It's working! 1) I added the #include "block.h" line 2) I set an environment variable MACI64 to 0 (as recommended in the help file you linked) 3) I started matlab from the shell using: matlab -maci Thanks so much! Emily |

Emily, I managed to get rid of this error "'MP_Block_c' was not declared in this scope" by including :#include "block.h" in the block_factory.h file. It seems that this file cannot be reached by the compiler. For the second problem, i am actually using Matlab R2009a which is with maci configuration. If errors keep happening, i suggest you to get this one while i am updating mine to see what's happening. I've also founded an interesting help if you're interested: http://www.mathworks.de/matlabcentral/newsreader/view_thread/262164 |

Update: I successfully built and ran mpd from the command line without BUILD_MATLAB_MEX_FILES but with CMAKE_OSX_ARCHITECTURES set to i386. So I believe the fftw-3.2.2 and libsndfile-1.0.21 libraries are working fine using 32 bits, even given the error that I got for libsndfile. So the only thing holding me up is building the mex files. |

Thanks, Ronan -- I think I'm much closer to getting it to work now, but I'm still having a couple of issues: 1) I needed to recompile fftw-3.2.2 and libsndfile-1.0.21 for a 32 bit architecture. fftw worked fine using: ./configure --with-gcc-arch=i386 but I'm having trouble with libsndfile. I'm using: ./configure --build=i386-apple-darwin10.3.0 then when I run make, it gives me the error: ld: warning: in ../src/.libs/libsndfile.dylib, file was built for i386 which is not the architecture being linked (x86_64) but it also generates a libsndfile.a and libsndfile.la -- should I use one of these in the cmake parameter setup? 2) When I run cmake on mptk (given the error in libsndfile), I get errors that don't seem to be a result of the libsndfile issue. I have CMAKE_OSX_ARCHITECTURES set to i386, and the make runs as far as running 'CMake Rules', and then it crashes with a bunch of errors starting with: "'MP_Block_c' was not declared in this scope" Looking at the output, I think the issue is related to the way mexopts.sh is being used, because it looks like it still uses the x86_64 architecture in the CXX Flags and it points to a nonexistent maci64 directory: -> mexopts.sh sourced from directory (DIR = $MATLAB/bin) FILE = /Applications/MATLAB_R2009b.app/bin/mexopts.sh ---------------------------------------------------------------- -> MATLAB = /Applications/MATLAB_R2009b.app -> CC = gcc-4.0 -> CC flags: CFLAGS = -fno-common -no-cpp-precomp -arch x86_64 -isysroot /Developer/SDKs/MacOSX10.6.sdk -mmacosx-version-min=10.5 -fexceptions CDEBUGFLAGS = -g COPTIMFLAGS = -O2 -DNDEBUG CLIBS = -L/Applications/MATLAB_R2009b.app/bin/maci64 -lmx -lmex -lmat -lstdc++ arguments = -DHAVE_FFTW3 -DMX_COMPAT_32 -> CXX = g++-4.0 -> CXX flags: CXXFLAGS = -fno-common -no-cpp-precomp -fexceptions -arch x86_64 -isysroot /Developer/SDKs/MacOSX10.6.sdk -mmacosx-version-min=10.5 CXXDEBUGFLAGS = -g CXXOPTIMFLAGS = -O2 -DNDEBUG CXXLIBS = -L/Applications/MATLAB_R2009b.app/bin/maci64 -lmx -lmex -lmat -lstdc++ arguments = -DHAVE_FFTW3 -DMX_COMPAT_32 -> FC = gfortran -> FC flags: FFLAGS = -fexceptions -m64 -fbackslash FDEBUGFLAGS = -g FOPTIMFLAGS = -O FLIBS = -L/Applications/MATLAB_R2009b.app/bin/maci64 -lmx -lmex -lmat -L -lgfortran -L -lgfortranbegin arguments = -DHAVE_FFTW3 -DMX_COMPAT_32 -> LD = gcc-4.0 -> Link flags: LDFLAGS = -Wl,-twolevel_namespace -undefined error -arch x86_64 -Wl,-syslibroot,/Developer/SDKs/MacOSX10.6.sdk -mmacosx-version-min=10.5 -bundle -Wl,-exported_symbols_list,/Applications/MATLAB_R2009b.app/extern/lib/maci64/mexFunction.map LDDEBUGFLAGS = -g LDOPTIMFLAGS = -O LDEXTENSION = .mexmaci64 arguments = -L/Users/Emily/Documents/BU/2010_Spring/MA751/Final_Project/MPTK/lib/Release -lmptk -lmptk4matlab -> LDCXX = -> Link flags: LDCXXFLAGS = LDCXXDEBUGFLAGS = LDCXXOPTIMFLAGS = LDCXXEXTENSION = arguments = -L/Users/Emily/Documents/BU/2010_Spring/MA751/Final_Project/MPTK/lib/Release -lmptk -lmptk4matlab ---------------------------------------------------------------- I'm guessing it's pointing to the maci64 section of mexopts.sh rather than the maci section. Any idea what needs to change? Thanks, Emily |

