I get the same issue installing the binary, but building from source seems to work OK:

brew install poppler
brew install pkg-config

and then in R

install.packages('pdftools', type='source')

[jeroen]

Thanks. It seems the cran builder by default builds against xquartz. So the immediate fix is to install xquartz.

For the next version I'll change the configuration to avoid this dependency!

[jeroen]

I submitted a new version to cran pdftools 1.7 which should no longer depend on XQuartz.

I have the same problem ! thank you david14142 :) :)

[jeroen]

@jira0325 which version of pdftools do you use? This problem should be fixed.

[jira0325]

@jeroen version 2.1
