GC does not detect R (Linux)

[holop...@gmail.com]

Hi Everyone,

On my Arch Linux computer,  GC v.3.4GC fails to detect R (R Studio detects it fine).

 

I tried to see in Rembed how the detection was done, but this is above my skill level..

If this helps, export returns no R-related environment variables.

Thanks!

Check of R is enabled in options since it gets disabled if R is not found the first time you run.

If that doesn't work (after a restart) then you will need to specify R home. In R studio console (bottom left) type:

> R.home

The returned result can be used in options to specify the R installation.

Hi Mark,

I'm running build 3950 on both windows and linux, per the Help/About GC menus. The options windoes seem different.

In the options window on linux, there is only one lign to be checked or unckecked ("warn unsaved activities"), whereas on windows you have 2 more: "enable API webservices" and "Enable R". At the botth, the last field is for the R Installation Directory on Windows, but for the "workout and videosync library".

I can see from the screencast you're on Gnome and therefore most likely linux, so one explanation is that I'm not pulling the right source files or build files?

Not sure what the problem is, this hasn't changed for a month or so.

Should look like this:

Make sure R is enabled before specifing an installation location (leave that blank).

If it doesn't find R (its in a non-standard location) then you will need to set it (above is my example on OSX).

Hi Mark - here is what I see in the options windows. Is it possible I don't have the most recent version?

You build your own?

You need to enable R in the builds (it is optional). You need to add:

DEFINES += GC_WANT_R


You will also need R_HOME set in the shell environment when building as qmake (via src.pro) invokes the R executable to set other settings for make. For example, on my MBP:

export R_HOME=/Library/Frameworks/R.framework/Resources

Yes, Arch Linux does not use debian packages.

I did:

export R_HOME=/usr/lib64/R
echo "DEFINES +=GC_WANT_R" >> gcconfig.pri

The build fails with:

RTool.o: In function `RTool::pageSize(SEXPREC*, SEXPREC*)':

Rtools seems to be a windows package? https://cran.r-project.org/bin/windows/Rtools/

I need to sign off until tomorrow, and will return to this then.

Many thanks for your help.

rtool is a global variable defined on main.cpp conditional to  GC_WANT_R, probably you need to force main.cpp recompilation or just make clean;qmake;make on src folder.

Thanks ! Passing "--always-make" to make to ignore timestamps did the trick.

Thanks again for the help.

I tend to do something like:

$ touch `grep -l GC_WANT_R src/*/*.{cpp,h}`

To update the timestamps on source that references the symbol.
