Hi,
sorry, that I did not respond in time. I also had issues with "slang" during one of my latest test builds, especially when using something like "-j3" (it always worked fine when using higher values). The lfs manual also stated that the build of "slang" cannot be parallelized. Sorry, I apparently overlooked that (I have now checked all other packages and did not find incompabilities).
Today, I started again some more builds (with parallel build disabled for slang), the test continues tomorrow.
Best regards, Wolfgang PS.: The builds always use the branch that Michael created.

Hi,
Sorry for not being able to get around to this earlier, but I have
invested some time on this:
First of all, I merged Wolfgangs patch. He is right, the build is too
slow. It sometimes looks a bit like it is not taking enough advantage of fast systems. On the other hand with have small systems, which are (in their own right) quite fast. Those are the ARM systems. They usually have 1G of RAM. 2GB when you are lucky.
So I adjusted make.sh a little bit and removed composing the MAKETUNING
variable from it.
Now, make.sh only figures out the value that usually comes after the -j.
It is set in DEFAULT_PARALLELISM.
In the individual LFS files, we can now set a new variable called
MAX_PARALLELISM which is optional. In boost, I now calculate this from the amount of memory that is available. That will make sure that we have a cap on this that will be high on systems that have the memory and low on those that dont. Before, we hardcoded -j2 which of course runs very slow on large systems.
The code is here:
https://git.ipfire.org/?p=people/ms/ipfire-2.x.git;a=shortlog;h=refs /heads/faster-build
Please review. I am now running this on a couple of builders and will
see what comes out. Please do the same and send me feedback.

Hi Arne,
of course I did delete the ccache between my multiple builds to verify
the commit. To play it safe, I hard reset using git, checked that all folders (build, ccache, etc.) are gone and restarted the build after gettoolchain and downloadsrc.
Sorry, I did not know that there are still a lot of machines with low
ram that we are using to build ipfire. My hope was that these machines have disappeared over the last years.
Additionally, I do not have the ability to test all ipfire arches, as
mentioned, the patch needs testing by others.
I also thought of adding a manual parameter for developers that somehow
manually sets the parameters for parallel build, but since the MAKETUNING parameter already exists and is used with other packages this would just somehow mess everything up.
For my builds, I can just manually apply the patch to speed up the full
build. My thought was that sharing the patch would make sense for others.

On the most of this packages (eg. boot and cmake) i have disabled parallel build because it fails on machines with low ram (less than 2GB) or on arm. So such changes need tested on an 1GB machine, on all architectures and build two times after deleting ccache. Because the build need much lower resources if it has the file already
prebuilt in cache.

Don't know why. I tried two builds, same error.
Best, Matthias
I think that we are saving about 30 min to an hour on the nightly builds
now… Did anybody else run some benchmarks?

Hi,
Sorry for not being able to get around to this earlier, but I have
invested some time on this:
First of all, I merged Wolfgang’s patch. He is right, the build is too
slow. It sometimes looks a bit like it is not taking enough advantage of fast systems. On the other hand with have small systems, which are (in their own right) quite fast. Those are the ARM systems. They usually have 1G of RAM. 2GB when you are lucky.
So I adjusted make.sh a little bit and removed composing the MAKETUNING
variable from it.
Now, make.sh only figures out the value that usually comes after the -j.
It is set in DEFAULT_PARALLELISM.
In the individual LFS files, we can now set a new variable called
MAX_PARALLELISM which is optional. In boost, I now calculate this from the amount of memory that is available. That will make sure that we have a cap on this that will be high on systems that have the memory and low on those that don’t. Before, we hardcoded -j2 which of course runs very slow on large systems.
The code is here:
https://git.ipfire.org/?p=people/ms/ipfire-2.x.git;a=shortlog;h=refs
/heads/faster-build
Please review. I am now running this on a couple of builders and will
see what comes out. Please do the same and send me feedback.

Yes, probably.
It uses a lot of memory when compiling because it is C++.
I will adjust the number of concurrent processes just like we did for boost.
