[ovs-discuss] fail configure --with-dpdk=$DPDK_BUILD CFLAGS="-g -O2 -Wno-cast-align"

[Serguei Bezverkhi (sbezverk)]

Hi Ben,

As you suggested I check config.log and it appears the error is not dpdk related but fusea related.

| /* end confdefs.h.  */
| #include <rte_config.h>
|                              #include <rte_eal.h>
| int
| main ()
| {
| int rte_argc; char ** rte_argv;
|                              rte_eal_init(rte_argc, rte_argv);
|   ;
|   return 0;
| }
configure:18260: gcc -std=gnu99 -o conftest -g -O2 -Wno-cast-align -I/root/virtualization/dpdk/x86_64-native-linuxapp-gcc//include   -L/root/virtualization/dpdk/x86_64-native-linuxapp-gcc//lib conftest.c -lintel_dpdk -ldl -lpthread -lrt -lm  -lfusea >&5
/usr/bin/ld: cannot find -lfusea
collect2: error: ld returned 1 exit status
configure:18260: $? = 1
configure: failed program was:
| /* confdefs.h */

I have fuse and fuse-devel installed.

Anything else I could check?

Thank you

Serguei

I'd start by looking at config.log.  It should show the commands that "configure" used to try to link against DPDK.  Can you figure out why they did not succeed?
