Cuando estoy compilando openvswitch-1.5.0, he encontrado el siguiente error de compilación:
gcc -Wstrict-prototypes -Wall -Wno-sign-compare -Wpointer-arith

Si trato de ver los símbolos de libpthread
, se ve bien.
$ readelf -s /lib/x86_64-linux-gnu/libpthread.so.0 | grep pthread_create
199: 0000000000008220 2814 FUNC GLOBAL DEFAULT 13 pthread_create@@GLIBC_2.2.5

¿Podría dar alguna pista o sugerencia?
