By the way without --ghc-option="-optl -static" everything works and it produces a nice dynamic binary. Regards Nicola On Tue, 2008-08-12 at 13:21 -0700, Don Stewart wrote:

It seems that the -static flag serves a different purpose: according to the GHC manual it forces the compiler use the static Haskell libraries, but the resulting binary is still dynamically linked to the C libraries. What is the correct flag to create a static binary? Thanks

Pass -optl-static to GHC.

No space between "-optl" and "-static". The "-pthread" is probably being misrecognized as a result of the generated command.

It works! This is much easier, thank you Nicola On Thu, Aug 14, 2008 at 11:30 PM, Agent Zhang wrote:

Well, it needn't be that hacky ;) The following command works for me and it does essentially the same thing:

ghc -i -static -optl-static -optl-pthread -funbox-strict-fields -fwarn-incomplete-patterns -isrc --make Main -o bin/restyscript

Please note that without -optl-pthread option, I'll get exactly the same errors:

-lpthread needs to be put to the end of the argument list to help gcc or ld solve the symbols properly.

Hope this helps ;)

Nicola: I had the same problem using the GHC 6.8.2 Debian package. Igloo promises me that GHC 6.8.3 fixes this problem, but I haven't seen that in the Debian repository yet.

GHC 6.8.3 does not have this problem at least on my machine ;) Regards, -agentzh
