Dear list users,
The problem occurs when library(RPostgreSQL) is issued on R. This issue
has previously appeared on R mailing list without any robust solution.
The error message issued by R:
Loading required package: RPostgreSQL
Loading required package: DBI
Error in inDL(x, as.logical(local), as.logical(now), ...) :
unable to load shared library
'C:/PROGRA~1/R/R-210~1.1/library/RPostgreSQL/libs/RPostgreSQL.dll':
LoadLibrary failure: Unable to locate the specified module.
Error: package 'RPostgreSQL' could not be loaded
At the same time an error box appears saying that a given DLL does not
exists which makes RPostgreSQL loading to fail. The message appears for
any of the following DLLs (that actually exist on
X:/PostgreSQL_installation_directory/bin):
libpq.dll
ssleay32.dll
libeay32.dll
libintl-8.dll
libiconv-2.dll
krb5_32.dll
comerr32.dll
k5sprt32.dll
msvcr71.dll
gssapi32.dll
To "solve" this problem the actual DLLs from the PostgreSQL installation
directory must be copied into the X:/WINDOWS/System32 shared libraries
folder in order to make the package operational.
Is there a way to solve this from the package internals without having
to copy the DLLs? Am I missing something here?
I'm using R-2.11.1 on WinXP/7.
Best regards,
João Gonçalves.
