[ovirt-users] Compiling oVirt for Debian.

Fri Apr 21 18:15:59 UTC 2017

Have run into difficulties building ovirt-host-deploy. I tried to
build otopi using the commands given in the INSTALL file and made sure
to run `./configure` with the options --enable-java-sdk and
--with-maven. Unfortunately, when I restarted the building of
ovirt-host-deploy, I failed to make it past ./configure with the
resulting error below:

configure: error: otopi-devtools required but missing

I've run ./configure with the options and without it, and I've got the
same error. Sandro in IRC had suggested that I adapt the full options
for ./configure in Fedora and use them in Debian. Those are as
follows:

 ./configure --build=x86_64-redhat-linux-gnu
--host=x86_64-redhat-linux-gnu --program-prefix=
--disable-dependency-tracking --prefix=/usr --exec-prefix=/usr
--bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc
--datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib64
--libexecdir=/usr/libexec --localstatedir=/var
--sharedstatedir=/var/lib --mandir=/usr/share/man --info
--docdir=/usr/share/doc/otopi-1.6.3 --disable-python-syntax-check
--enable-java-sdk --with-local-version=otopi-1.6.3-0.0.master.fc26
COMMONS_LOGGING_JAR=/usr/share/java/commons-logging.jar
JUNIT_JAR=/usr/share/java/junit.jar

I got stuck at `--build=x86_64-redhat-linux-gnu` since `uname -a`
gives: Linux localhost 4.6.0-1-amd64 #1 SMP Debian 4.6.2-2
(2016-06-25) x86_64 GNU/Linux
I wasn't sure if I should substitute `x86_64-redhat-linux-gnu` with
`x86_64-gnu-linux`. Also the ./configure script downloaded
otopi-1.7.0.master so that I would need to change that as well as the
reference to Fedora in
`--with-local-version=otopi-1.6.3-0.0.master.fc26`. I went onto the
#debian-next channel and was advised to spare myself future pain by
looking into packaging the necessary stuff for Debian instead of
trying to hack out a build that will be painful to maintain in future.

Pointers, docs, advice are all welcome.
