我试图从源代码构建Open MPI 3.0.0。我使用的是英特尔编译器版本18.0.0 20170811.环境是Arch Linux。

为什么Open MPI出现icc不符合C99的问题？

Answer 1

如果与glibc 2.26结合使用，最新的ICC似乎有问题。版本18.0.0仍然存在此问题。目前，修复方法是包含标记rspString = Unirest.post(Endpoint) .header("Content-Type", "application/json") .body(createjson(user)) .asString().getBody(); public String createjson(user) { ObjectMapper objectMapper = new ObjectMapper(); String json = objectMapper.writerWithDefaultPrettyPrinter().writeValueAsString(obj); return json; }：

-D_Float128=__float128

Answer 2

如果您不需要使用经典的C ++，则可以选择使用C99进行编译

../configure C99=icc CXX=icpc FC=ifort

使用icc打开MPI：＆＃34; Open MPI需要C99编译器＆＃34;
