Hi Peter,
Unfortunately neither of the modifications to the LIB flag worked. I tried:
export CAIRO_LIBS='-L${HOME}/usr/local/lib -lcairo'
This actually gave me an error like this:
.....
configure: CAIRO_CFLAGS=-I/home/fong/usr/local/include/cairo
checking if R was compiled with the RConn patch... no
checking cairo.h usability... yes
checking cairo.h presence... yes
checking for cairo.h... yes
checking for PNG support in Cairo... yes
checking for ATS font support in Cairo... no
configure: CAIRO_LIBS=-L${HOME}/usr/local/lib -lcairo
checking for library containing deflate... none required
checking whether Cairo programs can be compiled... yes
checking whether cairo_image_surface_get_format is declared... no
checking for FreeType support in cairo... yes
checking whether FreeType needs additional flags... yes
checking whether pkg-config knows about fontconfig or freetype2... yes
checking whether additional flags work... no
configure: error: Cannot use cairo-ft backend, although cairo claims it is
working. Please check your caito installation and/or update cairo if
necessary or set CAIRO_CFLAGS/CAIRO_LIBS accordingly.
ERROR: configuration failed for package 'Cairo'
* removing '/home/fong/usr/local/lib64/R/library/Cairo'
* restoring previous '/home/fong/usr/local/lib64/R/library/Cairo'
I then tried to modify the CAIRO_LIBS like this:
export CAIRO_LIBS=-I${HOME}/usr/local/lib/libcairo.so
And this gave me this error:
.....
configure: CAIRO_CFLAGS=-I/home/fong/usr/local/include/cairo
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=-I/home/fong/usr/local/lib/libcairo.so
checking for library containing deflate... no
checking whether Cairo programs can be compiled... configure: error: Cannot
compile a simple Cairo program. See config.log for details.
ERROR: configuration failed for package 'Cairo'
* removing '/home/fong/usr/local/lib64/R/library/Cairo'
* restoring previous '/home/fong/usr/local/lib64/R/library/Cairo'
My pkg-config command:
>> pkg-config --cflags --libs cairo -I/home/fong/usr/local/include/cairo
-I/home/fong/usr/local/include/pixman-1
-I/home/fong/usr/local/include/freetype2
-I/home/fong/usr/local/include/libpng16 -L/home/fong/usr/local/lib -lcairo
I appear to be missing glib and libdrm which you have. Perhaps I should try
to install that?
Thanks,
