Hi, I've a weird situation: If I build my code using rte.app.mk, then calling rte_eal_init and rte_eth_dev_count returns the proper amount of NICs.
The very same code built with rte.lib.mk into a *.a library does not recognize any NIC (If I include the lib in another test application that only invoke one function that trigger rte_eal_init and rte_eth_dev_count). The output of running rte_eal_init with rte.app.mk on my machine is: . EAL: Detected 8 lcore(s) EAL: Multi-process socket /var/run/.rte_unix EAL: Probing VFIO support... EAL: PCI device 0000:06:00.0 on NUMA socket -1 EAL: Invalid NUMA socket, default to 0 EAL: probe driver: 15b3:1015 net_mlx5 PMD: net_mlx5: PCI information matches, using device "mlx5_0" (SR-IOV: false) PMD: net_mlx5: 1 port(s) detected PMD: net_mlx5: MPS is enabled PMD: net_mlx5: Reserved UAR address space: 0x7f0680000000 PMD: net_mlx5: port 1 MAC address is 7c:fe:90:5e:79:fa EAL: PCI device 0000:06:00.1 on NUMA socket -1 EAL: Invalid NUMA socket, default to 0 EAL: probe driver: 15b3:1015 net_mlx5 PMD: net_mlx5: PCI information matches, using device "mlx5_1" (SR-IOV: false) PMD: net_mlx5: 1 port(s) detected PMD: net_mlx5: MPS is enabled PMD: net_mlx5: port 1 MAC address is 7c:fe:90:5e:79:fb . While the same invocation with the code built using rte.lib.mk generate this output: . EAL: Detected 8 lcore(s) EAL: Multi-process socket /var/run/.rte_unix EAL: Probing VFIO support... . That's all -no more prints-, it seems that nothing else is done by the eal init function. What could be the problem here? As a background note: I'm trying to move my existing DPDK code into a lib, and this is already failing at the first step (eal init). Thanks -- BR, Filip +48 666 369 823
