Please don't link vpp_api_test against libvnet.so. Your test plugin - and vpp_api_test by implication - have no use for data plane node implementations, and so on, and so forth.
Instead, create a client library which contains ip_types_api.c and similar xxx_api.c files, and link the test plugin against it. That's 100% CMakeLists.txt hacking, won't break anything, etc. Copying Ole for a second opinion. D.

Dear VPP-dev, I bumped into an issue as below since I called ip_address_encode() function in src/plugins/lb/lb_test.c ./vpp_api_test: symbol lookup error: /root/vpp/build-root/build-vpp-native/vpp/lib/vpp_api_test_plugins/lb_test_plugin.so: undefined symbol: ip_address_encode But actually ip_address_encode() was compiled in libvnet.so, vpp/build-root/install-vpp-native/vpp/lib# nm libvnet.so |grep ip_address_encode 0000000000623d30 T ip_address_encode So I do below changes in order to let VAT can link with libvnet.so, but it did not take effect. diff --git a/src/vat/CMakeLists.txt b/src/vat/CMakeLists.txt index d512d9c17..81b99bd3d 100644 --- a/src/vat/CMakeLists.txt +++ b/src/vat/CMakeLists.txt @@ -16,7 +16,7 @@ ############################################################################## add_vpp_library(vatplugin SOURCES plugin_api.c - LINK_LIBRARIES vppinfra + LINK_LIBRARIES vnet vppinfra ) ############################################################################## @@ -33,6 +33,7 @@ add_vpp_executable(vpp_api_test ENABLE_EXPORTS DEPENDS api_headers LINK_LIBRARIES + vnet vlibmemoryclient svm vatplugin Could you guys help me about this issue ?
