Compilation error... eyes needed

I just can’t see what’s wrong with my code, so here it is maybe i get lucky.

The errors:

/boot/home/Desktop/roller/DeskbarView.cpp:81: parse error before character 0302
/boot/home/Desktop/roller/DeskbarView.cpp:85: syntax error before `.'

Try using GCC7; it has much better error messages.

Have you cut&paste from the BeBook? I didn’t see this error since the BeOS time.

It’s a typical GCC error connected with copy and paste from certain sources (which by the way is not going to get any better with GCC7). What happened is that while you copied data from a website or similar source a non ASCII white space or punctuation has been copied. It looks like an ASCII character but is none. Lexers react badly to this. I see this kind of error often when copy-paste seemingly simple stuff from OpenGL API website. To fix it delete the text or line in question and type it anew by hand. This will remove the bogus character (often hidden by editors too). This should fix the problem.

Use a proper editor which highlight these :slight_smile: (vim has the “listchars” option for this).
Usually it’s a non-breakable space instead of a normal space.

Thanks to all, for trying to help, i may have copy pasted from the bebook indded, i fixed it by opening the file in another Qt editor (FeatherPad) which can show whitespaces, fixing those made the error go away.
