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.
So this means that libraries are not getting linked by just doing the above
changes. What else I need to change?
I think this problem is specific to autotools based projects as when I
include the libraries during the gcc command they are easily included.
do_compile() {
${CC} check.c -o check -lusdpaa_of
}
link to area.bb

I think you need to specify them in Makefile.am using LDADD since it is using auto tools. Please take a look at Automake documentation
http://www.gnu.org/software/automake/manual/html_node/Linking.html <http://www.gnu.org/software/automake/manual/html_node/Linking.html>
might be helpful.

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. :/

Hello,

manuals.
${CC} is a c compiler. For c++ is it ${CXX} or something else.
Thanks.

Yes, you can always do bitbake -e <somepackage> | grep -e “^CXX=“
and figure out various variables that you want to evaluate
