This commit removes the dependencies on MMU and dynamic libraries. In order to build v4l2 utilities such as compliancy tools like v4l2-compliance or cec-compliance, v4-utils can now be built without dynamic libraries support. In that case the v4l-utils parts which depends on dynamic library support are not built: - libv4l & libv4lconvert libraries - libv4l plugins - rds-ctl utility - contrib test utilities The rest of the utilities are built.

Subject: [PATCH] configure.ac: add --disable-libv4l option
|
|
|
|
Add an option to disable libv4l libraries and plugins compilation.
|
|
If system is not supporting dynamic shared libraries, this option
|
|
is automatically set.
|
|
dlopen() is no more a mandatory dependency (warning is kept).
|
|
lib/ and contrib/ folders are no more built with this option set
|
|
because of libv4l dependency.
|
|
utils/ folder is still built with this options set but without
|
|
rds-ctl because of its libv4l dependency.
|
|
v4l2-compliance and v4l2-ctl are also built but without any links
|
|
on libv4l and libv4lconvert libraries.
