Install tcmalloc on CentOS

Question

I installed tcmalloc on CentOS using the command:

sudo yum install google-perftools

And it proceeds correctly. But I cannot find any installed perftools libraries in /usr/lib/, so I cannot set LD_PRELOAD variable.

Then, when I tried to compile with flag -ltcmalloc, the compiler did not recognize it, which quite made sense.

What else should I specify to use tcmalloc on CentOS? Thanks.

Do you have a `tcmalloc (3)` man page? CentOS is pretty good about supplying docs and they are usually pretty good. — jww, Aug 30 '18 at 20:51
According to [gperftools](https://github.com/gperftools/gperftools) you link `-ltcmalloc` or `-ltcmalloc_minimal`. But I can't find it searching in `/lib` or `/lib64` (`find /lib64 -name '*tcmalloc*'`). — jww, Aug 30 '18 at 21:02
@jww I tried that, but I got `/usr/bin/ld: cannot find -ltcmalloc` — hiimdaosui, Aug 30 '18 at 21:04
[`dnf repoquery -l gperftools`](https://stackoverflow.com/a/107520/608639) shows the package is empty. It sucks to be you right about now :) — jww, Aug 30 '18 at 21:08
Lets see if anything interesting drops out from [Fedora package contains no files?](https://unix.stackexchange.com/q/465857/56041) — jww, Aug 30 '18 at 21:15
@jww I really appreciate that! Hope we could figure this out. — hiimdaosui, Aug 30 '18 at 21:37

The package names have changed a little. Just run:

yum install gperftools gperftools-devel

...and you'll find various libtcmalloc files in /usr/lib64/

You can always build from source. I have done that with my centos 8.

Source code can be found here: https://github.com/google/tcmalloc. Be aware you will need bazel for building the project.
