I am not able to make out how to fix this.
i followed https://chromium.googlesource.com/chromium/src/+/master/docs/linux_build_instructions.md
also referred these
https://groups.google.com/a/chromium.org/forum/#!topic/chromium-os-dev/360e3QsLH-8
https://groups.google.com/a/chromium.org/forum/#!msg/chromium-os-dev/nM7Af-sJP_I/YoqXPgZ0BQAJ
Not able to get much details.
These discussions refer to PKG_CONFIG_LIBDIR but its not clear where to set this value or use it exactly.
Any inputs on what i may be missing ?

Answer 1

I had the same issue resolved it by installing this packages
sudo apt-get update && sudo apt-get install pkg-config

Answer 2

I had the same issue, and I also tried with sudo apt-get update && sudo apt-get install pkg-config as mentioned by #Rajan Palani and many other git issues comments.
But in my case
sudo apt install libpango1.0-dev
sudo apt install libcogl-pango-dev
sudo apt install libjpeg-dev
above commands helps me out to solve the issue
