Question

我尝试按照说明从github上的README.md文件为MacOSX（yosemite）构建leon。

除了当我运行基本测试时，我遇到了一个未找到scalaz3库的问题：

我试图从EPFL构建ScalaZ3软件包，这需要构建Microsoft的Z3（来自github）。构建z3本身可以找到，但构建ScalaZ3失败了，缺少“gomp”库：

[error] ld: library not found for -lgomp
[error] clang: error: linker command failed with exit code 1 (use -v to see invocation)
[info] Bundling files:

我发现这里有一个用于MacOSX的Clang OMP库：

http://brewformulas.org

但是，这可能需要调整一些构建脚本以指向brew安装clang-omp。

有没有人遇到类似问题或解决过这些问题？

以下是我在OSX上运行最新版Leon的步骤：

git clone git@github.com:epfl-lara/leon.git
cd leon
git remote add osx git@github.com:mantognini/leon.git
git fetch osx
git checkout osx
git rebase origin/master # adds precompiled OSX binaries
sbt clean compile script

确保将leon二进制文件与$PATH相关联，例如在最后一步运行ln -sv $(pwd)/leon /usr/local/bin/leon之后。

要将二进制文件更新为最新版本的Leon，请运行

git fetch origin
git rebase origin/master
sbt clean compile script

假设您在osx分支。

如何为MacOSX构建leon？
