Well, having made the same installation of Rtools for rw1031 in a Win98 box (the former one was my Win95 labtop) to get advantage of significantly more RAM, I try C:\alobo\Rseg>Rcmd SHLIB test.c make: /bin/sh.exe: Command not found make: *** [libR] Error 127 despite the fact that I made a C:\bin directory and copied sh.exe there. Actually, if I just type sh in the MS-DOS window, it works (I've put the C:\bin directory in the path). I've also tried runing from within C:/bin C:\bin>Rcmd SHLIB C:\alobo\Rseg\test.c make: /bin/sh.exe: Command not found make: *** [libR] Error 127 Could be a problem with / and \ ? Does Win98 behaves differently than Win95 on that regard?
