using the linker options:

/O2 /Ob2 /I "C:\Cpp\boost_1_35_0" /I ...
/D "WIN32" /D "_WINDOWS" /D "NDEBUG" /D "BOOST_ENABLE_ASSERT_HANDLER=1"
/D "QT_DLL" /D "QT_GUI_LIB" /D "QT_CORE_LIB" /D "QT_NO_DEBUG" /D

/Fo"eda.dir\Release\\" /Fd"D:/work/build/Release/eda.pdb" /W3 /nologo /c
/TP /errorReport:prompt

Any ideas what happened here?

Thanks,

maybe also of interest the compiler options:

Hi!

What is project organization? Usually this means that you use multiple dlls,
which export same symbols.

You're linking against both static and shared library at the same time.Can't
work.

CMake running wild ? Look at FindBoost.cmake what went wrong. And most
probably disabled autolinking or add BOOST_ALL_DYN_LINK if you want shared
libs. Take a look at the getting started guide for more tips.

BTW, it's better to use English locale so that your errors message are clear
to everybody.

It appears that one part of your applications links to libboost_program_options-vc80-mt-1_35.lib
(static library) while another links to boost_program_options-vc80-mt-1_35.lib (import lib).
The only reason I can imagine for that is that parts of your applications are built with
different settings -- in particular BOOST_ALL_DYN_LINK macro. Try cleaning everything,
making sure that macro is set the the same value everywhere, and try again.

Thanks to all answers, I'm using really cmake. Obviously I have to go
more into the deep since the cmake macro does a bad job here. Define
BOOST_ALL_DYN_LINK works for this time since I want static linkage.

<OT>
How can I set the English locale for MSVC compiler cl.exe inside VS IDE?
which should be in current locale.
</OT>

Thanks,
Olaf

BOOST_ALL_DYN_LINK is for dynamic linking
But what is the macro for All Static linking ?

I've used BOOST_ALL_STATIC_LINK
I've declared my path to the static libs,
And also, I have the errors :
Error 2 error LNK2005: "public: class std::basic_string<char,struct
std::char_traits<char>,class std::allocator<char> > & __thiscall
std::basic_string<char,struct std::char_traits<char>,class

std::char_traits<char>,class std::allocator<char> > const &)"

@***@ABV01@@Z) already defined in
libboost_filesystem-vc80-mt-sgd-1_35.lib(operations.obj) msvcprtd.lib
[...]

And what's more this error :
Error 26 fatal error LNK1104: cannot open file
'libboost_filesystem-vc80-mt-gd-1_35.lib' makePatch


Why is it still searching a dynamic lib ??? nevermind dynamic libs !!!

I have only 7 files in my program, it's not complicated to check all.

What is the boost concept of autolink ?

My static libs have been installed by the exe distributed with all libs
(static dyn, debug not debg.. and so on)
