[R] Debugging makefiles.

[rkevinburton at charter.net]

Thank you.

I found the problem. For some reason there was a zero-length file with the name of 'r' in the bin directory. When I removed this the build worked fine. I still don't know why this file caused a problem but I am happy with the solution.

I recopied the source (overwritting the existing files) followed by a 'make clean' and 'make all recommended' and received the same error. I am really lost. It must be something in my environment but I don't know how to track it down.

I have not changed any of the Makefiles so I am not sure where this error is coming from or how best to trace the root of the problem. Maybe someone with a little more knowledge on the 'R' source structure and build process could help me out with a little advice here. If have tried the '-d' option but that is entirely too much debug information for me to digest. I just need to know where '../../bin/R' is needed and why it is not found.
