Compile error when building for Android on Chromium 40?

[Peter Pettersson]

Hello,

Last time I used dmprof was on some time around Chromium 37-39 and then it worked well. But I just tried to build it with the latest Chromium and now it gives me a compile error that I'm guessing is related to a new NDK version.

I was following the build instructions on http://www.chromium.org/developers/deep-memory-profiler , are they still up to date?

My gyp configuration:

OS=android profiling=1 profiling_full_stack_frames=1 linux_dump_symbols=1 use_allocator="tcmalloc"

Ninja output:

peterp@peterp-ubuntu:/path/to/src$ ninja -C out/Release content_shell_apk

ninja: Entering directory `out/Release'

Thankful for any help.

Hi, Same issue with commit 56fe65679b79312cb84b42d127bb8a84f79167d5 Date:   Thu Dec 18 22:33:46 2014 -0800. 

Do you know any workaround?

Seems some thing wrong when compiling tcmalloc, How about upgrading tcmalloc? So far, tcmalloc(Revision: 144) is too old to enabling dmprof on ARM64 (see Issue 423298).

Hi,

I was working on this issue.

afaik , it's because latest NDK L includes ucontext_t as different struct.

we want to use ucontext_t as Unwind_Context.

however unfortunately it is written by typedef. so we can not avoid or undef the typedef.

so I made a patch with namespace. maybe this would resolve this issue.

it is still checking...
