encfs / configure / libboost
I ran into an obscure Could not link against ! error when configuring
EncFS:
~/src$ apt-get source encfs
...
~/src$ cd encfs-1.7.4/
~/src/encfs-1.7.4$ ./configure
...
configure: WARNING: BOOST_CPPFLAGS -I/usr/include
checking whether the Boost::Serialization library is available... yes
configure: error: Could not link against !
That’s odd. And not immediately obvious how to fix.
For starters we need all the dependencies that Debian defines:
~/src/encfs-1.7.4$ sed -e '/^Build-Depends: /!d;s/^[^:]*: //;s/([^)]*)//g;s/,//g' \
debian/control
debhelper librlog-dev librlog5 libfuse-dev libssl-dev pkg-config
libboost-serialization-dev libboost-filesystem-dev quilt dh-autoreconf
~/src/encfs-1.7.4$ sudo apt-get install `sed -e
'/^Build-Depends: /!d;s/^[^:]*: //;s/([^)]*)//g;s/,//g' debian/control`
...
And then we need to supply the libboost directory explicitly:
~/src/encfs-1.7.4$ ./configure --with-boost-libdir=/usr/lib/x86_64-linux-gnu
...
configure: WARNING: BOOST_CPPFLAGS -I/usr/include
checking whether the Boost::Serialization library is available... yes
checking for exit in -lboost_serialization... yes
checking whether the Boost::Filesystem library is available... yes
...
Profit!
