在 Eclipse SIGSEV 中编译的 C 二进制文件

Question

我一直在尝试让一个工作程序通过 Eclipse 运行(以便于调试)，但我似乎无法完成它。

我有一个简单的命令可以通过终端编译程序:

gcc -m32 *.c -lm

然后我可以正确地执行 ./a.out。

为了在 Eclipse 中使用用户友好的 gdb 插件，我也想在 Eclipse 中编译和运行它。

到目前为止，我已将 -lm -m32 -w 添加到“Cross GCC Compiler”下项目设置中的“Miscellaneous”字段以及“Cross GCC Compiler”下的“Miscellaneous”字段中GCC 链接器”。

该程序似乎可以正常编译(见下文)。但是，当我选择 libslip 二进制文件并尝试执行它时，它立即崩溃了。

当我通过终端运行 libslip 可执行文件时，我得到以下输出:

Debug$ ./libslip 
Killed

当我通过 Eclipse 运行它时，我得到了这个:

<terminated> libslip [C/C++ Application] <path>

gdb libslip 输出如下:

Reading symbols from libslip...done.
(gdb) b 1
Breakpoint 1 at 0xb4d3: file ../SlipTest.c, line 1.

Answer 1

我终于找到了!答案是不要手动添加 -lm，而是将其添加到库中。

让它工作的方法是:

右键单击“项目”>“属性”>“C/C++ 构建”>“设置”>“GCC C 链接器”>“库”> 添加“m”。

这使得它可以完美地编译和运行! :)
