I've been mostly successful with both Boost 1.37 and 1.38 but know of
three issues. Here's the first, which I found in a web search after
encountering problems trying to build, which seems to be a bug in Boost:
Furthermore building pyrap with boost-1.37 and gcc-4.3.2 gave an error
due to a missing include. The following patch has to be applied to
boost:
Index: boost/python/detail/translate_exception.hpp
===================================================================
--- boost/python/detail/translate_exception.hpp (revision 50228)
+++ boost/python/detail/translate_exception.hpp (working copy)
@@ -9,6 +9,7 @@
# include <boost/call_traits.hpp>
# include <boost/type_traits/add_const.hpp>
+# include <boost/type_traits/add_reference.hpp>
# include <boost/function/function0.hpp>
--------------------------------------
Here's the second issue:
You also need the threadpool resource:
sourceforge.net/projects/threadpool.
If you are using the 1_35_0 Boost libraries, you can use version
0.2.4 which
is included in the package (in dependencies). If you use a different
version
of the Boost libraries, you need to get an appropriate threadpool
version and
replace the files in "dependencies/threadpool/include". Copy into
the include
directory the contents of the boost directory in the threadpool package,
which includes a directory named "include" and a file "threadpool.hpp".
And the third, which I haven't yet figured out. After building Visual 5
on Ubuntu and Windows, I find that numpy.int32 is not recognized as an
integer that can be converted when needed as a double. For example,
vector(int,double,double) is okay, but vector(numpy.int32,double,double)
fails. This can occur if a vector argument comes from the use of arange,
and it causes several standard VPython example programs to fail. I've
been trying to install a manual converter using Boost, but have failed
so far due to lack of adequate knowledge of Boost.
