adb, android debugging brige, is used for connecting your PC and Android devices to get log, send command to Android devices etc which is very useful for Android software development.
fastboot command is used to control bootloader mode for Nexus devices, it can be used to flash new factory image etc.
Here the method of how to build adb command and fastboot command manually from Android Open Source Project source code is written. If you feel it trouble some to build adb and fastboot command manually in your PC, see also

I used Linux OS (Ubuntu 14.4) for following set up.
Contents
Step 1. Build Environment setup
If your PC does not have building environment for AOSP yet, you can set up by just following Establishing a Build Environment.
Step 2. Downloading AOSP Source code
Follow Downloading the Source.
Step 3. Build adb and fastboot
Go to your source code root directory, and set up build environment by
$ source build/envsetup.sh (or $ . build/envsetup.sh) $ lunch
After lunch command, following will appear so that you can choose your buildtype.
~/workspaces/aosp$ lunch You're building on Linux Lunch menu... pick a combo: 1. aosp_arm-eng 2. aosp_arm64-eng 3. aosp_mips-eng 4. aosp_mips64-eng 5. aosp_x86-eng 6. aosp_x86_64-eng 7. aosp_deb-userdebug 8. aosp_flo-userdebug 9. full_fugu-userdebug 10. aosp_fugu-userdebug 11. aosp_grouper-userdebug 12. aosp_tilapia-userdebug 13. mini_emulator_arm64-userdebug 14. m_e_arm-userdebug 15. mini_emulator_mips-userdebug 16. mini_emulator_x86_64-userdebug 17. mini_emulator_x86-userdebug 18. aosp_flounder-userdebug 19. aosp_hammerhead-userdebug 20. aosp_mako-userdebug 21. aosp_shamu-userdebug 22. aosp_manta-userdebug Which would you like? [aosp_arm-eng]
You can type number and press enter to proceed. In my case, I want to build for Nexus Player so I chose 10 (aosp_fugu-userdebug).
Finally we can build by
$ make adb fastboot
make will takes several minutes to build adb and fastboot.
Step 4. Adding a environment path
Immediately after building, you can find these command by,
$ which fastboot ~/workspaces/aosp/out/host/linux-x86/bin//fastboot $ which adb ~/workspaces/aosp/out/host/linux-x86/bin//adb
It is better to set environment path (because after this log in session finishes, this path setting will be removed).
# Environment path setting for adb & fastboot export PATH=~/workspaces/aosp/out/host/linux-x86/bin/:$PATH
Step 5. Check function
Finally you can check if fastboot and adb is working correctly or not.
adb
First is to check adb, connect your PC and Android device by USB. Enable developer mode for your Android device, and after enable USB debugging, type
$ adb devices
It should show device which PC is connecting to. Try sudo if it is not working.
fastboot
Finally check fastboot. Reboot your Nexus devices with bootloader mode
$ adb reboot bootloader
After Nexus reboots with bootloader mode, type
$ fastboot devices XXXXXXXX fastboot
and check if you can see devices or not. try sudo if it is not working, or it says “waiting for devices” forever. If fastboot is not working, you may need to set up Android device udev rules (refer below links).
