[Visualpython-users] Help with Boost on Mac OS

[Hugh F. <hug...@an...>]

I'm just starting to fill in the stubs for my native Mac
OS Carbon version of VPython, which in turn seems to be
triggering previously hidden Boost errors. Things like
	bool check() const;
in boost/python/extract.hpp are being reported as errors
by Xcode 'doesn't declare anything'

I downloaded the Boost 1_34_1 sources and bjam, did a
bjam build and then bjam install. If that wasn't enough,
I have absolutely no idea how to proceed.

Can anybody point me to either a nice prebuilt installer
for Boost on MacOS, or at least some detailed instructions
on pitfalls and how to avoid them?

Hi Hugh,

I haven't had a chance yet to work on the vpython/boost stuff, but I  
did get boost to build on Mac OS.

Finals are almost over, so I hope to jump in with you soon!

Can you compile the example program here:

http://www.boost.org/doc/libs/1_35_0/more/getting_started/unix- 
variants.html

It worked for me with the following command line:

c++ -I /usr/local/include/boost-1_34_1 example.cpp -o example

good luck!

You can install boost (versions between 1.32 to 1.35) via Fink.
Boost1.34 is used for building vpython (the released X11 version) with Fink.

Note in the CVS file MAC-OSX.txt (which is somewhat out of date) these 
comments, which may or may not be relevant to your problem:

Before making a change to src/Makefile.in, I got a message about 
possible mismatch of versions,
as though when I build against /sw/bin/python2.5 and then run 
/sw/bin/python2.5 the system thinks
these are different pythons. Martin Costabel commented:

"I am getting this, too, when using the dynamic boost-python library, 
but not with the static
libboost_python-mt.a. This is certainly a bug with the 
libboost_python-mt.dylib, but I haven't
yet found a combination of build flags to build it correctly, in 
particular in a way that would
also work on OSX 10.5."

Following his suggestion, I put Mac-specific code into src/Makefile.in 
to link to these other
libraries. But then I got this error message in the link phase of the make:

/usr/bin/ld: table of contents for archive: /sw/lib/libboost_python-mt.a 
is out of date; rerun ranlib(1) (can't load from it)

So I executed ranlib /sw/lib/libboost_python-mt.a, redid the make, 
executed make install, and it worked.

In the meantime, I found the right flags. The current Fink boost1.34 (or 
1.35) libraries work for me with vpython (3.2.9 or also 4beta24), using 
the dynamic library.

Hi Martin, Hugh, Bruce, etc...

Forgive me if I'm not thinking about this right... but for a new  
native/carbon build I'd think we'd want to steer clear of fink as  
much as possible. I got the impression we were trying to make a  
completely stand-alone vpython that doesn't require any fink, not  
even for libraries/etc...

I got boost to build OK in /usr/local/ with fink "turned off". I  
guess the next step is to try to get some of vpython to compile and  
link against those header files and libraries?

You can always repeat manually what Fink does. Most of a Fink package 
description is just a short documentation of the steps necessary to get 
the sources, patch them and build and install the package. You can use 
the experience and information contained in the package description to 
build things yourself.

Of course, this goes both ways: Once you manage to create an aqua 
version of vpython, I will probably try to make a Fink package of it, 
because I consider Fink also as a convenient all-purpose package 
manager. I consider typing a single command "fink install visual-py25" 
simpler than reading and following any instructions to download and 
install a package, even if it exists in the form of a dmg with 
precompiled binaries in it.

I'm sure that would work... however, I've had serious trouble with  
fink in the past where I didn't *realize* it was being used to  
resolve various dependencies and then someone without fink could not  
run an app I had built due to shared libraries being linked in  
without my knowledge! I guess I know just enough to be  
dangerous.. ;-). Anyway.. I guess I'd say we might use fink to sort  
out how to build something (e.g., boost) but it would be best, in the  
interest of building a truly stand-alone library, to avoid building  
with fink enabled (i.e., after running /sw/bin/init.sh). Of course..  
all IMVHO. ;-)
