Hi, lan
That's right.
g++ search .so in the /usr/local/lib64, instead of ..../gcc-4.3.3/lib64 ,
So I soft link all the .so in the /usr/local/lib64 TO ..../gcc-4.3.3/lib64 ,
and "g++ -o hello hello.cpp" works right now.
What an awkward method!
I have to soft link /usr/local/lib64/*.so back again if I wanna use
another gcc version!
Do u have another better solution to tell gcc search to search
"..../gcc-4.3.3/lib64" directory by a global setting,
not by "-L" option??
