Installing eggs in Chicken Scheme

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:

...
mathh.c: In function 'stub181':
mathh.c:357:19: warning: implicit declaration of function 'mm_hypot'; did you mean '_hypot'? [-Wimplicit-function-declaration]

                   ^~~~~~~~
                   _hypot

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:

...

installing mathh: ...

   extern double __cdecl log2 (double);
                         ^~~~
... further errors like above

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.

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))

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?
