In a project I needed to have statically built tor.exe (single executable) for windows. Official tor expert bundle distribution has many dll files which is undesirable for my needs. So I compiled it under windows using mingw and msys for x86 architecture. Since it is a tedious job to compile all tor dependencies and tor, I put it here for good. Zip file includes only tor.exe, tor-gencert.exe and tor-resolve.exe as well. If you don't need tor-gencert.exe and tor-resolve.exe, you can delete them.

Building TOR having a static executable is described below. If you are familiar with Linux shells, it is easier for you. Follow the instructions below. If you have any problem, do not hesitate to ask. I put lots of environment variables and compiler/linker flags to be on the safe side even if they are useless. Let me know if anything is unnecessary. If you do not need a static executable, just visit tor website and download tor expert bundle.

# The configuration parameter "--disable-gcc-hardening" builds Tor without requiring
# the libssp-0.dll. If you build without this parameter then don't forget to copy
# libssp-0.dll from /mingw32/bin to the folder where tor.exe is located. libssp is
# a library for stack protection.
