Hello,
Some remarks/questions concerning Celix:
1. For several applications, I need to select and follow a service, based
on its properties. In the current service tracker implementation, on service
creation, one can only give the service class name as a parameter. In the Felix
(java OSGi) implementation one can, alternatively, give a LDAP filter as
parameter. The full Felix interface needs to be provided in Celix.
2. The processing of a bundle's manifest file (in celix) is not robust
for whitespace and lacking carriage returns, e.g. in the Services-Import/Export
lists. I don't know whether the OSGi spec says something about this, but it
would save the developers a lot of time when robustness was built in.
3. In some OSGi applications a resource file is used, see e.g. the paint
example of the book "OSGi in Action". Here some .png files are used in the
application to display icons on a user interface. In the book "OSGi in Action"
it is possible to get resources through the bundle object, see listing 3.17 of
"OSGi in action". Is the resource interface already implemented in Celix?
4. I have implemented some of the easier examples of the book 'OSGi in
action' (that concerns Felix, a java implementation of OSGi) in celix. I have
sent the code to 'celix' and hope that these will be provided in celix's svn
repository in the near future.
5. In the Celix environment, cmake is used for building. I have an
implementation of the paint-example in Celix, that uses the GDK environment as
an external library. In the makefiles of GDK applications, one generally uses
the 'pkg-config' tool to find information about include-files and libraries of
GDK. In cmake one can use the FindPkgConfig macro, by adding the following
lines:
include(FindPkgConfig)
...
pkg_search_module(GLIB REQUIRED glib-2.0)
pkg_search_module(GTHR REQUIRED gthread-2.0)
pkg_search_module(GTK REQUIRED gtk+-2.0)
...
include_directories(${GTK_INCLUDE_DIRS})
include_directories (${GLIB_INCLUDE_DIRS})
include_directories (${GTHR_INCLUDE_DIRS})
...
link_directories(${GTK_LINK_DIRS})
link_directories (${GLIB_ LINK_DIRS})
link_directories (${GTHR_ LINK _DIRS})
...
target_link_libraries(${_targetname} pthread ${GLIB_LIBRARIES} ${GTK_LIBRARIES}
${GTHR_LIBRARIES})
Under MacOS, cmake has some problems using the
link directories, communicated in the 'link_directories()' commands in the
'target_link_libraries()' command. The 'pkg_search_module()' finds the correct
link directories. I need to look deeper in this problem, but maybe someone
already has experience with cmake files and knows the solution to the problem.
