Calling functions in `make-flags'

[Sree Harsha Totakura <sreeharsha@totakura.in>]

Hi,

I am trying to build a package which does not have 'configure' script.
It instead relies solely on a makefile.  For this to function, I have to
set the 'SH' variable inside the Makefile to a valid shell.

I am trying to set the 'SH' variable through build-flags like this:
> (arguments
>     '(#:make-flags '((string-append "SH=" (which "sh")))

But this fails with the following error:

> 203: 1 [build #:make-flags ((string-append "SH=" (which "sh"))) ...]
> In unknown file:
>    ?: 0 [system* "make" "-j" "4" (string-append "SH=" (which "sh"))]
> 
> ERROR: In procedure system*:
> ERROR: Wrong type (expecting string): (string-append "SH=" (which "sh"))

How can I get this to work?

Regards,
