Lame me, I found the answer here:
http://haskell.org/ghc/docs/6.10.2/html/users_guide/template-haskell.html
ghc -fforce-recomp --make -cpp -O -DXQUERY2_TEST Main
ghc -osuf p_o -prof -auto -auto-all -fforce-recomp --make -cpp -O
-DXQUERY2_TEST Main

Hi
I'm trying to build some modules that use TH with profiling enabled.
The normal build works:
$ ghc -fforce-recomp --make -cpp -O -DXQUERY2_TEST Main [1 of 8] Compiling Text.XML.Expat.FormatCustom ( Text/XML/Expat/FormatCustom.hs, Text/XML/Expat/FormatCustom.o ) [2 of 8] Compiling DataStructures ( DataStructures.hs, DataStructures.o ) Loading package ghc-prim ... linking ... done. Loading package integer ... linking ... done. Loading package base ... linking ... done. Loading package syb ... linking ... done. Loading package array-0.2.0.0 ... linking ... done. Loading package packedstring-0.1.0.1 ... linking ... done. Loading package containers-0.2.0.1 ... linking ... done. Loading package pretty-1.0.1.0 ... linking ... done. Loading package template-haskell ... linking ... done. Loading package mtl-1.1.0.2 ... linking ... done. Loading package filepath-1.1.0.2 ... linking ... done. Loading package old-locale-1.0.0.1 ... linking ... done. Loading package old-time-1.0.0.2 ... linking ... done. Loading package unix-2.3.2.0 ... linking ... done. Loading package directory-1.0.0.3 ... linking ... done. Loading package process-1.0.1.1 ... linking ... done. Loading package random-1.0.0.1 ... linking ... done. Loading package derive-0.1.4 ... linking ... done. [3 of 8] Compiling Utils ( Utils.hs, Utils.o ) [4 of 8] Compiling Semantics.Pure ( Semantics/Pure.hs, Semantics/Pure.o ) [5 of 8] Compiling Database ( Database.hs, Database.o ) [6 of 8] Compiling XPathDSL ( XPathDSL.hs, XPathDSL.o ) [7 of 8] Compiling QueryParse ( QueryParse.hs, QueryParse.o ) [8 of 8] Compiling Main ( Main.hs, Main.o ) Linking Main ...
But profiling one fails:
$ ghc -prof -auto -auto-all -fforce-recomp --make -cpp -O -DXQUERY2_TEST Main [1 of 8] Compiling Text.XML.Expat.FormatCustom ( Text/XML/Expat/FormatCustom.hs, Text/XML/Expat/FormatCustom.o ) [2 of 8] Compiling DataStructures ( DataStructures.hs, DataStructures.o ) Loading package ghc-prim ... linking ... done. Loading package integer ... linking ... done. Loading package base ... linking ... done. DataStructures.hs:1:0: Dynamic linking required, but this is a non-standard build (eg. prof). You need to build the program twice: once the normal way, and then in the desired way using -osuf to set the object file suffix.
The error message is somewhat cryptic to me. Does anyone know how to perform profiling build when using TH?
