We've added a column at

http://cran.r-project.org/web/checks/check_summary.html

of test results using the Sun Studio compiler: it is intended that these will be updated weekly.

The Sun Studio compiler is that used on Solaris: these runs were on the Linux version. All the other platforms are using gcc 4, so this provides an opportunity for checking for use of gcc-specific features and also standards conformance (the Sun compilers have a long-time reputation for close conformance to the language standards).

There are known problems where packages use C++ or JNI interfaces (e.g. rgdal and EBImage) as the libraries and JVM were compiled under gcc's conventions (even though a Sun JVMi is used). About half the packages using rJava segfault, which seems to a JNI issue.

Some packages use gcc-specific compiler flags:

   LogConcDEAD Matching amap geometry memisc taskPR

but the vast majority of the errors reported are C++ errors. One class that may not be immediately obvious is the use of C headers in C++: you are supposed to write e.g.

#includd <cmath>

NOT
#include <math.h>

Symptoms of this can be seen for packages
