Re: error building root on RedHat 7.3

[I am just building Root 5.20 sufficient to use TNtuple, TDirectory,   and TFile in my program, linked statically; I am not trying the   root program that gets built, as I'm disabling just about everything.]

Thanks! That works on Mac OS X, as long as ROOTSYS is set to some value (any value will do, including "").

On Linux, using (ancient) gcc 3.2.1, I had to make two rather obvious edits to the Root source, and it works.

Now the problem is I cannot get Root 5.20 to compile on Windows. I'm using VC++ Express edition 2008 and Cygwin. Any suggestions:

     cl -O2  -nologo -FIw32pragma.h -MD -GR -EHsc- -W3 -wd4244 -Iinclude
            -D_WIN32_WINNT=0x0400 -I/usr/include/freetype2
            -Fograf2d/graf/src/TTF.o -c graf2d/graf/src/TTF.cxx
     TTF.cxx
     include\TTF.h(30) : fatal error C1083: Cannot open include file:
       'ft2build.h': No such file or directory
     make: *** [graf2d/graf/src/TTF.o] Error 2
     rm core/utils/src/RStl_tmp.cxx core/utils/src/rootcint_tmp.cxx

I tried --enable-builtin-freetype, but that caused other compile problems. I didn't need it on Mac or Linux.

The only instance of that file on this Windows system is in /usr/include/ft2build.h, but that seems unlikely to be useful.

FYI: cl gives:

I distribute on Mac OS X, Windows, and Linux. This greatly complicates things. For user convenience, I really need to include everything my program needs in my own installer (hence my desire to link statically).
