@jeroenooms Thanks for the instructions. I have installed the poppler-cpp library and specified the LD_LIBRARY_PATH and PKG_CONFIG_PATH.
The LD_LIBRARY folder contains the libpoppler-cpp.* files and pkgconfig folder contains the *.pc files. Up on restarting RStudio server and trying to install 'pdftools' package, I get the following error:
** package ‘pdftools’ successfully unpacked and MD5 sums checked
Package poppler-cpp was not found in the pkg-config search path.
Perhaps you should add the directory containing `poppler-cpp.pc'
to the PKG_CONFIG_PATH environment variable
No package 'poppler-cpp' found
Using PKG_CFLAGS=-I/usr/include/poppler/cpp -I/usr/include/poppler
------------------------- ANTICONF ERROR ---------------------------
Configuration failed because poppler-cpp was not found. Try installing:
* deb: libpoppler-cpp-dev (Debian, Ubuntu, etc)
* rpm: poppler-cpp-devel (Fedora, CentOS, RHEL)
* csw: poppler_dev (Solaris)
* brew: poppler (Mac OSX)
If poppler-cpp is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a poppler-cpp.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...
I do not have a 'cpp' folder in /usr/local/include path. Any suggestions?
