Win 64 package build - ERROR: loading failed for 'x64'

I did use the name Makevars.win, sorry for mistyping the name in my message as Makevar.win.

I changed the extension on the library names from *.lib to *.a in the output below precisely to avoid complaints from this list; sorry for the confusion caused by missing 2 occurrences.

The 64 bit library works fine: I can compile, link, and run a stand-alone test program that uses the 64 bit library test_win64.a. ?Since that works fine, I suspect the problem is somewhere in the process where R builds and links the 64 bit DLL. ?It may be a configuration problem, but if so, I don't understand why it does not show up in the rcmd build stage?

More precisely, I developed and tested the package under Win32 and it works. But when I move
to a 64 bit Windows 7 (Home Premium) system, and attempt to build both 32 bit and 64 bit packages,
the 32 bit package seems to build, but the 64 bit build fails.
'rcmd build test' works fine, producing DLLs in both src-i386 and src-x64

But 'rcmd check test' and 'rcmd install test' both fail.
When R attempts to load the 64 bit DLL. ?A pop-up window says
? ? R for Windows terminal front-end has stopped working,
then I get the error message on the console
? ? ERROR: loading failed for 'x64'

Below is the Makevar.win file (it selects a library based on 32 vs 64 bit).
Also below is 00install.out and R.Version() output.

I'd appreciate any suggestions.

1) Use Makevars.win, as documented, not Makevar.win. ?And your output
does not correspond to the file you showed ....

2) Use .a, not .lib (which is for MSVC).

3) I suspect your 64-bit library is broken. ?That's not an R issue, not
do we know anthing about it.
