 Posted: Fri Oct 25, 2024 3:45 pm Post subject: Trying to get distcc to work for cross-compiling |
 |
|
Hello,
I followed these instructions https://forums.gentoo.org/viewtopic-p-8844162.html#8844162 to setup distcc on two machines. I am not getting any useful errors or logs, and it does not appear to be compiling on both. Networking is setup, and I am able to ssh into the helper machine. I believe I had it working earlier, because I saw messages when merging a package, but it might have been when I was merging distcc itself.
I am not sure where I went wrong, any assistance is appreciated. |

If you wish help from other, don't let other guessing  You have yet sharing anything for us to start understand what is the problem. All we know is from your statement distcc is not working.
Please use the terminology in the linked post, show us what does it mean | Quote: | | it does not appear to be compiling on both |
What kind of machines both are?
What is cross compile target?
How cross compile tool chain setup?
Using your posted link as example, tell us the setup so we can have place to start. Don't expect everybody read through the link content. |

Sorry, haha
One is a thinkpad t450s with an Intel i7-5600u, and one is an asus prebuilt desktop with an intel i7-7700
The target is the thinkpad
The profile on both machines is default/linux/amd64/23.0/hardened
I am still learning about tool chains |

Okay, I added the line CC="distcc" to make.conf on the target, and before that, I tested to make sure distcc itself was working by writing a c program and compiling using distcc, and it worked, so it seems the issue is was just getting it to work with portage. Now, I get this error when running emerge

I am not sure where to set "INCLUDE_SERVER_PORT" |

I think I have got it now. I had the hosts file on the target set to "192.166.7.79,cpp, lzo." I removed "cpp," and I am no longer getting the error. I was under the impression that portage would return messages specifically for distcc at the beginning of an emerge process, and when I run "sudo distccmon-text 1" on the helper, it wasn't displaying anything in the output.
I think I have got it working now, because I can hear it compiling! |

distccmon is run on the system needing help, not the helper.
distcc-pump has been broken for years. It needs the same (identical) include files on the helpers as the system needing help.
That allows the helpers local files to be used which saves network bandwidth.
Portage no longer supports pump mode.
Your topic title is misleading as you are not cross compiling.
Cross compiling would be using your i7 to build arm code for say, a raspberry pi.
That works too.
