[PD] problems with building flext with mingw

Hi list,      Just an fyi and question about building flext on winxp using mingw:   from build.txt: "Please be aware that the build system might have difficulties handling paths with spaces."   Unclear whether this statement only applies to the directory in which you are building flext or everything including your installation of pd.  If it is the latter then this is confused by the fact that config-win-pd-mingw seems to point by default to %ProgramFiles%\pd which is guaranteed to have spaces in it.   also from buildsys\config-win-pd-mingw:   # path to pthreads headers (PD comes with some in the src folder)   as far as I can tell this simply isn't true except for an old branch of pd where the header file no longer even exists.  But the bigger problem is that mingw itself doesn't come with support for pthreads.  However, there is a third party library here:   http://sourceware.org/pthreads-win32/    Unfortunately when I a) put the pthread.h header file in path-to-pd\include, and b) put the executable + library files in path-to-pd\ I get errors at the end of the compilation that it can't find _imp__* (below).  If I set LDFLAGS to -static then I still get an error that it can't find -lpd at the very end.   I don't see any other options in the notes or build instructions.   Downloaded flext using: svn co https://svn.grrrr.org/ext/trunk/flext flext   This is with 0.43.4-extended-20130111.   -Jonathan   d"/src -I"%ProgramFiles%/pd"/include -I"%ProgramFiles%/pd"/include/pd source/fll ib.cpp -o pd-mingw\release-shared\fllib.opp g++ -c -msse -mfpmath=sse
