[R-SIG-Mac] Compiling Cairo

[O'Hanlon, Simon J]

Dear Simon,
Thanks for the fast reply. I did not compile R from source. Also I was
trying to compile Cairo myself because if I used the pre-built binary from
CRAN I get the error: "Failed to create Cairo backend!² when trying to use
the postscript device.

I completely removed all Homebrew packages and Homebrew itself. I also
removed X11 using this gist:
https://gist.github.com/TonyMtz/714e73ccb79e21c4fc9c.

I then removed any installations I had made of the libraries cario,
freetype and pixman using sudo make uninstall.

I tried to install Cairo from source again and unsurprisingly it could not
compile because no working installation of cairo or it¹s dependencies
could be found. Great! I then reinstalled Homebrew and cairo, pkg-config,
and X11 (via Homebrew) and their various dependencies.

I realised that pkg-config was not looking in the right place for my
installed libraries so I set the correct path using:

    Sys.setnev( 
PKG_CONFIG_PATH="/usr/local/lib/pkgconfig:/opt/X11/lib/pkgconfig²)

I then get the following output from the configure script which seems to
indicate I am now entirely compiling against Homebrew installed packages
(I think - sorry, I am relatively inexperienced at this):

    checking for pkg-config... /usr/local/bin/pkg-config
checking whether pkg-config knows about cairo... yes
checking for configurable backends... cairo cairo-ft cairo-pdf cairo-png
cairo-ps cairo-xlib cairo-xlib-xrender
configure: CAIRO_CFLAGS=-I/usr/local/Cellar/cairo/1.14.2/include/cairo
-I/usr/local/Cellar/glib/2.44.0/include/glib-2.0
-I/usr/local/Cellar/glib/2.44.0/lib/glib-2.0/include
-I/usr/local/opt/gettext/include
-I/usr/local/Cellar/pixman/0.32.6/include/pixman-1
-I/usr/local/Cellar/fontconfig/2.11.1/include
-I/usr/local/Cellar/freetype/2.5.3_1/include/freetype2
-I/usr/local/Cellar/freetype/2.5.5/include/freetype2
-I/usr/local/Cellar/libpng/1.6.16/include/libpng16 -I/opt/X11/include
checking if R was compiled with the RConn patch... no
checking cairo.h usability... yes
checking cairo.h presence... yes
checking for cairo.h... yes
checking for PNG support in Cairo... yes
checking for ATS font support in Cairo... no
configure: CAIRO_LIBS=-L/usr/local/Cellar/freetype/2.5.5/lib
-L/usr/local/Cellar/libpng/1.6.16/lib -L/usr/local/Cellar/cairo/1.14.2/lib
-L/opt/X11/lib -lfreetype -lz -lpng16 -lz -lcairo -lXext -lXrender -lX11


However, the exact same error persists. I also tried to compile using
gcc-4.9 rather than clang, but same difference. So would your
recommendation would be to attempt to compile R myself?

Many thanks,

Simon
