windows 交叉编译 binutils-gdb 时出错

Question

我在 linux 机器 (Ubuntu) 上从这里 (master b运行ch) 克隆了 binutils-gdb 存储库，我想为 [=34] 编译它=]（使用 x86_64_w64_mingw32 工具链）。

首先，我运行./configure用下面的选项来指定交叉编译工具链。

./configure --prefix=/usr/x86_64-w64-mingw32 --target=arm-none-eabi --host=x86_64-w64-mingw32

然后我运行 make 并得到以下错误（我省略了大部分输出，因为它非常大）：

[...]

我认为这与 time_t 在主机平台 (Windows) 中被类型定义为 long long int（64 位整数）有关，但是，函数os_time 来自文件 sim/common/callback.c:414（相对于项目根目录的路径），接受一个 long（32 位整数）作为参数：

static long
os_time (host_callback *p, long *t)
{
  return wrap (p, time (t));
}

我该如何解决这个错误？或者 binutils-gdb 是否有任何问题跟踪器？

这是因为您正在构建当前的非发布开发版本 - 我在克隆存储库时从最新的 git 版本构建时遇到了完全相同的错误，0a703a4cedffa6f3824e87f115e8d392e32de191.

如果你真的想从开发树构建，你将不得不等待问题被修复，或者自己修复它——这个答案没有解决。

但如果构建最新发布的版本 2.36.1 就足够了，则此后的过程将起作用（在 Ubuntu 20.04 TLS 上测试）：

wget https://ftp.gnu.org/gnu/binutils/binutils-2.36.1.tar.gz
tar zxf binutils-2.36.1.tar.gz
mkdir binutils
cd binutils

make install

签出 binutils-2_36_1 标签后，我没有测试从 git 存储库构建：

git -C binutils-gdb checkout binutils-2_36_1

但它应该可以工作，如果标记的是打包在存档文件中的内容，应该是这种情况。
