我正在尝试追踪在Sun Studio 12.3下的Solaris 11.3（x64）上产生汇编程序错误"", line 1 : Illegal flag (-)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
系统地去除-xO2、-native、-m64、-Kpic等...无法解决它。我在Mozilla上发现了类似的报告，但是删除调试符号并没有解决它。
汇编程序文件的第一行是.file ... （如下所示），所以我不清楚非法标志来自哪里。
为什么我遇到"", line 1 : Illegal flag (-)，我该如何解决？
添加-v和-keeptmp会产生以下结果。
$ $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不是汇编程序的有效参数。例如，有关接受的参数，请参阅 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Assembler: "", line 1 : Illegal flag (-)。我很确定第 1 行部分是红鲱鱼，所以我直接转到Illegal flag (-)部分，因为这正是如果--divide实际上被解释为-- -d -i -v -i -d -e你会得到的错误，这是 unix 程序解释其参数的完全常见方式。因此，我只是用谷歌搜索了"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。
