f951.exe: sorry, unimplemented: 64-bit mode not compiled
The original post below refers to an issue that arose with glmnet. It has since been fixed but the underlying problem (I believe) is a bug in gcc/gfortran 2.6.3 toolchain. Here is a reproducible example, test.f90. program dblbug real :: x, y x=2 y=exp(dble(x)) end program dblbug Compile with gfortran -fdefault-real-8 -o test test.f90. The program will crash on Windows but not on i386 or x86_64 linux (same version of toolchain) but I think that says nothing. Note: The glmnet code was originally written for single precision and hence the flag -fdefault-real-8. The fix was to just to remove the "dble." -Naras

Hello:
Under my Windows 7 system, "R CMD check DiercxkSpline_1.1-5.tar.gz" fails because:

This typically means that you're using the wrong (old) compiler. The new MinGW compilers support both -m32 and -m64. You have to set the PATH to the new compilers (in the gcc-4.6.3 subdirectory of Rtools) *before* any old compilers in Rtools. Cheers, Simon

A similar problem was reported for package "glmnet" (http://stackoverflow.com/questions/10291189/compiling-glmnet-failed-in-windows) plus one with R 2.14.2 (http://r.789695.n4.nabble.com/Problems-when-building-a-package-for-Windows-64-td4464488.html). However, I get this with R 2.15.0 and the latest R tools (reinstalled earlier today). On R-Forge, DierckxSpline has "Build status: Current", which suggests that R-Forge does NOT have this problem. I read through the two replies to these two earlier questions without seeing how to fix my problem.
Thanks in advance for any suggestions.
