Segmentation error of C ++ main program

Question

here is my CPP program

#include <iostream> int main(int argc, char *argv[]){ return 0; } 

compiling and executing this causes a seg error:

 [18:08 ~] > g++ test.cpp [18:09 ~] > ./a.out Segmentation fault 

Does anyone have any ideas on this issue? Many thanks for your help.

Here are some details that may be helpful:

Thanks.

Answer 1

Apparently your problem is that your g ++ installation is broken. I see from the posts that you have RHEL6, but somehow has version 3.4.6 of libstdc ++.

My RHEL6 system has version 4.4.6 gcc, libstdc ++, etc. I assume that this old version of libstdc ++ is related to your problem.

In which versions did you install gcc, g ++, and libstdc ++? From other posts, it looks like you have 4.4.7, but do you have multiple versions or mixed versions?

 rpm -q gcc g++ libstdc++ 

Also, what other directories do you have in / usr / lib / gcc / x 86_64-redhat-linux?

 ls /usr/lib/gcc/x86_64-redhat-linux 

Answer 2

I think you missed something when installing g ++

 Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.107.el6.x86_64 libgcc-4.4.7-3.el6.x86_64
