When I configure (under cygwin environment), an error occurred, Message are following:
$ ./configure
.................
checking build system type... /bin/sh: ./config.guess: No such file or directory
configure: error: cannot guess build type; you must specify one
How to resolve it? Thanks!!
search for /usr/share/automake*/config.guess
check the latest version of automake
$ which automake
$ automake --version
find the appropriate automake folder in /usr/share/automake.1.11.1/config.guess
replace config.guess from your build tree with /usr/share/automake.1.11.1/config.guess
(The same may/is usually needed for config.sub.)
The error message may also include instructions on how to deal with this. In my case I saw
This script, last modified 2008-01-23, has failed to recognize
the operating system you are using. It is advised that you
download the most up to date version of the config scripts from
http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD
and
http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD
In a browser I was able to access those files, save them to to my system, and then overwrite the respective ./config/config.guess and ./config/config.sub files in the package being built.
config.guess and config.sub routines are updated and kept on github;
You'll get the web pointers when you run the script,
./config.guess
In my Mingw system, config.sub or .guess were not in the share/../automake-1.11/ tree, I needed to download the updated scripts which worked (when they replaced the old ones).
for AUR based builds add the following command to the PKGBUILD (end of prepare section) to have proper config.guess automatically applied/overrided in the package:
cp /usr/share/automake-`pacman -Q --info automake|grep -i version| awk -F ":" '{print $2}'| awk '{$1=$1};1'| awk -F "." '{print $1"."$2}'`/config.guess .
