gperftools not installing -lprofiler on Mac after installing it with brew

Question

Recently I wanted to profile my cpp code and came across gperftool, but there aren't really clear instructions on how to use it with Mac. So far I have run brew install gperftools and wanted to compile my simple cpp file which just outputs "Hello world!". I run g++ main.cpp -lprofiler -o main but get error ld: library not found for -lprofiler. I really appreciate it if you could guide me or should me a tutorial where it's easy to follow. Thanks :)

Edit: Currently I am using MacOS with new M1 chip (not sure if that can cause any issue)

Answer 1

So brew didn't install the binaries and that's it.

Follow these steps if you are having a hard time making it work

1. clone https://github.com/gperftools/gperftools
2. run ./autogen.sh
3. run ./configure
4. make && sudo make install
5. you should see some path where the binaries where installed, if you wanna take a look at it to make sure (mine was /usr/local/lib)
6. Profit

Answer 2

There is another option. You can identify brew package location by calling

brew info gperftools

==> gperftools: stable 2.13 (bottled), HEAD
Multi-threaded malloc() and performance analysis tools
https://github.com/gperftools/gperftools
/opt/homebrew/Cellar/gperftools/2.13 (101 files, 4.5MB) *
...

Then you only need to specify the location of the library and header files for the compiler. This can be done using CMake this way:

target_include_directories(Target PRIVATE /opt/homebrew/Cellar/gperftools/2.13/include)
target_link_directories(Target PRIVATE /opt/homebrew/Cellar/gperftools/2.13/lib)
target_link_libraries(Target PRIVATE profiler)

Answer 3

I found you can also use the -L$(brew --prefix gperftools)/lib flag to tell g++ where to look for the libraries if you don't want to install with make.
