I'm trying to install gettext 0.19.8.1 with Intel 17.0.2 on CentOS 6.8 but
FAIL: test-verify
=================
icc: error #10236: File not found: 'test-verify.o'
FAIL test-verify (exit status: 1)
It looks like the test suite successfully passes when run in serial though.
Thanks for the report. This patch should fix it.


2017-04-20 Bruno Haible <***@clisp.org>

verify tests: Fix spurious failure with parallel make.
* gnulib-tool (func_emit_tests_Makefile_am): Emit initialization of
EXTRA_PROGRAMS.
* tests/test-verify.sh: Build test-verify-try.o, not test-verify.o.
* tests/test-verify-try.c: New file.
* modules/verify-tests (Files): Add it.
(EXTRA_PROGRAMS): Add test-verify-try.
(MOSTLYCLEANFILES): Update accordingly.
