Problem installing Delphes

[sarellis]

When installing Delphes in the madgraph5 environment, I get the following error:

Compiling classes/DelphesTF2.cc

classes/DelphesTF2.cc:32:12: error: use of undeclared identifier 'kVariable'

action = kVariable;

I determined that kVariable is a member of the TFormula class of ROOT, so figured re-installing ROOT might help, but it did not.

I already asked in the MG5 forum, and was referred here.

Any ideas would be appreciated.

Could you, please provide more details about your system (OS version, ROOT version, how you installed ROOT)?

[sarellis]

Thanks for getting back to me. The details are:

Mac OS 10.10.2
ROOT version 6.02
Installed from source

[sarellis]

Any word on what the problem may be?

I have problems building ROOT 6.02.05 on MacOSX. So, unfortunately, I can't reproduce this problem.

I can build Delphes 3.2.0 with ROOT 6.00.02 on MacOSX 10.10.1 without any problem.

Could you share the commands/patches that you used to build ROOT 6.02?

Just for information, here is the error message that I get when building ROOT 6.02.05:

root-6.02.05-source/graf2d/graf/src/TTF.cxx:221:26: error:
      use of undeclared identifier 'FT_Done_Glyph'
      if (glyph->fImage) FT_Done_Glyph(glyph->fImage);

[sarellis]

I did not get this error. When I built root I ensured I had installed python--dev beforehand, then before making, I invoked

./configure --enable-python
make

Not sure if that would make the difference.

I installed an earlier version of root, 5.34, and got Delphes installed just fine with that version.

The following ROOT forum thread helped me to build ROOT 6.02.05:

​https://root.cern.ch/phpBB3/viewtopic.php?f=3&t=19102

Here is the command that I used:

./configure macosx64 --enable-gdml --enable-minuit2 --enable-roofit --enable-table --enable-unuran --disable-cocoa --disable-fink --enable-builtin-freetype --enable-x11 --enable-cxx11

However, I could not reproduce your problem with kVariable. I can build Delphes 3.2.0 with ROOT 6.02.05 without any error message.