Hi Emily, There are few tricks that i can give you: 1) I suggest you to use the latest version of Cmake (2.8.1) because i recently had problems with olders versions of Cmake which didn't took in account the CMAKE_OSX_ARCHITECTURES, as default setting for gcc version 4.2.1 is now x86_64. 2) What is the ccmake value of CMAKE_OSX_ARCHITECTURES? Because in fact, if this is empty, the default value is setting to x86_64. So set it to i386. 3) When you does a "ls -ll" command terminal for "c++" and "gcc" under /usr/bin, if the symbolic link is to "c++-4.x" and "gcc-4.x" versions beyond 4.2.0, the MEX compilation won't work because the earliest gcc version supported with mex is "4.0.0". The latest version tested for use with mex is "4.2.0". So i suggest you to change it using ln command in order to have a symbolic link with "c++-4.0" and "gcc-4.0" Cheers Ronan |

| I think the issue is that I'm running a 32-bit Matlab on a 64-bit machine. Is there a way to trick it into generating 32-bit maci files? | |

Hi, I've managed to install and use the command-line interface using BUILD_EXECUTABLE and BUILD_SHARED_LIBS, but when I add on BUILD_MATLAB_MEX_FILES I get an error. The Matlab variables are set to: MATLAB_ENG_LIBRARY=/Applications/MATLAB_R2009b.app/bin/maci/libeng.dylib MATLAB_INCLUDE_DIR=/Applications/MATLAB_R2009b.app/extern/include MATLAB_MEX_LIBRARY=/Applications/MATLAB_R2009b.app/bin/maci/libmex.dylib MATLAB_MX_LIBRARY=/Applications/MATLAB_R2009b.app/bin/maci/libmx.dylib MEX_COMPILER=/Applications/MATLAB_R2009b.app/bin/mex The error I'm getting is when I run make, and I think the important lines are: ld: warning: in /Applications/MATLAB_R2009b.app/bin/maci/libmex.dylib, file was built for i386 which is not the architecture being linked (x86_64) ld: warning: in /Applications/MATLAB_R2009b.app/bin/maci/libmx.dylib, file was built for i386 which is not the architecture being linked (x86_64) ld: warning: in /Applications/MATLAB_R2009b.app/bin/maci/libeng.dylib, file was built for i386 which is not the architecture being linked (x86_64) ld: warning: in /Applications/MATLAB_R2009b.app/bin/maci/libmex.dylib, file was built for i386 which is not the architecture being linked (x86_64) ld: warning: in /Applications/MATLAB_R2009b.app/bin/maci/libmx.dylib, file was built for i386 which is not the architecture being linked (x86_64) ld: warning: in /Applications/MATLAB_R2009b.app/bin/maci/libeng.dylib, file was built for i386 which is not the architecture being linked (x86_64) I've attached the entire output in case that's helpful. |
