Many thanks to Professor Ripley for responding to my earlier post, included below, about trying to use mingw32 gcc.I did put back the original Rinternals.h. I am still crashing R every time I try to use C code.
Here is what I did, basd on readme.packages:
1.) Ensured that C:\Rtools was first in my path, and obtained a new tools.zip from BDR's R tools site.
2.) Ensured that I do have Mingw-1.1, whose bin directory is in my path. Here is my path:
3.) Installed ActivePerl 5.6.1.
4.) Set R_HOME to C:\Rw1051
5.) edited MkRules: set only HEADER=C:\mingw-1.1\include
6.) Tried to make make libR.a:
dlltool -k --as as --dllname R.dll --def R.exp --output-lib libR.a
make: dlltool: Command not found
make: *** [libR.a] Error 127
Now, dlltool.exe is in mingw-1.1\bin, which is in my path. I
have no idea why that file is not found!
I tried a google search and found some earlier reports of
Error 127 and dlltool problems with R, but most seem to
involve using rcmd INSTALL.
What is my next step here? Have i missed something obvious in readme.packages? Thanks in advance...
