Linux Question

problems with ./configure for libtorrent on linux

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

**

Building libtorrent-rasterbar 0.16.5

Checking for a C/C++ compiler to use:
checking for gcc... gcc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executables...
checking whether we are cross compiling... no
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ISO C89... none needed
checking how to run the C preprocessor... gcc -E
checking whether gcc and cc understand -c and -o together... yes
checking for g++... g++
checking whether we are using the GNU C++ compiler... yes
checking whether g++ accepts -g... yes

Checking for boost libraries:
checking for boostlib >= 1.36... yes
checking whether the Boost::System library is available... yes
configure: error: Boost.System library not found. Try using --with-boost-system=lib


**

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
configure: error: Could not link against boost_system-lib !


**

the config.log file has an error

**

configure:16572: result: no
configure:16537: checking for exit in -lboost_system-lib
configure:16562: gcc -o conftest -lpthread -g -O2 -fvisibility=hidden -I/usr/include -L/usr/lib conftest.c -lboost_system-lib -lpthread >&5

Any insight would be enormously appreciated

Answer

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
