Receiving SIGABRT on Raspi when trying to parse string to date with either std::get_time or strftime

问题

代码部分不翻译,以下是您提供的内容的翻译:

当我尝试使用std::get_timestrftime将字符串解析为日期时,在我的树莓派上会收到SIGABRT错误。但是当我在我的Ubuntu电脑上执行相同的代码时,它正常工作。

std::get_time示例:

#include <chrono>
#include <iomanip>
#include <iostream>

int main() {
    std::stringstream stream;
    stream.str("09:35:44,02-23-2023");
    std::tm tm{};
    const std::string format = "%H:%M:%S,%m-%d-%Y";
    if((stream >> std::get_time(&tm, format.c_str())).fail()) {
        std::cout << "解析失败" << std::endl;
    }
    std::cout << std::chrono::seconds(std::mktime(&tm)).count() << std::endl;
}

我尝试在Buster和Bulleseye上的树莓派上执行代码,但都无法正常运行。而我的运行Ubuntu 22.04的计算机可以正常执行示例代码。我尝试查找在ARM架构上解析日期时的已知问题,但没有找到任何信息。

非常感谢任何帮助!

编辑: 我使用CLion的gcc工具链来编译程序,由cmake文件管理。我在两台树莓派上都尝试了远程编译(都是3b型号,一个运行Buster,一个运行Bulleseye),选择了来自bin目录的默认gcc和g++编译器(在Buster上是gcc-8.3.0,cmake 3.16,Bulleseye上是gcc-10.2.1,cmake 3.18.3)。我还尝试在Ubuntu上进行交叉编译(使用Ubuntu的arm-linux-gnueabihf-gcc/g++编译器),但如果我记得正确,那会出现不同的问题。我在CLion中使用远程gdb调试程序在树莓派上执行,而SIGABRT错误发生在调用std::get_time期间。我甚至可以看到,检查tm时,它包含正确的小时、分钟和秒,但然后似乎停止了。

再次感谢所有在这里发表评论和回答的人!

编辑2: 我将尽快尝试在全新设置的树莓派上编译和执行程序,只在树莓派上使用命令行,以排除与CLion工具链相关的任何问题。

编辑3: 再次感谢所有在这里提供意见的人。不幸的是,最不令人满意的解决方案起作用了。我今天再次尝试,但我无法再次复制错误,现在它可以正常工作。我只是无法弄清楚上周我做错了什么...对于给大家带来麻烦,我感到抱歉!

英文:

When I'm parsing a string to date with either std::get_time or strftime I receive a SIGABRT on my RaspberryPi. When I execute the same code on my Ubuntu computer it works fine.

std::get_time example:

#include &lt;chrono&gt;
#include &lt;iomanip&gt;
#include &lt;iostream&gt;

int main() {
    std::stringstream stream;
    stream.str(&quot;09:35:44,02-23-2023&quot;);
    std::tm tm{};
    const std::string format = &quot;%H:%M:%S,%m-%d-%Y&quot;;
    if((stream &gt;&gt; std::get_time(&amp;tm, format.c_str())).fail()) {
        std::cout &lt;&lt; &quot;Parsing failed&quot; &lt;&lt; std::endl;
    }
    std::cout &lt;&lt; std::chrono::seconds(std::mktime(&amp;tm)).count() &lt;&lt; std::endl;
}

I tried Raspberrys with Buster and Bulleseye and both fail to execute the code.
My computer running Ubuntu 22.04 executes the example just fine.
I tried to find known issues when parsing dates on arm architecture, but did not find any.

Any help is greatly appreciated!

Edit:
I'm using CLion gcc-Toolchains to compile the program, managed by a cmake file.
I used remote compilation on either of the Raspberrys (both 3b, with either buster or bulleseye), selecting the default gcc and g++ compiler from the bin directory (on buster gcc-8.3.0, cmake 3.16 and bulleseye gcc-10.2.1, cmake 3.18.3). I also tried to crosscompile it on Ubuntu (with Ubuntus arm-linux-gnueabihf-gcc/g++ compilers), but that had different issues if I recall correctly.
I debugged the program in CLion with remote gdb executing it on the raspberry and the SIGABRT happens during the call to std::get_time. I can even see, inspecting tm, that it contains hour, minutes and seconds correctly, but then it seems to stop.

Thanks to everyone commenting and answering so far!

Edit2: I will try to compile and execute the program on a freshly setup Raspberry asap, command line only on the raspberry to rule out any issues with the CLion toolchain.

Edit3: Thanks again for everyone giving input here. Unfortunately the most unsatisfying solution worked. I tried it again today and I just cannot reproduce the error, but it is working now. I just can't figure out what I did wrong last week... Sorry for the hassle!

As suggested in the comments, you would need to give the same level of details on the exact combination of hardware/operating system/c++ compiler you are using, so that others may attempt reproducing the issue you experimented.

我终于弄清楚了我做错了什么。
首先,我需要向所有查看我的示例的人道歉,因为这个示例完全正常工作。
我的问题是由于这个错误 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=45896 导致的,这个错误在Ubuntu 22.04中已修复,但在Raspbian 11中没有修复。
现在我要么在解析之前修改字符串,要么寻找获取日期的不同方法,尽管第一种选项对我来说更有希望。
感谢大家帮助我!

英文:

I finally could figure out what I was doing wrong.
First of all I need to apologize to everyone looking at my example, because this is working absolutely fine.
My issue is occurring due to this bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=45896 which is fixed in Ubuntu 22.04 but not Raspbian 11.
I will now either modify the string before parsing or look for a different way to get the date, although the first option seems more promising to me.
Thank you all for helping me with this!
