Rootcint dies in v5.28.00.patches

VIVE L’AMOUR!
I am trying to get the newest “v5.28.00.patches” working on an Ubuntu 10.04.1 LTS (i686, gcc 4.4.3).
I configured it enabling all possible options:

Enabled support for asimage, astiff, builtin_afterimage, builtin_ftgl, builtin_freetype, builtin_glew, builtin_pcre, builtin_zlib, cintex, clarens, editline, exceptions, explicitlink, fftw3, gviz, gdml, genvector, gsl_shared, krb5, ldap, mathmore, memstat, minuit2, mysql, opengl, peac, python, qt, qtgsi, reflex, roofit, ruby, rpath, shadowpw, shared, soversion, ssl, table, tmva, unuran, x11, xft, xml, xrootd.

  1. “make” created all expected libraries and executables (I hope)

  2. “make qtcint” died with an “Error: Symbol longdouble is not defined in current scope /usr/include/qt4/QtCore/qglobal.h:2086:” where the line 2086 is:
    Q_DECLARE_TYPEINFO(long double, Q_PRIMITIVE_TYPE);

  3. “make install” installed everything existing into my ROOTSYS

  4. rootcint is unusable - I tried to “cd test” and do “make”, but I got:

rootcint -f EventDict.cxx -c Event.h EventLinkDef.h

*** Break *** segmentation violation

(rootcint is “hanging”, one needs to kill it with a Ctrl-C)

I am stupid. No?

I’m sorry, did I say “help”? :-k

I reconfigured and recompiled v5.28.00.patches with “–build=debug”. ](*,)
It seems that the “dictpos” pointer is NOT initialized.

Hi,

just to let you know: I can confirm this bug; I am working on it. Please just sit back and wait, I expect to have it fixed in a few hours.

Cheers, Axel.
