c++ - Compiler Error: Undefined symbols for architecture x86_64 (Mac OS X 10.10.4; GLM) -

-

i have implemented new class sceneobject raytracer project. in project i'm using glm lib tasks.

now i'm getting the: undefined symbols architecture x86_64 error when try compile.

my compiler:

 ✘ arneosterthun@arnes-air  ~/documents/studium/programmiersprachen/raytracer/build   sceneobject ●  gcc -v using built-in specs. collect_gcc=gcc collect_lto_wrapper=/usr/local/libexec/gcc/x86_64-apple-darwin14.0.0/4.9.2/lto-wrapper target: x86_64-apple-darwin14.0.0 configured with: ../gcc-4.9-20141029/configure --enable-languages=c++,fortran thread model: posix gcc version 4.9.2 20141029 (prerelease) (gcc)   arneosterthun@arnes-air  ~/documents/studium/programmiersprachen/raytracer/build   sceneobject ●  make -v gnu make 3.81 copyright (c) 2006  free software foundation, inc. free software; see source copying conditions. there no warranty; not merchantability or fitness particular purpose.  program built i386-apple-darwin11.3.0

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
