When there isn't a version-script for a shared library (like for unstable libs), we create one based on the current Xen version. But that version-script became out-of-date as soon as Xen's version changes and make as no way to regenerate the version-script on rebuild. In order to allow regenerating the script, we'll have a different filename. In order to check if the content is up-to-date, we'll always generated it and compare. But we also need to know if there's already an existing version script or if we need to generate one, for that we introduce $(version-script) to be used to point to the path of the existing script. (Guessing if a version script exist for a stable library with for example $(wildcard) won't work as a file will exist when building the library without this patch.) We don't need the version-script unless we are making the shared library so it is removed from the "all" target. Signed-off-by: Anthony PERARD <anthony.perard@citrix.com> --- Alternatively, we could remove the need for to generate a version-script, but that would mean the exported symbols won't have a version anymore (like before, a few versions of Xen ago). Or, we could use --default-symver, but the symboled would be versionned with the soname (e.g. "libxenctrl.so.4.16.0") instead of "VERS_4.16.0". --- Notes: v4: - new patch tools/libs/call/Makefile | 1 + tools/libs/ctrl/Makefile | 3 --- tools/libs/devicemodel/Makefile | 1 + tools/libs/evtchn/Makefile | 1 + tools/libs/foreignmemory/Makefile | 1 + tools/libs/gnttab/Makefile | 1 + tools/libs/guest/Makefile | 3 --- tools/libs/hypfs/Makefile | 1 + tools/libs/light/Makefile | 1 - tools/libs/stat/Makefile | 2 +- tools/libs/store/Makefile | 1 + tools/libs/toolcore/Makefile | 1 + tools/libs/toollog/Makefile | 1 + tools/libs/util/Makefile | 3 --- tools/libs/vchan/Makefile | 3 --- tools/libs/libs.mk | 19 +++++++++++++------ .gitignore | 6 ------ 17 files changed, 23 insertions(+), 26 deletions(-)
