OK. I didn't want to give too much details in the end, but you're right. > Certainly, the fact that the target installation path is suffixed with > -pure > should be clarified. > > Do all the packages that depend on directfb still build correctly with > this > -pure suffix? The public library is not moved: /usr/lib/libdirectfb.so Only internal libraries are placed in a different directory: /usr/lib/directfb-x.y.z-pure/ It contains following directories: gfxdrivers, inputdrivers, interfaces, systems, wm. It makes no difference for applications using DFB. Would you be satisfied with that description below, as a commit message? DirectFB provides two options for debug: * --enable-debug-support (default is yes) * --enable-debug (default is no) The first one provides the functions to print debug information. These functions can be called inside DirectFB, or by an external DirectFB driver in another package. The second one enables verbose mode in DirectFB, using these functions. Buildroot currently provides an option for the second one only. The first one - which is necessary for the second one - is always enabled, because this is the default value. The new option (BR2_PACKAGE_DIRECTFB_DEBUG_SUPPORT) makes it possible to disable debugging support (--disable-debug-support) in order to build the library with no debug feature at all. When debugging support is disabled, the target installation path of internal libraries (/usr/lib/directfb-) is suffixed with -pure. The public library (/usr/lib/libdirectfb.so) remains unchanged. Some external DirectFB drivers will install in /usr/lib/directfb--pure in release mode. For that reason, it is important that DirectFB can be configured to use this directory. -- C?dric
