Dear list,
I think I got the point, in captcha.cpp:46 there must be a font
name that it exists. No fallback is done.
In my system I executed "fc-match Monospace," and the results was
Inconsolata I replaced "helvetica" with "Inconsolata" and cppblog
still crashed for the lack of /usr/share/fonts/Type1/n019003l.pfb.
This file is part of the gsfonts package, once I also added the
package cppblog halts with this error:
Failed: No configuration defined
That I think is expected since I just executed it from the
compilation directory.
So, I think the fact that the font name on the captcha.cpp:46
must be exact and that gsfonts must be installed should be added
to the documentation.
I hope I am fine now, in the case I'll share here.
Cheers,
Paolo
