FYI everybody.

I have gradually reduced dependencies, especially LCL dependency, between units in Lazarus sources.

One important goal is to allow cmd line programs use the Project and Package systems. LazBuild is such a?cmd line program but currently it must use a NoGUI widgetset hack. Earlier it pulled in a big number of IDE units as dependencies. Now there is only one, unit BuildManager, directly in LazBuild source but it is a nasty one and has lots of dependencies currently.

Anyway, initially reducing the dependencies felt totally frustrating and useless. Removing one dependency in one unit did not change anything. Gradually more and more units could be moved to packages without LCL dependency. I was also able to totally remove?LCL dependency from the IdeProject and IdePackager packages. Now it looks realistic to have?LazBuild without LCL!

Please test. The latest refactoring did not change the public interfaces like some earlier refactoring?did (like LCLProc etc.). However a clean build is required because units have moved.

Thanks for the heads up !

Awesome!

Great job!

Out of curiosity:

What prompted the IDE team to finally decide to have LazBuild without LCL dependencies ?

Huh? That was always a goal!?

Mattias

Really ? I remember vividly mentioning it probably 15+ years ago, in a discussion where I pronounced the NoGui widgetset an aberration, and nobody saw any problem at that time. Hence my question.

Maybe with age my memory has degraded (not only AIs have a context window). Or I missed people agreeing with me, also a possibility.

No matter, I'm glad it is being done!

Michael.

Abandoning nogui would have postponed lazbuild for 15+ years.

Also there were some more discussions about the nogui widgetset, unrelated to lazbuild.

It is not yet complete.

Juha did the tedious task of refactoring hundreds of units and dozens of packages (a lot of my code too, guilty as charged) trying to break as little as possible. Titan work.

I believe everybody considered it as a good idea but the task "LazBuild without LCL" felt?initially impossible when you only way was to reduce dependencies with small steps, realizing the ultimate goal may not be reached.?Reducing dependencies is a good idea in any case. It is an essential part of good SW design and typically improves code quality.

Thanks for the positive feedback.

Now I had time because my car repair plans were postponed a little. My golden Volvo S60 engine lost its power and gave an OBD2?ECM code 261A, "*Long-term fuel trim. Bank1*".

The web tells:?"/indicates that the long-term fuel trim is reaching its maximum limit, specifically indicating a lean mixture (too much air, too little fuel) in the lower part-load area. This commonly results from vacuum leaks, faulty fuel pressure sensors, or failing oxygen sensors./"

First I will change spark plugs, coils and fuel filter but I get the parts only tomorrow. If it does not help then I investigate more.

Now I have 3 Volvos, all bought from a net auction half-accidentally.
- Golden Volvo S60 AWD turbo automatic, year 2002.
- Silvery Volvo S60 basic manual, year 2002.
- Blue Volvo S80 T6, double turbo, year 1999.

The last one is a project (even more than the others). 5 cylinders and 1 turbo are not enough. It has 6 cylinders and 2 turbos. :) It was super-expensive then 27 years ago. I bought it with 800?.

I have a fetish for these year 2000+/- Volvos because they were made so well. Engine, rust protection etc. OK, they also have many issues after 20+ years.
I have no desire for new cars. They have tablet computers as a user interface and spy systems etc. No thanks!
I don't miss any feature from new cars, except maybe automatic high beam lights and reverse camera, but the latter does not help with reversing a trailer which would benefit from assistance.

Now these Volvos are so old that they are scrapped in a fast pace, or sold cheaply. I want to save them all. Uhhh... Maybe I should find a rehab program for Volvo addict people.

Juha

No doubt :-)

'being done' means 'in the process of doing' :-)

Yes, I imagine so. I'm all the more glad on that account...

Michael.

Still waiting for spare parts. :(

LazBuild is now free of LCL dependency. Extra dependencies are removed from LazBuild project but the makefiles are not updated. They can all be updated at one go. The current makefiles still work, they just use the old (now obsolete) dependencies.

Please test.

FYI, after delays and other hassle and a broken fuel line connector the Volvo got fixed. Replacing the spark plugs, coils and fuel filter was enough. I should have changed them earlier. Soon I will test full throttle acceleration. It may have improved a little, too. At least the engine runs very smooth now.

CI/CD pipeline failed at last commit, but it should not according to your comment about makefiles ?

I did "make all" and "make bigide" and such, and compiled everything through Lazarus IDE. Why would the?pipeline fail?

I am working with FPC trunk now but the?last commit does not have anything related to?FPC trunk.

If I remove BuildManager unit from ideproject package then it compiles ideproject package, but again errors in lazarus ide units where BuildManager unit is included. Where is actually BuildManager unit now ?

Seem that you forgot to add and commit unit buildmanager, because no such unit exists in lazarus branch.

it breaks the compilation for big endian platform as far as I see at least for me it breaks
