我现在开始调试过程。 1.我启动了一个模拟器 2.我在eclipse中调试应用程序。 3.我确保我在hello-jni目录中 4.我输入ndk-gdb --verbose
我已经查看了有关该主题的其他帖子,ndk-gdb输出似乎总是看起来像以下内容
warning: shared library handler failed to enable breakpoint
0xafd0c51c in epoll_wait () from /home/zayac/code/android-ndk-r5/samples/hello-jni2/obj/local/armeabi/libc.so
似乎已准备好使用“epoll_wait()...”文本。
当我运行ndk-gdb --verbose时,我从未看到该文本。我只是得到了waring和(gdb)提示符。这是输出......

(gdb)
当我输入像 list 这样的gdb命令时,我得到了
(gdb)未加载符号表。使用“file”命令。
任何帮助都会很棒!
答案 0 :(得分:3)
我遇到了同样的问题,因为libs / armeabi / gdb.setup包含CR(CRLF)字符。 在开发主机(项目目录)上删除它之后,它无需重新安装。
gdb.setup似乎是由ndk-build编写的,它似乎在Windows上引入了CR字符(而不是在Linux上)。
