It seems not so easy and I am not sure that my solution always works,
but at least it worked for the examples that I tried.
In order to tell ghc to link everything statically, it seems necessary
to pass the options "-static -optl-static -optl-pthread" to ghc.
Note that the KiCS2 option ":set rts -optl-static" that you tried
are only run-time options but not compilation options.
ghc compilation options can be set in KiCS2 by the command
":set ghc ...", i.e., for static linking you need to set
> :set ghc -static -optl-static -optl-pthread
in KiCS2. Then static linking should be performed when you create
an executable by the command ":save" (although the linker produces many
warnings). However, the setting of ghc options is only possible
in "local" installations of KiCS2. In "global" KiCS2 installations
(which are the default ones since they ensure faster compilation),
this option is disabled since all libraries are precompiled and there
might be conflicts when precompiled libraries are linked to programs
compiled with different ghc options. Thus, in order to set these
options, you have to install KiCS2 "locally". This can be easily done
by setting the variable
GLOBALINSTALL=no
in the main Makefile of KiCS2 before installing it. I hope this works.
Alternatively, we could also offer the setting of ghc options
in the standard global installation "at your own risk", if this is
desirable. Please let me know if this is a desired feature.
Best regards,
Michael
