无法用64位g ++编译32位

Question

我正在使用代码块.我正在使用ubuntu.这是编译的输出.

g++ -Wall  -O2  -m32 -nostdlib    -Iinclude  -c /home/miroslav/Development/WEBGINE/src/WEBGINE/Component.cpp -o obj/ReleaseCGI32/src/WEBGINE/Component.o

关于32位库的一点信息:

miroslav@miroslav-desktop:/usr/lib32$ ls -la libst*
lrwxrwxrwx 1 root root     19 2010-06-21 20:50 libstdc++.so.6 -> libstdc++.so.6.0.13
-rw-r--r-- 1 root root 975088 2010-03-27 01:16 libstdc++.so.6.0.13

Answer 1

一定要安装gcc-multilib和g++-multilib.这些依赖于64作为32位gcc和stdc ++库.
