[BioC] LoadLibrary failures when loading RMySQL and xps packages

[Vincent Carey 525-2265]

would you please include a sessionInfo() result after triggering
the errors?

my initial guess is that there is a problem with the installation
of R 2.7

if the following is accurate

'C:/PROGRA~1/R/R-27~1.1/library/RMySQL/libs/RMySQL.dll':

the 27~1.1 seems strange to me.  send your sessionInfo and i will
attempt to replicate

> Hi,
I work with Windows XP. I recently updated to R
v.2.7 and Bioconductor v.2.2, and am now having
trouble loading libraries of packages that appear to
have been installed successfully.

An example for the workflow and error message I get
when I try to load the library for the “RMySQL”
package follows:

utils:::menuInstallPkgs()
trying URL
'http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/2.7/RMySQL_0.6-0.zip'
...
package 'RMySQL' successfully unpacked and MD5 sums
checked

The downloaded packages are in
C:\Documents and Settings\YYYYYY\Local
Settings\Temp\RtmpF3NdQe\downloaded_packages
updating HTML package descriptions

> library(RMySQL)
Error in inDL(x, as.logical(local), as.logical(now),
...) :
unable to load shared library
'C:/PROGRA~1/R/R-27~1.1/library/RMySQL/libs/RMySQL.dll':
LoadLibrary failure: The specified module could not
be found.
Error: package/namespace load failed for 'RMySQL'

I thought it was simply an issue with the RMySQL
.dll (as discussed at
http://134.148.236.121/R/e2/help/07/10/28144.html),
but I get an identical error with the xps package,
even though the xps.dll file is present in the
C:\Program Files\R\R-2.7.1\library\xps\libs folder.

Error in inDL(x, as.logical(local), as.logical(now),
...) :
unable to load shared library
'C:/PROGRA~1/R/R-27~1.1/library/xps/libs/xps.dll':
LoadLibrary failure: The specified module could not
be found.
Error: package/namespace load failed for 'xps'
This error does not appear for all downloaded
packages – for example, libraries for the
“affy”, “multtest” and “plier” packages
install fine.

Can anyone tell me why R can’t “find” the
RMySQL.dll & xps.dll files, and how to bypass this
issue? Any help would be much appreciated!

Regards,
Marie
