# libopenmpt Debian backport info
|
||
|
|
|
||
|
|
Backported libopenmpt 0.4.0 packages are available at ppa:stjr/srb2
|

|
for Ubuntu Disco, Cosmic, Bionic, Xenial, and Trusty as of 2019/01/04.
|
||
|
|
|

# Backporting from Disco to Cosmic and Bionic
|
||
|
|
|
||
|
|
Cosmic and Bionic require no changes to the source package. They have
|
||
|
|
the prerequisite `debhelper` and `dpkg-dev` versions, a matching
|
||
|
|
`automake` version (1.15), as well as G++ > 5.
|
||
|
|
|
||
|
|
Use the `backportpackage` script to automatically tag the package to
|
||
|
|
Cosmic and Bionic, then upload to PPA:
|
||
|
|
|
||
|
|
```
|
||
|
|
sudo apt install ubuntu-dev-tools
|
||
|
|
export UBUMAIL="John Doe <email@com.com>" # Name and email associated with your PGP sign key
|
||
|
|
backportpackage -d [cosmic/bionic] -u [path-to-ppa] --key=[key-fingerprint] http://archive.ubuntu.com/ubuntu/pool/universe/libo/libopenmpt/libopenmpt_0.4.0-1.dsc
|
||
|
|
```
|
||
|
|
|
||
|
|
# Backporting from Disco to Xenial
|
||
|
|
|
||
|
|
Download the package:
|
||
|
|
|
||
|
|
```
|
||
|
|
dget http://archive.ubuntu.com/ubuntu/pool/universe/libo/libopenmpt/libopenmpt_0.4.0-1.dsc
|
||
|
|
```
|
||
|
|
|
||
|
|
Xenial has an earlier `debhelper` version, but the rest of the prerequisites
|
||
|
|
are available.
|
||
|
|
|
||
|
|
The required changes (see patch `debian/libopenmpt-0.4.0-xenial-backport.diff` in this directory):
|
||
|
|
|
||
|
|
* `debian/control`
|
||
|
|
* Add `automake` to Build-Depends
|
||
|
|
* Change `debhelper` version to `(>= 9.0~)`
|
||
|
|
* `debian/compat`
|
||
|
|
* Change to `10`
|
||
|
|
|
||
|
|
Then run these commands:
|
||
|
|
|
||
|
|
```
|
||
|
|
dch -i # Edit the changelog; make sure the Name and email match the PGP sign key and that the changelog targets xenial
|
||
|
|
debuild -s -d -k0x[key-fingerprint] # Build the updated package
|
||
|
|
dput [path-to-ppa] [path-to-changes-file] # Upload to PPA
|
||
|
|
```
|
||
|
|
|
||
|
|
# Backporting from Disco to Trusty
|
||
|
|
|
||
|
|
Download the package:
|
||
|
|
|
||
|
|
```
|
||
|
|
dget http://archive.ubuntu.com/ubuntu/pool/universe/libo/libopenmpt/libopenmpt_0.4.0-1.dsc
|
||
|
|
```
|
||
|
|
|
||
|
|
Trusty requires more changes because it uses G++ 4.8 whereas the source
|
||
|
|
package expects G++ >= 5. Automake is an earlier version as well --
|
||
|
|
1.14 vs 1.15 -- so `autoreconf` needs to be run at build time.
|
||
|
|
|
||
|
|
The required changes (see patch `debian/libopenmpt-0.4.0-trusty-backport.diff` in this directory):
|
||
|
|
|
||
|
|
* `debian/control`
|
||
|
|
* Add `automake` and `libtool` to Build-Depends
|
||
|
|
* Change `debhelper` version to `(>= 9.0~)`
|
||
|
|
* Change `dpkg-dev` version to `(>= 1.17.0)`
|
||
|
|
* `debian/compat`
|
||
|
|
* Change to `10`
|
||
|
|
* `debian/rules`
|
||
|
|
* Under `override_dh_auto_configure`, input this line as the first command:
|
||
|
|
`autoreconf --force --install`
|
||
|
|
* This re-configures the package for Automake 1.14
|
||
|
|
* `debian/libopenmpt-modplug1.symbols` and `debian/libopenmpt0.symbols`
|
||
|
|
* Delete these files
|
||
|
|
* The C++ ABI for G++ 4.8 is incompatible with G++ >= 5, so the
|
||
|
|
generated symbols will be different than the expected symbols
|
||
|
|
in the `*.symbols` files. Deleting these files will skip the
|
||
|
|
symbol check.
|
||
|
|
|
||
|
|
Then run these commands:
|
||
|
|
|
||
|
|
```
|
||
|
|
dch -i # Edit the changelog; make sure the Name and email match the PGP sign key and that the changelog targets trusty
|
||
|
|
debuild -s -d -k0x[key-fingerprint] # Build the updated package
|
||
|
|
dput [path-to-ppa] [path-to-changes-file] # Upload to PPA
|
||
|
|
```
