Rscript无法使用PHP exec（）加载ggplot2包，但它在shell中运行良好

Question

I have already installed ggplot2 and Rcpp package; these run well when I am using shell, but fail if using exec() PHP

here my error log:

Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared object '/usr/lib64/R/library/Rcpp/libs/Rcpp.so': /opt/lampp/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /usr/lib64/R/library/Rcpp/libs/Rcpp.so) Error: package or namespace load failed for ‘ggplot2’ Execution halted

My server using centos 6. While I got Rstudio from here (v0.99.903-x86_64)

Answer 1

My best guess -- versions of libstdc++ are getting mixed and matched; it's possible that a version of libstdc++ bundled with lampp is being used in lieu of the system libstdc++, and so R packages compiled against the system libstdc++ are now failing to load against the version bundled with lampp.

I'm not sure what the best resolution here is -- you could try rebuilding lampp against the system version of libstdc++, or rebuild your R packages against the version of libstdc++ provided by lampp?
