Hi, I am Linux Ubuntu 9.04 user. I'm using R-2.6. Actually, I am developing R package for reading/writing 3D images. I needed to use the R package Rcpp in order to make profit of available C/C++ codes. My problem is that my C code is not able to include the Rcpp.h
In fact, when I run this command R CMD build rply, I got the following error message in the file /home/amine/R/r-eclipse/rply.Rcheck/00install.out: * Installing *source* package 'rply' ... ** libs gcc -std=gnu99 -I/usr/share/R/include -fpic -g -O2 -c Call_interface.c -o Call_interface.o gcc -std=gnu99 -I/usr/share/R/include -fpic -g -O2 -c C_interface.c -o C_interface.o gcc -std=gnu99 -I/usr/share/R/include -fpic -g -O2 -c fifrt.c -o fifrt.o g++ -I/usr/share/R/include -fpic -g -O2 -c RCPP_test.cpp -o RCPP_test.o RCPP_test.cpp:1:18: erreur: Rcpp.h : No such file or directory RCPP_test.cpp: In function ‘SEXPREC* readRIntVec(SEXPREC*)’: RCPP_test.cpp:14: erreur: ‘RcppVector’ was not declared in this scope RCPP_test.cpp:14: erreur: expected primary-expression before ‘int’ RCPP_test.cpp:14: erreur: expected `;' before ‘int’ make: *** [RCPP_test.o] Erreur 1 ERROR: compilation failed for package 'rply' ** Removing '/home/amine/R/r-eclipse/rply.Rcheck/rply' It is evident that I will this error since the file Rcpp.h is not in this directory /usr/share/R/include . I tried to solve this include problem by copying the Rcpp.h to /usr/share/R/include. But, it was not successful and I the following error message. Error in dyn.load(file, DLLpath = DLLpath, ...) : Unable to load shared library '/home/amine/R/r-eclipse/rply.Rcheck/rply/libs/rply.so': /home/amine/R/r-eclipse/rply.Rcheck/rply/libs/rply.so: undefined symbol: _ZN10RcppVectorIiEC1EP7SEXPREC Error in library(rply) : .First.lib has failed for 'rply' Execution stopped It looks like this package has a loading problem: see the messages for details. Resulting this last error seems to be also logical. In fact, I think the file libRcpp.so is need for the compilation of my code. Please notice that the package Rcpp is installed in the following directory: /usr/lib/R/site-library/Rcpp Thank you for giving an idea for solving this problem. -- View this message in context: http://n4.nabble.com/How-to-resolve-include-Rcpp-h-problems-tp962875p962875.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
