Re: [icu-support] building icu with clang and -std=c++11

[Vadym K. <vk...@se...>]

Dmitry,

here is how I achieved this on Linux:

    cd <ICU build dir> # ICU source is in "../icu-src"
    export CFLAGS="-DU_CHARSET_IS_UTF8=1 -DU_GNUC_UTF16_STRING=1"
    export CXXFLAGS="-std=gnu++0x  -DU_CHARSET_IS_UTF8=1
    -DU_GNUC_UTF16_STRING=1 -DU_HAVE_CHAR16_T=1"
    export LDFLAGS="-std=gnu++0x"
    ../icu-src/icu/source/runConfigureICU Linux --prefix=<ICU bin dir>
    --with-data-packaging=library --enable-strict=no

    gmake -j4
    gmake check
    gmake install


Hope this helps,
Vadym
