Exactly the same issue with OCC 6.5.3. Apparently the developers have not tested the new release for old REPORTED builds issues. *Sigh*
