"emilien beucler"
I have problems for running nhc98 with the -T option. I use the version 1.16, with Linux Red Hat 9, iget the following error:
The variants of the prelude/runtime libraries for the -T option are no longer provided/built by default in version 1.16, nor are the tools for browsing the traces.
Is there an other way to see the trace of a Haskell program? (I tried Hat but what i need isn't a tool like that, i really need the TRACE of the execution)
The -T option was just an earlier version of the Hat tracing system. If you use the current distribution of Hat (1.02), you will achieve exactly what -T gave you. The traces generated by Hat are indeed the full trace of execution. Perhaps it is the browsing tools which do not meet your needs? Maybe you are looking for an "animation" of how execution proceeds in a lazy language? (A student is currently working on developing such a viewer.) Regards, Malcolm
