I managed to reproduce this, but have no real solution just yet… The error is quite unhelpful:

It looks like it is in "json" format. Try that instead. Try '/root/capnproto-0.7.0/.libs/capnp convert --help' for more information. It's complaining about https://github.com/capnproto/capnproto/blob/master/c%2B%2B/src/capnp/testdata/annotated.json, which is obviously valid json, and the "reverse" test works fine: ./capnp convert binary:json src/capnp/compiler/../compat/json-test.capnp TestJsonAnnotations -Isrc/capnp/compiler/../.. < ./src/capnp/testdata /annotated-json.binary -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to capnproto in Ubuntu. https://bugs.launchpad.net/bugs/1870055 Title: capnproto ftbfs in focal on s390x Status in capnproto package in Ubuntu: Confirmed Bug description: second focal test rebuild https://launchpadlibrarian.net/471777379/buildlog_ubuntu-focal-s390x.capnproto_0.7.0-5build1_BUILDING.txt.gz make check-TESTS make[4]: Entering directory '/<<PKGBUILDDIR>>' make[5]: Entering directory '/<<PKGBUILDDIR>>' FAIL: src/capnp/compiler/capnp-test.sh PASS: capnp-evolution-test PASS: capnp-test ======================================== Capn Proto 0.7.0: ./test-suite.log ======================================== # TOTAL: 3 # PASS: 2 # SKIP: 0 # XFAIL: 0 # FAIL: 1 # XPASS: 0 # ERROR: 0 .. contents:: :depth: 2 FAIL: src/capnp/compiler/capnp-test.sh ====================================== /<<PKGBUILDDIR>>/.libs/capnp convert: The input is not in "json" format.
