[dpdk-dev] [PATCH v2] windows: minor build fixes

[Nick Connolly]

Meson versions >= 0.54.0 include support for handling /implib
with msvc link. Specifying it explicitly causes failures when
linking against the dll. Tested using Link 14.27.29112.0 and
Clang 11.0.0.

There were a number of changes to the way that import libraries
are handled between 0.47.1 and 0.54.0. Only make the change
for >= 0.54.0, leaving the behaviour unchanged for earlier
versions.

Missing / incorrect '--in-reply-to'. Please ignore - still learning the

How can we verify this behavior change in 0.54 is intentional? 
I cannot find it in the versions' release notes:

[dpdk-dev] [PATCH] Windows: minor build fixes

[Nick Connolly]

Don't run symlink-drivers-solibs.sh as part of 'install' because
Windows doesn't support shell scripts, causing the install to
fail.

Meson versions >= 0.54.0 include support for handling /implib
with msvc link. Specifying it explicitly causes failures when
linking against the dll. Tested using Link 14.27.29112.0 and
Clang 11.0.0.

[dpdk-dev] [PATCH v2] windows: minor build fixes

[Nick Connolly]

Meson versions >= 0.54.0 include support for handling /implib
with msvc link. Specifying it explicitly causes failures when
linking against the dll. Tested using Link 14.27.29112.0 and
Clang 11.0.0.

There were a number of changes to the way that import libraries
are handled between 0.47.1 and 0.54.0. Only make the change
for >= 0.54.0, leaving the behaviour unchanged for earlier
versions.
