Dear all,
hunting around for a while with plain VMware images and rebuilding
everything constantly I drilled down to the cause of the problem which I
reported earlier which turns out to be twofold:
1) osgDB::fopen is opening a file (fopen) in the scope of osgDB dll and
various plugins and also osgWidgets close files via the ANSI-C fclose
(in the scope of the plugin) - this works fine for most OSes just not
Windows and OS X. My fix is to inline the proxied version of fopen
because otherwise osgDB needs to provide the whole set of C file
operation functions.
2) Visual Studio 2008 is defaulting to link to the lowest common
denominator of the runtime which is something like 9.0.22*** - however
all known versions of VS 2008 (with or without SP or FeaturePack) ship
with a redistributable with version 9.0.30*** - thus welcome to SxS
hell. The introduced defines should work on both VS 2008 with and
without SP1 (there was a bug ignoring the catch all version _VC_LIBS_) -
it should have only an effect in VS 2005 and 2008 - maybe there should
be an CMake option() around the defines as I could imagine some people
want this exact behaviour.
Please test and comment (the patch is against the 2.8 branch but should
be easy to port into the trunk)
Cheers,
Hartmut
