openharmony 交叉编译openjdk报错

openjdk17,ubuntu20.04,OHOS (dev) clang version 15.0.4

configure 命令为

./configure --openjdk-target=aarch64-linux --with-toolchain-type=clang --with-debug-level=slowdebug1.

错误信息如下：

从你提供的错误信息来看，主要有以下几个问题：

交叉编译工具链中的某些工具（如 aarch64-linux-ld、aarch64-linux-ar 等）未找到。

配置脚本找到了 GCC 编译器，但找不到 Clang 编译器。

为了解决这些问题，可以按照以下步骤进行操作：

1. 安装并设置交叉编译工具链

确保安装了合适的 AArch64 交叉编译工具链。可以通过以下命令安装：

sudo apt-get update
sudo apt-get install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu binutils-aarch64-linux-gnu1.
2.

2. 安装并设置 Clang 编译器

确保安装了 Clang 编译器，并将其路径添加到 PATH 环境变量中：

sudo apt-get install clang-15
export PATH=/path/to/clang/bin:$PATH1.
2.

3. 设置环境变量

在运行 configure 脚本之前，确保设置好所有必要的环境变量。例如：

export AR=aarch64-linux-gnu-ar
export LD=aarch64-linux-gnu-ld
export NM=aarch64-linux-gnu-nm
export STRIP=aarch64-linux-gnu-strip
export OBJCOPY=aarch64-linux-gnu-objcopy
export OBJDUMP=aarch64-linux-gnu-objdump
export CC=clang
export CXX=clang++1.
2.
3.
4.
5.
6.
7.
8.

4. 运行 configure 脚本

运行 configure 脚本时，使用参数指定 Clang 编译器路径和其他相关设置：

./configure --openjdk-target=aarch64-linux --with-toolchain-type=clang --with-debug-level=slowdebug --with-tools-dir=/path/to/clang/bin1.

示例配置

假设 Clang 编译器位于 /usr/bin，可以使用以下命令：

export AR=aarch64-linux-gnu-ar
export LD=aarch64-linux-gnu-ld
export NM=aarch64-linux-gnu-nm
export STRIP=aarch64-linux-gnu-strip
export OBJCOPY=aarch64-linux-gnu-objcopy
export OBJDUMP=aarch64-linux-gnu-objdump
export CC=/usr/bin/clang
export CXX=/usr/bin/clang++1.
2.
3.
4.
5.
6.
7.
8.

./configure --openjdk-target=aarch64-linux --with-toolchain-type=clang --with-debug-level=slowdebug --with-tools-dir=/usr/bin1.

验证环境配置

在运行 configure 前，可以通过以下命令验证是否正确配置了环境变量：

echo $CC  # 应输出 /usr/bin/clang
echo $CXX # 应输出 /usr/bin/clang++
which ${AR} # 应输出路径 /usr/bin/aarch64-linux-gnu-ar 或类似路径
which ${LD} # 应输出路径 /usr/bin/aarch64-linux-gnu-ld 或类似路径1.
2.

4.

如果一切正常，重新运行 configure，它应该能够找到所需的工具和编译器。
