[英]Can't run 32 bit binary on 64 bit Debian
I'm compiling C++ on Debian Linux (64 bit) and need to be able to compile to 32 bit for another system. 我正在Debian Linux(64位)上编译C ++,并且需要能够为另一个系统编译为32位。 The binaries won't run on my 64 bit system and having them run there would be far more convenient for testing.
二进制文件不能在我的64位系统上运行,让它们在那里运行会更方便测试。
My C++ for testing this is int main () { std::cout << "This is Main.cpp" << std::endl; }
我测试它的C ++是
int main () { std::cout << "This is Main.cpp" << std::endl; }
int main () { std::cout << "This is Main.cpp" << std::endl; }
with iostream included, so nothing fancy there. int main () { std::cout << "This is Main.cpp" << std::endl; }
用的iostream包括在内,所以没有什么花哨那里。
My compile line is g++ -m32 Main.cpp
我的编译行是
g++ -m32 Main.cpp
When I do ./a.out
I get -bash: ./a.out: cannot execute binary file: Exec format error
当我这样做
./a.out
我得到-bash: ./a.out: cannot execute binary file: Exec format error
I have done quite a bit of searching trying to resolve this and have apt installed: libc6:i386, libncurses5:i386, and libstdc++6:i386. 我已经做了很多搜索试图解决这个并安装了apt:libc6:i386,libncurses5:i386和libstdc ++ 6:i386。
Any other ideas to fix this would be much appreciated. 任何其他想法来解决这个问题将非常感激。
You need to install 32bit libraries, eg 您需要安装32位库,例如
dpkg --add-architecture i386
apt-get update
apt-get install libc6-i386
You can find out which libraries are needed using the ldd command. 您可以使用ldd命令找出所需的库。 You can use apt-file to find the packages for the libraries.
您可以使用apt-file查找库的包。
