Lars,

thanks for your answer. I will try your proposal, we only have static libs which we assemble into an executable. So boost log should be fine here. I also link filesystem etc, but not dl. May be that is the error.

I will try it.

Thanks, Ovanes

Hi *,

I am stuck with a problem to link on linux (ubuntu 12.04) with a boost log library (clang 3.0 & libstdc++).

No matter what I do it fails. The problem is:

I have a 3rd party library which is delivered as an .so-module and I need to link with it. My project is organized so that we develop static libraries and link them with test or application runner executables.

I currently build boost as static libraries only, after I link my

And so on. Do you have any hints or suggestions?

No matter which platform you target, static libraries have the amusing property that they're pretty much a lump of object files, and as such, are not linked to any libraries at build time.

Thus, you need to link to any libraries that Boost.Log uses when you link to a static Boost.Log. Judging by your errors, this would be -lboost_filesystem, -ldl and possibly building with -pthread, depending on your toolchain.

Also note that if you use Boost.Log in more than one module (DLL, shared object), you need to use the shared Boost.Log library as indicated by the documentation [1].

Eric, thanks for the suggestion. I just switched to dynamic version and everything is fine now. I really can't await C++ modules and hope they will fix that sort of a problem... On Wed, Nov 20, 2013 at 8:02 PM, Eric Prud'hommeaux wrote:

Unfortunately, still had no luck to link the logging library under linux.

Please find the list of libraires my application links with:

System Libs ========= pthread rt dl

Boost Libs ======== system${boost_suffix} filesystem${boost_suffix} date_time${boost_suffix} program_options${boost_suffix} chrono${boost_suffix} thread${boost_suffix} log${boost_suffix} log_setup${boost_suffix}

boost_suffix is -mt. Defining the -DBOOST_LOG_DYN_LINK option makes the linker to only miss the logger library symbols. I assume, because everything else is expected to be within the missing implementations....

It looks below like the linker isn't finding your static build of the logger. Maybe (outside shot) you need to add an object which instantiates a trivial logger to get some of the template functions below.

I doubt it will help, but just in case, before boost::log was integrated into the main boost distro, I linked to my app with something like:

LIBINC += -L$(BOOST_TARGET)lib $(LINK_BOOST_LOG) -lboost_thread$(BOOST_SUFFIX) -lboost_filesystem$(BOOST_SUFFIX) -lboost_system$(BOOST_SUFFIX) -lboost_date_time$(BOOST_SUFFIX)

Lars,

thanks for your answer. I will try your proposal, we only have static

which we assemble into an executable. So boost log should be fine here. I also link filesystem etc, but not dl. May be that is the error.

I will try it.

Thanks, Ovanes

Hi *,

I am stuck with a problem to link on linux (ubuntu 12.04) with a boost log library (clang 3.0 & libstdc++).

No matter what I do it fails. The problem is:

I have a 3rd party library which is delivered as an .so-module and I need to link with it. My project is organized so that we develop static libraries and link them with test or application runner executables.

I currently build boost as static libraries only, after I link my

And so on. Do you have any hints or suggestions?

No matter which platform you target, static libraries have the amusing property that they're pretty much a lump of object files, and as such, are not linked to any libraries at build time.

Thus, you need to link to any libraries that Boost.Log uses when you link to a static Boost.Log. Judging by your errors, this would be -lboost_filesystem, -ldl and possibly building with -pthread, depending on your toolchain.

Also note that if you use Boost.Log in more than one module (DLL, shared object), you need to use the shared Boost.Log library as indicated by the documentation [1].

Mostafa, thanks for the suggestion. We are using CMake and develop for Mac OS X and Linux. This was a port of our software to Linux ;) So first time is always hard.... Now it builds and should stay so. I had to fix various settings in CMake files for Linux/clang/libstdc++ build. On Wed, Nov 20, 2013 at 10:14 PM, Mostafa wrote:

thanks for the suggestion. I just switched to dynamic version and everything is fine now.

I really can't await C++ modules and hope they will fix that sort of a problem...

You might want to look into using Gnu Autotools if you're just targeting Linux. They do simplify the whole static/shared library linking.
