-Summary: The PHP5 module don't build
+Summary: _Offsetof() macro used but not defined on ARM/Clang
-Status: Open
+Status: Verified
Type: Bug
Package: Compile Failure
Operating System: FreeBSD10 / ARM
PHP Version: 5.4.11
Block user comment: N
Private report: N
New Comment:
The preprocessor conditionals in Zend/zend_ini.h test for '__arm' to decide whether
_Offsetof() is defined. The assumption is that this define is only set by ARMCC, the proprietary ARM
compiler, and not by others (like GCC). However, as Clang does set this define as well (in addition
to '__arm__'), the generated code ends up using a macro that is not defined, resulting in
the output as reported.
Note that rooting out these kinds of bugs is typical for porting to a new architecture, so filing
bugs against a stable version is not really appropriate.

It appears that this code is performing some tests to decide whether the CRAY or ARM proprietary
compilers are being used, and this is giving bad results on FreeBSD/ARM.
Could you set the the following #define *before* the #ifndef XtOffsetOf in Zend/zend_ini,h:30
#define XtOffsetOf __builtin_offsetof
and try again?

This has nothing to do with ARM.
Looking at the log, it appears that LLVM/Clang does not understand _Offsetof, and
treats it as an implicit function declaration and not a macro. Passing type names
to functions is not supported in C so it complains that it expects an expression
instead.

It could be interesting to try a snapshot of trunk from http://snaps.php.net/,
since some ARM fixes have recently been merged there,
