Could you tell me more?

He told more in a private email : I'm wondering if it isn't a problem with the m4 macro used to detect boost -- that they haven't been tested for cross-compilation.

I'll have to investigate.

I made some tests bypassing configure test. I had the same error messages.

After quite some time I tried to compile Ekiga master and also have some difficulties with boost. I think moving to boost will improve Ekiga in the long term. Currently it blocks the Win32 port. The libboost pointers are header only but libboost signals require a compiled lib. Without becoming an expert in Boost-Build, cross compiling may result in something not really safe, and because of name mangling differences we can not use one of the MSVC precompiled packages. So I tried to compile a mini-dev under Windows using MinGW: . The lib is gcc-4.4.0 compiled, so the debug format of the ..-d.dll and ..-d.dll.a is not compatible with what we currently use - new gcc-mingw32 packages are already in Debian sid. For passing Ekiga's configure libboost signals test extract the archive into BUILDROOT and add --with-boost=$(BUILDROOT) to the confekiga:= portion of the Win32 Makefile. Then configure should print
checking for boostlib >= 1.34... yes
checking whether the Boost::Signals library is available... yes
checking for exit in -lboost_signals-d.dll... yes

Next compilation fails for videooutput-manager-dx.cpp. I feel not fit enough to interpret the 67 kB long error log (attached). Certainly the source file is not used for linux and when comparing the code to videooutput-manager-x.cpp the -dx.cpp has a number of nested (boost::bind (boost::bind (... which the -x.cpp does not have. Making them single "(boost::bind ... this, ..." lets compilation proceed. As I am not fit in boost signals I will not provide a patch.

Next error occurs while linking ekiga.exe:

Is there another boost lib which has to be compiled?
