mpicc在编译时没有警告 [英] mpicc with no warning when compiling
问题描述
我想知道使用什么标志,以避免在使用mpicc编译C / C ++并行时出现警告消息。更具体地说,我不想让我的消息屏幕引用未使用的变量,例如。警告:未使用的变量
I would like to know what flag to use in order to avoid warning messages that appear when compiling a C/C++ parallel using mpicc. More specifically, I prefer not to have my screen of messages referring to unused variables,e.g. warning: unused variable

推荐答案
Mark, mpicc
只是一个真正的编译器工具链的包装器。有一个几乎标准的选项(几乎)所有包装器理解: -showme
。它显示了什么标志传递给编译器,例如:
As pointed by High Performance Mark, mpicc
is simply a wrapper around the real compiler toolchain. There is an almost standard option that (almost) all wrappers understand: -showme
. It shows you what flags exactly get passed on to the compiler, e.g.:
$ mpicc -showme
icc <lots of preprocessor flags> -fexceptions -pthread \
<lots of linker flags> -lmpi -losmcomp -lrdmacm -libverbs -lrt \
-lnsl -lutil -lpsm_infinipath -lbat -llsf -ldl -lm -lnuma
检查这些选项,请查看您的编译器手册,了解如何抑制警告。
Examine these options, consult your compiler's manual and find out how to suppress the warnings.
