I am getting an error in vtkCSVWriter.cxx when using gcc 4.8.5 to build ParaView 5.7.0-RC2
This seems to have been introduced by the change last week to fix issue #19224 (Save Data, csv file,
from streamtracer is bad)
Build\_5.7.0-RC2\_mesa/superbuild/paraview/src/ParaViewCore/VTKExtensions/Default/vtkCSVWriter.cxx:203:18: error: use of deleted function ‘std::basic\_ofstream& std::basic\_ofstream::operator=(const std::basic\_ofstream&)’
this-\>Stream = ofstream(filename, ios::out);
/usr/include/c++/4.8.5/fstream:599:11: note: ‘std::basic\_ofstream& std::basic\_ofstream::operator=(const std::basic\_ofstream&)’ is implicitly deleted because the default definition would be ill-formed:
class basic\_ofstream : public basic\_ostream\<\_CharT,\_Traits\>
Thanks,
Joe

The patch did not fix the error sadly:
Here is more detail on the errors I get even with the changes made by Utkarsh applied:
/home/joeh/PV/Build\_5.7.0-RC2\_mesa/superbuild/paraview/src/ParaViewCore/VTKExtensions/Default/vtkCSVWriter.cxx: In member function ‘int vtkCSVWriter::CSVFile::Open(const char\*)’:
/home/joeh/PV/Build\_5.7.0-RC2\_mesa/superbuild/paraview/src/ParaViewCore/VTKExtensions/Default/vtkCSVWriter.cxx:204:18: error: use of deleted function ‘std::basic\_ofstream& std::basic\_ofstream::operator=(const std::basic\_ofstream&)’
this-\>Stream = ofstream(filename, ios::out);

I am not sure you got the latest patch…attached…there’s no `this->Stream = ofstream(...)` in the code anymore.

Utkarsh,
You were correct, I got the new version of the patch and now it is working.
Thanks for your quick reply,
Joe
