php - 'UnicodeString' 未在此范围内声明

Question

无法编译 php国际 (php - 5.5.9，ubuntu - 14.04，icu - 67)

当我尝试 pecl 安装国际 ，出现以下错误

In file included from /tmp/pear/temp/intl/intl_convertcpp.cpp:21:0:
/tmp/pear/temp/intl/intl_convertcpp.h:28:25: error: 'UnicodeString' was not declared in this scope
 int intl_stringFromChar(UnicodeString &ret, char *str, int32_t str_len, UErrorCode *status);
                         ^~~~~~~~~~~~~
/tmp/pear/temp/intl/intl_convertcpp.h:28:25: note: suggested alternative:
In file included from /tmp/pear/temp/intl/intl_convertcpp.h:26:0,
                 from /tmp/pear/temp/intl/intl_convertcpp.cpp:21:
/opt/icu67/include/unicode/unistr.h:294:20: note:   'icu_67::UnicodeString'
 class U_COMMON_API UnicodeString : public Replaceable
                    ^~~~~~~~~~~~~

请告诉我如何克服这个错误

或者其他方式来更新 icu 数据库，因为 易于获取 放置一个非常旧的数据库。

使用 icu_67::UnicodeString 而不是 UnicodeString 并且您的问题得到解决。
