The new meson-test rule in t/Makefile causes a syntax error when the default shell does not support non-standard process substitution: make[1]: Entering directory '/src/git/t' rm -f -r 'test-results' /bin/sh: 10: Syntax error: "(" unexpected make[1]: *** [Makefile:119: check-meson] Error 2 Due to this line: diff -u <(echo "$$meson_tests") <(echo "$$actual_tests"); This can of course be worked around with 'make test SHELL=/bin/bash', but is that expected? Kind regards, Andy
