Help, My Rgui.exe, main.f, main.o, and main.dll are all in the same directory. When I try to set a breakpoint, I get this response
(gdb) b main.f:3 No source file named main.f I tried the -gdwarf-2 requirement in both the compiling and linking statements. This did not fix the problem. The cygwin site recommended the -g option. I tried this. This did not fix the problem. I did not use R CMD SHLIB ( I ran the statements manually ).
