优胜美地的 Clang 版本

Question

我正在尝试在 Mac OS Yosemite（从 Snow Lion 升级）上安装 MeTA 以进行文本检索。

我无法制作该项目。显然，使用的是旧版本的 Clang (3.2)。 我更新了 Xcode 和命令行工具，但没有使用新的 Apple 版本的 clang 来制作项目。

在安装 MeTA 时，我使用了以下命令：

git clone https://github.com/meta-toolkit/meta.git
cd meta/
git reset --hard v1.3.2

# set up submodules
git submodule update --init --recursive

# set up a build directory
mkdir build
cd build
cp ../config.toml .

# configure and build the project
CXX=clang++ cmake ../ -DCMAKE_BUILD_TYPE=Release -DICU_ROOT=/usr/local/opt/icu4c
make

Clang version
clang -v and it displays:
clang version 3.2 (tags/RELEASE_32/final)

Target: x86_64-apple-darwin14.1.0

Thread model: posix

在make 之后出现以下错误：

[  0%] Building CXX object src/util/CMakeFiles/meta-util.dir/progress.cpp.o

Answer 1

我终于通过手动卸载 clang 3.2 解决了我的问题。这使得系统可以识别 Apple 版本的 clang。然后，我重新安装了 cmake。 MeTA 安装顺利，14 项测试全部通过。
