我需要yum命令,它可以验证linux机器中所有repo的螺旋检查。
我尝试过yum,但退出代码仍然是0(尽管我们有错误)。

我最近下载了链接中提到的代码。我的GCC版本是4.1.2。在console中开始出现以下错误之前,编译过程至少进行了一个小时。
LLVM支持声明我需要使用gcc44-c++,这在我们的机器中是不可用的:
Red Hat Enterprise Linux Server release 5.5 (Tikanga)
# yum install gcc44-c++

我尝试用"g++ -std=c++11 -o w w.cpp“编译下面的程序,得到错误”cc1plus: error: unrecognized command line option "-std=c++11“”。已尝试使用g++ -Dstd=c++11 -o w w.cpp进行编译,并获得以下错误集:
In file included from /usr/lib/gcc/i686-redhat-linux/4.4.7/../../../../include/c++/4.4.7/iosfwd:41,

我目前正在努力连接一个简单的库。
我从这里编译并成功安装了G729实现,如下所示:
cmake . -DCMAKE_INSTALL_PREFIX=/usr
make
make install
当我检查符号是否存在时,它们是否存在:
nm /usr/lib64/libbcg729.so | less
....

我按照github中的这些说明克隆并构建了boost库。
./b2命令的末尾告诉我
Boost C++库已成功构建!
The following directory should be added to compiler include paths:
/home/user/Desktop/boost
The following directory should be added to linker library paths:
/home/user/Desktop/boost/stage/lib
我应该如何处理这些文件夹?我想把boost放在“为了让gcc看到它而应该去
我想在我的机器上卸载tmux。我的tmux版本是:
tmux next-3.4
which tmux给了我:

No match for argument: tmux
No packages marked for removal.

Nothing to do.

我正在RedHat Linux 8.5上开发一个Bash脚本。
我想要创建一个脚本,它将处理一个目录,分析子文件夹,并创建一个构建的脚本。
这是一个痛苦的过程,因为到目前为止,我还没有编写bash脚本的经验:

cd ~/work-mmcm2
ls -d * >../dirs.txt
pass=1
while read p; do
if [$pass -eq 1]; then
cd $p

我收到了这组gcc的错误,我似乎无法从谷歌或手册页面中得到答案。对于这意味着什么或者从哪里开始寻找,有什么见解吗?

# Grand finally link all the object files into one

我正在Linux上用C++开发一个程序。gcc的版本是4.5.1 20100924。我想在我的程序中使用std::atomic_int。我已经包含了原子头,如下所示:
