Using %gobuildflags with %meson
I have a package[1] that I'm updating to a new upstream version. Upstream, the project
uses meson to compile the binaries (written in Go), as well as generate and install a
number of data files. I want to use meson to compile and install the project downstream
because I feel meson does a good job managing all the data files and installation
directories.
I am trying to replicate the logic of the %gobuild macro so that I can continue to use
meson *and* use as much of the go-rpm-macros as possible, with as little duplication as
possible. Upstream, I have defined custom_targets[3] for the Go binaries with the
following command array:
[go, 'build', gobuildflags, '-o', '@OUTPUT@',
'-ldflags', goldflags, packagename]
gobuildflags is an array that is constructed[4] from a meson build option[3].
In my spec %build, I attempt to set the gobuildflags meson build option like so:
%meson -Dgobuildflags=%{shescape:%gobuildflags}
When meson parses the incoming gobuildflags value and splits the string into an array, it
separates the value of the -tags flag into two separate single-quoted command line
arguments like this (extracted from the resulting ninja.build):
COMMAND = /usr/bin/go build -buildmode pie -compiler gc
'-tags="rpm_crashtraceback' '$${BUILDTAGS:-}"' ...
Is there some other way I can pass the output of %gobuildflags into meson as a build
option that doesn't split apart the double-quoted values like this?
