    <p>We are a team working on an R package containing C/C++ code. The package can successfully be installed on all the machines but one. These all run the same version of Mac OS X. I have provided the log files for the installation of the package on my computer (success) and a colleague's computer (error). The package depends on the Rcpp package and the GSL library, both of which were successfully installed on both machines.</p> <p><strong>My Computer</strong></p> <pre><code>WARNING: ignoring environment value of R_HOME * installing to library '/Users/dejayn/R/x86_64-apple-darwin10.8.0-library/2.15' * installing *source* package 'mrenci' ... ** libs *** arch -

This issue, however, appears to have been mitigated by forcing the targeting of a single architecture <code>x86_64</code>. It is also worth noting that as a result of these errors, all computers now have several versions of R and g++. Is this an issue with the linker? Does the same compiler need to be used for both R and its packages? In the case of my computer, I never explicitly asked for <code>g++-mp-4.5</code> to be used rather than the default g++ (version 4.2), so I figured R automatically detects it.</p> <p>In case this is of any help, here is what my Makevars contains:</p> <pre><code>PKG_LIBS=`$(R_HOME)/bin/Rscript -e "Rcpp:::LdFlags()"` $(SHLIB_OPENMP_CFLAGS) -fopenmp PKG_CPPFLAGS=$(SHLIB_OPENMP_CXXFLAGS) -fopenmp PKG_CFLAGS=$(SHLIB_OPENMP_CFLAGS) -fopenmp </code></pre> <p>The <code>$(SHLIB_OPENMP_*FLAGS)</code> flags seem to be defined only on my computer; <code>-fopenmp</code> flags were explicitly added for the package to work on all the machines.</p> <p>Has anyone experienced similar issues? Any help would be appreciated.</p>
