Syswtem configuration: OS Win8.1 x64 MSYS2 + MinGW version 6.2.0 (Rev2, Built by MSYS2 project) libevent 2.1.7 rc OpenSSL 1.1.0c Tor 0.3.0.1 alpha This is how I try to build Tor (which is working with OpenSSL 1.0.2j just fine): cd /d/tor-mingw tar xvzf tor-0.3.0.1-alpha.tar.gz cd tor-0.3.0.1-alpha ./configure --prefix=$PWD/dist --with-libevent-dir=/d/tor-mingw/libevent-release-2.1.7-rc/dist --with-openssl-dir=/d/libs/openssl-1.0.2j --disable-asciidoc --enable-local-appdata I then get the following OpenSSL related error from configure: checking for openssl directory... /d/libs/openssl-1.1.0c checking whether we need extra options to link openssl... configure: error: Found linkable openssl in /d/libs/openssl-1.1.0c, but it does not seem to run, even with -R. Maybe specify another using --with-openssl-dir} Trying with CPPFLAGS="-I/d/libs/openssl-1.1.0c/dist/include" LDFLAGS="-L/d/libs/openssl-1.1.0c/dist/lib" in configure also leads to the same error :-/. This is how I build OpenSSL: cd /d/libs tar xvzf openssl-1.1.0c.tar.gz cd openssl-1.1.0c ./Configure --openssldir=$PWD/dist --prefix=$PWD/dist shared mingw64 no-ssl3 enable-ec_nistp_64_gcc_128 make depend && make && make install This is how I build libevent: cd /d/tor-mingw tar xvzf libevent-release-2.1.7-rc.tar.gz cd libevent-release-2.1.7-rc ./autogen.sh ./configure --prefix=$PWD/dist --enable-static --disable-shared CPPFLAGS="-I/d/libs/openssl-1.1.0c/dist/include" LDFLAGS="-L/d/libs/openssl-1.1.0c/dist/lib" make && make install Any ideas for me?
