Hi ,

I hv compiler my program with gnu g++ 2.95.2. Then, I hv transfer my binary to a site that only hv g++ 2.7. Is this possible for me to run my program at that site? or I need to install g++ 2.95.2 in that site too.

I hv tried run my program and it failed coz cannot found one of a g++ 2.95.2 library.

I'm not sure this is my environment setting problem or i need to install the g++ 2.95.2.

thanks,
huey ling

Did you recompile on the new box, or did you just copy the binary over? If you didn't recompile on the other box, recompile over there and then try to run it.

Does the other site have the same OS?
What OS is the Target site, and what is the version of the OS?
You need to make sure that both the OS and the version match.  If they match, you should be able to run your binaray on the target machine.

You can link your program with libstdc++ in static linkage
this way you will have no problem porting from version to version of g++.
You must however make sure it is running on the same OS
(like Axter mentioned above)
In order to link your program in static linkage add
 
        -lstdc++

to your makefile linking line for example

 g++ -o Test -lstdc++ X.o Y.o z.cpp

if you are using more libraries you should compile them static too.

I hope this works

sorry ... I forgot -static

use -static  -lstdc++ in your make file line
 for example :
   g++ -o Test -static -lstdc++ X.o Y.o z.cpp

Again me ... :)

You can also try

     -static-libgcc  
for example :
   g++ -o Test -static-libgcc X.o Y.o z.cpp


for more information  you can look in gcc man pages
