[tahoe-dev] Fwd: that problem with comparing types across DLLs

[Zooko Wilcox-O'Hearn]

Thanks, Wei Dai.  I'll ask the Debian and Fedora packaging experts  
what they think.

Here is the list of files included in the libcrypto++-dev package in  
Debian stable:

http://packages.debian.org/lenny/amd64/libcrypto++-dev/filelist

It does include libcryptopp.a.  I'll try linking against that.

Dear Debian and Fedora packaging experts: please see Wei Dai's  
message below.  He is the author of Crypto++.

Does anyone know how to specify that the "-lcryptopp" on your g++  
command line should use the static lib in preference to the dynamic one?

Regards,

Zooko
