给出这个问题的答案,Embed Python in Makefile to set make variables哪个有效!在
define NEWLINE
endef
define PYTHON_SCRIPT_CODE
import sys
print("hi")
endef
SDK_PATH := $(shell echo \
'$(subst $(NEWLINE),@NEWLINE@,${PYTHON_SCRIPT_CODE})' | \
sed 's/@NEWLINE@/\n/g' | python -)
default:
@echo 'SDK Path Detected: $(SDK_PATH)'
如何将数据管道到python std?例如:
^{pr2}$将输出:
SDK Path Detected: hi
GNU bash, version 4.4.19(1)-release (x86_64-pc-linux-gnu)

现在,我要做的是:
define NEWLINE
endef
BASH_VERSION := $(shell bash --version)
define PYTHON_SCRIPT_CODE
import sys
print("Hi")
print("${BASH_VERSION}")
endef
SDK_PATH := $(shell echo \
'$(subst $(NEWLINE),@NEWLINE@,${PYTHON_SCRIPT_CODE})' | \
sed 's/@NEWLINE@/\n/g' | python -)
default:
@echo 'SDK Path Detected: $(SDK_PATH)'
结果:(无新品系)
相关问题:
一个新的例子,没有把东西放进Python脚本中:
#!/usr/bin/make -f
ECHOCMD:=/bin/echo -e
SHELL := /bin/bash
define NEWLINE
endef
VERSION := $(shell bash --version)
# With this, you cannot use single quotes inside your python code
define PYTHON_VERSION_CODE
import re, sys;
program_version = """${VERSION}"""
match = re.search("Copyright[^\d]+(\d+)", program_version);
if match:
if int( match.group(1) ) >= 2018:
sys.stdout.write("1")
else:
sys.stdout.write( match.group(1) )
else:
sys.stdout.write("0")
endef
# Due to this, you cannot use single quotes inside your python code
PYTHON_SCRIPT_RESULTS := $(shell echo \
'$(subst $(NEWLINE),@NEWLINE@,${PYTHON_VERSION_CODE})' | \
sed 's/@NEWLINE@/\n/g' | python -)
all:
printf 'Results: %s\n' "${PYTHON_SCRIPT_RESULTS}"
结果:
对我来说,规避所有命令行引用问题的最简单方法是使用GNUmake的
$(file )
函数将代码写入一个文件。您甚至可以使用#
