From 887c667089e5417fdc7c5bbb364b027e86a7c113 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sun, 24 Jun 2018 23:33:55 +0200 Subject: [PATCH] nat/fork-inferior: include linux-ptrace.h To decide whether fork() or vfork() should be used, fork-inferior.c uses the following test: #if !(defined(__UCLIBC__) && defined(HAS_NOMMU)) However, HAS_NOMMU is never defined, because it gets defined in linux-ptrace.h, which is not included by fork-inferior.c. Due to this, gdbserver fails to build on noMMU architectures. This commit fixes that by simply including linux-ptrace.h. This bug was introduced by commit 2090129c36c7e582943b7d300968d19b46160d84 ("Share fork_inferior et al with gdbserver"). Indeed, the same fork()/vfork() selection was done, but in another file where linux-ptrace.h was included. Fixes the following build issue: ../nat/fork-inferior.c: In function 'pid_t fork_inferior(const char*, const string&, char**, void (*)(), void (*)(int), void (*)(), const char*, void (*)(const char*, char* const*, char* const*))': ../nat/fork-inferior.c:376:11: error: 'fork' was not declared in this scope pid = fork (); ^~~~ ../nat/fork-inferior.c:376:11: note: suggested alternative: 'vfork' pid = fork (); ^~~~ vfork Signed-off-by: Thomas Petazzoni --- gdb/nat/fork-inferior.c | 1 + 1 file changed, 1 insertion(+) diff --git a/gdb/nat/fork-inferior.c b/gdb/nat/fork-inferior.c index 8b59387fa5..05167628a6 100644 --- a/gdb/nat/fork-inferior.c +++ b/gdb/nat/fork-inferior.c @@ -26,6 +26,7 @@ #include "common-gdbthread.h" #include "signals-state-save-restore.h" #include "gdb_tilde_expand.h" +#include "linux-ptrace.h" #include extern char **environ; -- 2.14.4
