Original bug ID: 6617
Reporter: @whitequark
Assigned to: @gasche
Status: closed (set by @xavierleroy on 2016-12-07T10:47:27Z)
Resolution: fixed
Priority: normal
Severity: minor
Version: 4.02.1
Fixed in version: 4.03.0+dev / +beta1
Category: ~DO NOT USE (was: OCaml general)
Has duplicate: #6830
Related to: #5886

Bug description

In asmrun/signals_osdep.h we have this code:

#if defined(ANDROID)
// The Android NDK does not have sys/ucontext.h yet.
typedef struct ucontext {
uint32_t uc_flags;
struct ucontext *uc_link;
stack_t uc_stack;
struct sigcontext uc_mcontext;
// Other fields omitted...
} ucontext_t;
#else
#include <sys/ucontext.h>
#endif

There probably should be an s.h HAVE_ macro for this, as since r10c NDK includes ucontext_t, which is included from signal.h, and it clashes with this definition.

The fastest way for this to be fixed would probably be that you write a patch yourself. I don't know if other frequent contributors compile OCaml on Android -- the code you want to improve was contributed by Jérôme Vouillon in #5886.

The problem is that I don't do native builds on Android (only cross builds) and thus cannot verify the changes to ./configure script.

I'm not sure anyone has ever done an Android native build...

A simple option is to just remove this Android specific code. I don't think we need to support older versions of the Android NDK.

Otherwise, one could refine the conditional:

#if defined(__ANDROID__) && !defined(_SYS_UCONTEXT_H_)

I'm in favor of removing the conditional altogether. 10c supports all Android versions anyway. Could someone commit this?
