trying to compile php with gcov

installing gcov and ltp for php.md

vagrant@php7dev:~/php-src$ ./configure --enable-gcov --prefix=/usr/local/php70-gcov

gives, eventually:

configure: error: To enable code coverage reporting you must have LTP installed

apt-get install ltp doesn't work. So then

vagrant@php7dev:~$ mkdir ~/ltp
vagrant@php7dev:~$ cd ~/ltp
vagrant@php7dev:~/ltp$ wget https://github.com/linux-test-project/ltp/archive/20150119.tar.gz
vagrant@php7dev:~/ltp$ tar -zxvf ./20150119.tar.gz 
vagrant@php7dev:~/ltp$ cd ltp-20150119/
vagrant@php7dev:~/ltp/ltp-20150119$ ./configure
vagrant@php7dev:~/ltp/ltp-20150119$ make all
vagrant@php7dev:~/ltp/ltp-20150119$ make install

Now that appears to do something (there's lots in /opt/ltp) but ./configure --enable-gcov --prefix=/usr/local/php70-gcov still says 'you must have LTP installed'.

?

Goot insight.

notes to self now现在给自己的笔记

apt-get install lcov

works, and satisfies the php-src$ ./configure --enable-gcov --prefix=/usr/local/php70-gcov command.有效，并满足 php-src$ ./configure --enable-gcov --prefix=/usr/local/php70-gcov 命令。

Now trying 现在正在尝试

php-src$ make all && make install

let's see what happens...让我们看看发生了什么...

works!
