我正在尝试在Windows 7主机上以VirtualBox来宾运行的内核版本4.13.0在Ubuntu 16.04 64bit上构建DPDK 16.11.1和17.02.1：
wwa@ssa:~/dpdk-stable-16.11.1$ uname -a
Linux osboxes 4.13.0-32-generic #35~16.04.1-Ubuntu SMP Thu Jan 25 10:13:43 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
DPDK配置为
x86_64-native-linuxapp-gcc：wwa@ssa:~/dpdk-stable-16.11.1$ make config T=x86_64-native-linuxapp-gcc CC=gcc
Configuration done
在构建DPDK时，出现以下编译错误：
error: implicit declaration of function ‘pci_enable_msix’。这是完整的输出：wwa@ssa:~/dpdk-stable-16.11.1$ make CC=gcc

有谁知道为什么会中断？
我在16.11.1和17.02.1上都有相同的错误
最佳答案
我看到在较新版本的DPDK中已经有一个fix。我想您有几种选择：
在本地DPDK代码上应用the patch
使用较新的DPDK版本
使用低于4.8的Linux内核
编辑：仅对DPDK 16.11应用补丁是不够的。
如果不是更改DPDK版本或迁移到较旧内核的选项，则还可以更改以下代码以类似于dpdk patch的方式调用pci_enable_msix_range而不是pci_enable_msix：
lib/librte_eal/linuxapp/igb_uio/igb_uio.c:
igbuio_pci_probe(struct pci_dev *dev, const struct pci_device_id *id)
{
struct rte_uio_pci_dev *udev;
struct msix_entry msix_entry;
int err;
[...]
switch (igbuio_intr_mode_preferred) {
case RTE_INTR_MODE_MSIX:
/* Only 1 msi-x vector needed */
msix_entry.entry = 0;
if (pci_enable_msix(dev, &msix_entry, 1) == 0) {
dev_dbg(&dev->dev, "using MSI-X");
udev->info.irq = msix_entry.vector;
udev->mode = RTE_INTR_MODE_MSIX;
break;
}
/* fall back to INTX */
[...]
