Any plan to shift to CMake? #677

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Spent yesterday hacking TCMalloc into our SWIG'd C++ Java libraries. Saw a 
whopping 20x performance increase for an 8 thread test case. The large 
performance increase is because we force all C++ memory allocations to allocate 
memory from the Java heap to adhere to the -Xmx JVM flag. 

Unfortunately, the work isn't very portable to Windows since TCMalloc's 
automake build system isn't compatible with our CMake build system. I ended up 
following the Chromium project's lead and simply copied in the necessary 
config.h and tcmalloc.h headers to get it to work. 

Is there any plan, or does anyone know of a CMakeLists.txt that works for 
TCMalloc? Rather not re-invent the wheel. 

Also, would TCMalloc be interested in a configuration mode that uses the JVM as 
a SysAllocator?

I don't have any plans to switch to CMake. Some _additional_ lightweight 
tcmalloc-minimal-only cmakefile might be useful thing to contribute though.

Regarding SysAllocator implementation works with JVM I think it's best to keep 
it separate from tcmalloc. I.e. it's very niche thing which we won't be able to 
maintain in meaningful way.

Yes, please; a cmake build script would enable me to use this library much more 
easily.  There's no reason to pin the build environment to Linux more than is 
necessary.

Let me repeat myself then :) Please contribute cmake build.

With an attitude like that, I consider that unlikely.

I sense misunderstanding. What's wrong with me not liking cmake but willing to 
accept (and maintain) contributed cmake build ?
