A student writes: Dr. Patt, I'm just about done with the compiler assignment, however i'm running across a weird problem. I developed my compiler code on linux01.ece.utexas.edu and it compiles beautifully and I submitted the assignment on sunfire as instructed. However, I attempted to compile it on sunfire.ece.utexas.edu and my compile failed. I noted this difference in my source code, What difference? It would have been easier to answer you if we could see the difference you talk about. I assume you used the -ansi flag when you compiled your program to run on any linux/unix platform, as we asked you to do. If you did use the -ansi flag, and the program fails to compile on sunfire but compiles on a linux platform, please let us know. however i'm afraid the grader will attempt to compile this on sunfire for grading instead of a linux box and hence give me a failing lab grade. Any suggestions? <<name withheld to protect the "afraid" student>> Yale Patt
