Fix gdb 8.1 Solaris compilation
I just tried to compile gdb trunk on Solaris 11.4 (formerly 12), and failed for a couple of reasons: * In file included from /usr/include/python2.7/Python.h:128:0, from /vol/src/gnu/gdb/gdb/dist/gdb/python/python-internal.h:94, from /vol/src/gnu/gdb/gdb/dist/gdb/python/py-instruction.h:23, from /vol/src/gnu/gdb/gdb/dist/gdb/python/py-instruction.c:21: /usr/include/python2.7/ceval.h:67:0: error: ignoring #pragma no_inline [-Werror=unknown-pragmas] #pragma no_inline(PyEval_EvalFrameEx) ^ New in Solaris 11.4: <python2.7/ceval.h> uses a Studio-only #pragma. I've disabled the warning in warnings.m4. * /vol/src/gnu/gdb/gdb/dist/gdb/ser-pipe.c: In function ‘int pipe_open(serial*, const char*)’: /vol/src/gnu/gdb/gdb/dist/gdb/ser-pipe.c:77:9: error: ‘pid_t vfork()’ is deprecated (declared at /usr/include/unistd.h:659) [-Werror=deprecated-declarations] pid = vfork (); ^ /vol/src/gnu/gdb/gdb/dist/gdb/ser-pipe.c:77:16: error: ‘pid_t vfork()’ is deprecated (declared at /usr/include/unistd.h:659) [-Werror=deprecated-declarations] pid = vfork (); ^ Since Solaris 11, vfork () is marked deprecated in <unistd.h>. cf. vfork(2): The vfork() and vforkx() functions are deprecated. Their sole legiti- mate use as a prelude to an immediate call to a function from the exec family can be achieved safely by posix_spawn(3C) or posix_spawnp(3C). Again, I've disabled the warning. * /vol/src/gnu/gdb/gdb/dist/gdb/cli/cli-cmds.c: In function ‘void shell_escape(const char*, int)’: /vol/src/gnu/gdb/gdb/dist/gdb/cli/cli-cmds.c:750:14: error: ‘pid_t vfork()’ is deprecated (declared at /usr/include/unistd.h:659) [-Werror=deprecated-declarations] if ((pid = vfork ()) == 0) ^ /vol/src/gnu/gdb/gdb/dist/gdb/cli/cli-cmds.c:750:21: error: ‘pid_t vfork()’ is deprecated (declared at /usr/include/unistd.h:659) [-Werror=deprecated-declarations] if ((pid = vfork ()) == 0) ^ Same problem. * /vol/src/gnu/gdb/gdb/dist/gdb/procfs.c: In function ‘void procfs_init_inferior(target_ops*, int)’: /vol/src/gnu/gdb/gdb/dist/gdb/procfs.c:4380:30: error: ‘START_INFERIOR_TRAPS_EXPECTED’ was not declared in this scope gdb_startup_inferior (pid, START_INFERIOR_TRAPS_EXPECTED); ^ defined in nat/fork-inferior.h, need to include that header /vol/src/gnu/gdb/gdb/dist/gdb/procfs.c: In function ‘void procfs_create_inferior(target_ops*, const char*, const string&, char**, int)’: /vol/src/gnu/gdb/gdb/dist/gdb/procfs.c:4605:38: error: ‘fork_inferior’ was not declared in this scope NULL, NULL, shell_file, NULL); ^ likewise /vol/src/gnu/gdb/gdb/dist/gdb/procfs.c: In function ‘void procfs_info_proc(target_ops*, const char*, info_proc_what)’: /vol/src/gnu/gdb/gdb/dist/gdb/procfs.c:5124:20: error: ‘argv’ was not declared in this scope for (char *arg : argv) ^ Typo, should be built_argv instead! * Undefined first referenced symbol in file fork_inferior(char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, char**, void (*)(), void (*)(int), void (*)(), char const*, void (*)(char const*, char* const*, char* const*)) procfs.o startup_inferior(int, int, target_waitstatus*, ptid_t*) fork-child.o ld: fatal: symbol referencing errors collect2: error: ld returned 1 exit status make[2]: *** [Makefile:2249: gdb] Error 1 Need to add fork-inferior.o to NATDEPFILES. With the changes below, I can build gdb on sparcv9-sun-solaris2.11 and amd64-pc-solaris2.11 and a simple smoke test (gdb/gdb gdb/gdb) works.
