Hi, I get the following error installing Rgraphviz: R CMD INSTALL Rgraphviz * Installing *source* package 'Rgraphviz' ... ** libs gcc -I/usr/local/lib/R/include `dotneato-config --cflags` -I/usr/local/include -D__NO_MATH_INLINES -mieee-fp -Wall -fPIC -g -O2 -c Rgraphviz.c -o Rgraphviz.o In file included from Rgraphviz.c:1: common.h:21:22: gvconfig.h: No such file or directory In file included from /usr/local/include/graphviz/render.h:49, from common.h:22, from Rgraphviz.c:1: /usr/local/include/graphviz/macros.h:28:1: warning: "NEW" redefined In file included from common.h:13, from Rgraphviz.c:1: /usr/local/lib/R/include/Rdefines.h:129:1: warning: this is the location of the previous definition In file included from /usr/local/include/graphviz/types.h:11, from /usr/local/include/graphviz/render.h:51, from common.h:22, from Rgraphviz.c:1: /usr/local/include/graphviz/pathplan.h:11: warning: ignoring #pragma prototyped In file included from /usr/local/include/graphviz/pathplan.h:16, from /usr/local/include/graphviz/types.h:11, from /usr/local/include/graphviz/render.h:51, from common.h:22, from Rgraphviz.c:1: /usr/local/include/graphviz/pathgeom.h:11: warning: ignoring #pragma prototyped In file included from /usr/local/include/graphviz/render.h:52, from common.h:22, from Rgraphviz.c:1: /usr/local/include/graphviz/graph.h:11: warning: ignoring #pragma prototyped In file included from /usr/local/include/graphviz/render.h:55, from common.h:22, from Rgraphviz.c:1: /usr/local/include/graphviz/gvrender.h:12: warning: ignoring #pragma prototyped In file included from /usr/local/include/graphviz/gvrender.h:19, from /usr/local/include/graphviz/render.h:55, from common.h:22, from Rgraphviz.c:1: /usr/local/include/graphviz/gvrenderint.h:12: warning: ignoring #pragma prototyped In file included from common.h:23, from Rgraphviz.c:1: /usr/local/include/graphviz/graph.h:11: warning: ignoring #pragma prototyped In file included from common.h:26, from Rgraphviz.c:1: /usr/local/include/graphviz/adjust.h:11: warning: ignoring #pragma prototyped In file included from common.h:28, from Rgraphviz.c:1: /usr/local/include/graphviz/gvrender.h:12: warning: ignoring #pragma prototyped Rgraphviz.c: In function `Rgraphviz_init': Rgraphviz.c:80: `Info' undeclared (first use in this function) Rgraphviz.c:80: (Each undeclared identifier is reported only once Rgraphviz.c:80: for each function it appears in.)

Is this an oversight in the development version or something I forgot to configure on my system. I am using a fresh install of R-1.9.0 on RH linux 9.0 and I have graphviz-1.12 and Rgraphviz_1.3.22 Thanks Nicholas

This will depend on how you installed the graphviz package and how your system looks through libraries. A quick fix is to use the environment variable LD_LIBRARY_PATH to set the library path. Try something like # export LD_LIBRARY_PATH=/usr/lib/graphviz with the exact path depending on your graphviz install. This is followed by installing Rgraphviz from the same shell. -- Kasper Daniel Hansen, Research Assistant Department of Biostatistics, University of Copenhagen

I am using a fresh install of R-1.9.0 > on RH linux 9.0 and I have graphviz-1.12 > and Rgraphviz_1.3.22 There was a slight change between Graphviz 1.12 and 1.11, and I'll be committing a change in the next few minutes so that Rgraphviz works against 1.12. At the same time, I'm going to modify the language of the SystemsRequirements field to say that it requires "Graphviz version 1.12" and not use the ">=" as that often turns out to not be true. Graphviz version 1.12 will be the version that the BioC 1.4 Rgraphviz will be using. When 1.4 is released, the Rgraphviz in the devel branch at that point will be working against Graphviz 1.13. -J
