上述的編譯錯誤，奮鬥了兩天終於解決了，不是自己改錯的，而是上天幫助我找到Building Evolution on Windows的這一段：『
pkg-config for Win32 can be found on ftp.gnome.org, too, in http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/.
To work around a bug in MSYS bash, you need to create a file pkg-config.sh somewhere with the contents:
#!/bin/sh if pkg-config "$@" > /dev/null 2>&1 ; then res=true else res=false fi pkg-config "$@" | tr -d r && $res
And then set the environment variable PKG_CONFIG=/path/to/that/pkg-config.sh
』
也就是說，在MSYS裡，會有錯誤，所以需要新增一個pkg-config.sh的檔案，然後設定PKG_CONFIG，賓果，醬就對了，我把pkg-config.sh放在/mingw/bin下，設定PKG_CONFIG=/mingw/bin/pkg-config.sh，然後編譯這個套件就成功了，感謝神，又過一關了！
