Eric, First, I apologize for not providing more information about this test failure report.
I am installing m4 in order to build and test the GCC 9.2.0 release on a variety of Cray and HPE/SGI platforms available in the DoD HPCMP (High Performance Computing Modernization Program) for the Army Corps of Engineers. Here are some platform details: voodoo03> uname -a Linux voodoo03 3.10.0-862.3.2.el7.x86_64 #1 SMP Tue May 15 18:22:15 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux voodoo03> uname -srv Linux 3.10.0-862.3.2.el7.x86_64 #1 SMP Tue May 15 18:22:15 EDT 2018 The compiler is: voodoo03> gcc --version gcc (GCC) 6.3.0 ************************************ File: m4-1.4.18/tests/test-symlink.log ************************************ voodoo03> more m4-1.4.18/tests/test-symlink.log test-symlink.h:70: assertion 'errno == EEXIST || errno == EINVAL' failed FAIL test-symlink (exit status: 134) Please let me know if I need to provide additional information. Thank you very much for your response.

That particular test comes from gnulib; it may be that gnulib has fixed the problem in the test to work around your platform (in which case, we just need a newer m4 release picking up newer gnulib) - but it's hard to tell when you don't provide enough details. > > Is this failure serious? M4 doesn't create symlinks itself, so no, this failure is more an issue with your platform being slightly different than what gnulib assumes (whether that was the fault of your platform or of gnulib), and you can still use your just-built m4 without worry. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org
