已安装ROracle，但安装相关软件包时加载失败

Question

I'm working on a Windows Server x64 with R version 3.5.1 (see sessionInfo for details ).

ROracle package version 1.3-1 is already installed (see installed.packages details ) and works fine (see ROracle call example ).

I intend to install an internal developed R package which has the following dependencies declared in its 'DESCRIPTION' file : " Depends: R (>= 3.1.0), DBI, ROracle ".

When I launch this internal package installation, I get the following error message (see attached screenshot for full error message ):

** testing if installed package can be loaded

*** arch - i386

Error : package 'ROracle' is not installed for 'arch = i386'

Error: loading failed Execution halted

*** arch - x64

ERROR: loading failed for 'i386'

For information this package has already been installed on several computers without facing any error, the first trouble happens on this virtual machine.

Answer 1

It looks like the installation you are running for your package is testing your package in a multiarch environment, which is therefore checking the dependencies in a multiarch environment. There would be 2 ways around this:

1. Install a 32-bit ROracle client in addition to the 64-bit, set the appropriate OCI_LIB32 environment variable, and re-install ROracle so it is aware of both architectures.
2. Add the --no-multiarch option to your install, so either R CMD INSTALL --no-multiarch or install.packages(...,configure.args = c("--no-multiarch")) .
