Building libc++ with tbbmalloc

[Marky__Marky]

Hi,

I came up with project to create a libc++ library using tbbmalloc instead of default allocator on macOS, if I think right, it should result in a bit faster and saner memory-wise libc++. I'm not sure how to do that, I can imagine that linking tbbmalloc statically won't do that so I ask for help to achieve this.

doesn't malloc replacement feature work for you?

Not saying it's not working, but DYLD_INSERT_LIBRARIES is skipped with SIP enabled on El Captain+ if I'm not missing something and I'm looking for a more system solution.

Hello, did you try to link with proxy to avoid env variable usage?

Can you ask someone who knows more to respond to my 1st post? Libc++ doesn't have main() AFAIK. :)

[Vladimir_P_1234567890]

hmm, why you are looking for main() function in libc++? the article says that you need to link your executable file with proxy.

Hi Marky,

Vladimir is right that replacing the memory manager for particular applications of interest (instead of the standard library) is generally a preferred approach.

If you nevertheless wish to make libc++ use tbbmalloc internally, perhaps you should first get some advice from the libc++ community about how to replace malloc with any other memory manager when building libc++.
