Hi Guys, I am using DPDK with the yocto build system.
I found some static library is not linked because of the linker's as-needed decision. Some .a file use __attribute__((constructor)) to register their APIs, we only know if we use these APIs at runtime, but linker make the decision early and then discarded them. I tried a lot to link the library I need: 1, use -Wl, --no-as-needed, for example: gcc a.c *-Wl, --no-as-needed* -ldl -ldpdk 2, Put the library explicitly to the linker like this: gcc a.c -Wl, --no-as-needed -ldl -ldpdk *-lrte_mempool* At last, I still didn't find my library in the elf file. Is there anything else I can try to link these library? -- Thanks & Best Regards Liu Hui --
