問題:

checking for SHELL_CORE... configure: error: Package requirements (libxml-2.0 >= 2.5.0 gtk+-2.0 >= 2.21.5 gio-2.0 >= 2.25.11 gthread-2.0 ) were not met:

No package 'libxml-2.0' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables SHELL_CORE_CFLAGS
and SHELL_CORE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

対策:

export PKG_CONFIG_PATH=/mingw/lib/pkgconfig/
