R with png() support

Question

I am building R from source on Heroku via Vulcan, and trying to debug lack of png() support. I think the issue has to do with discovery of libXmu or equivalent, based on the below output. How do I pass the compiler a folder to look in for libXmu? (I can curl one down just fine).

checking X11/Intrinsic.h usability... yes
checking X11/Intrinsic.h presence... yes
checking for X11/Intrinsic.h... yes
checking for XtToolkitInitialize in -lXt... yes
using X11 ... yes
checking for KeySym... yes
checking X11/Xmu/Atoms.h usability... no
checking X11/Xmu/Atoms.h presence... no
checking for X11/Xmu/Atoms.h... no

Capabilities shows a lack of png and x11:

> capabilities()
    jpeg      png     tiff    tcltk      X11     aqua http/ftp  sockets 
   FALSE    FALSE    FALSE    FALSE    FALSE    FALSE     TRUE     TRUE 
  libxml     fifo   cledit    iconv      NLS  profmem    cairo 
    TRUE     TRUE     TRUE     TRUE     TRUE    FALSE    FALSE 

my kitchen sink make call:

./configure --prefix=$prefix --enable-R-shlib --with-x --with-libpng --with-jpeglib && make && make install

Answer 1

make sure you have X11 and cairo support installed, I have come across the same problem and fix by installing X11, Xt, Xmu libs and installing cairo
