Hi all, I have an application that uses a package called 'uust'. Normally I would compile using;

ghc -O2 -o genAST -fglasgow-exts -package uust GenAst.hs

This works fine. However, I want to profile my application and therefore need to add -prof. The uust package was compiled for profiling (there are _p files), but when I compile using;

ghc -prof -O2 -o genAST -fglasgow-exts -package uust GenAst.hs

I get undefined references during the link phase;

GenAST.o(.rodata+0xe5f0): undefined reference to `UUziParsingziInterface_lvl8_closure' GenAST.o(.rodata+0xe630): undefined reference to `UUziParsingziInterface_zdwevalStepsIOzq_closure' GenAST.o(.rodata+0xe6cc): undefined reference to `UUziPrettyziBasic_lvl19_closure' GenAST.o(.rodata+0xe6e8): undefined reference to `UUziParsingziInterface_lvl8_closure' GenAST.o(.rodata+0xe724): undefined reference to `UUziParsingziInterface_zdwevalStepsIOzq_closure'

and many many more. I'm kinda in the dark here what I'm doing wrong. Can anyone help?

It looks like there's something wrong with the profiling version of your uust package: either some of the object code is missing, or it doesn't correspond to the .p_hi files. I would check your uust package build. Cheers, Simon
