Archived issue #0017418
Specific generation of project files is needed for MS VC++ 2005
Description
Currently OCCT comes with project files generated by WOK tools for MS VC++ 7.1
(VS .NET 2003)
When using MS VC++ 8.0 compiler (VS 2005), it becomes necessary to convert
these projects in new format. Though this is made automatically by MS VS, this
is inconvenient and (by default) produces projects that are not guaranteed to
have the desired options.
For instance, in VC++ 7.1 option /Op (disable floating point optimizations) is
OFF by default. In VC++ 8.0, default is /fp:precise which is equivalent to /Op
being ON in VC++ 7.1. This leads to 1.5-2 times performance degradation of the
programs converted to VC++ 8.0. The right way to preserve the same options is
to set option /fp:fast in VC++ 8.0
