Hi all

In trying to install the ggtree package, I encountered a problem with one of its dependencies: fftwtools.

Thanks for your help!

Dear Maarten,

the output of your sessionInfo indicates that you are running R under OS X Sierra, but attempt to install packages from sources. Is there any particular reason why you don't use mac binaries? Platform-specific binary packages typically include the necessary dependencies, so you should be able to install fftwtools with

install.packages("fftwtools", type="mac.binary.el-capitan")

If you still want to compile from sources, you could first install the fftw system library from the command line

brew install fftw

and then run install.packages("fftwtools").

Cheers,

Andrzej

It has an operating system dependency, on the libfftw3 library; you'll have install (the 'devel' version) of it. On my linux machine this is sudo apt-get install libfftw3-dev.
