Is there some way we could get bitbake to collapse this and remove the duplicates? I found that this happens in meta-fsl-arm:recipes-graphics/imx-gpu-viv/imx-gpu-viv.inc which contains these lines: PROVIDES += "virtual/wayland-egl virtual/libgal-x11 virtual/egl virtual/libopenvg virtual/libg2d" PROVIDES_append_mx6q = " virtual/libgl virtual/libgles1 virtual/libgles2" PROVIDES_append_mx6dl = " virtual/libgl virtual/libgles1 virtual/libgles2" PROVIDES_append_mx6sx = " virtual/libgl virtual/libgles1 virtual/libgles2" Some i.MX6 targets, nitrogen6x in particular, has overrides for both mx6q and mx6dl, hence the duplication. Note: I removed the extra override (for testing) and found that now the packages built by target A can be shared via sstate with target B (at least the few I tested)I agree this would be nice, but for this to work we'd probably need to introduce a typing system within bitbake so that it can understand that this variable is a space-separated list. That is something we will probably do at some point for a variety of reasons, but I don't know that it's something we will get to soon.
Is there some way to solve this in the recipe itself? I can see that it needs to make sure that those values are provided for each of the [sub]class of processor, but is there a way to write it so that they are only added once? Perhaps a little bit of Python magic? -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------ -- _______________________________________________ yocto mailing list [email protected] https://lists.yoctoproject.org/listinfo/yocto
