problems with ./configure for libtorrent on linux - linux

Question

Hell I have been having an extremely tough time installing libtorrent and am unsure what the problems are. I have seen plenty similar errors online but the solutions were not helpful and I am pretty sure the error message is just too vague for comparison.
When I run ./configure I get
**

I then use the suggestion and the difference is that the bottom says
**
Checking for boost libraries:
checking for boostlib >= 1.36... yes
checking whether the Boost::System library is available... yes
checking for exit in -llib... no
checking for exit in -lboost_system-lib... no

**
the config.log file has an error
**

Any insight would be enormously appreciated

Answer 1

You need to install libboost-system.
If you are using Debian/Ubuntu, use apt-get as follows.
$ apt-get install libboost-system-dev
You may also need to install ...
$ apt-get install libboost-filesystem-dev libboost-thread-dev

Answer 2

The easiest way to install all the dependencies is with apt-get.
sudo apt-get build-dep python-libtorrent

Answer 3

I know this is a bit old, but to solve your OpenSSL problem you need to install the OpenSSL libraries with sudo apt-get install libssl-dev.

Answer 4

For CentOS users, you will want to install boost-devel.
# yum install boost-devel
But I still got the same error. Just want to point out one more thing, the CentOS 6.4 I work with had an old gcc compiler:
# g++ --version
g++ (GCC) 4.4.7 20120313 (Red Hat 4.4.7-3)
Copyright (C) 2010 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
Installing a newer version of gcc helped me to get rid of that particular error. I used g++ (GCC) 4.8.2 version and this time calling the following command worked:
# ./configure --with-boost-libdir=/usr/lib64
After this point you might still run into not finding openssl headers like the OP posted here, this post will help to overcome the error. You may have to install openssl-devel (for CentOS) or libssl-dev (for Debian), or you can run with
# ./configure --with-boost-libdir=/usr/lib64 --without-ssl
If you have openssl headers installed in your system, you don't need to use --with-openssl flag, or at least I didn't need to use it.
Although this is old post, hope it will help someone else like me.

Answer 5

To avoid OpenSSL issues you can build "libtorrent-rasterbar" disabling OpenSSL encryption.
For instance:
./configure --disable-debug --disable-encryption --prefix=/opt/libtorrent-rasterbar
And then "make" + "make install"

Answer 6

The accepted answer didn't work for me. What did work was editing the configure script file and removing those lines from it:
if test -z "$BOOST_SYSTEM_LIB"; then :
as_fn_error $? "Boost.System library not found. Try using --with-boost-system=lib" "$LINENO" 5
fi
Those lines seemed to check that the BOOST_SYSTEM_LIB environment variable exists and is not empty.

Answer 7

For Arch users (ex. Manjaro) install the boost pkg from pacman. Search for "boost" and install from Official Repo(extra).
