代码如下：

const char* enclave_path = argv[1]; const char* tmp_dir = argv[2]; r = oe_create_test_hostfs_enclave( enclave_path, type, flags, NULL, 0, &enclave); OE_TEST(r == OE_OK); #if defined(_WIN32) tmp_dir = oe_win_path_to_posix(tmp_dir); #endif r = test_hostfs(enclave, tmp_dir); OE_TEST(r == OE_OK); r = oe_terminate_enclave(enclave); OE_TEST(r == OE_OK); printf("=== passed all tests (test_hostfs)\n"); #if defined(_WIN32) free(tmp_dir); #endif |
错误如下：
