I'm puzzled because (since someone complained about the packages), I did retest Windows 10 and Windows 8 with each of the installers. > installers required the C++ 2012 (and/or C++2013) redistributables.

I did - I built using 2012, 2015, 2017, both 32-bit/64-bit, and provide installers for the 2012 with 32-bits. > 2. *Using configure on msys2* msys2 won't give you a _native_ Windows executable. Think of it as a cut-down Cygwin. I do cross-compiles for mingw (32/64), but the state of packages for supporting libraries has never been worth much (commenting on both Debian and Redhat). > * Alternatively, I also tried using msys2 and configure a makefile. > The configure command look like this: yes... but there's always the issue of compiling for the current environment (which msys2 can do) and targeting something like native Windows. Cross-compiling from Debian or Fedora is simpler, but I've gotten the most useful builds from Visual Studio :-) > ./configure --with-curses-dir=/c/no_space/lynx-cur/PDCurses-3.9/ > --with-screen=pdcurses > > But here it fails with this error: > > configure: error: Unable to successfully link Athena library > (-lXaw) with test program sure - the PDCurses X11 libraries are what it's looking for.

I am not sure, why I am failing at all methods. I attempted to send an attachment with scripts, but don't see either try. On my machines, I have a shortcut to a script which sets environment variables, which then starts winvile. From winvile, I run "all-lynx.bat", which builds a half-dozen configurations of lynx. Using winvile that way, I collect the logs for each compiler configuration: -rw-r--r-- 1 tom users 620283 Feb 27 20:23 /usr/build/lynx/logs/vs2008x32.log -rw-r--r-- 1 tom users 620356 Feb 27 20:29 /usr/build/lynx/logs/vs2010x32.log -rw-r--r-- 1 tom users 620324 Feb 27 20:34 /usr/build/lynx/logs/vs2012x32.log -rw-r--r-- 1 tom users 624050 Feb 27 20:44 /usr/build/lynx/logs/vs2012x64.log -rw-r--r-- 1 tom users 617665 Feb 27 20:49 /usr/build/lynx/logs/vs2015x32.log -rw-r--r-- 1 tom users 621248 Feb 27 20:53 /usr/build/lynx/logs/vs2015x64.log -rw-r--r-- 1 tom users 617677 Feb 27 20:59 /usr/build/lynx/logs/vs2017x32.log -rw-r--r-- 1 tom users 621499 Feb 27 21:04 /usr/build/lynx/logs/vs2017x64.log (I had a VS 2013 on my preferred machine, but an upgrade broke it). -- Thomas E.
