When compiling media-sound/rezound-0.12.3_beta-r1 I got these error messages: ... checking fftw.h usability... yes checking fftw.h presence... yes checking for fftw.h... yes checking for fftw_create_plan in -lfftw... yes checking rfftw.h usability... no checking rfftw.h presence... no checking for rfftw.h... no configure: WARNING: ***** rfftw.h (version 2) header file not found -- any FFT based actions will be disabled (http://www.fftw.org) ***** ... i686-pc-linux-gnu-g++ -DHAVE_CONFIG_H -I. -I. -I../../config -I../../src/misc -I../../src/misc/missing/generated -I../../src/PoolFile -march=prescott -O2 -ggdb -g -Wall -Wno-unused-function -Wno-unused-variable -Wno-unused -I/usr/include -I/usr/include -I/usr/include -MT FilterActionDialogs.lo -MD -MP -MF .deps/FilterActionDialogs.Tpo -c FilterActionDialogs.cpp -o FilterActionDialogs.o i686-pc-linux-gnu-g++ -DHAVE_CONFIG_H -I. -I. -I../../config -I../../src/misc -I../../src/misc/missing/generated -I../../src/PoolFile -march=prescott -O2 -ggdb -g -Wall -Wno-unused-function -Wno-unused-variable -Wno-unused -I/usr/include -I/usr/include -I/usr/include -MT GenerateActionDialogs.lo -MD -MP -MF .deps/GenerateActionDialogs.Tpo -c GenerateActionDialogs.cpp -o GenerateActionDialogs.o FilterActionDialogs.cpp: In member function ‘virtual double CActionParamMapper_arbitraryFIRFilter_kernelLength::interpretValue(double)’: FilterActionDialogs.cpp:212: error: ‘TFFTConvolverTimeDomainKernel’ was not declared in this scope FilterActionDialogs.cpp:212: error: expected primary-expression before ‘float’ FilterActionDialogs.cpp:212: error: expected `;' before ‘float’ FilterActionDialogs.cpp: In member function ‘virtual double CActionParamMapper_arbitraryFIRFilter_kernelLength::uninterpretValue(double)’: FilterActionDialogs.cpp:221: error: ‘TFFTConvolverTimeDomainKernel’ was not declared in this scope FilterActionDialogs.cpp:221: error: expected primary-expression before ‘float’ FilterActionDialogs.cpp:221: error: expected `;' before ‘float’ make[2]: *** [FilterActionDialogs.lo] Error 1 make[2]: *** Waiting for unfinished jobs....

Replies suggest updating fftw, but on my system, I had all the latest fftw versions installed: [I] sci-libs/fftw (2.1.5-r3(2.1)@04/03/08 3.1.2(3.0)@04/03/08) Neither of them does provide an rfftw.h, only srfftw.h and drfftw.h. Looking at the fftw-2.1.5-r3.ebuild, I found that there were some symlinks for these files in CVS version 1.6 which had not been present in the 1.5 version I had installed. Indeed, after remerging fftw, rezound compiled just fine. So a simple workaround for this issue is "emerge -1 =sci-libs/fftw-2*". As these changes affect not only the compile time behaviour of fftw, but also the set of installed files (resp. symlinks), there should be a revision bump. rezound might even be changed to block the -r3 revision, to force portage to update fftw first and compile rezound against a fixed version afterwards. That would reliably get rid of above error messages.
Just bumped in cvs. Thanks for catching this.
