Description

I wrote a c++ program that writes out some content into a file which is located in a shared folder which is supposed to be read/write (full access) I compiled it with gcc -g

" ostringstream tempvar44; (gdb) n 3176 fstream F; (gdb) n

3177 open(F, (tempvar43 << ">" << ofilename, tempvar43.str()))
die((tempvar44 <<"could not write "<< ofilename << "\n", tempvar44.str()));

" at this line , the program freezes. It cannot be killed inside the guest kanotix linux. I have Windows Xp.

Could you please post a complete programme which exhibits this behaviour? Thanks.

I could not make a smaller working program yet. However, it had to do with the guest folder as when I copied the file into a linux folder, The freezing no longer occured.

I mean when I ran my program on the copied version of the file, there was no freezing.

Michael's intension was to get a small sample application which allows us to reproduce the problem. In the subject you posted some code fragments. Could you post/atach a the code of a small application which can be compiled with gcc/g++?

  • Status changed from new to closed
  • Resolution set to fixed

There were some fixes to shared folders with Linux guests with VBox 3.0.2. Please reopen this ticket if the problem persists and provide a compilable example in that case.
