我按照 GCC 安装说明 [1] 下载源代码并配置我的构建，但是当我尝试make从顶层目录（使用MAINTAINERS和Makefile.in）时，我总是收到相同的错误：make: *** No targets specified and no makefile found.我不知道如何继续安装指南的构建步骤。

编辑：我注意到我的objdir/config.log文件以结尾configure: exit 1，我不确定这是否是预期的，或者是否表示配置失败并且项目不处于可行构建状态。

我试过了

  • make

  • make install

  • make bootstrap

  • make -f Makefile.in

    Makefile:26: *** missing separator. Stop.由于以 和 开头的行，@if此操作失败并显示消息@endif。此自动生成的文件有很多这样的行，我怀疑我是否应该手动删除它们。

到目前为止我的完整工作流程：

# Get the source
~$ mkdir gcc; cd gcc
~/gcc$ git clone git://gcc.gnu.org/git/gcc.git .

# Make objdir/ and configure my desired build
~$ mkdir ARM; cd ARM
~/gcc/ARM$ ../configure --prefix=$HOME --target=aarch64-none-elf

# Try to "just make"
~/gcc/ARM$ cd ..
~/gcc$ make # :(

我想使用带有 ARA 的 mysql 引擎/数据库，而不是工具附带的默认 sqlite 引擎，以便为多个条目提供更强大的引擎，但我面临的问题不允许我在下面实现这一点细节 ：

当我在我的 ARA 服务器的 settings.yml 文件中指定 mysql 引擎时，出现以下错误：

~/.ara/server # [ara] Using settings file: /root/.ara/server/settings.yaml
Traceback (most recent call last):
  File "/root/.local/lib/python3.8/site-packages/ara/server/__main__.py", line 54, in main
    import MySQLdb  # noqa
ModuleNotFoundError: No module named 'MySQLdb'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/root/.local/bin/ara-manage", line 8, in <module>
    sys.exit(main())
  File "/root/.local/lib/python3.8/site-packages/ara/server/__main__.py", line 56, in main
    raise MissingMysqlclientException from e
ara.setup.exceptions.MissingMysqlclientException: The mysqlclient python library must be installed in order to use the MySQL database engine.

所以我检查了是否安装了 mysqlclient 并且显然没有安装：

~/.ara/server # pip3 list installed | grep mysql

但是当我尝试安装它时，我有这个巨大的异常块：


~/.ara/server # pip3.8 install mysqlclient

如果我理解错误，则由于缺少 gcc 存在编译问题。但是当我尝试使用 pip 卸载 gcc7 时它不起作用：

~/.ara/server # pip3 install gcc7
ERROR: Could not find a version that satisfies the requirement gcc7
ERROR: No matching distribution found for gcc7

1-我的分析对吗？

2-这背后的真正问题是什么？我的意思是还有其他可能导致此问题的依赖项。任何帮助或提示将不胜感激。

PS：我正在研究高山分布。

我在 Debian Wheezy 主机上的 Debian Lenny chroot 中构建了 gcc-4.9.0。拱门 = Armel（Wheezy 和 Lenny）。我使用了以下配置选项：

$PWD/../gcc-4.9.0/configure --prefix=/usr/local/GCC-4.9.0 --enable-languages=c,c++ --with-arch=armv4t --with-float=soft --enable-checking=release --enable-shared --build=arm-linux-gnueabi --host=arm-linux-gnueabi --target=arm-linux-gnueabi LDFLAGS=-Wl,-no-keep-memory --disable-libjava

当我尝试构建一些库（本例中为 libgcrypt）时，我无法构建共享库：

checking whether the /usr/local/GCC-4.9.0/bin/gcc linker (/usr/local/GCC-4.9.0/bin/gcc) supports shared libraries... no
checking dynamic linker characteristics... GNU/Linux ld.so
checking how to hardcode library paths into programs... unsupported
checking whether stripping libraries is possible... yes
checking if libtool supports shared libraries... no
checking whether to build shared libraries... no
checking whether to build static libraries... yes`

对于卷曲：

gcc: error: ../lib/.libs/libcurl.so: No such file or directory
make[2]: *** [Makefile:923: curl] Error 1

构建 gcc 时我是否仍然缺少一些配置选项？

我想使用https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html上列出的一些警告标志。然而，我似乎不能全部使用它们。例如-Wpessimizing-move，gcc 无法识别我（总是生成错误，因为此选项不存在）。很多标志都存在这个问题。我使用 fedora 存储库中的 gcc 这就是我的版本输出：

我正在学习关于 lex 和 yacc 的教程，该教程要求我编译一些 C 源代码。本教程要求我在终端中输入以下行：

$ gcc ‑o exampleA lex.yy.c ‑lfl

但我随后收到消息：

bash: $: command not found...

我尝试使用更简单的 HelloWorld C 源代码文件，但得到了相同的消息。

但我知道 gcc 可执行文件位于 /usr/bin 中，当我在终端中键入“gcc --version”或“gcc --help”时，我会得到一个合理的响应。

这里发生了什么？

顺便说一句，我正在使用 Fedora 29 Linux 发行版。
