Re: [Boost-users] boost exceptions on MacOS 10.5

Lothar,
1.34.0?

You should upgrade to 1.34.1 and just try it. 1.34.1 replaced 1.34.0 July
2007.

IIRCl 1.34.0 could not build universal binaries and I was quite frustrated.

Thanks to some hard work by someone on the Boost project, they fixed that
for 1.34.1 as far as I can tell.

I built my current copy of the Boost Libraries from the sources for
1.34.1using the standard build process. I did not do anything special:
.configure; make; sudo make install;

The usual.

Daniel

Some people building C++/Obj-C code on OS X with Xcode and who have a
problem think: "I know, I'll use the Boost Libraries". Now they have two
problems--three if they used Boost for regular expressions. ;-)
