Building RPM of go software


(Dan) #1

I’ve been cheating on my packages for acme-dns–I’ve just been taking the developer’s pre-compiled binaries and packaging them into RPMs. But that really isn’t the concept of RPMs; they’re intended to be built from source. I haven’t been able to find much in the way of documentation on how to do this with go, and I’m probably in over my head, but that hasn’t stopped me before… @mark_nl has shared some very helpful information that gets me to the point of building the app, but I’m having trouble translating that into building a RPM. Here’s what I’ve got so far:

  • Build the .spec file. Make sure to include BuildRequires: go. Here’s what I have in mine, in what I think is the relevant part:
%prep
%setup -c -q -n "acme-dns-%{pkg_version}"
cp %{SOURCE1} %{_builddir}/acme-dns-%{pkg_version}
mv %{_builddir}/acme-dns-%{pkg_version}/acme-dns-%{pkg_version}/* %{_builddir}/acme-dns-%{pkg_version}/
mv %{_builddir}/acme-dns-%{pkg_version}/vendor/ %{_builddir}/acme-dns-%{pkg_version}/src/
export GOPATH=%{_builddir}/acme-dns-%{pkg_version}/

%build
go build -v -o acme-dns
  • Put the .spec file and the source files into a directory
  • Use mock to build the .srpm: mock -r nethserver-7-x86_64 --buildsrpm --spec <specfile> --sources . --resultdir . This finishes without apparent issue.
  • Then use mock to build the binary RPM: mock -r nethserver-7-x86_64 --rebuild <.src.rpm> --resultdir . This is where I have a problem:
+ go build -v -o acme-dns

This package appears to be trying to pull in other packages from GitHub, and isn’t able to do so, resulting in build failure. If I set up a mock environment and run the go build command inside it, I’m able to build this package without an issue. Where should I be looking to fix this?

OK, solved this problem. Replaced these lines in the .spec file:

export GOPATH=%{_builddir}/acme-dns-%{pkg_version}/
go build -v -o acme-dns

…with this one in %build:

GOPATH=%{_builddir}/acme-dns-%{pkg_version}/ go build -v -o acme-dns

Still TBD whether the resulting RPM works, but it’s definite progress.
