2010-02-10Merge branch 'pan/enable_m32_build' into ccase/r13b04_devErlang/OTP
* pan/enable_m32_build: Teach configure --enable-m32-build for forcing a 32-bit build OTP-8415 configure learned the option --enable-m32-build to force the building of a 32-bit run-time on systems where the default C compiler generates 64-bit executables by default.
2010-02-08Merge branch 'gc/hipe_darwin_amd64' into ccase/r13b04_devErlang/OTP
* gc/hipe_darwin_amd64: Fix hipe memory allocation problems on darwin/amd64 Porting x86 darwin fixes to amd64 darwin hipe asm/m4 code Automatically enable hipe for darwin/amd64 builds Allow configure to enable_hipe for darwin/amd64 builds OTP-8416 HiPE now works in the 64-bit emulator on Mac OS X. (Thanks to Geoff Cant.)

2010-02-08OTP-8323 Cross compilation improvements and other build systemRickard Green
improvements. Most notable: Lots of cross compilation improvements. The old cross compilation support was more or less non-existing as well as broken. Please, note that the cross compilation support should still be considered as experimental. Also note that old cross compilation configurations cannot be used without modifications. For more information on cross compiling Erlang/OTP see the $ERL_TOP/xcomp/README file. Support for staged install using <url href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">D ESTDIR</url>. The old broken INSTALL_PREFIX has also been fixed. For more information see the $ERL_TOP/README file. Documentation of the release target of the top Makefile. For more information see the $ERL_TOP/README file. make install now by default creates relative symbolic links instead of absolute ones. For more information see the $ERL_TOP/README file. $ERL_TOP/configure --help=recursive now works and prints help for all applications with configure scripts. Doing make install, or make release directly after make all no longer triggers miscellaneous rebuilds. Existing bootstrap system is now used when doing make install, or make release without a preceding make all. The crypto and ssl applications use the same runtime library path when dynamically linking against libssl.so and libcrypto.so. The runtime library search path has also been extended. The configure scripts of erl_interface and odbc now search for thread libraries and thread library quirks the same way as erts do. The configure script of the odbc application now also looks for odbc libraries in lib64 and lib/64 directories when building on a 64-bit system. The config.h.in file in the erl_interface application is now automatically generated in instead of statically updated which reduces the risk of configure tests without any effect.

2010-01-19OTP-8373 ERTS makefiles used to detect the use of a gcc C compiler byRickard Green
checking if CC equaled gcc. That is, the makefiles failed to detect gcc C compilers with other command line names than gcc. `configure' now substitute GCC into the makefiles. If CC is a gcc C compiler, GCC will have the value yes. (Thanks to Jean-S�bastien P�dron)
2010-01-12Merge branch 'tc/premodern-fpe' into ccase/r13b04_devErlang/OTP
* tc/premodern-fpe: Add -D_XOPEN_SOURCE to CPPFLAGS on Darwin platforms Test for reliable fpes on Darwin platforms without DARWIN_MODERN_MCONTEXT OTP-8368 The configure test for reliable floating point exceptions has been update to work on modern versions of Mac OS X. (Thanks to Trannie Carter.)
2009-12-18Add -D_XOPEN_SOURCE to CPPFLAGS on Darwin platformsTrannie Carter
ucontext routines are deprecated in Snow Leopard and defining _XOPEN_SOURCE is the suggested remedy.
2009-12-18Test for reliable fpes on Darwin platforms without DARWIN_MODERN_MCONTEXTTrannie Carter
The mcontext_t structure changed between Tiger & Leopard and the erts configure script doesn't take this into account when testing for reliable floating point exceptions. HiPE is not enabled when reliable fpes are not detected. The PPC test preserves the pre-modern mcontext_t and so builds on Tiger, but I suspect that PPC/Leopard is broken. I don't have the header files to check modern PPC mcontext_t so I haven't changed that part of the test.
2009-12-11OTP-8323 Miscellaneous cross compilation improvements. For example, oneRickard Green
new mandatory configuration variable that replaces all other previously mandatory configuration variables, and better documentation. Note that old cross compilation configurations cannot be used without modifications. For more information see the $ERL_TOP/xcomp/README file.
