Re: [Boost-users] filesystem/signals/serialization dlls not linking

The reason that this appears to be happening is that in 1_33_1 the link 
line for these libraries includes -L"" .  The empty quotes get ignored 
and the following file is incorrectly to be taken to be a directory and 
its symbols don't get linked in.  Here it is in context:

"g++"   "-Wl,--enable-auto-image-base" "-Wl,--exclude-symbols,_bss_end__:_bs
s_start__:_data_end__:_data_start__"  
"-Wl,--out-implib,bin\boost\libs\filesyste

This does not happen in 1_33_0.  Can anyone tell me how to work around 
it?  Would it be possible to fix this in the next boost release?

Thanks.
