gnuradio failed to build on 10.11

[girving]

brew install gnuradio is failing for me, and I'm not sure if it's a problem with gnuradio itself or cmake or both. Here's the result of brew gist-logs gnuradio: https://gist.github.com/girving/c180157b19c51ca28014

I think the problem is the bunch of errors of form

CMake Error at /usr/local/Cellar/cmake/3.4.0/share/cmake/Modules/FindPythonLibs.cmake:181 (get_filename_component):
  get_filename_component called with incorrect number of arguments

I'm not sure of that though; there are a lot of those errors and the build continues past all of them.

Just to confirm its not only you: Same problem here.
My brew gist logs here: https://gist.github.com/b140d77527b03aaf312e

Hmm, weird: I tried to find the commit that introduced the error by bisecting.
I started with 5ca6013 being the first known bad and with the "last know good" commit being 4e8756c.

Then I bisected my way all the way back to 5ca6013 (which was bad at the beginning).
But now it magically works, no build problems anymore o_O

Did I do something wrong? I am not sure whether git bisecting works correctly with brew.
I noticed that brew never downloaded any of the tar.gz ("Already downloaded") during the whole process. Though I used "brew cleanup" after every bisect step.
Maybe it just built an older version that worked. But I would expect that then the SHA check would fail which is given in the Formula.

Do you have python installed?

[MikeMcQuaid]

(with Homebrew or elsewhere beyond the system version)?

Hello this is one of errors

Here should be whole Homebrew/gnuradio/05.cmake
Over23/gnuradio_compile_debbug#1

I'm too green to give advices, but I have seen that Gnuradio is brewing python as dependency; in't it better than just to create direct dependency to just brewed version?

Having the same issue here. I'm trying to install gnuradio on a fresh install of OSX 10.11 and newest version of Xcode(not an upgraded version). Gist is here.

I'm hoping its not related to this post about Xcode 7.1 not supporting Qt4.

Has anyone gotten gnuradio to install on 10.11?

Same issue here. The following appears several times in the 05.cmake file.

CMake Error at /usr/local/Cellar/cmake/3.4.0/share/cmake/Modules/FindPythonLibs.cmake:181 (get_filename_component):
get_filename_component called with incorrect number of arguments
Call Stack (most recent call first):
cmake/Modules/GrSwig.cmake:149 (find_package) gnuradio-runtime/swig/CMakeLists.txt:50 (GR_SWIG_MAKE)

OS X 10.11.1, Xcode 7.1.1

I was able to fix this on my OSX 10.11.1 machine.

My gnuradio install failed with the get_filename_component called with incorrect number of arguments errors when I had cmake 3.4.0 installed, so I downgraded to cmake 3.3.2 and was able to compile.

It seems the very recent cmake 3.4 release affected that function: https://cmake.org/cmake/help/v3.4/release/3.4.html

[1ncorrect]

I tried installing an older version of cmake using homebrew, but for some reason building gnuradio with homebrew refused to recognise it.

Rather than waste any more time trying to figure out how to roll back a package within homebrew, I'd rather fix gnuradio 3.7.8 to build using cmake 3.4.0 or later, but I have no idea where to begin. Is this a bug in cmake or do we need to add/remove an argument to whatever is calling get_filename_component ?

[nejohnson2]

Agreed...and likewise, I have no Idea where to begin.

I can also say that I did reformat my machine, installed Xcode and cmake 3.1 via homebrew and tried gnuradio via homebrew (while removing the cmake => :build from the formula) but it failed. Not sure how to install cmake 3.3 as it's not listed in brew search cmake.

Regardless, I agree better to fix the cmake bug that to rely on an older version.

Thanks to Flushot's hint, I successfully solved this problem. Followings are what I did (not sure :-))
0. Install but disable new cmake
brew install cmake; brew unlink cmake

1. Install old cmake
   cd /usr/local/Library; git log | less
   // the last commit before cmake 3.4.0 was 0036e3d....
   git checkout -b cmake 0036e3d1.... // back to the past
   brew install cmake; brew switch cmake 3.3.2 // just for sure
2. install new gnuradio
   git checkout -b master // return to the current
   brew install gnuradio
   That's it. I hope this memo may help someone.
