I know I know another Rgraphviz loading problem. But in case someone has already seen this and has a quick answer. I am running a fully patched version of Ubuntu 8.04 with R.10.0. I am having difficulty getting Rgraphviz to work. I compiled graphviz from source using versions 2.2, 2.22.2, and 2.24.0. All versions compiled fine. Once installed Graphviz-2.2 did not work correctly, dot loads but running any commands in dot causes a segmentation fault. Both 2.22.2 and 2.24.0 work in dot as expected returning results from the example code. I have used the Rgraphviz source code for BioC 2.5 version 1.24.0. Rgraphviz compiled correctly using each version of graphviz with the following line R CMD INSTALL --configure-args='--with-graphviz=/usr/local' "/mnt/hgfs/db/R-based manual analyses/customPackages/Rgraphviz_1.24.0.tar.gz" However when I run R and try to load the library I get the following error message: > library(Rgraphviz) Loading required package: graph Loading required package: grid Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared library '/home/fjsim/R/x86_64-pc-linux-gnu- library/2.10/Rgraphviz/libs/Rgraphviz.so' : /usr/local/lib/libgvc.so.5: undefined symbol: agputs Error: package/namespace load failed for 'Rgraphviz' I get the same error using either graphviz 2.22.2 or 2.24.0. Strangely enough when 2.2 is installed, and Rgraphviz compiled it is able to load the Rgraphviz library but R crashes when a call is made to layoutGraph just as when I try to run commands via dot directly. My conclusion is that 2.2 is not compatible with my version of Ubuntu as it's too old and Rgraphviz does not like the new versions of graphviz (just as in windows). Any help? I also tried a Google search for "undefined symbol agputs" and didn't get any results.

Hi, Sim I think the Rgraphviz error is Graphviz installation failure. Some files relative to Graphviz are not there. You might be able to get helps at Graphviz or Ubuntu mailing list about this issue. But I think one option is switching your ubuntu 8.04 to 9.04 or 9.10. Graphviz and Rgraphviz work very well on both platform, even the Remix version.
