RE: [Boost-users] building boost on vc7.1 with stlport

16 Jul 2004

      I finally compiled the whole thing (by enabling wchar_t builtin support...)
and I ran into the same problem I had before: when I try to USE the regex
class in my code I get the following 2 linker errors:

html to mhtml.obj : error LNK2019: unresolved external symbol "public:
__thiscall boost::reg_expression::reg_expression(char const
*,unsigned int,class _STL::allocator<char> const &)"
(??0?$reg_expression@DV?$regex_traits@D@boost@@V?$allocator@D@_STL@@@boost@@
QAE@PBDIABV?$allocator@D@_STL@@@Z) referenced in function "public:
__thiscall boost::basic_regex::basic_regex(char const
*,unsigned int,class _STL::allocator<char> const &)"
(??0?$basic_regex@DV?$regex_traits@D@boost@@V?$allocator@D@_STL@@@boost@@QAE

boost::basic_regex::~basic_regex(void)"
(??1?$basic_regex@DV?$regex_traits@D@boost@@V?$allocator@D@_STL@@@boost@@QAE
@XZ)

Do I have to link manually to something? I thought that's already done in
the headers...
(and I'm still curious as to how one should build boost in vc7.1 with
stlport. Maybe someone should make a faq or something...)

i first compiled (succesfully) stlport 4.6.2.
then i ran "bjam "-sTOOLS=vc7.1-stlport" install" and it 
failed compiling
the regex library.
then i manually went to the libs\regex\build folder and ran 
"nmake /f
vc7.1-stlport clean install" and it compiled the first 
thing ok and the
2nd
time around threw a LOT of linker errors (well, only ~49, 
but they're
stl-style-long :D). I set correctly the STLPORT_VERSION and the
STLPORT_PATH
env vars, the tools were loaded ok, the INCLUDE env var had 
stlport's
include dir first... AND IT COMPILED OK the first one... here's a
screenshot
of the last page of errors. please help me...
I think this is a problem with mis-matched /Zc:wchar_t 
options - Boost is
normally built with that flag on, while STLPort is normally 
built with it
off.  Depending on how you intend to build your own code, 
either rebuild
STLPort with /Zc:wchar_t or use:
bjam -sTOOLS=vc7.1-stlport -sBUILD="off"
In fact this is the default setting, and having double 
checked it works for
me without having to mess with the BUILD variable, have you changed
something else somewhere?  I can reproduce the makefile 
problem though, I'll
get that fixed.
John.
