이 안내서에서는 distcc에서의 다른 프로세서 아키텍처간 크로스컴파일 설정 방법을 보여줍니다.

도입부
는 네트워크에 연결한 다양한 컴퓨터에게 덩치가 큰 프로그램을 컴파일하도록 일감을 공유하는 도구입니다. 같은 프로세서 아키텍처로 만들어진 같은 툴체인을 네트워크에 연결한 여러대의 머신이 사용하면 설정을 따로 할 필요가 없습니다.

This guide provides instructions on how to configure distcc to compile for different architectures.

필요한 유틸리티 이머지
First, you will need to emerge on all the machines that will be involved in the compiling process. is a tool that makes building cross-architecture toolchains easy. Its usage is straightforward: will build a full cross-toolchain targeting the Sparc architecture. This includes binutils, gcc, glibc, and linux-headers.

You will need to emerge the proper cross-toolchain on all the helper boxes. If you need more help, try running.

크로스 툴체인을 최상의 상태로 만들려면 도우미 머신에 빌드할 정확한 버전의 크로스 개발 꾸러미를 만들 스크립트를 마련했습니다(스크립트는 대상 머신에서 실행합니다).

Next, you will need to emerge on all the machines that will be involved in the process. This includes the box that will run emerge and the boxes with the cross-compilers. Please see the Gentoo Distcc Documentation for more information on setting up and using.

인텔 x86 하위 아키텍처
If you are cross-compiling between different subarchitectures for Intel (e.g. i586 and i686), you must still build a full cross-toolchain for the desired CHOST, or else the compilation will fail. This is because i586 and i686 are actually different CHOSTs, despite the fact that they are both considered "x86." Please keep this in mind when you build your cross-toolchains. For example, if the target box is i586, this means that you must build i586 cross-toolchains on your i686 helper boxes.

Using might fail with one of the following errors:

올바르게 크로스컴파일 하도록 distcc 설정
In the default distcc setup, cross-compiling will not work properly. The problem is that many builds just call instead of the full compiler name (e.g. ). When this compile gets distributed to a distcc helper box, the native compiler gets called instead of your shiny new cross-compiler.

Fortunately, there is a workaround for this little problem. All it takes is a wrapper script and a few symlinks on the box that will be running. We'll use a Sparc box as an example. Wherever you see  below, you will want to insert your own CHOST value (  for an AMD64 box, for example). When you first emerge distcc, the directory looks like this:

여러분이 실행할 명령입니다:

Next, we'll create the new script on this box. Fire up your favorite editor and create a file with the following text in it, then save it as. Remember to change the CHOST value (in this case, ) to the actual CHOST of the box that will be running the emerge.

끝났다면 은 다음과 같은 모양새를 띱니다:

다음 심볼릭 링크를 중복적용할 distcc 꾸러미를 업그레이드 하고 나서도 래퍼를 계속 존재하게 내버려 둘 지 확인하려 할 것입니다. 다음처럼 파일을 편집하면 원하는대로 할 수 있습니다:

Then create this file:

Give it the proper permissions:

축하합니다. 이제 (원하는 대로) 동작하도록 cross-distcc를 설정했습니다.

동작 원리
When is called, it checks to see what it was called as (e.g. ,  , etc.) When distcc then distributes the compile to a helper box, it passes along the name it was called as. The distcc daemon on the other helper box then looks for a binary with that same name. If it sees just, it will look for , which is likely to be the native compiler on the helper box, if it is not the same architecture as the box running. When the full name of the compiler is sent (e.g. ), there is no confusion.

Troubleshooting
This section covers a number of common problems when using for cross-compiling.

Remote host distccd COMPILE ERRORS
When receiving the message  within a remote host's  file, see the above notes concerning specifying the correct architecture name (ie. ).

Another solution is to uninstall and re-install compiler tools, using the  option, or ensuring  no longer exists, and then completely reinstall the cross compiler.

It might also be wise to edit the remote host's, and ensure the contents of the CFLAGS variable are similar on all computers or hosts performing compiler operations.

Failed to exec $TARGET-uknown-linux-gnu-gcc: No such file or directory
The wrapper scripts might fail to execute, even with correct permissions:

To resolve this, make sure to have the wrapper script created with the complete name of the architecture target:
