Install png on yosemite & RRO

[Enzo]

I have problems trying to install the png package from source.

I posted the problem on stackoverflow as I'm not convinced is a RRO issue but it seems more a yosemite issue.

I can install the compiled package with 

install.packages("png", repos="http://cran.us.r-project.org",type="mac.binary.mavericks" )

And it succeeds (but I do not have means to test it).

Any help is welcome though!

This is my post:

I am trying to install the package png on a macbookpro 2014 & yosemite.

I am using RRO (but I believe I would have a similar issue with R).

This is what I can see on the RRO console:

* installing *source* package ‘png’ ...

On the other hand I have installed (using homebrew) libpng and I can type libpng-config on the terminal having a response

Usage: /usr/local/bin/libpng-config [OPTION] ...

I am running out of options...

Additional info

I reverted to CRAN R and re-installed all my packages.  I noticed that mostly I installed binaries (while RRO tends to compile from source).

After the png binary installation I tried to re-install from source and it worked: mistery.

Hi Enzo,

That appears to be the issue -- for some reason, Revolution R Open is always insisting on building from source, but CRAN R is happy to install the binary. I'm not sure why yet, but we're looking into it. Thanks for reporting the issue. (If you like, you can track the followups here: https://github.com/RevolutionAnalytics/RRO/issues/32 )

The errors you saw are likely due to not having Xcode installed, which is required to build on a Mac. I have Xcode installed and don't see those errors.

In the meantime, you can force RRO to install the binary version with: install.packages("png", type="mac.binary.mavericks")

Cheers,

We have opened an issue at https://github.com/RevolutionAnalytics/RRO/issues/32

My understanding is that this has already been fixed in the build process, and will be available in RRO in the forthcoming update release.
