Running make on CentOs system

[F2g-git]

Trying to install on centos 7 leads to an error upon calling make: help.c: In function ‘starthelp’: help.c:334:13: error: ‘OptionsHelpButton’ undeclared (first use in this function) button = OptionsHelpButton; ^ help.c:334:13: note: each undeclared identifier is reported only once for each function it appears in make[1]: *** [help.o] Error 1

That's definitely an error, so I will look into it. That said, however, I don't recommend compiling the Xt version, which is essentially crippleware since maybe 20 years ago. Make sure you install the prerequisite tcl-devel and tk-devel, and preferably cairo and fontconfig, and then run the configure script again.
