On my system (Scientific Linux 5 32 bit with custom-built gcc 6.3.0) I get this error when compiling version 10.03.p02 with -DGEANT4_USE_GDML=ON (with both Xerces-C versions 3.1.4 ans 3.2.0): In file included from /wizard/02/software/source/geant4.10.03.p02/source/analysis/g4tools/include/tools/raxml:9:0, from /wizard/02/software/source/geant4.10.03.p02/source/analysis/xml/include/G4XmlAnalysisReader.hh:44, from /wizard/02/software/source/geant4.10.03.p02/source/analysis/xml/src/G4XmlAnalysisReader.cc:30: /wizard/02/software/source/geant4.10.03.p02/source/analysis/g4tools/include/tools/xml/loader: In member function 'bool tools::xml::loader::parse_buffer(size_t, const char*, XML_StartElementHandler, XML_EndElementHandler, void*)': /wizard/02/software/source/geant4.10.03.p02/source/analysis/g4tools/include/tools/xml/loader:221:9: error: 'XML_Index' was not declared in this scope {XML_Index pos = XML_GetCurrentByteIndex(_parser); ^~~~~~~~~ The error is present also in version 10.03.p01.
The error persists also with -DGEANT4_USE_GDML=OFF, so it's probably unrelated with this setting (and maybe also with the Xerces-C version).

I found that he problem is due to the fact that in my build the system expat is used, which is rather old: -- Found EXPAT: /usr/lib/libexpat.so (found version "1.95.8") and which does not contain the XML_Index typedef in expat_external.h. I think that the CMake configuration should enforce a minimum required version for system expat in order to avoid this problem. Anyway, configuring the build with internal expat using -DGEANT4_USE_SYSTEM_EXPAT=OFF fixes the build.
A version check on the system expat has been introduced in tag cmake-V10-03-36 (will be in 10.4 and any additional patches to 10.3). If the system version isn't sufficient, then an error will be emitted indicating the issue and recommending the use of the vendor "G4expat". The minimum version of expat supported has been identified as 2.0.1. Ivana, this can be marked as RESOLVED FIXED.
