Hi all, I am not able to install lme 4, can you kindly help me sort this out? My R version is 2024.09.0+375, see below for the warning/error

ld: library 'gfortran' not found

Hi @JDinAcademia -

The error message tells you the issue, which is you are missing a necessary library to compile the package (gfortran).

I'm guessing you're using a Mac (based on the paths), which if you are using Homebrew for package installation can be installed using brew install gcc

Best,
Randy

Your development environment is incomplete.

I would advise not to use Homebrew for this, but install the Xcode command line tools, and also the fortran compiler linked from Tools - R for Mac OS X - developer's page - GNU Fortan for Xcode which is the same compiler that CRAN uses to build R in the first place.

[JDinAcademia]

still the same error, after I installed gfortran (still telling me not found)

[JDinAcademia]

I have this installed already through the terminal, but still having the same issue

[Gabor]

Try uninstalling gfortran 8.2.x, that's not the version you need, probably.

Or maybe that's the one you need, and it is not installed.

2024.09.0+375 is your version of RStudio, not R. You have R 4.2, while the current version is 4.4. There are binary versions of lme4 and its dependencies on CRAN for R 4.4 ("release" version) and R 4.3 ("oldrel" version). Updating to a newer version of R would make life easier!

While I followed the instructions on the R for macOS site suggested by Gabor, I only compile source code when necessary, such as development versions of R packages.

thank you ! all solved!
