can't build static binary of simple_client or client_test #142

Open GoogleCodeExporter opened 9 years ago

What steps will reproduce the problem?
1. Follow steps to build libtorrent from here:
http://www.rasterbar.com/products/libtorrent/building.html
(I've actually tried it with the latest SVN and the latest release from here as 
well:
https://code.google.com/p/libtorrent/downloads/detail?name=libtorrent-rasterbar-
0.15.4.tar.gz&can=2&q=)  I have also tried it using autotools and BBv2, and 
with boost from the repos and built from source.
2. Try to compile a static binary for anything linking to libtorrent.

What is the expected output? What do you see instead?
A static binary.  Instead I see a variety of error messages, I believe the 
closest I have came so far was using 0.15.4, with boost from source, using bbv2:

What version of the product are you using? On what operating system?
I've tried latest SVN (revision 5110 I believe), and also 0.15.4.  My OS is 
Ubuntu 10.04 Lucid x86_64.  gcc is version 4.4.3 (Ubuntu 4.4.3-4ubuntu5), boost 
is 1.40.0 (tried pre-compiled from repos, and from source)

Please provide any additional information below.
The 'official' commands I have used to build this from the manual include:
'bjam gcc link=static runtime-link=static boost=source'
and
'./configure --enable-static --enable-shared --disable-geoip --disable-debug 
--enable-tests --enable-examples CXXFlags="-UTORRENT_USE_I2P 
-DTORRENT_DISABLE_RESOLVE_COUNTRIES -UANSI_TERMINAL_COLORS"'
which gets me both libtorrent-rasterbar .so and .a, and I try to compile 
client_test like so:
'g++ -I./include/ -ltorrent-rasterbar -L./src/.libs/ -o client_test.amd64 
./examples/client_test.cpp -UTORRENT_USE_I2P 
-DTORRENT_DISABLE_RESOLVE_COUNTRIES -UANSI_TERMINAL_COLORS 
-DTORRENT_DISABLE_GEO_IP -static'
Without the '-static' on the end, it works perfectly, but with it it fails.

So I don't know where the problem is, but I'm hoping it's a silly little flag 
I'm missing someplace.

I've done some more investigating, and if I force bjam to use my own 'custom' 
g++ that looks like this:

#!/bin/sh
/usr/bin/g++ -fPIE -pie -static -static-libgcc -m32 "$@"

(notice I am compiling a 32-bit executable now, same 64-bit host though)

Then it will actually spit out a client_test executable, unfortunately it is 
still not static.  This is the tail end of the building log that possibly 
explains why and then a run of 'file' which shows it is dynamically linked:

So is there a way to get a statically compiled binary of libtorrent and/or 
client_test?

when you say "statically linked", you're not talking about linking statically 
against boost or libtorrent, you're talking about the runtime library, right?

I would expect this to work: (in libtorrent/examples):

   bjam boost=source link=static runtime-link=static boost-link=static encryption=openssl

to work. However, testing this it turns out that it will try to link statically 
against libdl.so, which doesn't have a corresponding static library. libdl is 
required by libcrypto. One simple work-around would be to use libtomcrypt or 
libgcrypt instead of openssl. The drawback is that you wouldn't get ssl 
support. But this should work:

   bjam boost=source link=static runtime-link=static boost-link=static encryption=tommath

I'm not sure how to force boost-build to link dynamically against libdl, 
regardless of the <link> property.
