syntax error near unexpected token '(' in bash script when selecting files [extend]-CodePudding

Question similar to here, but for my use case, I'd like to place inside the makefile.

#!/bin/bash

# Example: 
#   make run TEST_CASE="testbench.sv"
#   make clean

compile:
    vcs $(TEST_CASE) -sverilog;

run: compile
    ./simv

uvm_compile:
    vcs $(TEST_CASE) -sverilog;

clean:
    shopt -s extglob;
    rm -v !(*.sv|*svh|"makefile");

The problem exist in make clean, and I got the following result:

ycliao@localhost:[~/workspace/i2c_vip/uvm_practice]: make clean
shopt -s extglob;
rm -v !(*.sv|*svh|"makefile");
/bin/sh: -c: line 0: syntax error near unexpected token `('
/bin/sh: -c: line 0: `rm -v !(*.sv|*svh|"makefile");'
make: *** [clean] Error 1

CodePudding user response：

As I understand makefiles, every line is executed in a separate shell. So you need to add a line continuation to concatenate the commands so that they execute in the same shell:

SHELL = /bin/bash

# ...

clean:
    shopt -s extglob; \
    rm -v !(*.sv|*svh|"makefile");

This is demonstrated in Example makefiles on the wikipedia Make page.
