OS X: detect clang and build for x86 target only.

2014-03-20T21:26:24+00:00

Newer versions of Xcode / OS X don't support PPC code anymore and replace gcc
with clang. When clang is detected assume we want to build for the default
architecture only and change the minimum OS X version to 10.5.

Fix rm function on Windows once more.

2014-01-05T16:08:50+00:00

Windows del doesn't handle a non-existing folder gracefully, so check for
existence first.

Fix rm function on Windows.

2014-01-05T16:05:11+00:00

Windows del doesn't handle paths with / as separators, need to convert them
first.

Fix rebuilding of libs on OS X.

2014-01-05T15:55:23+00:00

OS X ar operates on fat libaries. In this case updating the library isn't
possible and when those change ar will only return an error. Remove the output
file prior to running ar to work around this limitation.

Move LDOPTS to the end of the linker call.

2013-11-12T21:51:59+00:00

Command line order is important with newer gcc versions. mkzenboot extends
LDOPTS but the linker would ignore that since no object using it has been
mentioned on the command line. Moving it to the end should fix this.

Treat arch flags separately when building libraries.

2013-06-09T17:43:37+00:00

On OS X we're passing -arch twice which dependency generation doesn't like.
Since we don't have dependencies that differ between architectures simply don't
add them during dependency generation.

Implement dependency generation in libtools.make.

2013-05-11T18:34:12+00:00

Automatically generate dependency files for all sources so changes in headers
are picked up automatically. Use one dependency file for each source file,
since that allows to create them without using external tools (except the
compiler of course).

Change mkdir -p to work on Windows.

2013-05-11T18:34:12+00:00

Windows mkdir doesn't know about the -p option and requires paths to use \ as
path separator. Try to detect when building on Windows and use the Windows
internal function instead of relying on a compatible mkdir in the path.

Make libtools compile rule more generic.

2013-05-11T18:34:11+00:00

Create the object - source dependency internally and use a more generic rule
for compiling. Removes the need for explicit rules for source files located in
a different folder.

This adds the limitation for SOURCES and LIBSOURCES to only hold C files.

Set APPVERSION globally for extralibs Makefile.

2013-05-10T15:48:01+00:00

Make sure its value quotes are properly escaped. Otherwise make on Windows
causes problems. Also, expand CPPDEFINES only once.
