[yocto] [Yocto-builds] Linking of external libraries in the recipe

Sun Mar 15 22:03:54 PDT 2015

Did this:

DPENDS += "usdpaa"
EXTRA_OECONF_append = "    LDFLAGS = "-L/usr/lib/" \
            LIBS="-lusdpaa_dma -lusdpaa_dma_mem -lusdpaa_of -lusdpaa_fman
-lusdpaa_qbman -lusdpaa_syscfg" \
            CXXFLAGS="-I/usr/include/""

Its still failing.

configure: WARNING: you should use --build, --host, --target
configure: error: invalid variable name: `'
Didn't work even with single inverted comma.
