If you don't need to build a static binary (and you probably don't), you need to install the other dependencies as per the instructions: https://github.com/Bitcoin-ABC/bitcoin-abc/blob/master/doc/build-unix.md, see:
Now, you can either build from self-compiled [depends](https://github.com/Bitcoin-ABC/bitcoin-abc/blob/master/depends/README.md) or install the required dependencies with the following instructions..

But since you are running Ubuntu 20.04 there is an easier solution, installing via our PPA: https://launchpad.net/~bitcoin-abc/+archive/ubuntu/ppa/

hi thanks but i need to install it via git . you don't know what's wrong

[david739]

there really isn't anyone here who can get bitcoin-abc working

[Fabcien]

I pointed you to the instructions in the above comment. Did you install all the dependencies as indicated in the doc ? That's why your build fails, because you don't have the dependencies.

[david739]

yes i tried it doesn't work we have modified the procedure above as we did the installation. same error can you please send me a working procedure or edit mine

[Fabcien]

The procedure in your first post is still missing most of the dependencies, you need to install them. Eventually you can disable them if you're sure you don't need them.
The actual error tells you that you're missing jemalloc. From that same document, you can install it via:
sudo apt-get install libjemalloc-dev
or disable it by adding -DUSE_JEMALLOC=OFF to the cmake command line.

Just do the same for each dependency listed in the document.
