Spidermonkey build failure (undefined symbols) with non-default build_arch

[breaker.dave@…]

The spidermonkey port on 32bit OS X 10.6/32bit firmware fails.

macports.conf settings are:

build_arch                      i386

# machine architectures
universal_archs        i386

Please remember to preview and use WikiFormatting, and cc the maintainer.

Please show the output of sysctl hw.cpu64bit_capable. BTW, although it likely has nothing to do with this problem, setting universal_archs to a single arch makes no sense.

At this stage we are just tring to get a 32bit version of our in house app ported from Linux to OSX. It relies on Xerces, Xalan and Spidermonkey. From reading the Macports documentation we thought that by setting the architecture to i386 we would only get 32-bit binaries of the libraries. Is this not correct?

hw.cpu64bit_capable
hw.cpu64bit_capable: 1

Model Name: Mac Pro
Model Identifier: MacPro1,1
Processor Name: Dual-Core Intel Xeon
Processor Speed: 3 GHz
Number Of Processors: 2
Total Number Of Cores: 4
L2 Cache (per processor): 4 MB

Bus Speed: 1.33 GHz
Boot ROM Version: MP11.005C.B08
SMC Version (system): 1.7f10

[jmroot (Joshua Root)]

Setting 'build_arch i386' is the correct way to get macports to build for i386, yes. The important thing here is that you are on an x86_64 machine, which means 10.6's gcc produces x86_64 binaries by default. This is a bug, but not the bug you initially described.

Marcus fixed spidermonkey so it respects build_arch in r63295.
