Can't install URD due to TTR error on mac about urd

[farrellja]

Hi tsotnech,

I haven't encountered this problem myself. But, I can think of a few things you might try:

First, you could see whether you can install the package directly as a binary. Try either install.packages("TTR", type="binary") and see whether it works. Or alternatively, download the binary from the CRAN page directly and using install.packages("path\to\package", repos=NULL) and see whether that works.

Alternatively, it looks like you're installing on Mac OS X. Do you have the command line developer tools installed? If not, you might try installing them by typing xcode-select --install from Terminal. I believe they are required for the correct compilation of many packages, so that might help?

If not, currently, I am using R 3.4.1, destiny_2.6.2, TTR_0.23-2, and Mac OS 10.12.6 so those versions all work together.

Hope that helps; Best, Jeff

Hi Jeff,

Thanks a lot for the suggestions, I have Xcode and I read on TTF GitHub that it might need Fortran compiler on mac, so I installed it as well but didn't help.

However installing the binary package helped. when I was trying to install destiny, it asked me to update TTR and when I updated all, it gave exactly same error. So installing the binary and not updating the TTR was a solution. I could successfully install URD afterwards.

thanks again for your help,

Best,
Tsotne
