问题[gcc](ubuntu)

该文件包含编译器在运行 configure 时产生的任何消息，以在 configure 出错时帮助调试。

它是由 liberasurecode configure 创建的，由 GNU Autoconf 2.71 生成。调用命令行是

我没有一些 c11 字符串函数的手册页，例如strcpy_s和strncpy_s。我有最新的版本gcc，但不知何故它无法识别gcc -std=c11 -D_DEFAULT_SOURCE -Wall -Werror -pedantic之前#define __STDC_WANT_LIB_EXT1__ 1的版本#include <string.h>。我想阅读手册页以找出原因。

我已经完成了sudo apt-get updatefollowed by sudo apt-get install glibc-doc。到目前为止，我还安装了manpages-dev，，manpages-posix-dev有什么想法吗？我也想知道，如果我想安装 X 的手册页，我怎么知道要安装什么？有我们可以使用的手册页搜索功能吗？

我在用着：

Linux ip-172-31-28-209 5.4.0-1059-aws #62~18.04.1-Ubuntu SMP Fri Oct 22 21:51:38 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

我在运行程序时遇到错误：

while loading shared libraries: libg2c.so.0: wrong ELF class: ELFCLASS32

我该如何解决？

我看了这篇文章，但它是针对 32 位版本的 Ubuntu 的。

我在 WSL 中运行 Ubuntu 18.04，我用它来编译我的 c++ 程序。

我需要编写一个程序来获取某个目录中所有文件的名称并将它们添加到字符串向量中。浏览互联网我发现我可以使用“文件系统”库以简单易行的方式完成此操作。

问题是，每当我尝试使用这个答案时，我都会收到错误消息'filesystem' has not been declared。我怀疑发生这种情况是因为我可能没有安装文件系统库。

我已经找到了一种通过使用实验功能并在编译命令中添加标志来修复它的方法，但我仍然想知道是否有某种方法可以将我的 gcc 包更新为已经安装了库的包。

我当前的 gcc 版本是 7.5.0。

有没有办法我可以做到这一点？

使用./bootstrap命令安装时出现此错误cmake

Error when bootstrapping CMake:
Cannot find appropriate C compiler on this system.

我检查了 gcc 并得到了

gcc --version

whereis gcc

我检查了 cmake_bootstrap.log文件并得到了

我正在尝试aarch64-linux-gnu-gcc为 Raspberry Pi 3 64 位构建一个 C++ 文件，并且正在运行以下命令：

但我收到此错误：

我正在尝试在 ubuntu 18.04LTS 上安装 systemc-2.3.3。以前我尝试使用 20LTS，但由于某种原因无法正常工作。我遵循以下说明：安装 SystemC-2.3.3。我是新手，从不在ubuntu上安装任何软件。当我输入命令时，我收到以下错误：

我无法理解我的配置文件。配置文件的链接是：配置文件 请帮助。

我目前使用的是 Ubuntu 18.04，我需要 MATLAB 的 gcc 4.8。所以我尝试使用安装 gcc-4.8

$ sudo apt-get install gcc-4.8
E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/l/linux/linux-libc-dev_4.15.0-117.118_amd64.deb  404  Not Found [IP: 2403:8940:3:1::f 80]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

所以我运行了命令

sudo apt-get update 

我没有显示任何错误，但运行 gcc version 命令给出了这个

$ gcc -v
Command 'gcc' not found, but can be installed with:
sudo apt install gcc

以前我曾经有 7.5，但现在没有了。

我正在尝试安装 arm 工具链，我的编程老师给了我如何安装的说明。我提取了下载的库，/opt并尝试创建/usr/local/bin指向的链接/opt/gcc.../bin/*file

他给我的命令：

sudo ln -s opt/gcc-arm-none-eabi-9-2019-q4-major/bin/arm-none-eabi-gcc /usr/local/bin/arm-none-eabi-gcc

然后我检查了版本：

arm-none-eabi-gcc --version

但它说它没有安装。我/usr/local/bin 和午夜指挥官一起调查，链接是红色的：!arm-none-eabi-gcc

我检查了，我写的一切都正确。我在想也许我从 arm 网站下载了错误版本的工具链。

有人能帮我吗？谢谢！

我正在尝试在 Ubuntu20.04 上构建 GCC6.3.0，但似乎无法理解/修复错误。

我下载了 tar 文件（从多个镜像中尝试过，总是相同的错误），解压它，在这个解压目录中运行

./contrib/download_prerequisites

它下载并创建所需的快捷方式。然后我离开这个目录，创建一个新目录“gccbuild”，在这个目录中，我运行

$PWD/../gcc-6.3.0/configure --prefix=$HOME/GCC-6.3.0 --enable-languages=c,c++,fortran,go

如果需要，我可以添加完整的输出，很多没有，但我不认为这是问题所在。最后几行输出：

checking where to find the target windmc... host tool
checking whether to enable maintainer-specific portions of Makefiles... no
configure: creating ./config.status
config.status: creating Makefile

然后，我运行 make，以下是输出的最后几行：
