我最近使用sudo apt-get install gcc-arm-none-eabi在Ubuntu 18.10（Cosmic Cuttlefish）上安装了ARM GCC工具链，并试图运行arm-none-eabi-gdb。
[每当我尝试运行它时，都会出现以下错误：
arm-none-eabi-gdb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory
我尝试使用sudo apt-get install libncurses5-dev libncursesw5-dev安装libncurses-成功安装了库，但是仍然存在相同的问题。
我还检查以确保文件为64位：arm-none-eabi-gdb: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.24, BuildID[sha1]=340c78388950836989ecda5c89474e1bf7b03820, stripped
我可以从这里尝试什么？
我从here安装了Ubuntu 18.10桌面（Cosmic Cuttlefish），但无法安装gcc-arm-none-eabi：
ubuntu@ubuntu:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.10
Release: 18.10
Codename: cosmic
ubuntu@ubuntu:~$ sudo apt-get install gcc-arm-none-eabi
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package gcc-arm-none-eabi
然后我安装了libncurses5-dev和gcc-linaro-7.3.1-2018.05-x86_64_arm，并得到了与您相同的.so相关错误。
由于我在16.04和18.04中都没有这个问题，所以建议您从源代码编译最新的GDB，以避免在Ubuntu 18.10中出现程序包/动态链接库不匹配的问题：
sudo apt-get install build-essential libncurses5-dev libexpat1-dev texinfo-doc-nonfree
pushd /tmp
wget -qO- ftp://ftp.gnu.org/gnu/gdb/gdb-8.2.tar.xz | tar Jxv
mkdir gdb
cd gdb
../gdb-8.2/configure --enable-tui --with-expat --prefix=/usr/local --target=arm-eabi --program-prefix=arm-eabi-
make all
sudo make install
popd
即使我安装了texinfo-doc-nonfree，由于缺少makeinfo，安装将失败，但是将安装二进制文件：
ls /usr/local/bin
arm-eabi-gdb arm-eabi-gdb-add-index arm-eabi-run
并且arm-eabi-gdb这次将正常启动：
arm-eabi-gdb --version

arm-eabi-gdb -tui也可以工作-我鼓励您使用TUI模式。您应该像我一样喜欢它-我想。
