Question

我刚从运行linux的服务器上的主目录中的源代码编译gdb 7.8。我以前一直在使用gdb 7.6，除了gdb本身的稳定性问题（升级的原因），一切正常。

自gdb升级以来，当我运行cgdb 0.6.7时，我立即收到以下消息：

Python Exception <type 'exceptions.ImportError'> No module named gdb:

warning:
Could not load the Python gdb module from `/home/username/bin/gdb//python'.
Limited Python support is available from the _gdb module.
Suggest passing --data-directory=/path/to/gdb/data-directory.

当我构建gdb时，我使用了./configure --with-python。

当我运行cgdb并且我的程序达到段错误时，我输入backtrace并收到以下消息：

Python异常没有名为gdb.frames的模块：

因此，如果没有python支持，我似乎无法使用gdb / cgdb。我该怎么做才能解决这个问题？

FWIW;我不会使用python，我通常会写c++。

Answer 1

您应指定“--data-directory”的值。例如，如果从构建目录加载gdb，则命令应为：

./gdb -data-directory ./data-directory

然后gdb可以知道在哪里找到python模块。

您可以参考此discussion。

Answer 2

root@labs:~/gdb-8.1# gdb --version
Python Exception <type 'exceptions.ImportError'> No module named gdb: 
gdb: warning: 
Could not load the Python gdb module from `/usr/local/share/gdb/python'.
Limited Python support is available from the _gdb module.
Suggest passing --data-directory=/path/to/gdb/data-directory.
....

尝试将cp python lib添加到--data-directory = /path/to/gdb/data-directory 。我的数据目录是 / usr / local / share / gdb / python ，

# mkdir -p /usr/local/share/gdb/python/gdb
# cp -rf ~/gdb-8.1/gdb/python/lib/gdb/* /usr/local/share/gdb/python/gdb/


# gdb --version

Answer 3

只是为了完成上述回复：

您可能已将可执行文件 gdb 复制到/usr/local/bin（这是我优先考虑我作为默认shell gdb 安装的最新gdb的方法，同时防止弄乱默认的Ubuntu的 gdb ）。然后，您应该考虑必须将数据目录参数从原始位置提供给您在/usr/local/bin中复制的参数。那就是：

/usr/local/bin/gdb --data-directory=/path_to_fully_installed_gdb_folder/data-directory

PS：我在 Ubuntu 16.04

上为 gdb-8.1 做了这个

我刚遇到这个问题，想分享我的发现。在编译过程中，特别是在“ make install”步骤中，我注意到一条消息：

[BrowserStack] Starting upload process. [BrowserStack] Uploading app app/build/outputs/apk/flavorProduction/debug/browserstack-sample-debug.apk to Browserstack. [BrowserStack] [ERROR] File not found at app/build/outputs/apk/flavorProduction/debug/browserstack-sample-debug.apk [BrowserStack] ERROR : App Id empty. ABORTING!!!

我没有makeinfo听起来没问题，但实际上这导致了OP询问的错误。安装WARNING: `makeinfo' is missing on your system. You should only need it if you modified a `.texi' or `.texinfo' file, or any other file indirectly affecting the aspect of the manual. The spurious call might also be the consequence of using a buggy `make' (AIX, DU, IRIX). You might want to install the `Texinfo' package or the `GNU make' package. Grab either from any GNU archive site.后，我重新安装了texinfo并在没有python错误消息的情况下运行了gdb。

python异常<type'exception.importerror'=“”>没有名为gdb的模块：</type>
