Compiling under Linux

Compiling under Linux
Paolo Mosna 2002/09/26 15:57
Hi, I would like to try to compile the exoTK core libraries and exoTKAD under Linux.
What do I have to do?

Thanks.
Paolo.
Stephane Routelous 2002/09/26 18:23
Hi Paolo,


first, download OpenCASCADE and install it on Linux.
second, download the exoTK sources from sourceforge (http://sourceforge.net/project/showfiles.php?group_id=37373&release_id=88016 )
and unzip them in the directory of your choice.

from http://sourceforge.net/project/shownotes.php?group_id=37373&release_id=88016 :
Notes: This archive contains the sources of exoTKAD, and of the exoTK library. To compile the library and the programm, you have to download OpenCASCADE from http://www.opencascade.com . To compile and run the DX3DS plugin, you have to download and install lib3ds ( http://sf.net/projects/showfiles.php?group_id=4041 ) To compile and run exoTKAD on Linux, you have to download ans install Qt3.0 ( http://www.trolltech.com/developer/download/qt_x11.html ). To compile and run exoTKAD on Windows, you need to have VisualC++ 6.0 with the lat service pack installed.

download and install the previous libraries.

go in the directory where you unzipped exoTK.
you should be able to launch :
qmake all_qt.pro
It should compile all.

If you have any problem, drop me a line.


Thanks for your interess in exoTK.

Hi Stephane

I have some more problem with linux:

On my system `qmake all_qt.pro` doesn't compile but only produce a Makefile.
So after that I have given a `make` and indeed a lot of compiling has been done.
At the end the command exited with the following message:

.....

make[3]: Leaving directory `/home/walter/EMSIM/exotk/exoTK/plugins/DXBRep'
make[2]: Leaving directory `/home/walter/EMSIM/exotk/exoTK/plugins'
make[1]: Leaving directory `/home/walter/EMSIM/exotk/exoTK'
cd exoTKAD/Qt && qmake -o Makefile
Usage: qmake [mode] [options] [files]

QMake has two modes, one mode for generating project files based on
some heuristics, and the other for generating makefiles. Normally you
shouldn't need to specify a mode, as makefile generation is the default
mode for qmake, but you may use this to test qmake on an existing project

Mode:
-project Put qmake into project file generation mode
In this mode qmake interprets files as files to
be built,
defaults to *.cpp; *.l; *.y; *.ui
-makefile Put qmake into makefile generation mode (default)
In this mode qmake interprets files as project files to
be processed, if skipped qmake will try to find a project
file in your current working directory

Warnings Options:
-Wnone Turn off all warnings
-Wall Turn on all warnings
-Wparser Turn on parser warnings
-Wlogic Turn on logic warnings

Options:
* You can place any variable assignment in options and it will be *
* processed as if it was in [files]. These assignments will be parsed *
* before [files]. *
-o file Write output to file
-unix Run in unix mode
-win32 Run in win32 mode
-macx Run in Mac OS X mode
-d Increase debug level
-t templ Overrides TEMPLATE as templ
-tp prefix Overrides TEMPLATE so that prefix is prefixed into the value
-help This help
-v Version information
-after All variable assignments after this will be
parsed after [files] [makefile mode only]
-cache file Use file as cache [makefile mode only]
-spec spec Use spec as QMAKESPEC [makefile mode only]
-nocache Don't use a cache file [makefile mode only]
-nodepend Don't generate dependencies [makefile mode only]
-nomoc Don't generate moc targets [makefile mode only]
-nopwd Don't look for files in pwd [ project mode only]
-r Recursive search [ project mode only]
make: *** [exoTKAD/Qt/Makefile] Error 154

Hi Walter,

you can check that the file exoTKAD.pro is in the folder exoTKAD/Qt
If the file is there, you can try to run "qmake exoTKAD.pro"
Which version of Qt do you have ?

Stephane
walter steffe 2003/02/06 16:43
Thanks for help

I have Qt 3.0.5 (that one included in the last Suse distribution, that is last update of Suse 8.1).

Your advice worked fine for qmake exoTKAD.pro but when I entered another make in the exotk root dir I got a compilation error for exoTKAD_Application.cpp:

.....

Hi Walter.

It seems you don't use the same compile as mine.
Which one are you using ?

in exoTKAD_Document.h line 61 :
replace
friend exoTKAD_View
with
friend class exoTKAD_View


in PJLogWidget.h line 49
replace
#endif !defined (_PJ_LOGWIDGET_H_INCLUDED_)
with
#endif // !defined (_PJ_LOGWIDGET_H_INCLUDED_)

I have gcc 3.2-39.
I have set QMAKESPEC=linux-g++ and so I am using gcc. An other option was to use icc7.0 which is also installed on my system but I have chosen gcc because OpenCascade is compiled with it. I am not sure that the two can be mixed.

After having made the suggested replacements I have found the need of another similar substitution in exiTKAD_View.h line 54.

Then I have encountered a different error:

Stephane Routelous 2003/02/06 19:23
If I remember correctly, I was using gcc2.9.something.
Mainly because I heard of compatibility issues with the newest versions.

I will check later with the new gcc.

About your errors, min and max should be declared in stdlib.h

if not, declare the macros
#define min(a, b) (((a) < (b)) ? (a) : (b))
#define max(a, b) (((a) > (b)) ? (a) : (b))

HTH
walter steffe 2003/02/06 21:13
It seems to me that the definition of min and max is really needed. I have tried also with Intel icc 7.0 and I got the same complain about min and max. This is the last syntax error given by both compilers but now I am getting a lot of undefined references, many hundreds of them. Just to give a somple look at the following listing:

For this one, I think the OCC libraries are not found.
Check that TKernel is included in the Makefile.
If it is, check if you have CASROOT defined.
walter steffe 2003/02/07 07:45
TKernel is included and CASROOT is defined.
The problem is that CASROOT is referenced as $(CASROOT) instead of ${CASROOT}.

The same thing applies to many other variables sparsed in the various Makefiles. May be it is better to make the change in the project files.

Stephane Routelous 2003/02/07 11:33
perhaps Trollltech changed qmake, because it worked fine.

walter steffe 2003/02/07 19:25
I am sorry I have said a stupid thing.
$(CASROOT) in the Makefile is ok (I have confused with the sintax of the bash shell).


libTKernel.so is linked for sure because if I remove the $(CASROOT) I get a message saying that the linker is not able to find it.

So I can not understand what is happening.
The long listing of undefined references comes out in the last step: the making of the TARGET = exoTKAD.
