Question

我正在使用Solaris x86并使用OpenCSW软件包安装了gcc4。下面的简单测试程序将无法编译：

#include <stdio.h>
#include <stdlib.h>

main()
{
   printf("Hello, world\n");
}

如果我没有stdlib.h include，它会构建并运行良好。当stdlib.h在我时，我得到以下错误：

bash-3.00$ g++ -I/opt/csw/include test.cpp
In file included from /opt/csw/gcc4/lib/gcc/i386-pc-solaris2.8/4.3.3/include-    fixed/stdlib.h:27,
                 from test.cpp:2:
/usr/include/iso/stdlib_iso.h:107: error: expected initializer before '__NORETURN'
/usr/include/iso/stdlib_iso.h:124: error: expected initializer before '__NORETURN'
/usr/include/iso/stdlib_iso.h:132: error: multiple parameters named '_RESTRICT_KYWD'

我认为这可能是OpenCSW和默认库之间的某种冲突，但我不确定如何修复它。有人可以帮忙吗？

Answer 1

只需从命令行中删除-I/opt/csw/include。

Answer 2

尝试运行应该成为gcc安装一部分的fixheaders或fixincludes命令之一。根据其名称为Solaris 8构建的gcc软件包与您正在运行的Solaris发行版（可能是Solaris 10或更高版本）之间可能存在不匹配。

Answer 3

无法在没有-I的情况下在Solaris 10 x86上重现：

-bash-3.00$ /opt/csw/gcc4/bin/g++ test.cpp
-bash-3.00$ /opt/csw/gcc4/bin/g++ -v    
Using built-in specs.

不能在Solaris </stdlib.h>上#include <stdlib.h>
