An example of how to build a mostly static Tor:
Libevent should be built with:
% ./configure --disable-shared --enable-static --with-pic
An example of how to build a mostly static Tor:
./configure --enable-static-libevent \
--enable-static-openssl \
--enable-static-zlib \
--with-libevent-dir=/tmp/static-tor/libevent-1.4.14b-stable \
--with-openssl-dir=/tmp/static-tor/openssl-0.9.8r/ \
--with-zlib-dir=/tmp/static-tor/zlib-1.2.5
An example of how to build an entirely static Tor (no Mac OS X support, sorry):
./configure --enable-static-tor \
--enable-static-libevent \
--enable-static-openssl \
--enable-static-zlib \
--with-libevent-dir=/tmp/static-tor/libevent-1.4.14b-stable \
--with-openssl-dir=/tmp/static-tor/openssl-0.9.8r/ \
--with-zlib-dir=/tmp/static-tor/zlib-1.2.5
This currently does not work with --enable-gcc-hardening because of libevent issues:
configure:6176: gcc -o conftest -D_FORTIFY_SOURCE=2 -fstack-protector-all -fwrapv -fPIE -Wstack-protector
--param ssp-buffer-size=1 -I/tmp/static-tor/libevent-1.4.14b-stable -I${top_srcdir}/src/common -
L/tmp/static-tor/libevent-1.4.14b-stable -pie conftest.c -lpthread -ldl -levent -lrt >&5
/usr/bin/ld: /tmp/static-tor/libevent-1.4.14b-stable/libevent.a(event.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
/tmp/static-tor/libevent-1.4.14b-stable/libevent.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
configure:6176: $? = 1
This produces the following Tor binaries on Gnu/Linux x86-64:
% file src/or/tor
src/or/tor: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, for GNU/Linux 2.6.15, not stripped
% ldd src/or/tor
not a dynamic executable
o Minor enhancement
- Implements --enable-static-tor for configure time. Closes bug 2702.
Idea, general hackery and thoughts from Alexei Czeskis, John Gilmore,
Jacob Appelbaum.
