gcov ./summer-proj覆盖测试

编译开关-ftest-coverage -fprofile-arcs

改run.sh  换行类型

apt-get install ./libimagequant0_2.12.2-1.1_amd64.deb

apt-get install ./libimagequant-dev_2.12.2-1.1_amd64.deb

dpkg-deb -c quantum6.deb

泄露分析,编译链接-g

valgrind --tool=memcheck --leak-check=full --show-leak-kinds=all ./bin/Perf

valgrind --tool=callgrind ../bin/Perf

python gprof2dot.py -f callgrind -n10 -s callgrind.out.31113 | dot -Tpng -o valgrind.png

pprof安装

export CPUPROFILE_FREQUENCY=1

go install github.com/google/pprof@latest

pprof --text ./Perf test_capture.prof > profile.txt

pprof --callgrind ./Perf test_capture.prof > callgrind.res

pprof  ./Perf test_capture.prof --web

pprof  ./Perf test_capture.prof --pdf > prof.pdf

查看-pg是否生效

-lc_p

nm libobjectmodule.so | grep mcount

ldd ./Perf | grep libc

apt-get install libpopt-dev

apt-get install libiberty-dev

apt-get install libfdt-dev
