Re: [Wxart2d-users_dev] Cannot build from SVN

[Ryan T. <ry...@th...>]

Update on this - I ran the configure script with certain options and got
the build to work.  Freetype fails with errors, and removing the
"FindFreetype" Cmake script and rerunning it seems to fix the issue.

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

I'm using GCC 6.3.0 for this, and am getting these errors.

these errors:

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

The fix I found for those was to recast the values, such as "(char)0xFF"
instead of just "OxFF" at the lines.
