Note that the values for bzlib
and pcre
normally contain
a date as well as the version number, and that for tre
includes
several items separated by spaces, the version number being the
second.
For iconv
this will give the implementation as well as the
version, for example "GNU libiconv 1.14"
, "glibc
2.18"
or "win_iconv"
(which has no version number).
The name of the binary/executable file for BLAS
can be used as an
indication of which implementation is in use. Typically, the R version of
BLAS will appear as libR.so
(libR.dylib
), R
or
libRblas.so
(libRblas.dylib
), depending on how R was built.
Note that libRblas.so
(libRblas.dylib
) may also be shown for
an external BLAS implementation that had been copied, hard-linked or
renamed by the system administrator. For an external BLAS, a shared
object file will be given and its path/name may indicate the
vendor/version. The detection does not work on Windows.
libcurlVersion
for the version of libCurl
.
La_version
for the version of LAPACK in use.
La_library
for binary/executable file with LAPACK in use.
