Hi,
Eric, thanks for your help. I got a bit further by using
$ LIBRARY_PATH=<path_to_googletest_build> CPATH=<path_to_googletest_include> ./waf configure --boost-includes ... --boost-libs …
Two other dependencies then emerged, first gsl (which was straightforward to install with homebrew), and Qt - I used Qt4 from the anaconda python distribution and added the paths to the respective environment variables for the compiler.
However, now the dependency on librt is a real dealbreaker. Librt is not available on OSX. Going by the forums, this seems to be a rather common problem on OSX (and somehow linked to Qt), and it is often solved by simply not linking against rt, without loss of functionality (maybe some of the librt symbols are provided by some other standard lib on OSX).
Is there an easy way to skip the test for librt presence, and tell the linker not to link against librt? I assume that this means tweaking the build system. Unfortunately my waf skills are definitely underdeveloped, and I can’t figure out how to do this.
Any hints or ideas? Many thanks in advance :)
Best,
Michael
P.S.: By the way, why does Spikeyhal require Qt? Could Spikeyhal be built without it, without loss of core functionality?
