Jason G:
Okay that's great Heinz, I have many questions about the FFTW build attempts (both Orcas & 2005). I may have to build this under vs2005 (with or without ICC). I have had to stop my g++ build three times because it used up my whole machine for too long. How long did the 100+ .C files take to build, on what kind of machine? do you still have the build log?

Did you choose many options in config.h? Were they selected for DLL or static lib., single float, single threaded or was that in VS2005 settings or both? Are these the correct ones for seti? (been with Intel libraries until now) Under the MingW g++ build i was able to run the configure script so it chose those for me for the most part, there are still some I am not sure about...

And may have to try a build in VS2005 because ir's too heavy load for my poor little old machine :( ... strangely the vs2005+ICC seti builds were rather quickly complete and relativelly trouble free.

Hi Jason,
1. I´m using a P4 2.66 MHZ no SSE3 1GB RAM
2. I need to compile the bench+fftwf under 2 minutes with Orcas
3. The buildprotokoll are atteched file fftw_SSE_build_prot.7z
4. Configuration Type : Static Library (.lib)
Whole Program Optimization : Use Link Time Code Generation
5. bench
5.1 Preprocessor Definitions: WIN32;NDEBUG;_CONSOLE;FFTW_SINGLE;BENCHFFT_SINGLE;HAVE_SSE
5.2 Codegeneration ---> Runtime Library : Multi-threaded (/MT)
5.3 Don´t forget to add the necessary "Additional Library Directories" in the Linker Section of bench´

I set a break at seti_header.cpp line 251
251 buffer += buf;
after the break buffer shows
