Building fails on OS X

With newest node-libpd, node.js and installing v8 through homebrew sh build-macos.sh returns:

This probably means I should compile libpd myself for i386, could you give me any pointers did you just do make?

[thisconnect]

I got some help of a friend, to recap this is my setup nodejs v0.8.20 and v8 installed with homebrew. libpd from upstream https://github.com/libpd/libpd compiled with make.

Could this be the conflict?

file /usr/local/lib/libv8.dylib
/usr/local/lib/libv8.dylib: Mach-O dynamically linked shared library i386

file libpd/libs/libpd.dylib
libs/libpd.dylib: Mach-O universal binary with 2 architectures
libs/libpd.dylib (for architecture x86_64): Mach-O 64-bit dynamically linked shared library x86_64
libs/libpd.dylib (for architecture i386):   Mach-O dynamically linked shared library i386

Note my self compiled libpd is a universal binary with x86_64 and i386

Yeah having a 32 bit version of libv8 will be a problem. I have a similar configuration to you where I installed libv8 and node using homebrew and built libpd from source.

$ file /usr/local/lib/libv8.dylib
/usr/local/lib/libv8.dylib: Mach-O 64-bit dynamically linked shared library x86_64

$ v8
V8 version 3.15.11 [sample shell]

$ node -v
v0.8.16

You could try reinstalling libv8 using --universal to see if there is a universal binary for v8.

$ brew uninstall v8
$ brew install v8 --universal 

I must warn you that node-libpd builds on osx but segfaults running the simplest test. I haven't had time to figure out what I'm doing wrong with respect to string handling in v8. Either something changed or I relied on some behavior that wasn't 100% correct to start with. This project definitely needs some love to be very useful.

I just did the following, and ended up with the same x86_64 version of v8

$ brew uninstall v8
Uninstalling /usr/local/Cellar/v8/3.9.24...
$ brew install v8 --universal

Hope this helps you.
