Unable to install a shared library in yocto - linux

Question

I wrote a recipe to build a shared library. Here is the recipe
SUMMARY = "test library"
SRC_URI = " file://file1.c \
file://file2.c \
file://internal.h"
LICENSE = "CLOSED"
FILES_${PN} = "libtest.so"
do_compile() {
${CC} -fPIC -c ${WORKDIR}/file1.c -o ${WORKDIR}/file1.o
${CC} -fPIC -c ${WORKDIR}/file2.c -o ${WORKDIR}/file2.o
${CC} -shared -o ${WORKDIR}/libesys.so ${WORKDIR}/file1.o ${WORKDIR}/file2.o
}
do_install() {
install -d ${D}${libdir}
install -m 0644 ${WORKDIR}/libtest.so ${D}${libdir}/
}
It fails with the following errors:
ERROR: test-0.1-r0 do_package_qa: QA Issue: -dev package contains non-symlink .so: test-dev path '/work/corei7-64-poky-linux/test/0.1-r0/packages-split/test-dev/usr/lib64/libtest.so' [dev-elf]

ERROR: Task (/home/jamal/repotest1/sources/meta-test/recipes-support/test/test_0.1.bb:do_package_qa) failed with exit code '1'
Can you please help me in to find out the issue.. Appreciate your efforts.

Answer 1

Default packaging rules assumes that libraries are versioned, and your libraries are not.
Either install versioned libraries, or if you really don't want to https://wiki.yoctoproject.org/wiki/TipsAndTricks/Packaging_Prebuilt_Libraries#Non-versioned_Libraries shows you how to manipulate the rules.
