[dpdk-dev] [PATCH 0/6] build system improvements

[Thomas Monjalon]

While testing compilation of mlx drivers,
I hit some issues and misses.
The result is 6 patches of cleanup, fixes and test improvements.

Thomas Monjalon (6):
  build: remove redundant libs from pkgconfig
  drivers: add some reasons for meson disabling
  net/mlx: fix meson build with custom dependency path
  net/mlx: fix build with make and recent gcc
  devtools: test compiler availability only once
  devtools: load target-specific compilation environment

[dpdk-dev] [PATCH 1/6] build: remove redundant libs from pkgconfig

[Thomas Monjalon]

As explained in drivers/meson.build,
"
  For the find_library() case (but not with dependency()) we also
  need to specify the "-l" flags in pkgconfig_extra_libs variable
  too, so that it can be reflected in the pkgconfig output for
  static builds.
"

The commit e30b4e566f47 ("build: improve dependency handling")
must be followed up with this one in order to remove more
occurences of pkgconfig_extra_libs redundant with use of dependency().

[dpdk-dev] [PATCH 3/6] net/mlx: fix meson build with custom dependency path

[Thomas Monjalon]

If rdma-core is not installed in a standard directory of the system,
it is possible to specify the location of the pkgconfig file via
an environment variable:
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:~/rdma-core/build/lib/pkgconfig

In this case, the dependency may become mandatory to specify
for the configuration tests (checking dependency symbols or fields).

Some spacing is also fixed around.

[dpdk-dev] [PATCH 4/6] net/mlx: fix build with make and recent gcc

[Thomas Monjalon]

With VERBOSE=1, this error was seen in debug mode with gcc 9.1:

In file included from /tmp/dpdk.auto-config-h.sh.c.w0VWMi:1:
In file included from rdma-core/build/include/infiniband/mlx5dv.h:47:

__aligned_u64 driver_data0;
^
1 error generated.

As a result, buildtools/auto-config-h.sh was not generating
a correct autoconf file, so the compilation was generating such error:

fatal error: redefinition of 'mlx5_ib_uapi_flow_action_packet_reformat_type'

It is fixed by disabling -pedantic option when calling auto-config-h.sh
from the makefile-based system.

[dpdk-dev] [PATCH 5/6] devtools: test compiler availability only once

[Thomas Monjalon]

The compilation test is skipped if the compiler is not available.
In the case of gcc/arm, it was tested both in the generic function
"build" and in the cross-compilation section.

By passing the compiler as argument of the generic function,
the test with "command" is done only once.

This small clean-up has the benefit of introducing the compiler
parameter to be used later in another improvement.

[dpdk-dev] [PATCH 6/6] devtools: load target-specific compilation environment

[Thomas Monjalon]

In order to re-use the same test environment as with
test-build.sh, the configuration file is loaded at each build,
after adjusting the variable DPDK_TARGET.

This is especially useful to set the variable PKG_CONFIG_PATH,
or define some meson options (without -D) in DPDK_MESON_OPTIONS.

The DPDK_TARGET values can be
	aarch64-*, powerpc64-*, x86_64-*.
The matching DPDK_TARGET values for test-build.sh are
	arm64-*, ppc_64-*, x86_64-*.
The advised expressions to use in the common configuration file are:
	if echo $DPDK_TARGET | grep -q '^a.*64-' ; then
	elif echo $DPDK_TARGET | grep -q '^p.*pc.*64' ; then
	elif echo $DPDK_TARGET | grep -q '^x86_64' ; then
	fi
