Question

I have a problem, i’m compiling my C++ app in Linux machine. Then i move executable to other machine, but i have an error:

./server: /lib64/libc.so.6: version `GLIBC_2.7' not found (required by ./server)

How can i fix it? Without recompiling on second machine where this error happens (it is my client machine)

Compile command:

g++  -o server  test.cpp server.cpp ... -lboost_system -lboost_thread -std=c++0x 

Thanks!

Answer 1

Your app is using glibc-2.7 library, and app can not find it on other machine. It probably have older version of this library. You have following options:

• Upgrade this library on target host
• Link you app against older library version
• Use static linking
• Ship library together with app

How statically link to just one library:

gcc main.c mylibrary.a -o main

Note that most distros do not install static libraries by default.
