I have edited the Makefile.am as well in this way: squid_LDADD += -lusdpaa_of
Then I just retarred squid code and build it again. And The libraries are shown in the compile command as well, when I see the log.do_compile generated during the build. Check Line number 403 in this pastebin link. (ctrl+F 'usdpaa_of' could show where all it occurs). http://pastebin.com/LpaymTQa So how is it possible they are not actually linked. I even checked the OVERRIDE variable in bitbake.conf which is set correctly. I really need to link this library. :/ On Fri, Mar 20, 2015 at 8:43 AM, Khem Raj <raj.k...@gmail.com> wrote: > > On Mar 19, 2015, at 2:07 AM, Priya Agarwal < > priya_agar...@students.iitmandi.ac.in> wrote: > > Hi, > > I need to link some libraries which are in sysroot into my source code. > These are usdpaa libraries. > > I added DEPENDS += "usdpaa" in .bb file. > Apart from that also changed the Makefile.am of my source to include the > following: > area_LDADD = -lusdpaa_of > Then I ran aclocal, autoconf, automake --add-missing and retarred my > package. > > When the package is being built from recipe, do_compile fails.
