Re: Building headless Bitcoin and Bitcoin-qt on Windows

Given that, I used a solution from StackExchange:

Code:

ACLOCAL_PATH=/usr/share/aclocal ./autogen.sh

in the bitcoin directory and that avoided the PKG_... errors during the execution of ./configure.

You are actually setting ACLOCAL_PATH to the default search path.

Code:

$ aclocal --print-ac-dir
/usr/share/aclocal

ACLOCAL_PATH is ignored by msys-autoconf (afaik), this is why pkg.m4 needs to be installed to /usr/share/aclocal (--prefix=/usr when configuring).
