<DIV>I suspect it has to do with how we build for visual c++.</DIV>
<DIV>- It doesn't use pre-compiled header files</DIV>
<DIV>- It makes heavy use of templates.</DIV>
<DIV> </DIV>
<DIV>Doing either of those on code which was not originally developed in Visual studio using the "microsoft way" can lead to longer build times. I can't go into details about what the microsoft way is because it won't necessarily be compatible with Linux...so the resulting discussion would be moot. </DIV>
<DIV> </DIV>
<DIV>Actually, I think you'll also find that the runtime in DEBUG mode will also be excessive. MSVC8 added boundary checking in STL containers....which means that every single operator[] or operator* on iterators will result in quite a bit of code running and asserts being checked.</DIV>
<DIV> </DIV>
<DIV>This, of course, collapses in "release" mode, so the runtime is at least fast.</DIV>
<DIV> </DIV>
<DIV>What's basically happening is all the templates (which there are tons when using flopc++) get instantiated multiple times during compile and link. Fun eh?</DIV>
<DIV> </DIV>
<DIV>Sooo...strictly speaking it isn't "the compiler" since one could potentially get it faster...but at the price of making it difficult to use on Linux....</DIV>
<DIV> </DIV>
<DIV>Or I could be wrong.</DIV>

<DIV><BR>> Dear all, <BR>> <BR>> I'd like to ask a question about FlopC++ under Visual Studio. <BR>> When I build and run example "aircraft", which is part of Projectfile "FlopCpp" <BR>> (Folder \trunk\MSVisualStudio\v8\FlopCpp\), it takes a lot of time. It runs <BR>> fine, but building is very slow in compared to building under Linux. <BR>> Is it a problem of Visual Studio, that the code generation takes so much time? <BR>> <BR>> Thanks in advance, <BR>> <BR>> Christian <BR>> -------------- next part -------------- <BR>> An HTML attachment was scrubbed... <BR>> URL: <BR>> http://list.coin-or.org/pipermail/flopcpp/attachments/20061020/92ff87b6/attachme <BR>> nt-0001.html <BR>> <BR>> ------------------------------ <BR></DIV></body></html>
