Jiri Daněk updated DISPATCH-1942:
---------------------------------
Flags: (was: Patch)
> Use modern idiomatic cmake 3.x
> ------------------------------
>
> Key: DISPATCH-1942
> URL: https://issues.apache.org/jira/browse/DISPATCH-1942
> Project: Qpid Dispatch
> Issue Type: Improvement
> Affects Versions: 1.15.0
> Reporter: Jiri Daněk
> Assignee: Jiri Daněk
> Priority: Minor
>
> There has been a [CMake modernization
> PR|https://github.com/apache/qpid-dispatch/pull/288] and an issue
> DISPATCH-1268. Many CMake modernizations could not be applied due to RHEL 6
> support. Both RHEL 6 and 7 bundle cmake 2.8.12.2. Ubunu and Fedora do not
> suffer from ancient CMake.
> Can we raise the minimum required CMake version without impacting RHEL 7/8?
> * There is cmake 3.14.6 and cmake 3.17.5 [available in
> EPEL|https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/c/] for aarch64
> and x86_64, respectively. The full package name (for x86_64) is
> cmake3-3.17.5-1.el7.x86_64.rpm.
> * There is cmake 3.6.2 for RHEL 7 available as part of the
> llvm-toolset-9-rhel7 repository. The full package name is
> llvm-toolset-9.0-cmake-3.6.2-12.el7.x86_64.rpm. There is also
> llvm-toolset-10, but it has the same CMake version in it.
> [Docs|https://access.redhat.com/documentation/en-us/red_hat_developer_tools/1/html-single/using_llvm_10.0.1_toolset/index].
> On the RHEL 8 front, RHEL 8.3 brings cmake-3.11.4-3.el8.x86_64.rpm and it
> does not have any CMake in its EPEL. Upcoming [RHEL 8.4 is promised to bring
> CMake 3.18|https://bugzilla.redhat.com/show_bug.cgi?id=1756974].
> Given the info I collected above, it seems to me that Dispatch can easily go
> to CMake 3.11 in short time, and will be able to further leap to CMake 3.12
> (the one that [improved locating
> Python|https://cmake.org/cmake/help/v3.12/release/3.12.html#modules]) when
> RHEL 8.4 is out. Depending on the situation on other platforms, even newer
> version than 3.12 might be possible then.
