[C++-sig] Re: MSVC6 problems upgrading to Version_1_31_0 tag

Fri Feb 6 20:30:04 CET 2004

Unfortunately I have to confirm that Boost.Python from the 1.31.0 release fails
to compile with Visual C++ 6. :( :( :(
I am extremely frustrated because I spent days and days recompiling the
RC_1_31_0 branch over and over again with many different compilers. I guess I
got exhausted because the release was pushed back all the time and VC6 dropped
off my radar at some point.

However, I am having NO problems compiling with Visual C++ 7.0 (.NET 2002) and
7.1 (.NET 2003) using our SCons-based build system. This includes compiling all
tests in boost/libs/python/test. I.e. any problems with these compilers must be
due to the compilation flags used. To see that flags that I am using look here:

http://cci.lbl.gov/cctbx_build/results/2004_01_20_2338/win2000_py23_build_log

I should mention that our VC7 is the poor-man's version without the optimizer.
But our VC7.1 is the full-blown version.

I don't know what to do about the VC6 failure. David?
Two comments:

- First of all a plea: please, please, please try the release candidates if you
want to be sure a release works on your platform. For a volunteer driven
development like Boost it is very difficult to ensure everything is healthy on
all platforms at all times. Especially if antiquated compilers are involved we
really depend on timely feedback.

- Maybe it is a wink from god: VC6 is a very sick compiler anyway. A much
better alternative is readily available (VC71). I personally believe that any
effort spent on supporting VC6 is a huge financial damage in the bigger
picture.
