Hope it is OK to ask a question about installing Netgen on this OpenFOAM forum.

I have been using Netgen in Windows and OpenFOAM in SuSE 9,2 for a while. Obviously it's not ideal to reboot to switch program, so I have tried to install Netgen in SuSE Linux 9.2, but have run into some problems:

In the README.INSTALL it is described to hack the makefile by adding:
setenv MACHINE LINUX

when running "make", I get the following errormessage:
Makefile:4: *** missing separator. Stop.
Anyone?
Needless to say I'm not very experienced in Linux.
Best Regards

Sounds like your makefile got 'corrupted'. Did you edit or copy/paste your Makefile under Windows or copy it from Windows? This might cause problems. Just unpack the original sources.

This is what I get:

Unix> setenv MACHINE LINUX
Unix> make
cd libsrc; make
make[1]: Entering directory `/home/pinky2/mattijs/pub/ngs44/libsrc'
make[2]: Entering directory `/home/pinky2/mattijs/pub/ngs44/libsrc/linalg'
..

Thanks for reply, Mattijs

I found out that the first problem was that despite I had bash on my computer (SuSE 9,2), I had to use the command "export MACHINE=LINUX" instead of "setenv....

Anyway, I still get error messages.

What I have tried to so far according to tips in the REDME.INTALL file is:

- Problems with Tcl.init:
export TCL_LIBRARY=/usr/lib/tcl8.4
export TK_LIBRARY=/usr/lib/tk8.4
export TIX_LIBRARY=/usr/lib/tix8.1
-which is the versions and location according to my installation.

This is what I get:

Anyone seeing the solution?

[mattijs]

You'missing some files (GL/, tcl.h etc.) in /usr/include.

Your can install them from your suse9.2 cd. Just install all of the development libraries and sources .

[edvardsenpriv]

Sorry to keep nagging, Mattijs, but I think I'm almost there. Installing development packages helped. The error messages has been narrowed down to:

lars@linux:~/ngs44>


I can find and open the C++ Header File "meshtype.hpp" and read line 965 to 975, but can't figure what the problem is. Anyway the code here says:

XXXXXXXX line 962 XXXXXXXXX
{
private:
Mesh & mesh;

/// identify points (thin layers, periodic b.c.)
INDEX_2_HASHTABLE<int> * identifiedpoints;

/// number of identifications (or, actually used identifications ?)
int maxidentnr;

public:
///

///
~Identifications ();

void Delete ();

/*
Identify points pi1 and pi2, due to
identification nr identnr
*/
void Add (PointIndex pi1, PointIndex pi2, int identnr);


int Get (PointIndex pi1, PointIndex pi2) const;
int GetSymmetric (PointIndex pi1, PointIndex pi2) const;
///
INDEX_2_HASHTABLE<int> & GetIdentifiedPoints ()
{
Thanks, so far.

[niklas]

What happens if you remove the space
between Mesh and &.

Plus i think you should add the -fpermissive flag to the makefile.

N

[mattijs]

In meshtype.hpp line 957 I added

class Mesh;

and that seemed to help with that one.

[edvardsenpriv]

Thanks for all tips,
"class mesh;" solved that problem.
(I'm afraid I don't know enough about C++ to know how to ad a -fpermissive flag, or what it means)

Then it was the thing about right version of the tkInt.h file in the togl directory, wich was fixed.

But I still keep getting errormessages, now its:

Still hoping,
Lars

Actually I also had problems installing netgen on suse so then I installed it on win xp under cygwin. It works fine... You should try that if everything else fails.

How/where did you install Tcl/Tk + Tix + Mesa? In which directories? Did you follow the installation instructions (readme's) and get no errors?

As I remember it, I once screwed up the Mesa installation and then I got tired of trying... Also, as I remember it, tcl/tk should be in your path but I also think you can install some of these programs with the suse installation (yast?) program.

I think I'll try installing it on suse again later but I agree it's not straightforward. I don't know if it helped you anything but perhaps you should try the cygwin solution.

[mattijs]

Are you compiling with gcc4? You could try compiling with an older version of gcc. Gcc4 is more strict.

[niklas]

Hey Mattijs,
did u try adding -fpermissive?
I found this flag very useful for the AIX system.

N

[mattijs]

No haven't. For what software do you need this? I hope not OpenFOAM?

[niklas]

nope, but paraview for instance will not compile without it.

N

[edvardsenpriv]

I installed Tcl/Tk + Tix with YaST under /usr/lib/, but used export TCL_LIBRARY=/usr/lib/tcl8.4 etc. to set the variables.

I am compiling with gcc 3.3.4...

Hey Niklas, I understand (now) -fpermissive allows for non-conformant code. But what exactly do you write, and where in the makefile?
Any risks?

LE

Hello, Lars.

I don't know what's wrong with you installation, but today I got netgen running on my home computer after I saw it being installed on another computer by a more experienced linux user. Both systems ran suse 9.3, and I can see that you're almost there since the last problem I had also was with the togl/ directory (the first problems was correctly as Mattijs writes about missing files in /usr/include).

