Wt

and when building with BOOST_DYNAMIC off I get only

libboost_thread-vc80-mt-1_46_1.lib(thread.obj) : error LNK2005: "bool __cdecl boost::this_thread::interruptible_wait(void *,struct boost::detail::timeout)" (?interruptible_waitthis\_thread@boost@YA_NPAXUtimeoutdetail@2@Z) already defined in boost_thread-vc80-mt-1_46_1.lib(boost_thread-vc80-mt-1_46_1.dll)

in wtdbo project (forgot to mention that in prev post, happens only in wtdbo too, everything else compiles normally)

Hello Alex,

I believe the key to the solution is that little thing you mention about including two versions of the boost libraries. It is clear that they clash; you're not supposed to do that.

Do you only have a problem when building with BOOST_DYNAMIC and SHARED_LIBS? Does a static Wt/Boost combination (=the default) give similar problems?

Wim.

Hello Wim! Thanks for reply. I've been stydying examples on 3.1.9 (compiled long time ago and not by me) on this PC today, but getting 3.2.1 to compile would be sweet.

The "out of the box" configuration works just fine - compiles without any errors and the result is a bunch of huge .lib files (wt.lib ~120Mb and wtd.lib ~240Mb for example) - is that size normal?..

Btw, tried to compile 3.1.11 half an hour ago - went almost flawlessly except one noncritical unresolved external (wmedia) but generally it compiles and works fine.

But when building 3.2.0 and 3.2.1 I get the clash between libboost_thread-vc80-mt-1_46_1.lib and boost_thread-vc80-mt-1_46_1.lib - is that because of an incorrect BOOST build? To build everything possible in boost 1.46.1 I used the following commands:

bjam -j2 ---build-type=complete ---layout=versioned ---toolset=msvc-8.0 threading=multi link=static runtime-link=static

bjam -j2 ---build-type=complete ---layout=versioned ---toolset=msvc-8.0 threading=multi link=static runtime-link=shared

bjam -j2 ---build-type=complete ---layout=versioned ---toolset=msvc-8.0 threading=multi link=shared runtime-link=shared

then I got

boost_module-vc80-mt-1_46_1.dll

boost_module-vc80-mt-gd-1_46_1.dll

boost_module-vc80-mt-gd.lib

boost_module-vc80-mt.lib

and

libboost_module-vc80-mt-1_46_1.lib

libboost_module-vc80-mt-gd-1_46_1.lib

libboost_module-vc80-mt-gd.lib

libboost_module-vc80-mt-s-1_46_1.lib

libboost_module-vc80-mt-s.lib

libboost_module-vc80-mt-sgd-1_46_1.lib

libboost_module-vc80-mt-sgd.lib

libboost_module-vc80-mt.lib

is that ok?

update:

got it working with BOOST_DYNAMIC=false, but still, it would be very educative to know why the linker doesn't like it when it's true?

edit: sigh I have to check things more carefully before posting. Went fine for release, but the problem persists for debug build (should the linker see boost dll's at all if BOOST_DYNAMIC=false?..)

mm, compiling the first example with the 3.2.1 gives

1>main.obj : error LNK2001: unresolved external symbol "struct Wt::WtLibVersion const Wt::WtWT_VERSION" (?WtWT_VERSIONWt@3UWtLibVersion1B)

(triple checked bin, include and lib paths - all pointing to the newly generated 3.2.1 :/) is that somehow related to the previous problems?..

update: I don't understand the dark magic behind this but adding

_CRT_NONSTDC_NO_WARNINGS

to preprocessor definitions solved all of the previously mentioned problems with boost when compiling WT... I took that one from a working project... It will take quite some time to study all the WT .h files to understand what is happening and why %)

Also, MSVS2005 compiles examples only when all of

WIN32

_WINDOWS

_CRT_NONSTDC_NO_WARNINGS

NOMINMAX

prep. defs are set for a project. Should I know those things before "jumping into the deep" or are they documented somewhere?

Hi Alex,

I succeeded in building Wt with BOOST_DYNAMIC and SHARED_LIBS.

Most of it at least, I still get errors in 3 projects (WtExt, WidgetGallery, and Test).

The 'Hello' example runs fine though.

I updated the following post with instructions:

http://redmine.webtoolkit.eu/boards/2/topics/3574

Hope this helps.

Note that I used VS 2008, as I do not have VS 2005.

Thank you for reporting; patches will be in git soon. I tested with MSVS 2008 and boost 1.50, building Wt DLLs using boost DLLs.
