I want to have a static Universal binary lib of Boost. (Preferable the latest stable version, that is 1.43.0, or newer.)

I found many Google hits with similar problems and possible solutions. However, most of them seems outdated. Also none of them really worked.

Right now, I am trying

sudo ./bjam --toolset=darwin --link=static --threading=multi \
--architecture=combined --address-model=32_64 \
--macosx-version=10.4 --macosx-version-min=10.4 \
install

That compiles and install fine. However, the produced binaries seems broken.

az@ip245 47 (openlierox) %file /usr/local/lib/libboost_signals.a
/usr/local/lib/libboost_signals.a: current ar archive random library

az@ip245 49 (openlierox) %lipo -info  /usr/local/lib/libboost_signals.a
input file /usr/local/lib/libboost_signals.a is not a fat file
Non-fat file: /usr/local/lib/libboost_signals.a is architecture: x86_64

Edit: It seems that the command was wrong and I must remove the “–” for most options. So the command I am trying now (-a just means to rebuild all):

sudo ./bjam -a toolset=darwin link=static threading=multi \
architecture=combined address-model=32_64 \
macosx-version=10.4 macosx-version-min=10.4 \
install

However, this gives many strange errors (what I already had earlier), all like this:

darwin.compile.c++.pch bin.v2/libs/math/build/darwin-4.2.1/release/address-model-32_64/architecture-combined/link-static/macosx-version-min-10.4/macosx-version-10.4/threading-multi/../src/tr1/pch.hpp.gch

This could be another problem I have when building Universal binaries: http://stackoverflow.com/questions/2830931/g-on-macosx-doesnt-work-with-arch-ppc64

Solution:

I found the problem. It seems that the MacOSX 10.4 SDK is missing a bunch of symlinks for GCC 4.2.

Use this as a test case:
http://stackoverflow.com/questions/2830931/g-on-macosx-doesnt-work-with-arch-ppc64

It will report multiple errors with GCC 4.2 (missing C++ includes, missing C includes, missing libs). In all cases, you can just fix that by setting a symlink. Search in your SDK for the file and just set the symlink in the same way it is in the MacOSX 10.5 SDK.

After that, it all just worked.
