对 DPDK mlx5 中“mlx5dv_create_flow_action_packet_reformat”的未定义引用

undefined reference to `mlx5dv_create_flow_action_packet_reformat' in DPDK mlx5

mlx5dv_create_flow_action_packet_reformat是 <infiniband/mlx5dv.h> 中的一个函数。

错误显示：未定义对“mlx5dv_create_flow_action_packet_reformat”的引用。

为什么我无法链接mlx5dv_create_flow_action_packet_reformat功能。

这是否意味着我需要下载一些依赖包？

请使用 DPDK 版本、Linux 版本和正在使用的发行版进行更新。错误的简单解释，就是在默认路径下找不到mlx5库。我假设您正在本地构建 DPDK（相同的机器构建和运行），然后LD_LIBRARY_PATH指向 的位置。libverb*.so

检查您的屏幕截图，这不是 DPDK 构建问题，而是使用某些 Makefile 进行编译的应用程序。请分享您的以评估问题所在。Makefile

我使用的 DPDK 版本是 18.11。

应用程序 Makefile 标志的问题，因为它仅包含通过 的 DPDK 标头。基于日志 .r2p2-echo-I$(RTE_SDK)/x86_64-native-linuxapp-gcc/includeDPDK is been built Mellanox PMD drivers which have an inherent dependency on libverbs to provide the definition for mlx5_glue_*

以下是解决问题的方法

  1. 如果应用程序不使用 Mellanox PMD，请使用 重建 DPDK （< 19.11 LTS）。然后重新生成应用程序。CONFIG_RTE_LIBRTE_MLX5_PMD=nrte_config
  2. 如果应用程序确实使用 Mellanox PMD，则需要修改 CFLAGS 和 LDFLAGS 以适应 libverb 的路径和定义。
  3. 如果 DPDK 为 19.11 LTS 或更高，则使用 DPDK 可以获取相应的 CFLAGS 和 LDFLAGS。pkg-config

使用 pkg-config 的解决方案：

CFLAGS更新：

CFLAGS += -g -O3 -I$(ROOTDIR)/netstack/inc -I$(R2P2LIB_DIR)/inc $(pkg-config --cflags --static libdpdk) -I$(RAFT_DIR)/include -DNO_BATCH #-DACCELERATED #-DRAFT_STATS

和

用于 LDFLAGS

r2p2-echo: cleanstate r2p2-echo.o $(OBJS_C)
    $(CC) -o $@ r2p2-echo.o $(OBJS_C) $(LDFLAGS) $(pkg-config --static --libs libdpdk)

DPDK 版本低于 19.11 LTS 的解决方案：

  • 执行 。make static -n or make -nexample/l2fwd
  • 这将为用于使用 DPDK 库和依赖项构建应用程序的编译器标志生成日志。
  • 提取 cflags 和 ldflags 的必要字段并更新 makefile。

我现在正在使用 DPDK v20.05。因此，我尝试了 DPDK > 19.11 的解决方案 1。我已经更新了 CFLAGS。但是，它会报告一个错误： 。这可能是由于我用 .那么我应该怎么做才能解决这个问题呢？fatal error: rte_config.h: No such file or directory-I$(RTE_SDK)/x86_64-native-linuxapp-gcc/include$(pkg-config --cflags --static libdpdk)

$(pkg-config --cflags --static libdpdk)将仅返回 CFLAGS fileds，而返回 ldflags 字段。分享项目链接，让我一起来看看。$(pkg-config --libs --static libdpdk)
