Re: [Discuss-gnuradio] gnuradio on osx 10.6.4

Hi Michael,

                       I noticed something weird, and was wondering if you've come across this already 

when using qt-4.7 cocoa 32-bit only, qwt, qwtplot3d, sip and pyqt4, and building gnuradio, the linker incorrectly attempts to link to the Carbon libraries, 

h ../../../libtool --tag=CXX   --mode=link g++ -g -O1 -Wno-strict-aliasing -Wno-parentheses  -D_THREAD_SAFE   -module -avoid-version    -o _qtgui.la -rpath /usr/local/lib/python2.6/site-packages/gnuradio/qtgui _qtgui_la-qtgui.lo -lstdc++ libgnuradio-qtgui.la 

libtool: link: g++ -Wl,-undefined -Wl,dynamic_lookup -o .libs/_qtgui.so -bundle  .libs/_qtgui_la-qtgui.o   ./.libs/libgnuradio-qtgui.dylib -L/usr/local/lib -L/Developer/Applications/Qt-4.7/lib /Users/elvis/Tool/gnuradio/gnuradio-core/src/lib/.libs/libgnuradio-core.dylib /Users/elvis/Tool/gnuradio/gruel/src/lib/.libs/libgruel.dylib -lboost_thread /usr/local/lib/libfftw3f.dylib /usr/local/lib/libgsl.dylib /usr/local/lib/libgslcblas.dylib -lcblas -lstdc++ -lqwt -lqwtplot3d -lz -lm  -Wl,-dylib_file -Wl,/usr/local/lib/libgnuradio-core-3.4git.0.dylib:/Users/elvis/Tool/gnuradio/gnuradio-core/src/lib/.libs/libgnuradio-core.dylib -Wl,-dylib_file -Wl,/usr/local/lib/libgruel-3.4git.0.dylib:/Users/elvis/Tool/gnuradio/gruel/src/lib/.libs/libgruel.dylib -Wl,-dylib_file -Wl,/usr/local/lib/libgruel-3.4git.0.dylib:/Users/elvis/Tool/gnuradio/gruel/src/lib/.libs/libgruel.dylib   -framework QtOpenGL -framework QtGui -framework QtCore -framework AppKit -framework Carbon -framework OpenGL -framework AGL -framework ApplicationServices

However, prior to the build, gnuradio configure correctly detects qwt headers

checking /usr/local/include/qwt/qwt.h usability... yes

checking /usr/local/include/qwt/qwt.h presence... yes

checking for /usr/local/include/qwt/qwt.h... yes

checking for main in -lqwt... yes

checking /usr/local/include/qwtplot3d/qwt3d_plot.h usability... yes

checking /usr/local/include/qwtplot3d/qwt3d_plot.h presence... yes

checking for /usr/local/include/qwtplot3d/qwt3d_plot.h... yes

checking for main in -lqwtplot3d-qt4... no

checking for main in -lqwtplot3d... yes

Now, thinking perhaps carbon was needed somehow, I rebuilt  qt-4.7, qwt, qwtplot3d, sip and pyqt4 using carbon 32-bit only, but this time around it doesn't detect the qwt headers !! 

checking /usr/local/include/qwt/qwt.h usability... no

checking /usr/local/include/qwt/qwt.h presence... no

checking for /usr/local/include/qwt/qwt.h... no

Could not find qwt headers

Best regards,
