adding pjsip to my openmoko overlay - part 2

Posted on February 28, 2008
Filed Under openmoko |

since my last post i’ve made some progress with my bitbake recipe to build the pjsip project for openmoko.

the first problem i ran into with the install was bitbake complaining that files from a .svn subdirectory from the source tree couldn’t be installed because of a permission problem. those files shouldn’t be installed anyway but were as a side effect of pjsip’s install Makefile rule, which does a recursive copy of the include directories within each subdirectory to /usr/local/include. this fixes it:

# removes all of the .svn files to avoid problems
# during the install
do_remove_svn_files () {
   # "|| true" is to avoid problems with recursing into directories
   # that are removed
   find ${S} -type d -name '.svn' -exec rm -rf {} \; > /dev/null \
      2>&1 || true
}
addtask remove_svn_files after do_unpack before do_patch

pjsip’s makefile is hardcoded to install the libraries and header files into the /usr/local prefix. the default bitbake recipes don’t look for installed files in these directories and complained that the files were installed but not listed in any package. so, copying what i saw in the ffmpeg recipe, i tried this:

FILES_pjsip-dev = “/usr/local/lib/lib*.a \
/usr/local/include/*\
/usr/local/lib/pkgconfig/libpj.pc”

this appears to have no effect. after some trial and error and finally discovering the “-e” option to bitbake, i saw from this command - bitbake -e pjsip | less - that the FILES variable is already assigned by one of the bitbake classes. i thought my assignment would override it but i guess not. instead, something like this is necessary:

FILES_pjsip-dev += "/usr/local/lib/lib*.a \
/usr/local/include/*\
/usr/local/lib/pkgconfig/libpj.pc"

or the more conventional:

FILES_${PN}-dev += "/usr/local/lib/lib*.a \
/usr/local/include/*\
/usr/local/lib/pkgconfig/libpj.pc"

this works perfectly and produces an ipkg file in build/tmp/deploy/glibc/ipk/armv4t.

pjsip’s install Makefile rule doesn’t install any of the command line utilities or the python bindings. i’ll take a stab at those next.

    excellent. is this in openembedded? i haven’t had much time to tinker with openmoko lately but plan to spend some time this week.
