Unfortunately, -debug seems to conflict with -threaded: ghc --make -threaded -debug -O -Wall [...] -o postmaster tutorial.lhs [...] Chasing modules from: tutorial.lhs [...] Compiling Main ( tutorial.lhs, .objs/Main.o ) Linking ... /usr/lib/gcc-lib/i686-pc-linux-gnu/bin/ld: cannot find -lHSrts_thr_debug collect2: ld returned 1 exit status Would compiling with -debug and without -threaded still help?
