${CC} is a c compiler. For c++ is it ${CXX} or something else.
Yes, you can always do bitbake -e somepackage | grep -e “^CXX=“
and figure out various variables that you want to evaluate
Thanks.

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. :/

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. It shows
undefined reference to error.
So this means that libraries are not getting linked by just doing the above
changes. What else I need to change?
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 think this problem is specific to autotools based projects as when I
include the libraries during the gcc command they are easily included.

Subject: Re: [meta-freescale] Including Static Libraries from sysroot in an
autotools based package
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. It shows
undefined reference to error.
So this means that libraries are not getting linked by just doing the above
changes. What else I need to change?
