Re: [Ekiga-devel-list] [Win32] libboost compiling - trouble with opal

[Michael Rickmann <mrickma gwdg de>]

Hallo,
yes I have succeded with your instructions, but the outcome is not quite 
what I think that we need. Two of the compiler flags are wrong we need 
1) -mthreads instead of -pthreads and 2) -gstabs instead of -g .
Point 1) can be overcome by changing user-config.jam to
using gcc : : i586-mingw32msvc-g++ : ;
toolset.add-requirements
  <toolset>gcc:<target-os>windows
  <toolset>gcc:<threadapi>win32 ;
2) we would need to have across DLL debugging with our Mingw in a debug 
version of boost_signals.dll. I have spent now more than a day digging 
in the build process of libboost to achive that, failing. The build 
seems rather stand alone. As we only need boost_signals.dll in a release 
and debug version I definetely prefer a hand crafted Makefile and download.

Moreover, before I could get your instructions working I had to 
uninstall Jaunties bjam and boost stuff. Although I got boost somewhat 
integrated into the Makefile

### libBOOST++
update-sources::
	echo --- Getting libBOOST++ ...
	$(WGET) -P src $(BOOST_URL)/$(BOOST_ARCHIVE)

$(BOOST_DIR)/user-config.jam: $(SRCDIR)/$(BOOST_ARCHIVE)
	tar xfj $(SRCDIR)/$(BOOST_ARCHIVE)
	( cd $(BOOST_DIR) ; CC=gcc; CXX=g++; ./bootstrap.sh --prefix=$(BUILDROOT) )
	echo "using gcc : : i586-mingw32msvc-g++ : ; toolset.add-requirements \
	<toolset>gcc:<target-os>windows <toolset>gcc:<threadapi>win32 ;" > 
$(BOOST_DIR)/user-config.jam

$(LIBDIR)/$(BOOST_LIB): $(BOOST_DIR)/user-config.jam
	( cd $(BOOST_DIR) ; ./bjam -d+2 --user-config=user-config.jam 
--layout=system  --with-signals \
	variant=release threading=multi link=shared runtime-link=shared 
toolset=gcc stage install )

I think that the outcome is not satisfactory.
Regards
Michael
