Build failure with GR 3.7.4 on Arch #23

Closed chrisnorthcott closed 10 years ago

chrisnorthcott commented 10 years ago

The current gr-baz git will not build giving a bunch of compilation errors in swig/. All dependencies are installed. All goes well up until compiling the swig wrapper stuff:

Changing

define SWIGCPY_SLICE_ARG(arg) ((PySliceObject *)arg)

to

define SWICGPY_SLICE_ARG(arg) ((PyObject *) arg)

in the named source file seems to let the build finish but the resulting blocks do not work in GR and cause early termination.

Running Arch rolling release, both gnuradio and gr-baz have been pulled down from git today.

chrisnorthcott commented 10 years ago

Well, I found the cause of this; Arch has both python3 and python2.7 installed (with 3.0 as the default) and cmake was selecting python3's headers whereas the generated files from swig will only build with 2.7.

Doing pacman -Rdd python as root, building both gnuradio and gr-baz from git, and then reinstalling the python package (pacman -S python) fixed the problem. Although through all this I seem to have broken gnuradio in the process so once I've finished rebuilding everything and tested this solution properly I will close this issue.

chrisnorthcott commented 10 years ago

Everything works fine with the fix above. Three days I've been trying to get gr-baz to build (primarily for the autocorrelation sink) and finally success!

Closing.
