[Cppcms-users] Problems after upgrading cppcms with booster

[augustin <aug...@ov...>]

I was using a much older version of cppcms (from the temporary branch, before 
it was moved to trunk).

I downloaded from svn a fresh copy of cppcms from the trunk.
cmake ..
make
make test
sudo make install
All without any problem.

But now, my own application won't compile anymore. I deleted the build 
directory of my app, and rebuild from scratch, but I get the following errors: 


/usr/lib/gcc/x86_64-linux-gnu/4.4.1/../../../../lib/libcppcms.so: undefined 
reference to `booster::locale::generator::get(std::basic_string<char, 
std::char_traits<char>, std::allocator<char> > const&) const'

collect2: ld returned 1 exit status


libbooster.so.0.0.0
and
libcppcms.so.1.0.0
are all properly installed in /usr/local/lib as before, but with today's 
timestamp.


Actually, I had tried to upgrade cppcms earlier, but got a similar error and 
reverted to using the older cppcms.


I added 'booster' to my target_link_libraries() in CMakeLists.txt (it seems it 
was not required in earlier versions of cppcms).
I deleted the build directory and started again...
But now, there are compiler errors about the template object:


Linking CXX executable ../my_app.fcgi
CMakeFiles/../my_app.fcgi.dir/view.cpp.o: In function `void 
booster::locale::message::write<char>(std::basic_ostream<char, 
std::char_traits<char> >&) const':

`booster::locale::ios_info::domain_id() const'
collect2: ld returned 1 exit status

where view.cpp is generated by cppcms_tmpl_cc from my template.
