I have a question about the ADT and how it selects host SDK components. If I type:
% bitbake meta-toolchain-sdk I wind up getting hundreds of target libs when I extract the generated tarball: % pwd /opt/poky/1.2.1/sysroots % ls armv5te-poky-linux-gnueabi/usr/lib | wc -l 696 but a relatively small number of host libs: % ls i686-pokysdk-linux/usr/lib | wc -l 53 Is this normal? Taking libxml2 as an example: % ls -1 armv5te-poky-linux-gnueabi/usr/lib/libxml* armv5te-poky-linux-gnueabi/usr/lib/libxml2.la armv5te-poky-linux-gnueabi/usr/lib/libxml2.so armv5te-poky-linux-gnueabi/usr/lib/libxml2.so.2 armv5te-poky-linux-gnueabi/usr/lib/libxml2.so.2.7.8 % ls -1 i686-pokysdk-linux/usr/lib/libxml* zsh: no matches found: i686-pokysdk-linux/usr/lib/libxml* It seems desirable to have libxml2 be part of the SDK I give to my development team. We have a lot of test applications that can be run on the host, and I don't like the thought of somebody wasting time chasing a bug that turns out to be due to the fact that he is linking against a different (system-installed) version of libxml2 rather than the target version. Skimming the ADT manual, this section seems to hint at a solution: - http://www.yoctoproject.org/docs/current/adt-manual/adt-manual.html#adt-package But I can't quite follow all the steps. :-% It says (using libglade as an example): First, you should generate the ipk file for the libglade package and add it into a working opkg repository. Use these commands: $ bitbake libglade $ bitbake package-index Being totally new to opkg, this lost me. What does the 'package-index' target actually do? Does bitbake "add it [libglade] into a working opkg repository" for me, or am I supposed to take the output of the command and do something with it? I had a look in these two locations for 'package-index' and came up empty: - http://www.yoctoproject.org/docs/current/dev-manual/dev-manual.html - http://www.yoctoproject.org/docs/current/poky-ref-manual/poky-ref-manual.html What's the best place to look for these kinds of references when I get stuck on something? The ADT docs go on to say: Next, source the environment setup script found in the Yocto Project files. Follow that by setting up the installation destination to point to your sysroot as <sysroot_dir>. Finally, have an OPKG configuration file <conf_file> that corresponds to the opkg repository you have just created. $ opkg-cl –f <conf_file> -o <sysroot_dir> update $ opkg-cl –f <cconf_file> -o <sysroot_dir> \ --force-overwrite install libglade $ opkg-cl –f <cconf_file> -o <sysroot_dir> \ --force-overwrite install libglade-dbg $ opkg-cl –f <conf_file> -o <sysroot_dir> \ --force-overwrite install libglade-dev <sysroot_dir> I understand, but what is <conf_file>? Did bitbake generate this for me? Am I supposed to create one by hand? Where? These instructions are a little hard to follow due to the use of placeholders rather than concrete arguments. I think a complete, explicit example would help a lot here. Also, it seems likely that the above commands would only install a libglade compiled for the target? How would I generate a libglade for the host? Another question is: is there a way to tune the ADT tarball to be a better fit for my needs so that I don't need to add so many packages by hand after-the-fact? Any advice much appreciated, thanks! _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
