Hi - I can build the source on my intel powerbook no problems, but when i try to build on an intel xserve i get this error:- src/zope/interface/_zope_interface_coptimizations.c:1639: error: called object '&<erroneous-expression>' is not a function src/zope/interface/_zope_interface_coptimizations.c:1641: error: parse error before ')' token src/zope/interface/_zope_interface_coptimizations.c:1641: error: called object '&<erroneous-expression>' is not a function src/zope/interface/_zope_interface_coptimizations.c:1643: error: parse error before ')' token src/zope/interface/_zope_interface_coptimizations.c:1643: error: called object '&<erroneous-expression>' is not a function lipo: can't figure out the architecture type of: /var/tmp//ccXcO4kg.out error: command 'gcc' failed with exit status 1 If i run setup again i get this:- extensions/pyexpat.c:2037: error: array type has incomplete element type extensions/pyexpat.c:2032: error: request for member 'setter' in something not a structure or union extensions/pyexpat.c:2032: error: request for member 'itself' in something not a structure or union extensions/pyexpat.c:2032: error: called object '&<erroneous- expression>' is not a function extensions/pyexpat.c: At top level: extensions/pyexpat.c:2037: error: array type has incomplete element type lipo: can't figure out the architecture type of: /var/tmp//ccwH0Wxk.out error: command 'gcc' failed with exit status 1 And if i run it again it stops in the same place. The xserve is running 10.4.10 (Build 8R2218b). CalenderServer revision number 1895. Any ideas ? Thanks, Simon
