未能使用meson依赖项()指令静态地链接到dpdk

Question

我试图使用meson来构建dpdk的helloworld示例，作为一个独立的应用程序。我希望将应用程序静态地链接到dpdk库中。

我已经下载了DPDK22.07到/home/aizrailev/dpdk，并将其安装到/home/aizrailev/dpdk/install (如果dpdk是在系统范围内安装的，那么一切都很好)。然后我转到/home/aizrailev/dpdk/examples/helloworld，尝试使用下面的meson.build构建应用程序(在此之前，我运行export PKG_CONFIG_PATH=/home/aizrailev/dpdk/install/lib/x86_64-linux-gnu/pkgconfig)：

project('dpdk-app', 'c')                                                                                                                                                                      
                                                                                                                                                                                              
dpdk = dependency('libdpdk', static: true)                                                                                                                                                    
sources = files('main.c')                                                                                                                                                                     
executable('dpdk-app', sources, dependencies: dpdk) 

构建应用程序的步骤：

meson build
cd build/
ninja

发生下列错误：

但是，如果我使用另一个显式调用pkg-config的meson.build来获取标志，那么一切都很好：

project('dpdk-app', 'c')

pkgconfig = find_program('pkg-config')
cflags_cmd = run_command(pkgconfig, '--cflags', 'libdpdk', check: true)
ldflags_cmd = run_command(pkgconfig, '--static', '--libs', 'libdpdk', check: true)

cflags = cflags_cmd.stdout().split()
ldflags = ldflags_cmd.stdout().split()

sources = files('main.c')
executable('dpdk-app', sources, c_args: cflags, link_args: ldflags)

因此，介子使用依赖项的本机方式会导致错误。我是不是遗漏了什么？我不认为像我在第二个meson.build中那样调用pkg-config是实现我想要的效果的好方法，但是我找不到其他的选择。

根据这些评论，这个问题被描述为meson fails to statically build the dpdk application。但是，在本地研究这个问题不会产生错误，下面的介子构建文件如下

project('dpdk-app', 'c')

pkgconfig = find_program('pkg-config')
cflags_cmd = run_command(pkgconfig, '--cflags', 'libdpdk', check: true)
ldflags_cmd = run_command(pkgconfig, '--static', '--libs', 'libdpdk', check: true)

cflags = cflags_cmd.stdout().split()
ldflags = ldflags_cmd.stdout().split()

sources = files('main.c')
executable('dpdk-app', sources, c_args: cflags, link_args: ldflags)

步骤：

将dpdk示例将dpdk示例复制到自定义文件夹中(例如: /tmp/mytest)

• add the meson.build to the folder.

• populate，内容具有共享步骤as

• use meson-ninja以构建应用程序(meson build；ninja -C build)
• application不需要任何errors
• run )，应用程序使用./build/dpdk-app (它工作)

F 226构建

但是我们得到了错误，如果我们使用介子构建

project('test', 'c')

dpdk = dependency('libdpdk', static: true)
sources = files('main.c')
executable('dpdk-app', sources, dependencies: dpdk, )

仔细检查错误日志

/usr/bin/ld: /usr/lib/x86_64-linux-gnu/libpcap.a(bpf_filter.o): in function `bpf_validate':
(.text+0x460): multiple definition of `bpf_validate'; /usr/local/lib/x86_64-linux-gnu/librte_bpf.a(librte_bpf_bpf_validate.c.o):bpf_validate.c:(.text+0x23c0): first defined here

错误来自librte_bpf.a和libpcap.a。

若要解决此问题，请将介子构建更新为

project('test', 'c',)

dpdk = dependency('libdpdk', static: true)
sources = files('main.c')
executable('dpdk-app', sources, dependencies: dpdk, link_args : ['-lsystemd', '-Wl,--allow-multiple-definition',])

如上文所述，如果设置正确，则DPDK或pkg-config没有问题。但是实际的错误来自包含相同函数名和代码的库。
