Subject: [PATCH] test/test_external_mem: fix loop initialization
Date: Tue, 23 Oct 2018 07:35:50 +0000	[thread overview]
Message-ID: <20181023073535.16441-1-alialnu@mellanox.com> (raw)

Loop initial declarations are only allowed in C99 mode,
which causes a compilation failure on non C99 compliant systems:

test/test/test_external_mem.c: In function ‘test_external_mem’:
test/test/test_external_mem.c:375:2: error: ‘for’
loop initial declarations are only allowed in C99 mode
  for (int i = 0; i < n_pages; i++) {
  ^

Reproduces on RHEL 7.4 with GCC 4.8.5 20150623 (Red Hat 4.8.5-16).

Fixes: b270daa43b3d ("test: support external memory")
