前几天，我安装了 Intel 的编译器和与 Parallel Studio 捆绑在一起的应用程序，如果不使用 icc，我就无法编译。使用 gcc、clang 或 mpicc 时，我收到以下错误：
In file included from z.main.c:13:0:
/opt/intel/include/math.h:29:3: error: #error "This Intel <math.h> is for
use with only the Intel compilers!"
# error "This Intel <math.h> is for use with only the Intel compilers!"
^
main
通常我必须math.h使用 链接到库-lm，这适用于其他文件。我测试过的其他情况不包括mpi.h，如果有关系的话。
我不想卸载英特尔编译器；我希望在通过 ssh 进行远程工作之前，先解决本地遇到的任何问题。
更新
我跑去gcc fvm.c -c --trace -lm看看它在哪里寻找数学库。结果如下：
gcc z.fvm.c -c --trace -lm

我如何告诉 gcc、mpicc 在哪里查找并忽略英特尔数学库？
提前致谢。
答案1
Intel header 是兼容的，但需要做一点小改动。首先，你需要关闭错误源。
//#if !defined(__INTEL_COMPILER)
//# error "This Intel <math.h> is for use with only the Intel compilers!"
//#endif
那么您应该包括缺少的标题。
#include <features.h>
