Possible reasons follow:1. Perl is not installed2. apxs was not found. Try to pass the path using –with-apxs2=/path/to/apxs3. Apache was not built using –enable-so (the apxs usage page is displayed)
解决方案：查找httpd安装目录下的bin目录里的 apxs ,尽量不要写/usr/bin/apxs
由于Mac自带的openssl没法升级（我没找到升级的办法），导致版本较低，报错：configure: error: OpenSSL version 1.0.1 or greater required.
解决方案：由于Mac自带的openssl没法升级（我没找到升级的办法），用
brew install openssl
安装最新版的openssl，然后在参数中加上brew安装的ssl的路径
–with-openssl=/usr/local/Cellar/openssl@1.1/1.1.0e–with-gettext报错configure: error: Cannot locate header file libintl.h
解决方案：
brew install gettext
打开PHP的 configure文件，修改文件的
for i in $PHP_GETTEXT /usr/local /usr/ ;do
改成
for i in $PHP_GETTEXT /usr/local /usr/ usr/local/opt/gettext;dolibiconv问题，报错如下：checking for iconv… nochecking for libiconv… noconfigure: error: Please specify the install prefix of iconv with –with-iconv=<DIR>
解决方案：安装 libiconv (字符编码转换库)网站地址: http://www.gnu.org/software/libiconv/当前版本: https://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.15.tar.gz
$ wget [https://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.15.tar.gz$ tar zxvf libiconv-1.15.tar.gz$ cd libiconv-1.15$ ./configure –prefix=/usr/local/lib/libiconv$ make$ sudo make install
安装
make && sudo make install
