I am puzzled by this entire thread.
The other day, at home, at my Mac running Yosemite with the newest
shiniest Xcode tools installed,
I did something like this...
cd /tmp/
svn co https://github.com/wocommunity/wonder.git/trunk/Utilities/
Adaptors
cd /tmp/Adaptors
gnumake
gnumake Apache2.4
and that built me the module; copying stuff by hand was not onerous.
There were some gotchas. On OSX, the project is set up to build the
WO adaptor internals (this works), the CGI adaptor (this works), the
FastCGI adaptor (does not work, missing headers) and the Apache2.2
adaptor (never got there because of FastCGI; didn't care). The
project will build the Apache 2.4 adaptor, provided the WO adaptor
internals have been built.
/usr/sbin/apxs will not work as-is: it tries to use a compiler
toolchain that doesn't exist, referring to IIRC /Applications/
Xcode.app/Contents/Developer/Toolchains/OSX10.10.xctoolchain/usr/bin/
cc . apxs is your friend; it's there to let you build Apache modules
with the same compiler and flags (especially optimisation flags) as
was used to build Apache.
So we do something like (from memory)
cd /Applications/Xcode.app/Contents/Developer/Toolchains/
OSX10.10.xctoolchain/
sudo ln -s XcodeDefault.xctoolchain OSX10.10.xctoolchain
and if I have that right, we can now use Xcode tools via the same
filenames as were used by whoever at Apple built Apache 2.4 for
Yosemite. Have a read of the /usr/sbin/apxs script. Even if (like
me) you don't code in perl, you should find yourself looking at /usr/
share/httpd/build/config_vars.mk next, which will have the reference
to /Applications/Xcode.app/Contents/Developer/Toolchains/
OSX10.10.xctoolchain/usr/bin/cc , and you will also see no
optimisation flags listed in CFLAGS -- personally, here I would
remove -O2 from CFLAGS in all the Makefiles that build any code
loaded by Apache.
In an ideal world, those of us interested in Apache only would rework
this project to avoid invoking the compiler or linker directly, we'd
have apxs do it for us, noting we can still get at some settings as
'apxs -q CFLAGS', 'apxs -q CC' etc.
You will also likely need to remove any '-macosx_version_min 10.5'
compiler/linker arguments because the recent OSX C compilers don't
appear to support that any more.
