you are doing this over WIFI and experiencing glitches, the wireless is the

first suspect.

=== Building the OpenHome libraries
|
|
|
227 |
|
|
|
228 |
Building the Openhome libraries is a bit of a black art for a number of
|
|
|
229 |
understandable reasons:
|
|
|
230 |
|
|
|
231 |
- There are no released distributions for the OpenHome libraries, but
|
|
|
232 |
only a number of git repositories for the different components. The state
|
|
|
233 |
of the repositories is not completely consistent at all times (there will
|
|
|
234 |
be moments when a component will not build with another).
|
|
|
235 |
- The OpenHome build system is very complicated because it works on
|
|
|
236 |
multiple platforms and multiple language bindings.
|
|
|
237 |
|
|
|
238 |
The *sc2mpd* source comes with a shell script named _ohbuild.sh_ to help
|
|
|
239 |
with this. It has several functions:
|
|
|
240 |
- Cloning the OpenHome and checking out verified revisions
|
|
|
241 |
- Applying a few minor patches to ensure that the build will work in a
|
|
|
242 |
simplified environment (e.g. without a c# compiler).
|
|
|
243 |
- Creating a tar file of a compact trimmed tree.
|
|
|
244 |
- Running the build either from the cloned tree or the tar file.
|
|
|
245 |
|
|
|
246 |
The tar functions are mostly useful to help with building packages. For a
|
|
|
247 |
normal build, the procedure would be as follows:
|
|
|
248 |
|
|
|
249 |
cd sc2mpd
|
|
|
250 |
mkdir /my/place/for/openhome
|
|
|
251 |
sh ohbuild.sh -b /my/place/for/openhome
|
|
|
252 |

Building the Openhome libraries is a bit of a black art, and the *sc2mpd*
|
266 |
Once OpenHome is built and the auxiliary library development packages are
|
| 232 |
source comes with an _ohbuild.sh_ script which will try to clone the
|
|
|
| 233 |
Openhome Git repositories and build the libs:
|
|
|
| 234 |
|
|
|
| 235 |
cd sc2mpd
|
|
|
| 236 |
mkdir /my/place/for/openhome
|
|
|
| 237 |
sh ohbuild.sh /my/place/for/openhome
|
|
|
| 238 |
|
|
|
| 239 |
Miscellaneous error messages will be displayed during the build. Hope for
|
|
|
| 240 |
the best...
|
|
|
| 241 |
|
|
|
| 242 |
|
|
