I'm having problems getting R CMD check to work correctly on Windows 7 (64 bit)
in a package that uses C code. What I want to do is to be able to pass the
equivalent of the "--force-biarch" option to check, but this is only supported
for INSTALL.
Background:
I'm writing a package (RNetica) which forms a link between R and a third-party
library (Netica.dll). The vendor supplies this library in both a 32 bit and a
64 bit version.
Under Linux, I use configure to link against the 32 or 64 bit version of
libnetica.a as appropriate.
Under Windows, I use configure.win to copy the 32 and 64 bit versions to
"$R_PACKAGE_DIR/libs/i386" and "$R_PACKAGE_DIR/libs/x64" respectively.
Installation:
This mostly works. If I run R CMD INSTALL RNetica, R detects the configure.win
and only builds the 64 bit version of RNetica. [I'm not entirely clear on why
R doesn't at least try to build both architectures. Wouldn't the default
assumption be that the author wrote the configure.win file to handle both
cases?] But if I use R CMD INSTALL RNetica --force-biarch, it correctly builds
and installs both the 32 and 64 bit versions. I can verify that I can load my
library and call a few functions that exercise the DLL.
Checking:
When I run R CMD check RNetica, I get the following problem in my 00install.out
log:
> Warning: this package has a non-empty 'configure.win' file,
> so building only the main architecture
It then fails with the message:
> Error: .onLoad failed in loadNamespace() for 'RNetica', details:
> Call: library.dynam("RNetica",pkgname, libname)
> Error: DLL 'RNetica' not found: maybe not installed for this architecture?
Sure enough, if I check the directory RNetica.Rcheck/RNetica/libs/x64
It has Netica.dll, RNetica.dll, and symbols.rds
If I check the directory RNetica.Rcheck/RNetica/libs/i386
It only has Netica.dll (copied there by the configure.win).
If I run R CMD check RNetica --no-multiarch, this test runs correctly.
If I run R CMD check RNetica --extra-arch, this fails at the same point.
Thanks in advance for any help.
