[Gnash-dev] linker error

[dww]

I would appreciate an answer to the following question:

When building the latest Cygnal I got the following linker errors

libnet/.libs/libgnashnet.so: undefined reference to
`boost::gregorian::greg_month::as_short_string() const'
libnet/.libs/libgnashnet.so: undefined reference to
`boost::gregorian::greg_weekday::as_long_string() const'

When I changed the following line in the Cygnal directory makefile
generated by the configure process:

BOOST_CYGNAL_LIBS =  -lboost_serialization-gcc42-1_34_1
-lboost_date_time-gcc42-1_34_1

to

BOOST_CYGNAL_LIBS =
-lboost_serialization-gcc42-1_34_1 /usr/lib/libboost_date_time-gcc42-1_34_1.a

then it linked OK

/usr/bin is in my PATH environmental so then why did  I have to make
this change or am I missing something in the configure step?

Thank you.

Dennis
