Hi, I replaced my Rtools today as posted at http://www.murdoch-sutherland.com/Rtools/Rtools.exe Trying to build R-devel_2007-12-13.tar.gz without modifying MkRules gives the gfortran command not found error below. I am wondering if gfortran.exe is missing from (recent?) Rtools.exe or I am doing something wrong. Thanks to hints at Duncan's site, I worked around the error by adding "GCC4_SUFF=-sjlj" in MkRules (below the == end of user-customizable parts == line). gcc -std=gnu99 -I../include -DHAVE_CONFIG_H -DR_DLL_BUILD -O3 -Wall -pedantic -c zeroin.c -o zeroin.o gfortran -O3 -c ch2inv.f -o ch2inv.o make[4]: gfortran: Command not found make[4]: *** [ch2inv.o] Error 127 make[3]: *** [rlibs] Error 2 make[2]: *** [../../bin/R.dll] Error 2 make[1]: *** [rbuild] Error 2 make: *** [all] Error 2
