I have a makefile rule in while I am executing a linux tool. I need to check the exit status of the tool command, and if that command fails the make has to be aborted.
I tried checking with $?, $$? \$? etc in the makefile. But they gives me syntax error when makefile runs.
What is the right way to do this ?
Here is the relevant rule in Makefile
if [ $$? -ne 0 ] \
echo "mycommand failed" \
