That one sets the specified fixed path and then exports it. Setting a fixed 
PATH by hand is typically a bad idea since it removes all existing entries - 
and the one you listed didn't even have gfortran on it. Exporting is another 
alternative if you want to set the PATH for all subsequent commands.

The line I sent just prepends the /opt/gfortran/bin to the PATH for the one R 
CMD command, but doesn't affect anything else. I would recommend reading a 
basic tutorial on unix shell if you really want to know more (actually a good 
idea if you ever want to use the Terminal and not kill your machine).

No, it is only valid for the current R session (and I don't know about RStudio 
- it's not R so sometimes R rules don't apply), that's why I said it's for the 
case where you run install.packages() in the R session.


Note that another alternative is to simply symlink gfortran to your 
/usr/local/bin since that is on the PATH on macOS by default, i.e., you only 
need to run this in the Terminal once (requires admin access):

sudo ln -sfn /opt/gfortran/bin/gfortran /usr/local/bin/gfortran

Simon

Hi, Simon:


  Thanks for this.  I have more questions:


On 7/6/23 4:52 PM, Simon Urbanek wrote:

In the shell:

PATH=/opt/gfortran/bin:$PATH R CMD INSTALL ...



	  Please excuse my ignorance, but I don't understand this.  I 
previously tried "PATH=/bin:/sbin:/user/bin:/user/sbin:/system/Library/ 
export PATH", recommended on a page associated with support.apple.com, 
as mentioned below.  That did not seem to work for me.



	  How is this different?  What did I do wrong before that this would 
fix?  [Or feel free to ignore this question:  My immediate problem seems

in R if using install.packages()

Sys.setenv(PATH=paste0("/opt/gfortran/bin:", Sys.getenv("PATH")))



	  If I set this in RStudio, will it affect what I do in "Terminal" on 
my Mac and vice versa?



	  This looks like a potentially similar thing to do from what I did. 
Is the effect of this different?  If so, how? [Again, please feel free

Hi, Peter et al.:

I think the cleanest way is to diddle the /etc/paths.d structure. I have

PeterDaardsiMac:R pd$ ls /etc/paths.d

/usr/local/gfortran/bin
PeterDaardsiMac:R pd$ cat /etc/paths

and the latter would want to be /opt/gfortran/bin for 12.2 (I still have 8.2 
for now).



	  I could not figure out how "to diddle the /etc/paths.d structure", 
but I was successful by appending "/opt/gfortran/bin" to etc/paths using 
"sudo vi etc/paths".  It didn't work immediately nor after I exited and 
restarted Terminal, but it did after I rebooted.



	  There's till a lot I do not understand about this. 
readLines('/etc/paths') now returns a character vector of length 8, with 
the last string being the one I appended. Meanwhile, "echo $PATH" at a 
prompt returned a path with 13 components with "/opt/gfortran/bin" being 
number 11, and 'Sys.getenv("PATH")' returned a path with 18 components, 
with "/opt/gfortran/bin" being number 12.



  Anyway, thanks again to Simon and Peter.


  Best Wishes,
  Spencer Graves



Two things to note:

1. The directories in paths.d/* are added to those in /etc/paths in 
alphabetical order, so careful with older versions in /usr/local/bin.

2. You (probably) need to logout and back in for the changes to take effect in 
your Terminal windows.

Alternatively, you can twiddle the shell startup files (~/.profile /etc/profile 
/etc/bashrc ) directly. The trouble I have with that, is that I never feel 
sure that I am doing it in the right place.

Re: [R-SIG-Mac] gfortran: command not found

[Spencer Graves]

1.  I need to apologize to Simon:  I failed to see his reply to the 
original post.  Then I found the instructions and installed 
gfortran-12.2-universal.pkg, as indicated there, but it still didn't work.



2.  I'm not finding clear instructions on how to update the path on 
macOS 11.7.8, which is the latest version available for my 2014 MacBook 
Pro with a 2.8 GHz Quad-Core Intel Core i7.  I found several pages with 
differing instructions.  I found one in "support.apple.com" that 
recommended something that didn't work.[2]



  Further suggestions?


  Thanks again very much.
  Spencer Graves


[2] "support.apple.com" recommended 
"PATH=/bin:/sbin:/user/bin:/user/sbin:/system/Library/ export PATH", 
then "env".  I did "env" to get the current path, than appended 
":/opt/gfortran/bin" to that and executed the revised 
"PATH=...:/opt/gfortran/bin export PATH".  However, when I checked with 
"env" again, the change was not displayed.  I rebooted with the same 
result.

The installer says:

The resulting compiler will live in /opt/gfortran and can be called with
/opt/gfortran/bin/gfortran

so it's advisable to have /opt/gfortran/bin on the PATH.

(Side note: the arm64 build of R uses the full path, but some people 
have been objecting to that since they wanted to use other compilers for 
the legacy Intel builds, but as I suspected that causes other issues, so 
I'll change that for the next release).


Cheers,
Simon

There may also be a PATH issue when upgrading to 4.3.x, /usr/local -> 
/opt/R/ Does gfortran 12.2 install to /opt/R/.../bin ?

AFACT he didn't say so, there was no response, just double-posting of the same 
question after is was answered.

The installer says:

The resulting compiler will live in /opt/gfortran and can be called with
/opt/gfortran/bin/gfortran

so it's advisable to have /opt/gfortran/bin on the PATH.

Re: [R-SIG-Mac] gfortran: command not found

[Spencer Graves]

Hi, Peter et al.:


On 7/6/23 6:45 AM, Peter Dalgaard wrote:

  The default install went to "/opt/gfortran", and gcc is in "/usr/bin".


  What should I do to fix this?


	  I downloaded and reinstalled "gfortran-12.2-universal.pkg". I did NOT 
see an option to install it anyplace else.



  Thanks,
  Spencer Graves

Re: [R-SIG-Mac] gfortran: command not found

AFAICT, Spencer followed the implied instructions and it still didn't work. 

There may also be a PATH issue when upgrading to 4.3.x, /usr/local -> 
/opt/R/ Does gfortran 12.2 install to /opt/R/.../bin ?
