Hi, from my mail to the opensuse-factory list: I have a successfully building ltrace for OpenSUSE:Leap:15.2 (see https://build.opensuse.org/package/show/home:msalle:branches:openSUSE:Leap:15.2/ltrace) all changes relate to the failing 'make check'. It has a new patch testsuite.patch: - it fixes the warnings from make check - it removes one entry which is using long double which isn't supported by ltrace while the test assumed it did (I actually have a quite extensive patch that enables long double, at least for my 64-bit Leap 15.1). Plus some small changes to the spec file: - put make check inside a %check - it enforces using en_US.UTF-8 for running the tests, otherwise wchar.exp fails. Another UTF-8 locale should be fine too, but not setting it breaks the tests.