Once you get to this problem below which I've now seen 2 times today on 2 different linux pc's:

togl/togl.cpp:144: error: ISO C++ forbids declaration of `Sorry' with no type
togl/togl.cpp:144: error: ISO C++ forbids declaration of `you' with no type
togl/togl.cpp:144: error: syntax error before `have'

Then you'll have to follow the instructions from the netgen homepage section trouble shooting:

I have compilation problems with "togl/togl.cc"

Togl by Brian Paul and Ben Bederson provides the link between Tcl/Tk and OpenGl rendering. It requires internal tk-header files, which are included for several tk-distributions (like tkInt8.0.h). If you use newer Tcl/Tk versions, please copy the file "tkInt.h" (from the Tk-source directories) to the togl directory (e.g. to tkInt8.2p2.h), and adapt togl.cc (about line nr 120).

In my case, I then changed the togl.cpp around line 120 like this:

#elif TK_MAJOR_VERSION==8 && TK_MINOR_VERSION==4 && TK_RELEASE_SERIAL==9
# include "tkInt.h"
#else
Sorry, you will have to edit togl.c to include the right tkInt.h file
#endif

Since my version of tk was 8.4.9-9, the program would jump to the "Sorry, you.." and this explains the error since the code has problems with newer versions! The tkInt.h was copied from /usr/include/tkInt.h to current togl-directory and when you then do a "make" again, compilation will take about 15 minutes and you're done.

Compiler was gcc (GCC) 4.0.1, no need for -fpermissive or anything else mentioned in this thread. Since I also used:

export TCL_LIBRARY=/usr/lib/tcl8.4
export TK_LIBRARY=/usr/lib/tk8.4
export TIX_LIBRARY=/usr/lib/tix8.1

Then our systems must be much alike.

Good luck, I think you should start completely from scratch again and don't edit anything else but togl.cpp! I hope this was good news for you...

You're actually very close to completing the installation. I think your problem is that you changed something in the other source files... Let me know if this helps.

[edvardsenpriv]

Thanks for tips, Martin.

I'm happy for you fixing the problem on your computer. The only difference I undertand between the two system is that I run suse 9,2 and gcc 3.3.4 instead of suse 9,3 and gcc 4.0.1. Strangly enough I have done quite the same as you, but keep getting the same errormessage as before.

I have tried to follow the tip about -fpermissive as well by adding this after CPLUSPLUSFLAGS = in Makefile (not all Makefiles).



The errors are still:

Something with 'class netgen' ? Could I still be missing some development libraries?

Lars

[edvardsenpriv]

By the way, Martin. Where did you install netgen, in /home/username/ngs44 or /usr/local... and how does the structure look like?

A general question; I understand that when building from sources, it is usually three commands that has to be used:
./configure
make
make install
Have I understood it right as for programs like netgen, where there already exists Makefile, the ./configure command is skipped?

Hi,

I installed it in /home/martin/ngs44 since I'm the only linux user on both machines, but I guess on a multiuser system it would be better to place it in /usr/local? Not so important, though (still compiled as root).

Actually as I remember it I think I only did "make" and used yast to install the necessary development stuff.

I think you need to open yast and install some more devel libraries and don't worry about classes + flags etc. Do you have something named ?-x11-?-devel installed (can't remember the exact name), and also development libraries for tcl/tk + tix? NOTICE: Look for the files in /usr/include if in doubt. Then you'll know whether you need more devel libraries or not.

I didn't install mesa this time and only used yast for installing what was missing (didn't grab the files from the netgen download page).

I still think you shouldn't change anything but the togl.cpp so I would start all over if I were you.

----- BTW:

Anyone got any hints on how to get STEP/IGES import functionality working with netgen?

I tried to install OpenCASCADE with java -jar setup.jar (don't remember the exact filename, but the installer just exited). Binary files should be in /opt/? but I can't even start the program...... I then did a "make" in the netgen installation directory again and this time compilation took more than 1 hour, but still I can't import IGES/STEP files on suse 9.3.

Anyone, perhaps Mattijs got any hints?

[edvardsenpriv]

Fantastic, I finally made it! The only difference now (as far as I have registered) was that I compiled as root. Thanks for help so far.

...anyway when trying to build the IGES/STEP OpenCascade module, I get the errormessage:

/usr/lib/gcc-lib/i586-suse-linux/3.3.4/../../../../i586-suse-linux/bin/ld: cannot find -lTKIGES
collect2: ld returned 1 exit status
make: *** [ng] Error 1
linux:/home/Lars/ngs44 #

...but then again its stated on the Netgen website that:
"At present, only the NETGEN version downloaded via CVS access supports the installation of the OpenCascade kernel."
(Anyhow it does work in the windows version)

[colinss]

Any one succeeded in compiling negen on linux with OpenCascade kernel?

I can compile it without the kernel but have difficulties with it.

Any suggestion will be appreciated.
