For the running the frida binaries (frida-discover, frida-ps, frida-repl and frida-trace) you need to have python 3.4 installed with the colorama package (pip3 install colorama).
make
First make a trusted codesigning certificate. You can use the guide at https://sourceware.org/gdb/wiki/BuildingOnDarwin in the section "Creating a certificate". You can use the name frida-cert instead of gdb-cert if you want to.
Next export the name of the created certificate to the environment variables MAC_CERTID and IOS_CERTID and run make:
export MAC_CERTID=frida-cert
export IOS_CERTID=frida-cert
make
To ensure that OS X accepts the newly created certificate, restart the taskgated daemon:
sudo killall taskgated
frida.sln
(Requires Visual Studio 2013.)
See http://www.frida.re/docs/building/ for more details.
You may also download pre-built binaries for various operating systems from http://www.frida.re/.
Currently there is only a make install target for Mac.
make install
