Hi,

I am getting the following compilation error when trying to compile version 5.0.2 software:

src/DOFrame.cpp:617:14: error: invalid conversion from ‘char*’ to ‘wxChar {aka wchar_t}’ [-fpermissive]

I have wxWidgets v. 2.8.12 package on Fedora version 3.9.10-100.fc17.x86_64

Has anyone seen this before?

Thank you,

Dmitry

I don't get this error under gcc 4.4.7, so I guess you have a newer version. Each one becomes more picky. Just try to replace

str += filename;

with

str += (wxString) filename;

in line 617 of DOFrame.cpp

Hi Stefan,

Unfortunately that did not work and from suggestions in the error I do see a good solution:

----------------------------

src/DOFrame.cpp: In member function ‘void DOFrame::LoadConfig(char*, int)’:

src/DOFrame.cpp:617:25: error: call of overloaded ‘wxString(char [1024])’ is ambiguous

---------------------------------

let me know if you see one.

Thank you,

Dmitry.
