为 Windows 交叉编译 binutils-gdb 时出错

如何解决为 Windows 交叉编译 binutils-gdb 时出错

我在 linux 机器 (Ubuntu) 上从这里（主分支）克隆了 binutils-gdb 存储库，我想为 Windows 编译它（使用 x86_64_w64_mingw32 工具链）。

首先，我使用以下选项运行 ./configure 以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 typedef 定义为 long long int（64 位整数）有关，但是，函数 os_time 从文件 sim/common/callback.c:414（相对于项目根目录的路径），采用 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？或者是否有针对 binutils-gdb 的问题跟踪器？

解决方法

这是因为您正在构建当前的非发布开发版本 - 在我克隆存储库 0a703a4cedffa6f3824e87f115e8d392e32de191 时从最新的 git 修订版构建时，我遇到了完全相同的错误。

如果您真的想从开发树中构建，您将不得不等待问题得到解决，或者自己解决 - 本答案中没有解决这个问题。

但如果构建最新发布的版本 2.36.1 就足够了，以下过程将起作用（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
../binutils-2.36.1/configure --prefix=$(pwd)/binutils-2.36.1-x86_64-w64-mingw32 --target=arm-none-eabi --program-prefix=arm-none-eabi- --host=x86_64-w64-mingw32
make
make install

在签出 binutils-2_36_1 标签后，我没有从 git 存储库测试构建：

git -C binutils-gdb checkout binutils-2_36_1

但它应该可以工作，如果标记的内容是存档文件中打包的内容，应该是这种情况。
