Using MinGW64 version 4.7.3-- thread model win32-- running naively (no
cross-compile) inside msys2, I tried to build the tor-0.2.8.9 source
downloaded from torproject.org.
While configuring the build, I noticed I had to build and install
libevent, openssl, and zlib, which I did. After that Configure didn't fail
anymore, and I proceeded to build tor by issuing "make". It seemed to go
pretty well until the linker wanted to build tor.exe. It failed and
complained about undefined references. Here is the output after issuing
the make command again.
$ make
make all-am

I have googled around and have not found an answer to solve this problem.
