Data.table: Error when installing from source on macOS

[jrf1111]

I've followed all the instructions on https://github.com/Rdatatable/data.table/wiki/Installation and searched StackOverflow, but I cannot get data.table to install from source (for OpenMP support) on Mac 10.14.6 with R4.0. I keep getting this error when I try to install from source:

Are you able to try gcc instead of clang?

Just spotted this recently
https://github.com/s-u/R-mac-dev
Haven't look at it because I don't have mac, but maybe it will be helpful

[jrf1111]

Sorry, I'm kinda a newbie at this. How would I go about using gcc instead?

[jrf1111]

Never mind. I figured it out and am able to install with multithreaded support. I had to change my .R/Makevars file. Here are the new contents:

@jrf1111 thanks for providing solution, closing then

[eacabbi]

Sorry to bother but I am trying to decipher the solution as I have the same problem (yes, newbie)

In which way having llvm and using other C compilers (not the ones in llvm, which give that strange error in the first post to me too) solves the problem? In case I do not have that gfortran, but I have actually followed all the instructuons https://github.com/Rdatatable/data.table/wiki/Installation#openmp-enabled-compiler-for-mac but with manual installation, what should I write in Makevars to have data.table running multi-thread?

[eacabbi]

I have switched to gfortran per https://mac.r-project.org/tools/, https://cran.r-project.org/bin/macosx/tools/, set up .R/Makevars like this

FLIBS=-L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin18/8.2.0 -L/usr/local/gfortran/lib -lgfortran -lquadmath -lm

The CRAN version works but with single thread. There is a stackoverflow thread about this https://stackoverflow.com/questions/59658131/error-package-or-namespace-load-failed-for-data-table-in-library-dynamlib-p which provides no useful answer.

[jrf1111]

You may need to use gfortran version 6.3.0 available here: https://github.com/fxcoudert/gfortran-for-macOS/releases/tag/6.3

[jrf1111]

Make sure to update your Makevars file too.
FLIBS=-L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin16/6.3.0 -L/usr/local/gfortran/lib -lgfortran -lquadmath -lm

[eacabbi]

Sadly, no. The problem persists with both gfortran 6.3.0 and 8.2.0

[jrf1111]

Did you remove the prior install of data.table? And did you install the CRAN version instead of the developer version?

[eacabbi]

Yes, I sure did. I tried with all of them and same result: the error with the developer version, successful installation but single thread with CRAN (Thanks for trying to help!)

[jrf1111]

It looks like there are still a few differences between your Makevars file and mine. Try just replacing your entire Makevars file with what I used:

[eacabbi]

restarted, followed your advice, it works now. Thanks!!!

[jrf1111]

Glad I could help!

[likanzhan]

Following the above suggestions, I got the following errors

[1] "en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8"
Error: package or namespace load failed for ‘data.table’ in library.dynam(lib, package, package.lib):

Any suggestions?

[jangorecki]

@likanzhan looks to be a different issue then, please create new issue and put all the input and output of attempting to install in newly started R session.

The solution below worked for me:

Never mind. I figured it out and am able to install with multithreaded support. I had to change my .R/Makevars file. Here are the new contents:

[daynefiler]

@jangorecki It would be helpful to update the Makevars file on the installation wiki -- thank you to you and the Rdatatable team!

[eacabbi]

For what matters, I had to reinstall from scratch for Catalina. I found out that llvm still does not work, whereas setting the .Makevars with gfortran compilers (as above, but also for version 8.2.0) does the trick.

Never managed to get through the compilation with llvm, both in Mojave and Catalina.

[FarMar]

I am also having this issue, using both the .R/Makevars file suggested on the readme page (which reports the standard error at the bottom of that page, and led me here), and with @daynefiler's code above. That generates this output:

Installing using the usual install.packages("data.table") works, but results in the multicore issue this fix is trying to address

[jangorecki]

@FarMar could you check if install.packages("data.table", type="source") works for you? Looks like your compiler is incorrectly defined in Makevars.

[FarMar]

@jangorecki That works with the Makevar file removed, but throws the "no OpenMP error", same as the CRAN repo. It fails with the Makevars file detailed by @jrf1111 and in @daynefiler's replies above

[jangorecki]

@FarMar Before trying to compile data.table with custom Makevars, please ensure it does compile anything. By anything I mean a package with compiled code. Otherwise the problem is not really related to data.table code. Once your compiler can compile anything, then there might a data.table problem when compilation fails.

1. If you want to follow path of this thread, you probably need to install missing software, or configure paths, so Makevars from here will be specyfing compiler correctly.

2. Otherwise you can roll back to the point where your compiler works, then try to follow https://github.com/Rdatatable/data.table/wiki/Installation wiki, and then when it fails, open new issue with your Makevars and output.

In both cases you need to ensure compilation works on anything.
To check that you can try to install any package with compiled code. I have a "hello world from C" toy package that should be sufficient

install.packages("r.gitlab.ci", repos="https://jangorecki.gitlab.io/r.gitlab.ci")

when installing package from CRAN you need to add type="source" because CRAN has mac binaries, which by default will be used, rather than package sources.

[MichaelChirico]

@FarMar note this line of your installation output

/usr/local/gfortran/bin/gcc: No such file or directory

That means your machine is configured to look for gcc at that path: /usr/local/gfortran/bin/gcc

You can check if that file exists on your machine. I have gcc there on Mac (but unfortunately I am not fully sure how it got there, hopefully the Installation wiki).

Personally I am using llvm on Mac at /usr/local/opt/llvm which I set up from the Installation wiki.

In either case, it should be defined as CC in your ~/.R/Makevars.

Hope that helps.

[FarMar]

Otherwise you can roll back to the point where your compiler works, then try to follow https://github.com/Rdatatable/data.table/wiki/Installation wiki, and then when it fails, open new issue with your Makevars and output.

@jangorecki I'm going to head down that route. I seem to break compiling from the first Markevars edit in your readme. I couldn't compile your test with the custom Makevars present, works fine without.

[klkeys]

hello everybody -- thanks for this thread! I followed the directions for a macOS installation using a llvm install from brew, but couldn't get this package installed with

install.packages("data.table", type = "source", repos = "https://Rdatatable.gitlab.io/data.table")

compilation always failed with this error:

Error: package or namespace load failed for ‘data.table’ in library.dynam(lib, package, package.lib):
 shared object ‘datatable.so’ not found

after some headbanging on my keyboard, I found that this warning proved pretty helpful:

in my case, locate did not work. I tried locate zlib.h zconf.h and got

WARNING: The locate database (/var/db/locate.database) does not exist.
To create the database, run the following command:

  sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist

my machine is almost new, so perhaps that's why I got this message. at any rate, I ran that launchctl load command and waited a few minutes, after which locate could find several places where zlib.h and zconf.h were located on my system. with that in place, a source installation worked like a charm.

SUMMARY: might be overkill, but what worked for me was to perform these brew installations before installing data.table from source:

brew update
brew install llvm pkg-config zlib gettext

then build the database for locate:

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist

and use the ~/.R/Makevars file from the installation page with an extra C++ compiler flag for zlib:

LLVM_LOC = /usr/local/opt/llvm
CC=$(LLVM_LOC)/bin/clang -fopenmp
CXX=$(LLVM_LOC)/bin/clang++ -fopenmp
# -O3 should be faster than -O2 (default) level optimisation ..

CPPFLAGS=-I/usr/local/opt/gettext/include -I$(LLVM_LOC)/include -I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include -I/usr/local/opt/zlib/include

hopefully this can save somebody future headache!
