Hello,
I am working on a WIN64 platform and trying to install from source a
package "myPackage" that links to dll compiled in 64 bits.
Under R prompt I launch
install.packages("/Path/To/myPackage.tar", , repos = NULL,
type="source")
and I read that it is the 32 versions of g++ that is used
g++ *-m32* -shared -s -static-libgcc -o myPackage.dll tmp.def
toto01.o toto02.o RcppExports.o toto03.o
-LC:/Path/To/MyWIN64Libraries -laWIN64Lib
-Ld:/RCompile/CRANpkg/extralibs64/local/lib/i386
-Ld:/RCompile/CRANpkg/extralibs64/local/lib
*-LC:/PROGRA~1/R/R-31~1.0/bin/i386* -lR
There are several things I do not understand in this trace:
a) the -m32
b) why it is 32bits version of R that is used when my path contains
the 64 version (PATH = ...;C:\Program Files\R\R-3.1.0\bin\x64;...)
When I compile through DOS and enter
R CMD INSTALL --no-multiarch myPackage
I observe that it is the correct (64 bits) version that is used but I
would rather install my package through the usual install.packages
command. Is there a way to do this ?
Best regards, Jérôme
