I trying to create a package am335x-pru-support which creates a shared library used by another package pru-examples. The library files installed with am335x-pru-support are (from <BUILD>/image) -rwxr-xr-x 4 gthomas gthomas 17074 Feb 27 13:40 usr/lib/libprussdrv.a lrwxrwxrwx 1 gthomas gthomas 16 Feb 27 13:40 usr/lib/libprussdrv.so -> libprussdrv.so.1 lrwxrwxrwx 1 gthomas gthomas 18 Feb 27 13:40 usr/lib/libprussdrv.so.1 -> libprussdrv.so.1.0 -rwxr-xr-x 1 gthomas gthomas 22092 Feb 27 13:40 usr/lib/libprussdrv.so.1.0 -rw-r--r-- 4 gthomas gthomas 8074 Feb 27 13:40 usr/include/pruss/prussdrv.h -rw-r--r-- 4 gthomas gthomas 4286 Feb 27 13:40 usr/include/pruss/pruss_intc_mapping.h
These files are split by the packager as: gthomas@europa:packages-split$ find am335x-pru-support | sort am335x-pru-support am335x-pru-support/usr am335x-pru-support/usr/lib am335x-pru-support/usr/lib/libprussdrv.so.1 am335x-pru-support/usr/lib/libprussdrv.so.1.0 gthomas@europa:packages-split$ find am335x-pru-support-dev | sort am335x-pru-support-dev am335x-pru-support-dev/usr am335x-pru-support-dev/usr/include am335x-pru-support-dev/usr/include/pruss am335x-pru-support-dev/usr/include/pruss/prussdrv.h am335x-pru-support-dev/usr/include/pruss/pruss_intc_mapping.h am335x-pru-support-dev/usr/lib am335x-pru-support-dev/usr/lib/libprussdrv.so These files get staged correctly to pru-examples recipe-specific-sysroot and I can build and link against them, using DEPENDS="am335x-pru-support". The problem is that when my build (target recipe) uses $(CC) my_target_program.c $(LDFLAGS) -lprussdrv it gets satisfied by /usr/lib/libprussdrv.so and not /usr/lib/libprussdrv.so.1 This in turn appears to keep the pru-examples package from having a runtime dependency against the am335x-pru-support package and the necessary library file does not end up on my target. I've tried to work through this, following many recipes as examples, e.g. meta/recipes-multimedia/libogg (pattern for am335x-pru-support) and meta/recipes-multimedia/flac (pattern for pru-examples). The libogg/flac combo works correctly, mine does not :-( Any pointers on what I might be doing wrong? I'm so close to getting this stuff going, it's just the packaging that's going to claim the last hairs from my head... Thanks n.b. I'm happy to share any of the recipes, I just left them out for brevity. -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------ -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
