common lisp - I'm getting an error message I get when attempting to Install CL-PNG in Emacs using Quicklisp -


i hope answers can others in installing lisp packages in general. installed libpng setup.exe (at link: http://sourceforge.net/projects/gnuwin32/files/libpng/1.2.37/libpng-1.2.37-setup.exe/download?use_mirror=iweb)...i didn't manually....i'm using sbcl lisp implemaenation. tried run (ql:quickload "png")in emacs keep getting error message when do:

external process exited code 1. command was: "c:/mingw/bin/gcc.exe" "-m32" "-i/opt/local/include" "-i/program files (x86)/steel bank common lisp/1.1.4/site/cffi/" "-o" "d:\users\w\appdata\local\common-lisp\cache\sbcl-1.1.4-win-x86\d\users\w\appdata\roaming\quicklisp\dists\quicklisp\software\cl-png-0.6\grovel.exe" "d:\users\w\appdata\local\common-lisp\cache\sbcl-1.1.4-win-x86\d\users\w\appdata\roaming\quicklisp\dists\quicklisp\software\cl-png-0.6\grovel.c" output was:

[condition of type simple-error]

other things tried:

i took dll files d:\program files (x86)\gnuwin32 (folder libpng installed), dll files pertaining libpng is, , copied them sbcl\1.14 folder common practice dll files sbcl can access them. still got above error:

i'm in windows 8 - added d:\program files (x86)\gnuwin32\ (folder libpng installed) path enviornment variable because libpng setup.exe didn't seem add enviornment variable , no luck still same\above error in emacs ....any appreciated

you found solution within past 5 months, this blog shows answer , nice reference future readers, think.

citing (and shortening) original author:

you have copy files ffi.h , ffitarget.h , gsl folder include folder of libffi installation , paste them include folder of mingw installation.
