This commit adds a patch to fix a build issue encountered on noMMU architectures when building gdbserver, due to the use of fork() instead of vfork().

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
