I am trying to install shc on Ubuntu 18.04

wget http://www.datsi.fi.upm.es/~frosal/sources/shc-3.8.9b.tgz

tar xvfz shc-3.8.9.tgz

cd shc-3.8.9

make

But receive the following error:

cc -Wall  shc.c -o shc

make: cc: Command not found

makefile:31: recipe for target 'shc' failed

make: *** [shc] Error 127

The makefile:

# Makefile

    install -c -s shc $(INSTALL_PATH)/bin/

clean:

    rm -f *.o *~ *.x.c



cleanall: clean

    rm -f shc *.x

I have no idea how to fix this error. Can anyone help?

cc is an alias for the GNU C compiler (gcc). You can install it as follows:

 sudo apt install gcc

If, for some reason, the gcc compiler is already installed, but the symbolic link /usr/bin/cc is missing, you can also do:

 make CC=gcc

sudo apt install build-essential

This will install a C compiler (providing the cc command) as well as other tools that you may need for building software from source.
