"", line 1 : Illegal flag (-)我正在尝试找出在 Sun Studio 12.3 下的 Solaris 11.3 (x64) 上产生汇编程序错误的问题。Sun Studio 编译器是一种特殊的地狱。

$ echo $CXX
/opt/solarisstudio12.3/bin/CC

$ cat test.cxx
#include <iostream>
int main(int argc, char* argv[])
{
  std::cout << argc << std::endl;
  return 0;
}

$ $CXX -DNDEBUG -xO2 -native -template=no%extdef -m64 -Kpic -Wa,--divide -c test.cxx
Assembler: 
        "", line 1 : Illegal flag (-)
CC: fbe failed for test.cxx

系统地删除-xO2, -native, -m64, -Kpic, 等...并不能解决它。我在 Mozilla 找到了类似的报告，但删除调试符号并没有解决它。

汇编文件的第一行是.file ...（如下所示），所以我不清楚非法标志的来源。

为什么我会遇到"", line 1 : Illegal flag (-)，我该如何解决？

添加-v和-keeptmp结果如下。

$ $CXX -v -keeptmp  -DNDEBUG -xO2 -native -template=no%extdef -m64 -Kpic -Wa,--divide -c test.cxx

您的问题是-Wa,--divide，根据多个来源--divide，这不是汇编程序的有效参数。例如，有关接受的参数，请参见https://docs.oracle.com/cd/E37069_01/html/E54439/fbe-1.html 。

为了得出这个结论，我从你的-v输出开始。我看到的关键行是它在运行 fbe 后立即失败，并且错误是Assembler: "", line 1 : Illegal flag (-). 我很确定第 1 行部分是一个红鲱鱼，所以我直接进入该Illegal flag (-)部分，因为这正是你会得到的错误，如果--divide实际上被解释为-- -d -i -v -i -d -e这是 unix 程序解释其参数的一种完全常见的方式。所以然后我只是用谷歌搜索“fbe 命令行参数”（或类似的东西），看看这是否是一个有效的参数。
