Sebastian, there is good news and bad news, and it is that I can't reproduce your failure, though I slightly changed the source code to incorporate the changes we've already discussed and to make the plugin less dependent on 'swh' plugins. Also, instead of _init, _fini I'm now using, as suggested by documentation on shared libraries, static void __attribute__ ((constructor)) my_init(void) static void __attribute__ ((destructor)) my_fini(void) Please find attached mbeq_119700.c.before_PerlPreProcessor.gz file - compare it with what you have if you wish. Please find below the protocol of my actions and please see that output file is generated, there is no segmentation fault, exit status is 0. Please pay attention to the following: Build commands: --------------- 1) \rm -r .PerlPreProcWS/ ; ./PerlPreProcessor -config_hash_file PerlPreProcessorConfigHash.c++.prl mbeq_119700.c.before_PerlPreProcessor > mbeq_119700.c 2) gcc -I/AppsFromScratchWD/install/fftw-3.1.2/include -DFFTW3 -O2 -msse -mfpmath=sse -fPIC -DPIC -g -c -Wall mbeq_119700.c -o mbeq_119700.o 3) gcc -lrt -lm /maxtor5/sergei/AppsFromScratchWD/install/fftw-3.1.2/lib/libfftw3f.so -shared mbeq_119700.o -Wl,-soname,mbeq_119700.so -o mbeq_119700.s . - please pay attention to -I/AppsFromScratchWD/install/fftw-3.1.2/include /maxtor5/sergei/AppsFromScratchWD/install/fftw-3.1.2/lib/libfftw3f.so items - I have locally built SSE-enabled FFTW3 library. The build commands are now much easier than they used to be. It is easy to build SSE-enabled FFTW3 library - download ftp://ftp.fftw.org/pub/fftw/fftw-3.1.2.tar.gz , unpackage the tarball, and run ./configure --prefix=/your/install/path --enable-shared --enable-float --enable-sse make make check make install The "/your/install/path" is, of course, moral equivalent of my "/maxtor5/sergei/AppsFromScratchWD/install". .
