Dear useRs,
I have several problems in using rgl-0.77 (and recent earlier
versions) on Gentoo Linux with a custom-built v. 2.6.22 kernel.
Currently I use R-2.6.1.
When I build rgl,
# R CMD INSTALL "/home/liviu/inst/dwn/R/rgl_0.77.tar.gz"
or
install.packages("rgl", dependencies=TRUE, method ="wget"),
I notice the following warning messages:
i686-pc-linux-gnu-g++ -I/usr/lib/R/include -I/usr/lib/R/include
-I/usr/local/include -fpic -O2 -march=pentium-m -pipe
-fomit-frame-pointer -std=gnu99 -c api.cpp -o api.o
cc1plus: warning: command line option "-std=gnu99" is valid for C/ObjC
but not for C++
The warning message itself is repeated during the entire build
process. However, the package builds fine, but fails to load:
> library(rgl)
Error in dyn.load(file, ...) :
unable to load shared library '/usr/lib/R/library/rgl/libs/rgl.so':
/usr/lib/R/library/rgl/libs/rgl.so: undefined symbol: glTexCoordPointer
Error : .onLoad failed in 'loadNamespace' for 'rgl'
Error: package/namespace load failed for 'rgl'
I had the exact same error message with rgl_0.76.
Could anyone suggest how to make rgl build correctly?
Liviu
