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. > > do_compile() { > ${CC} check.c -o check -lusdpaa_of > } > link to area.bb <http://area.bb/> > http://pastebin.com/Bef2C7nX <http://pastebin.com/Bef2C7nX>-- > _______________________________________________ > yocto mailing list > yocto@yoctoproject.org > https://lists.yoctoproject.org/listinfo/yocto
