【问题背景】

在openEuler上移植cisTEM软件后，发现运行出现了coredump，详细信息如下

【问题分析】

1、修改Makefile中的编译选项

（1）、在修改了/path/to/cisTEM/cistem-1.0.0-beta/目录下的Makefile，修改如下：

CPPFLAGS =  -DNDEBUG -funroll-loops –O0 -Wall -pipe -fexpensive-optimizations -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -g

CXXFLAGS =  -DNDEBUG -funroll-loops –O0 -Wall -pipe -fexpensive-optimizations -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE –g

（2）、重新make之后分析core文件gdb调试信息如下：

warning: File "/usr/lib64/libthread_db-1.0.so" auto-loading has been declined by your `auto-load safe-path' set to "$debugdir:$datadir/auto-load".

To enable execution of this file add

        add-auto-load-safe-path /usr/lib64/libthread_db-1.0.so

line to your configuration file "/root/.gdbinit".

To completely disable this security protection add

        set auto-load safe-path /

line to your configuration file "/root/.gdbinit".

For more information about this security protection see the

"Auto-loading safe path" section in the GDB manual.  E.g., run from the shell:

        info "(gdb)Auto-loading safe path"

warning: Unable to find libthread_db matching inferior's thread library, thread debugging will not be available.

warning: File "/usr/lib64/libthread_db-1.0.so" auto-loading has been declined by your `auto-load safe-path' set to "$debugdir:$datadir/auto-load".

warning: Unable to find libthread_db matching inferior's thread library, thread debugging will not be available.

（3）、从上面的gdb调试信息来看，仍然无法定位到具体core掉的代码详细信息

2、进一步修改src目录下的makefile文件

（1）、通过分析发现在src中还有一个makefile文件并未修改，/home/yylu/cisTEM/cistem-1.0.0-beta/src，修改如下标黄部分：

CPPFLAGS =  -DNDEBUG -funroll-loops -O0 -Wall -pipe -fexpensive-optimizations -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -g

CXXFLAGS =  -DNDEBUG -funroll-loops –O0 -Wall -pipe -fexpensive-optimizations -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE –g

（2）、重新make clean之后make，并执行make install，注意此时不要执行./configure -prefix=/path/to/cistem，会重新生成makefile文件

（3）、重新运行后出现coredump，分析core信息如下

#0  0x0000000000538428 in MovieGroupPickerComboPanel::FillComboBox(bool) (this=0x328fd670, include_all_movies_group=true) at gui/../core/../gui/AssetPickerComboPanel.h:73

#6  0x000000000043e784 in main(int, char**) (argc=1, argv=0xfffffc948928) at programs/projectx/projectx.cpp:14

【问题根因】

1、进一步分析代码：

通过进一步分析代码，发现AssetPickerComboPanel.h文件中函数没有return，进一步排查发现该文件中其他函数均没有返回值

2、修改代码重新编译后可以运行该程序：

3、关闭窗口出现coredump：

当用鼠标关闭该窗口时，会出现coredump信息，进一步分析是因为projectx.cpp文件中OnExit()函数没有返回值，按照如下黄色部分修改后问题解决；

int MyGuiApp::OnExit()

{

         delete cistem_config;

/*     main_frame->Destroy();

         overview_panel->Destroy();

         actions_panel->Destroy();

         assets_panel->Destroy();

         settings_panel->Destroy();

         // Individual Panels

         movie_asset_panel->Destroy();

         image_asset_panel->Destroy();

         align_movies_panel->Destroy();

         run_profiles_panel->Destroy();*/

    return true;

}

【修改方案】

修改AssetPickerComboPanel.h、projectx.cpp文件中代码，将需要有返回值的加上return，重新编译

【END】
