Installing eggs in Chicken Scheme - scheme

Question

In MSYS2, I tried to intall a Chicken egg with::
chicken-install http-client
I get several errors like the following:
"c:\msys64\usr\local\bin\csc" -feature compiling-extension -setup-mode mathh.scm -shared -optimize-leaf-routines -inline -output-file mathh.so -emit-import-library mathh -emit-type-file mathh.types -local -no-procedure-checks

log2( double x )
^~~~

^~~~
mathh.c:41:1: error: static declaration of 'log1p' follows non-static declaration
log1p( double x )
^~~~~
Edit
The dependency:
chicken-install mathh
gives:
...

Edit
Fix proposed by #krl:
msys2_shell.cmd -mingw64 # see http://wiki.call-cc.org/msys2
export CHICKEN_PREFIX="c:\msys64\usr\local\\"
export CHICKEN_REPOSITORY="c:\msys64\usr\local\lib\chicken\8\\"
chicken-install -retrieve mathh
sed -i.bak -r 's/define +mathh-compile-options.+\(/&\n -C -mwin32/' ./mathh/mathh.setup
chicken-install test
chicken-install -test -transport local -location . mathh
That still gives the following errors:
...

Answer 1

It looks like this is a bug in the mathh egg. I've asked its author to take a look and he's published a new version. Can you try again?

Answer 2

from http://www.davidegrayson.com/windev/msys2/ it appears the MSYS2 -mwin32 gcc option is needed to define _WIN32. mathh uses defined(_WIN32) to trigger expansion of the q&d implementations of log2, etc. for windows.
the mathh egg mathh.setup file can be modified to supply compile-options. see the definition of mathh-compile-options in mathh.setup.
ex: (define mathh-compile-options '(-local -no-procedure-checks -mwin32))

Answer 3

I've just released http-client version 0.16 where I ripped out the overly complex md5 dependency, and replaced it with the new simple-md5 egg.
This should be much easier to install. It should appear on the egg mirrors shortly.
