I get the following trying to install gpclib package in R 3.6.2:

Package which is only available in source form, and may need compilation of C/C++/Fortran: ‘gpclib’ These will not be installed

I have already installed Rtools.

I tried with the code: 

install.packages("gpclib")

Trying with 

install.packages("gpclib", type="source")

the message is:

installing *source package 'gpclib' ...
** package 'gpclib' successfully unpacked and MD5 sums checked **
using staged installation ** libs *** arch - i386 Warning in system(cmd) :
'make' not found ERROR: compilation failed for package 'gpclib' *
removing 'C:/Users/Juan/Documents/R/win-library/3.6/gpclib'
Warning message: In install.packages("gpclib", type = "source") :
installation of package ‘gpclib’ had non-zero exit status*

  • Sound like you will need to compile the source then install it after compilation. – Slipoch Jan 20 '20 at 00:18

  • Thanks for the reply. I tried with the code: **install.packages("gpclib")**. Trying with **install.packages("gpclib", type="source")** the message is: *installing *source* package 'gpclib' ... ** package 'gpclib' successfully unpacked and MD5 sums checked ** using staged installation ** libs *** arch - i386 Warning in system(cmd) : 'make' not found ERROR: compilation failed for package 'gpclib' * removing 'C:/Users/Juan/Documents/R/win-library/3.6/gpclib' Warning message: In install.packages("gpclib", type = "source") : installation of package ‘gpclib’ had non-zero exit status* – jartm Jan 20 '20 at 00:49
  • try `install.packages("https://cran.r-project.org/src/contrib/gpclib_1.5-5.tar.gz", type="source", repos = NULL)` – user20650 Jan 20 '20 at 01:21
  • although the *make not found* does maybe suggest that rtools isnt being found?? – user20650 Jan 20 '20 at 01:32
