[Boost-users] [Boost.Log] How to link with on MSVC 2008?

[RUOFF, LARS (LARS)** CTR **]

Hello,

i have found the following instructions to build Boost.Log:

 

> Boost.Log can be compiled by:

>

> 1. Getting 1.42 source release

> 2. Unpacking Boost.Log on top of it

> 3. Following the usual procedure:

>

> .\bootstap.bat

> .\bjam --with-log

 

I did the above starting from a 1.44 source release.

This worked out well.

 

But when trying to use the library I get a lot of linker errors in my project:

 

1>Linking...

1>libboost_log-vc90-mt-gd-1_44.lib(text_file_backend.obj) : error LNK2019: unresolved external symbol "class boost::filesystem2::file_status [...]

(Very long error messages containing decorated names. The above is just the start)

 

Linker path settings should be correct, since the linker correctly finds libboost_log-vc90-mt-gd-1_44.lib.

Also the project is using other Boost libraries (Asio, shared-ptr, bind, posix-time, etc) without problems.

 

Anyone managed to compile and use Boost.Log on MSVC 2008 and can help?

Thank you,

Lars Ruoff

Just a guess: Log depends on Boost.Filesystem library, and you haven't
compiled it.

No,
Because I just made a test:
When I use stuff from Boost.Filesystem
Like
boost::filesystem::remove_all( "foobar" );
boost::filesystem::create_directory( "foobar" );
it links well.

Any other ideas?
Did anyone manage to link with Boost.Log on a MSCV 2008 project?
How did you compile the library?

Regards,
Lars

Can you compile/link the Boost.Log trivial example?

Ok, well, i got this working now.
Thanks for your input Roger - it put me back on track!

The things is:

#include <boost/log/trivial.hpp>
BOOST_LOG_TRIVIAL(trace) << "A trace severity message";

(like in the trivial tutorial)
gives me the linker errors (but compiles ok).

But with additionally including
#include <boost/filesystem.hpp>
it will link ok.

Anyone know why?

All I can guess, without seeing the errors, is that the Log library will create a file with the name of the process for storing the information. So I can see why it would need the boost filesystem but not sure why linking errors are resolved by including the header. Can you post the linker error?

Hi,
I posted part of it in my first message.
Here's the complete messages (some are really long) attached as a txt file.
