I'd like to tackle the find-the-font issue. CMake installs the font to
a platform-specific location. The easiest way to deal with that is to
simply hard-code this location in the C++ code and have it differ
between the branches, so in the master branch I've modified the code
pv_no_rendering.cc accordingly. It now does this:
- if the user has passed a font on the CL, that takes preference.
- next, lux will check the pwd. if the font isn't there
- lux will try and access the target-specific location, assuming it
has been installed on the local machine
You have hard-coded /usr/local in this check:
?????? "/usr/local/share/lux/Sansation_Regular.ttf"
Whereas (for example in Linux distribution package), this would be:
?????? "/usr/share/lux/Sansation_Regular.ttf"
Thanks for pointing this out - I did fear it wasn't as easy as my quick
shot :(
CMAKE_INSTALL_PREFIX defaults to "/usr/local", but can be set to
whatever location the builder likes (for rpm I'm setting it to "/usr").
Can you use this definition in a macro to compile-in the installed
location of the font?
Good question.
@Kornel: Maybe cmake can produce something like a pv_config.h header
which has such platform-specific information? That should not be too
hard - and it might be nice to maybe have a bit more platform-specific
info at hand, like the user's home directory, to put stuff in which
persists from session to session, and the location of the binary...
I wouldn't be surprised if cmake does that all the time - I'm just not
very good at it.
