器件型号：AM62P

工具与软件：

您好！

由于 SDK 中缺少32位库头arago-2023.10-toolchain-2023.10.sh,我们在编译应用程序时遇到了致命的构建错误。这些错误会阻止编译过程并阻止应用程序启动。

构建错误表示不存在以下32位库标头：

bits/typesizes-32.h
bits/timesize-32.h
bits/long-double-32.h
bits/floatn-32.h
bits/endian-32.h
bits/endianness-32.h
bits/pthreadtypes-32.h
bits/pthreadtypes-arch-32.h
bits/struct_rwlock-32.h
bits/setjmp-32.h
bits/local_lim-32.h

平台详细信息：

架构： 64位
多尔蒂利布： 使能
SDK： arago-2023.10-toolchain-2023.10.sh

即使在我们的环境中启用了 multilib 支持、并且系统架构为64位、也会发生错误。所需的32位库似乎缺失或未正确包含在 SDK 中。

您能否帮助我们了解这些标题缺失的原因、并提供有关如何解决此问题的指导？如果需要额外步骤以确保64位平台的32位兼容性、请提供详细信息。

您好、Angelin：

您的工作所依据的是哪种确切的 SDK 版本？

您是否有可以根据显示典型故障的 Devkit 构建的"最小应用程序"？也许只是一个包含您期望的标头文件的基本 main.c 文件那样简单吗？

此致、Andreas

尊敬的 Andreas：

我们的工作使用以下 SDK 版本：

Yocto 配置使用 ：processor-sdk-scarthgap-10.00.07.04-config.txt
版本： 10.00.07.04
SDK 版本： arago-2023.10-toolchain-2023.10.sh
地点： /opt/arago-2023.10

下面是最小值 C++应用程序创建的 main.cpp()timesize-32.h在timesize.h文件中重现与之相关的问题：

#include
#include

int main(){
std：：cout <<"Testing timesize.h Include"<< std：endl；
返回0；
}

当我们尝试使用 SDK 编译该 C++应用程序时、会出现以下错误：

/opt/arago-2023.10/sysroots/aarch64-oe-linux/usr/include/bits/timesize.h:23:10: fatal error: bits/timesize-32.h: No such file or directory
   23 | #include <bits/timesize-32.h>
      |          ^~~~~~~~~~~~~~~~~~~~
compilation terminated.

问题似乎源于timesize.h尝试timesize-32.h根据__WORDSIZE定义包含的逻辑：

#include <bits/wordsize.h>

#if __WORDSIZE == 32

#ifdef _MIPS_SIM

#if _MIPS_SIM == _ABIO32
#include <bits/timesize-32.h>
#elif _MIPS_SIM == _ABIN32
#include <bits/timesize-n32.h>
#else
#error "Unknown _MIPS_SIM"
#endif

#else /* _MIPS_SIM is not defined */
#include <bits/timesize-32.h>
#endif

#elif __WORDSIZE == 64
#include <bits/timesize-64.h>
#else
#error "Unknown __WORDSIZE detected"
#endif /* matches #if __WORDSIZE == 32 */

尽管我们的平台是64位的,但构建尝试包含timesize-32.h SDK 中缺少的32位特定标头。

如果您需要更多详细信息或其他示例、请告诉我。

此致、

Angelin Christy

您好、Angelin：

我刚刚在 SDK v10.1的环境中进行了此尝试、但在构建小示例程序时没有问题、请参阅以下步骤：

# Create test source
a0797059@jiji:~/ti/ti-processor-sdk-linux-am62pxx-evm-10.01.10.04/linux-devkit
$ cat <<EOF > main.cpp
> #include <bits/timesize.h>
#include <iostream>

int main() {
std::cout << "Testing timesize.h inclusion" << std::endl;
return 0;
}
> EOF

# Double-check test source
a0797059@jiji:~/ti/ti-processor-sdk-linux-am62pxx-evm-10.01.10.04/linux-devkit
$ cat main.cpp
#include <bits/timesize.h>
#include <iostream>

int main() {
std::cout << "Testing timesize.h inclusion" << std::endl;
return 0;
}

# Source the devkit environment
a0797059@jiji:~/ti/ti-processor-sdk-linux-am62pxx-evm-10.01.10.04/linux-devkit
$ source environment-setup

# Build test code

您是否可以尝试重新创建此文件？
