Subject: [PATCH] build: Make the build flags match Fedora's %{gobuild}
|
|
|
|
The Go toolchain doesn't play well with passing compiler and linker
|
|
flags via environment variables. The linker flags require a second
|
|
level of quoting, which leaves the build system without a quote level
|
|
to assign the flags to an environment variable like GOFLAGS.
|
|
|
|
This is one reason why Fedora doesn't have a RPM macro with only the
|
|
flags. The %{gobuild} RPM macro includes the entire 'go build ...'
|
|
invocation.
|
|
|
|
The Go toolchain also doesn't like the LDFLAGS environment variable as
|
|
exported by Fedora's %{meson} RPM macro.
|
|
|
|
Note that these flags are meant for every CPU architecture other than
|
|
PPC64, and should be kept updated to match Fedora's Go guidelines. Use
|
|
'rpm --eval "%{gobuild}"' to expand the %{gobuild} macro.
|
|
|
|
For some reason, when built on Koji, the final binary gets created as
|
|
../src/src instead of ../src/toolbox, but it doesn't happen when
|
|
building locally with 'rpmbuild -ba ...'. Hence it's necessary to
|
|
explicitly specify the name of the output binary.
