Hi-
I am also having trouble installing RMySQL (OS X 10.4.7, R2.3.1,
MySQL 5.0.24, RMySQL 0.5-7, all 32 bit PPC). DBI loads fine, but when
I try to load RMySQL I get the following:
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library '/Library/Frameworks/R.framework/
Versions/2.3/Resources/library/RMySQL/libs/ppc/RMySQL.so':
dlopen(/Library/Frameworks/R.framework/Versions/2.3/Resources/
library/RMySQL/libs/ppc/RMySQL.so, 6): Symbol not found: _load_defaults
Referenced from: /Library/Frameworks/R.framework/Versions/2.3/
Resources/library/RMySQL/libs/ppc/RMySQL.so
Expected in: flat namespace
Error in library(RMySQL) : .First.lib failed for 'RMySQL'
I downloaded the source for RMySQL, compiled it (gcc 4.0.0), and got
the exact same result. I also tried with MySQL 5.0.20 and MySQL
4.0.21, and again got the same result.
Was anyone else able to resolve this problem? Are others able to get
RMySQL running on similar machines without encountering this problem?
A couple possibilities come to mind:
-Something is broken about my system that prevents the linking of all
the necessary system libraries (eg different versions of gcc were used).
-Something wrong with my mysql installation that is making the
libraries inaccessible.
-The "TODO" comments in RS-MySQL.c regarding OS X mean that the
RMySQL implementation on OS X is not complete.
If this is a system libraries issue, I wonder if it's related to the
libmysqlclient.a problems that were encountered late last year (see
"RMySQL problem" thread from November 18 2005).
Thanks,
Casey
