Build wangle encountered error: error: use of undeclared identifier 'malloc_usable_size' #65

When I tried to build wangle, it reported: In file included from /project/opensource/source/wangle/wangle/../wangle/concurrent/ThreadPoolExecutor.h:19: In file included from /project/opensource/source/wangle/wangle/../wangle/deprecated/rx/Observable.h:20: /usr/local/include/folly/small_vector.h:619:14: error: use of undeclared identifier 'malloc_usable_size' return malloc_usablesize(u.pdata.heap_) / sizeof(value_type);

I've built "folly" successfully, did anyone encounter the same issue? Thanks!

Yes I am getting the same issue. I was also able to compile folly without any issues. I am using MAC OS X 10.11.6 and gcc 6. This is happening after pulling the latest master branch after about few months on both folly and wangle.

It turns out it has something to do with jemalloc. when I checked the configure output of compiling folly it had checked and said malloc_usable_size yes but for malloc.h check it had said false. Then when I uninstalled jemalloc from my system , recompiled folly, it said malloc_usable_size as false and after this I could build wangle fine.

Thanks @mohnishkodnani , after I removed jemalloc, it works now.

It still not work after i removed jemalloc from my system(OSX 10.12).

I am having problem with this too. Installed folly with homebrew, got back luck with small_vector.h.

I got the same problem. No difference with removing jemalloc, installing folly by homebrew / compiling source in macOS 10.12.1.

I am getting the same issue. My machine is OS X 10.12. Any update?

folly/portability/Malloc.cpp provides a defintion for malloc_usable_size for apple platforms. Can you check why that code is not being executed on your platform (e.g., put a #error "check") inside the APPLE guard.

howardzhang commented 7 years ago

@anirudhvr I was able to resolve this issue using @mohnishkodnani method.
