mac libicu-devel安装

Question

php安装intl扩展的时候报错：
configure: error: Unable to detect ICU prefix or no failed. Please verify ICU install prefix and make sure icu-config works
CentOS下直接执行 yum -y install libicu-devel 即可
然而 Mac下没找到 libicu-devel ，而找到了 icu4c
brew install icu4c 之后，再次 configure intl 仍然报同样的错误
求解，谢谢诸位

Answer 2

安装 intl 扩展报错：
configure: error: Unable to detect ICU prefix or no failed. Please verify ICU install prefix and make sure icu-config works
CentOS解决方案：yum -y install libicu-devel
接着继续安装

mac解决方案：
brew install icu4c(仅仅安装这个，configure的时候依然报同样的错误)
brew link icu4c --force
make的时候报错

In file included from ./intl_convertcpp.h:26:
/usr/local/Cellar/icu4c/59.1/include/unicode/unistr.h:3025:7: error: delegating constructors are permitted only in C++11

      ^~~~~~~~~~~~~

···
make: *** [intl_convertcpp.lo] Error 1

解决方案：
打开 /Applications/NMP/src/php-7.1.3/ext/intl/Makefile
搜索 CXXFLAGS = -g -O2 行并添加 -std = c ++ 11

CXX = g++
CXXFLAGS = -g -O2 -std=c++11
CXXFLAGS_CLEAN = $(CXXFLAGS)
重新make，如果修改文件之后，make clean 刚才修改的会被重置
