Hi,
I can compile and run OCAF sample in Windows. Since there is not an OCAF sample in Linux, I try to make my own. Undo-redo function works fine. But when I want to implement saving file, I got the following error.
.so: cannot open shared object file: No such file or directory
I have set the following environment variables, and put the files Resources and Plugin in res directory. I make the setting the same as in Windows.
export CASROOT=/opt/OpenCASCADE6.2.0/ros/
export LD_LIBRARY_PATH=/opt/OpenCASCADE6.2.0/ros/lin/lib/
export CSF_PluginDefaults=res
export CSF_NewFormatDefaults=res
Does anybody has ever successfully make OCAF application in Linux? Will you share your experiences? Thanks.

Hi Umar,
I use OCAF on Linux and Mac OSX. For the Mac I have:
export CASROOT=/Users/totty/Projects/OpenCASCADE6.1.0/ros
#export CSF_GraphicShr
#export CSF_CurrentUnitsDefaults
#export CSF_CurrentUnitsUserDefaults
export ResourceDebug=1
export CSF_PluginDefaults=res
export CSF_PluginUserDefaults=res
export CSF_ResourceVerbose=1
export CSF_ResourcesDefaults=res
export CSF_SHMessage=res
export CSF_STEPDefaults=res
export CSF_XSMessage=res
export DEBUGMODE=1
export MMGT_VERBOSE=1
export DISPLAY=:0.0
Could you paste the files res/Plugin and res/Resources?

Thanks Torsten for your response.
Below are files of Plugin, Resources, run.sh and output of executable file in console. I have also tried to append .so to plugin such as FWOSPlugin into FWOSPlugin.so as suggested on the Ocaf documentation. But I got the same result.
Could you send me your code and script for environment settings to umarsaid at yahoo.com ?

Hello Umar,
this is my SaveAs method. As you can see, there is the original windows code still in evidence.
void Document::onFileSaveAs()
{
QString s = QFileDialog::getSaveFileName(
"/home/totty/Diss",
"tcad Files (*.tcad *.xtcad)",
0,
"save file dialog",
"Choose a file" );
if (!s) return;
Handle(TOcaf_Application) m_App= getApplication()->getOccApp();
// SetTitle(s);
QApplication::setOverrideCursor( Qt::waitCursor );
// CString CSPath = dlg.GetPathName();
// if((CSPath.Find(CString(".sta")))==-1 )
// CSPath = CSPath + ".sta";
cout << "Save As " << s << endl;
// PathName=CSPath;
// Standard_CString SPath = (Standard_CString) (LPCTSTR) CSPath;
Standard_CString SPath = (Standard_CString) qstrdup(s);
TCollection_ExtendedString TPath(SPath);
cout << TPath << endl;
// save the document in the current application
TCollection_ExtendedString status;
m_App->SaveAs(myOcafDoc,TPath,status);
cout<

I use your code but the same error still occurs. I think it is not about the code or Resources file. As you can see, before saving, plugin must be loaded. That's the point where my program failed, as seen on console output above.
.so: cannot open shared object file: No such file or directory
In fact, when I check with IsDriverLoaded(), the driver is not loaded. This is before calling to SaveAs(myDoc,TPath,status). So when I call SaveAs while the driver not loaded, the program exit. I suspect this is caused by wrong Plugin file or environment variables. Could you send me your Plugin file and environment variables?
Thank you very much.

There are strange apostrophies in your console output. Is this just a copy Problem or is there a real error?

The content of your Plugin file is the same as mine. The only difference is that in my file, new line is marked with OA (CR) while yours with OD OA (CRLF). That's why the console output is 'ey = instead of Key =. That's why the program cannot open it and then not load it.
I don't know where I got that kind of newline. But aside from my carelessness, I think OpenCascade should be more robust by being able to read line regardless what type of newline we use.
Torsten, thank you so much for giving me your file. Now I can continue my experiment with OCAF.
