'Unable to create file' when outside lazarus

[mike parr]

Hi  - I'm writing a text editor(on ubuntu) - I click  a button and it throws up  a save dialog, and writes some text to a file.  it runs fine under lazarus.
But when I run  the app outside lazarus (by double-clicking on the name) the program works up to the point of trying to save the file, giving the error:

    Unable to create file /home/mine/  .... the file name

I wondered if I am not setting an option in the IDE for free-standing execution?

thanks

Please give exact errormessage.
Also investigate what the value is of GetLasOSError if the error occurs.

Something like:

Code: [Select]

  try
    ...
    //save the file
  except
    on E: Exception do ShowMessage(E.Message + ' (#' + IntToStr(GetLastOSError) + ')' );
  end;
  ...

And post the code you use for writing to the file.

Thanks for the advice, Bart.   Much appreciated.

I tried a different approach - ran it with sudo - and it worked ok. (I also run laz as root). I recall that ubuntu has a unique approach to working as root, and this is the area I will look into.  I'm guessing that my problem is more ubuntu than lazarus.

Let me guess.

You run lazarus as root. Run the program from within Lazarus, create the file.
Now the file is owned by root.

Then you run the program as normal user  (by double-clicking on the name, as you said) , you try to rewrite the file that already exists, but that file is owned by root and cannot be written to by a normal user.

Change the ownership of the file to yourself (being normal user), something like

Code: [Select]

sudo chown <your username> <the filename in question>
