I'm trying to get node.js to compile. Unfortunately MacOS doesn't put g++ and
gcc in your path even if you install the developer tools, apparently, so I have
to stick them in there:
export SDK=/Developer/SDKs/MacOSX10.5.sdk
export PATH=/Developer/usr/bin:$PATH
But given that, `./configure` still fails. The log says it can't find
`pthread.h`.
The answer
----------
The rest of this document is about how I searched for the answer (although for
only three hours, because on MacOS, things Just Work!). The actual answer is
quite short.
tar xzvf node-v0.4.2.tar.gz
cd node-v0.4.2
export PATH=/Developer/usr/bin:$PATH
ISYSROOT="-isysroot /Developer/SDKs/MacOSX10.5.sdk"
export LINKFLAGS=$ISYSROOT CXXFLAGS=$ISYSROOT CFLAGS=$ISYSROOT
./configure --prefix=$HOME --without-ssl
make
Note that it is important to have the environment variables set for *both*
`./configure` and `make`.
Isn't MacOS wonderful? None of those obscure error messages you're used to from
Linux, and you can download almost any piece of open-source software, compile
it, and it works!
A false trail: `C_INCLUDE_PATH`, etc.:
--------------------------------------
Well, there's a perfectly good `pthread.h` in
`/Developer/SDKs/MacOSX10.5.sdk/usr/include/pthread.h` and also in
`/Developer/SDKs/MacOSX10.4u.sdk/usr/include/pthread.h`. It's not obvious why
the gcc from the developer package wouldn't find it. But it doesn't, so I gave
it a little bit of help (this was the wrong thing to do):
export C_INCLUDE_PATH=$SDK/usr/include
export CPLUS_INCLUDE_PATH=$SDK/usr/include
export LIBRARY_PATH=$SDK/usr/lib
That allows `./configure --without-ssl` to complete successfully, even though
it was the wrong thing to do. However, `make` still fails to build anything,
because it still can't find header files:

different error, which suggests that scons or make or something is removing my

If I unset those variables by hand, I get the same error messages SCons does.
Anyway, I'm clearly doing something wrong in the way I'm invoking the compiler,
but I don’t know the right way. [Apple’s note “The GCC Compiler Collection on
Mac OS X”](http://developer.apple.com/tools/gcc_overview.html) does not help;
it does not even suggest that this might be a problem.
Searching for stuff like this, I found five-year-old [instructions on compiling
`perl`](http://search.cpan.org/~rjbs/perl-5.12.3/README.macosx) which recommend
passing hairy `ccflags` and `ldflags` to Perl's `Configure` script. Namely:
./Configure -Accflags="-nostdinc -B$SDK/usr/include/gcc \
-B$SDK/usr/lib/gcc -isystem$SDK/usr/include \
-F$SDK/System/Library/Frameworks" \
-Aldflags="-Wl,-syslibroot,$SDK" \
-de
Maybe I can get this to work for Node's configure script. Still, I can't shake
the feeling that I must be doing something wrong to run into these problems in
the first place.
I found [some other guy with the same
problem](http://serverfault.com/questions/244406/problems-building-nodejs-on-macos-snow-leopard)
but he seems to have given up on building his own binaries and just installing
prebuilt binaries using Homebrew.
[Some other
guy](http://paulsolt.com/2010/11/objective-cc-iphone-build-failures/) has the
string `-isysroot /Developer/SDKs/MacOSX10.5.sdk` in his gcc command line...
that seems to help:

/Users/kragen/Downloads/node-v0.4.2/deps/v8/src/accessors.cc
(completes without errors!)
Unfortunately, it was not clear to me how to get "waf", invoked by Node's
`./configure`, to add this to the `CXXFLAGS` and `CFLAGS`.
Advice from IRC
---------------
[21:59] <echosystm> if you want to get up and running quickly, you're
probably best off just running a linux vm or something
[22:00] <echosystm> the latest dev tools wont run on 10.5, as far as i am
aware
[22:00] <echosystm> and you'll probably need them to build node
A solution (?)

It appears that the `CFLAGS` setting took, but the `CXXFLAGS` setting ([for
Waf](http://code.google.com/p/waf/wiki/EnvironmentVariables)) was ignored.
Also, though, perhaps the two directories were configured in different ways; it
doesn't seem to be invoking `g++` as `/Developer/usr/bin/g++`, even though it
invoked `gcc` as `/Developer/usr/bin/gcc`.
Hmm, if I supply `CXXFLAGS` directly to `make` as well as to `configure`, I
seem to make further progress:
Black-Beauty:node-v0.4.2 kragen$ CXXFLAGS='-isysroot
/Developer/SDKs/MacOSX10.5.sdk' make
...
g++ -o obj/release/accessors.o -c -isysroot /Developer/SDKs/MacOSX10.5.sdk

...
This still bombs out at the end with a link command line, which complains:
ld: library not found for -lcrt1.10.5.o
...and the corresponding 3.5 kilobyte command line lacks `-isysroot`. Supplying
`LINKFLAGS` (**not** `LDFLAGS`) fixes that problem, **and we're done**:
Black-Beauty:node-v0.4.2 kragen$ LINKFLAGS='-isysroot
/Developer/SDKs/MacOSX10.5.sdk' CXXFLAGS='-isysroot

...

And `make install` works.
