No, you aren't, however, the problem of this benchmark are the inserted fwaits which are necessary to get fpu exceptions at correct lines.

It just means exactly what Peter stated - one needs to use exported sources (obtained using "svn export") rather than svn checkout. Note that this can be done even locally when having checked out sources.

If I get it right, one is supposed to have CYGWIN for win32 anyway: FP IDE absolutely doesn't run without it (it's bad, because, for example, running two applications using different CYGWIN libraries simultaneously makes fail at least one of them and so on). CYGWIN includes these UNIX style thingies (pwd.exe, cp.exe etc.). So that's it (if CYGWIN binaries directory is in the search path). I compile 2.1.x with this batch file: d: cd \fpc ren lastd _lastd // compiled compiler, previous build ren tmpsrc _tmpsrc // exported sources of the previous build cd fpcSVN // local repository svn update // updating repository svn export . d:\fpc\tmpsrc // exporting sources, if I mess with local repository, I run "svn cleanup" to remove junk cd ..\tmpsrc // exported sources, first make will produce (not so) junk here d:\fpc\2.0.4.rc2\bin\i386-win32\make clean all FPC=d:\fpc\2.0.4.rc2\bin\i386-win32\ppc386.exe // running some other make may be bad, and I still use 2.0.4rc2 for no reason, d:\fpc\2.0.4.rc2\bin\i386-win32\make install INSTALL_PREFIX=d:/fpc/lastd FPC=d:\fpc\tmpsrc\compiler\ppc386.exe // now there must be all native FPC files in d:\fpc\lastd\ (and FP IDE won't run without some tuning) And "make" uses d:\cygwin\bin\ utilities heavily. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

You don't need cygwin, we provide all the require unix tools. The makefiles even don't work in cygwin. They can only be run from the CMD prompt. That the FP IDE requires the cygwin1.dll is simply because the mingw32 gdb was not working. If you can remove the dependency on gdb for debugging you are welcome to provide patches. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
