Subject: Re: [Bitcoin-development] Announcement: libcoin
Precedence: list

I tried on another 11.10 machine with the normal boost 1.42 and things =
also worked as they should.

However, I noticed a difference between your cmake output and mine:

> -- Found OpenSSL: /usr/lib/libssl.so;/usr/lib/libcrypto.so=20

-- Found OpenSSL: =
/usr/lib/i386-linux-gnu/libssl.so;/usr/lib/i386-linux-gnu/libcrypto.so =
(found version "1..")

Are you sure that the openssl libraries/includes found are the correct =
ones ? cmake finds your openssl libraries at /usr/lib/ which most likely =
will make it think that the includes are at /usr/include. I can see that =
at least X11 stuff is in /usr/lib/x386-linux-gnu like my openssl.

Could there be an issue there ?

SHA256 would normally be found in openssl/sha.h but if that is somehow =
corrupt ?

Cheers,

M

PS: to get more debug output, please try a "make VERBOSE=3D1" That will =
show what g++ flags that are used, and might help us.
