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.
And he seems to have missed
R CMD check --help
includes
--install-args= command-line args to be passed to INSTALL
so I would have used
R CMD check --install-args=--force-biarch
(and when I do, it works for me).
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?]
No, it's not configure's job to detect anything but the current architecture.
Typically it needs to modify files so it can only modify them for one
architecture. Your use of configure is very odd since you don't actually
configure the package, you are copying dependencies into installation
directories (so you can't even test it without override - that's very unusual
and a bit questionable).
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.
You probably mean to use R --arch i386 to check your 32-bit version -
architectures are normally tested separately.
Cheers,
Simon
