examples: build some samples with meson Add support for having selected example apps built as part of a meson, ninja build. By default none are built, and those to be built should be named directly in the -Dexamples='' meson configuration argument. This is useful for developers working on a feature who want to use a suitable example, or examples, to test that feature, as they can compile everything up in one go, and run the example without having to do a ninja install first. This commit adds examples which don't consist of multiple apps in subdirectories to the meson build, so they can be built by default by passing -Dexamples parameter to meson. Not included are the following examples: * ethtool * multi-process * netmap_compat * performance-thread * quota_watermark * server_node_efd * vm_power_manager To test the apps added here, use the following command, merged to one line, to add them to your meson build (command to be run inside the build directory): meson configure -Dexamples=bbdev_app,bond,cmdline,distributor,\ eventdev_pipeline_sw_pmd, exception_path,helloworld,\ ip_fragmentation,ip_pipeline,ip_reassembly, ipsec-secgw,\ ipv4_multicast,kni,l2fwd-cat,l2fwd-crypto,l2fwd-jobstats,\ l2fwd-keepalive,l2fwd,l3fwd-acl,l3fwd-power,l3fwd-vf,l3fwd,\ link_status_interrupt,load_balancer,packet_ordering,ptpclient,\ qos_meter,qos_sched,rxtx_callbacks,skeleton,tep_termination,\ timer,vhost,vhost_scsi,vmdq,vmdq_dcb Signed-off-by: Bruce Richardson <bruce.richardson@intel.com> Reviewed-by: Luca Boccassi <bluca@debian.org>

build: always link whole DPDK static libraries To ensure all constructors are included in static build, we need to pass the --whole-archive flag when linking, which is used with the "link_whole" meson option. Since we use link_whole for all libs, we no longer need to track the lib as part of the static dependency, just the path to the headers for compiling. After this patch is applied, all DPDK .a files are inside --whole-archive/--no-whole-archive flags, but external dependencies and shared libs being linked against remain outside.

build: fix for host clang and cross gcc The following error hits if host cc compiler is clang(default one in most linux distributions) and the cross compiler is gcc. The root cause is: the hybride compilers add the warning options to the meson project as project arguments, which apply for both host compiling and cross compiling. But some options such as '-Wno-format-truncation' are not supported nor recognized by clang, so they have to be removed from the project arguments for the host compiler to run smoothily and added back as cflags for the cross compiler to compile for cross source files. The fix is remove unrecognized warning options from the meson project arguments shared by gcc and clang, as add them specifically for gcc or clang as cflags.

examples: skip build when missing dependencies Trying to disable the vhost library, meson will complain it can't build the vhost* and vdpa examples when passing -Dexamples=all. -Dexamples=all skips examples if the example itself announces it can't be built (for external dependencies, internal dependencies and other reasons). Since examples/meson.build will evaluate the internal dependencies in any case, let's move the check there and resolve the issue for optional internal libraries.

examples: reduce indentation in build files As with the lib and drivers directories, we can use "continue" keyword to reduce the indentation level of the majority of the foreach block. At the same time, we can also replace tab indentation with spaces. Signed-off-by: Bruce Richardson <bruce.richardson@intel.com>

examples: build some samples with meson Add support for having selected example apps built as part of a meson, ninja build. By default none are built, and those to be built should be named directly in the -Dexamples='' meson configuration argument. This is useful for developers working on a feature who want to use a suitable example, or examples, to test that feature, as they can compile everything up in one go, and run the example without having to do a ninja install first. This commit adds examples which don't consist of multiple apps in subdirectories to the meson build, so they can be built by default by passing -Dexamples parameter to meson. Not included are the following examples: * ethtool * multi-process * netmap_compat * performance-thread * quota_watermark * server_node_efd * vm_power_manager To test the apps added here, use the following command, merged to one line, to add them to your meson build (command to be run inside the build directory): meson configure -Dexamples=bbdev_app,bond,cmdline,distributor,\ eventdev_pipeline_sw_pmd, exception_path,helloworld,\ ip_fragmentation,ip_pipeline,ip_reassembly, ipsec-secgw,\ ipv4_multicast,kni,l2fwd-cat,l2fwd-crypto,l2fwd-jobstats,\ l2fwd-keepalive,l2fwd,l3fwd-acl,l3fwd-power,l3fwd-vf,l3fwd,\ link_status_interrupt,load_balancer,packet_ordering,ptpclient,\ qos_meter,qos_sched,rxtx_callbacks,skeleton,tep_termination,\ timer,vhost,vhost_scsi,vmdq,vmdq_dcb Signed-off-by: Bruce Richardson <bruce.richardson@intel.com> Reviewed-by: Luca Boccassi <bluca@debian.org>
