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
