Have a look at colormake, found here
看看colormake，找到here
$ apt-cache search colormake
colormake - simple wrapper around make to colorize output
Using the power of google, I also found this bash-function.
借助 google 的力量，我也找到了这个 bash 函数。
make()
{
pathpat="(/[^/]*)+:[0-9]+"
ccred=$(echo -e "3[0;31m")
ccyellow=$(echo -e "3[0;33m")
ccend=$(echo -e "3[0m")
/usr/bin/make "$@" 2>&1 | sed -E -e "/[Ee]rror[: ]/ s%$pathpat%$ccred&$ccend%g" -e "/[Ww]arning[: ]/ s%$pathpat%$ccyellow&$ccend%g"
return ${PIPESTATUS[0]}
}

I have came to this questions searching for a solution to colorize makeoutput and then remembered a while back I have researched a good generic log colorizer and found ccze. It works with anything I throw at it from Minecraft server logs to Exim MTA.
我遇到了这个问题，正在寻找一种对make输出着色的解决方案，然后想起不久前我研究了一个很好的通用日志着色器，发现ccze. 它适用于我从 Minecraft 服务器日志到 Exim MTA 抛出的任何内容。
make | ccze -A
make | ccze -A
NOTE: specifying -A option enables 'raw-ansi' otherwise some output is 'cleared' at end of run in my experience.
注意：指定 -A 选项会启用“raw-ansi”，否则根据我的经验，在运行结束时会“清除”某些输出。

If you're an emacs user, you can use the command M-x compile. This puts the make output in a highlighted buffer, with errors acting as links to the relevant line in the source code.
如果您是 emacs 用户，则可以使用命令M-x compile. 这会将 make 输出放在突出显示的缓冲区中，错误将作为指向源代码中相关行的链接。

Just another bash function , much concise
只是另一个 bash 函数，非常简洁
make()
{
/usr/bin/make "$@" 2>&1 | sed -E -e "s/error/ $(echo -e "\033[31m" ERROR "\033[0m"/g)" -e "s/warning/ $(echo -e "\033[0;33m" WARNING "\033[0m"/g)"
return ${PIPESTATUS[0]}
}

How about the following?
以下情况如何？
It is produced by a simplified version of this Makefile.
它是由这个 Makefile的简化版本产生的。
PROJECT = programname
SHELL = /bin/bash
OBJS = $(patsubst src/%.cc,obj/%.o,$(wildcard src/*.cc))
RESET = 3[0m
make_std_color = 3[3m # defined for 1 through 7
make_color = 3[38;5;m # defined for 1 through 255
WRN_COLOR = $(strip $(call make_std_color,3))
ERR_COLOR = $(strip $(call make_std_color,1))
STD_COLOR = $(strip $(call make_color,8))
COLOR_OUTPUT = 2>&1 | \
while IFS='' read -r line; do \
if [[ $$line == *:[\ ]error:* ]]; then \
echo -e "$(ERR_COLOR)$${line}$(RESET)"; \
elif [[ $$line == *:[\ ]warning:* ]]; then \
echo -e "$(WRN_COLOR)$${line}$(RESET)"; \
else \
echo -e "$(STD_COLOR)$${line}$(RESET)"; \
fi; \
done; exit $${PIPESTATUS[0]};
.PHONY: $(PROJECT)
$(PROJECT): bin/$(PROJECT)
bin/$(PROJECT): $(OBJS)
@mkdir -p bin
@echo g++ -o $@ $(OBJS) -Iinclude
@g++ -o $@ $(OBJS) -Iinclude $(COLOR_OUTPUT)
obj/%.o: src/%.cc
@mkdir -p obj
@echo g++ -o $@ -c $< -Wall -Wextra
@g++ -o $@ -c $< -Wall -Wextra $(COLOR_OUTPUT)
It assumes all C++ source files are in the srcdirectory (extention .cc) and header files are in the includedirectory.
它假设所有 C++ 源文件都在src目录中（扩展名 .cc），头文件在include目录中。

On Mac, it worked by printing tputcolor codes around the error string.
在 Mac 上，它通过tput在错误字符串周围打印颜色代码来工作。
First export tputcolor codes as below:
第一个export tput颜色代码如下：
export red=`tput setaf 1`
export reset=`tput sgr0`
then, add a target to Makefile as below:
然后，将目标添加到 Makefile，如下所示：
...
check-env:
ifndef ENV
$(error ${red}ENV is undefined. Please export it using command [ export ENV=dev ]${reset})
endif
...
then, run it as make check-env
然后，运行它 make check-env
