invalid command name "Ng_STLDoctor"

[Thomas]

Hi,

I have installed netgen with the GUI. When I try and run ./netgen, I get the following:

NETGEN-5.3.1
Developed by Joachim Schoeberl at
2010-xxxx Vienna University of Technology
2006-2010 RWTH Aachen University
1996-2006 Johannes Kepler University Linz
optfile ./ng.opt does not exist - using default values
no OpenGL
Error in Tcl-Script:
result = invalid command name "Ng_STLDoctor"

Make sure to set environment variable NETGENDIR to directory containing ng.tcl

I have set NETGENDIR to the directory containing ng.tcl, but the error persists.

Note: As I don't use STL files, a quick workaround I found was to open ng.stl and delete the Ng_STLDoctor line.

P.S. For posterity, I'll outline the steps I took for anyone wanting to install netgen on CentOS 6.6

1) Download tcl8.5, tk8.5, and togl1.7 from these directories
https://www.tcl.tk/
https://sourceforge.net/projects/togl/files/Togl/1.7/

2) Untar all three.

3) ./configure and make all three (You do not need to make install)

4) Download netgen 5.3.1 and untar it.

5) cd into the top directory and enter the command ./configure --prefix=path/where/you/want/netgen --with-togl=path/to/Togl1.7

6) make

7) If an error regrarding lTogl is thrown, cd into ng, open the makefile, identify the line

-L$(TK_BIN_DIR)/Togl1.7 $(TOGLLIBDIR) -lTogl $(LIBGLU) $(TK_LIB_SPEC)...

and replace -lTogl with -lTogl1.7

Also, locate the line "TOGLLIBDIR=/path/to/Togl$" and delete the $ sign.

rerun make.

Done! (Run make install if you like too)
