It seems that the subversion windows build does not support apr 1.6.3, apr-utils 1.6.1 and apr-icon 1.2.1-R2 with unbundled libexpat.
Did I miss something or is the state of play at the moment? Calling gen-make.py like this for svn 1.9.7: py -2 gen-make.py -t vcproj --vsnet-version=2015 --release ^ --with-apr=%TARGET%\apr ^ --with-apr-util=%TARGET%\apr-util ^ --with-apr-iconv=%TARGET%\apr-iconv ^ --with-serf=%TARGET%\serf-%SERF_VER% ^ --with-openssl=%TARGET%\openssl ^ --with-zlib=%TARGET%\zlib-%ZLIB_VER% ^ --with-sqlite=%TARGET%\subversion-%SVN_VER%\sqlite-amalgamation ^ --disable-gmock I see the following error: ERROR: 'C:\BuildRoot\Win64-VC-14.0-1.9.7\apr-util\include\expat.h' not found. Use '--with-apr-util' option to configure APR-Util's XML location. Barry
