Documentation on compiling project using command line?

[MISV]

What is the best resource for command line usage?

Select project. Select release define. Compile. I do not need much really. I can use this for both Mac and Windows. I need to automate everything because otherwise I will mess up

I need to setup a build process bat file or similar on my Mac

Thank you. I will check it out.

It is unfortunate there isn't a Lazarus commandline... That could load project and compile


TIP for other

I looked into messages when compiling > right click > about compile project


There one can see all information including a *huge* command line instruction. I will use that start case. I will report back

oh, but there is. It is that you posted this in the Free Pascal subforum 

It is named lazbuild and afaik that is the definitive guide to using it (yes, it is indeed a bit scarce)

[MISV]

Thank you

It is actually very close I have gotten it working calling FPC directly...


If all .lib files already has been generated by Lazarus earlier (in my command line script I am actually removing these before building to ensure 100% all of my code gets recompiled with updated defines found in include files.)

Then... it actually compiles the executable on MacOS (one has to change directory to the project directory first if using the command line grabbed from the "Messages > About compile project") and... it appears to run without errors

...

However if I remove .lib files from a shared source directory (not placed in project directory) it stumbles:

Any ideas what to try? Kinda peculiar problem occurs when running commandline and not when Lazarus runs command line. Maybe Lazarus does some preparation I am not yet duplicating fully.


This is the entire unit by the way:

1. unit UmsSysExceptions;

3. interface
4. uses
5.   SysUtils
6.   ;

12.   EmsParamTypeWrong = class(EmsParamWrong);
13.   EmsParamOutOfValidRangeError = class(EmsParamWrong);
14.   EmsParamsOutOfValidRangeError = class(EmsParamWrong);
15.   EmsParamsMisMatchError = class(EmsException);
16.   EmsMissingRequiredHandler = class(EmsException);

35.

As can be seen the declarations are some general ones I use for own purposes.

There will be still an issue between the different (cross) compilers and options.
I am working on a small utility that shows what a specific compiler or cross-compller actually supports.
Will post it here.

Reason: the number of options available are dependent  on the platform for which the compiler is supposed to compile.
And the way I approached it always get the information from the compiler itself, so it documents more current than the documentation. Will post a bit later....
It basically filters all the -i<x> output. Since that info is taken from the compiler itself, it is always more current about available options.
( main reason: I am almost always on trunk/main )

[MISV]

Quick note: In this case both the command line compilation and Lazarus compilation is on Mac (so no cross compilation), so should be 100% the same. I will try experiment. Maybe Lazarus is doing some cleanup before calling the FPC compiler

[MISV]

I solved this myself:

Code: Pascal  [Select][+][-]

1. UmsSysExceptions.pas(45) Error: (9002) Can't create assembler file: /Volumes/DiskW/projects/MyProject/lib/x86_64-darwin/UmsSysExceptions.s

Simply make sure
/Volumes/DiskW/projects/MyProject/lib/x86_64-darwin/
directory exists

...

Now getting other erros, but I am making progress. Hopefully this thread will become useful to other who want to use commandline. (So extremely helpful one can see in Lazarus Message right click menu the entire commandline used.)

[Thaddy]

Screenshot. almost finished: open the compiler for what you need the options from and it tells you what the options are and what is supported.
I will add the project later today.
You will open the compiler of choice and the program gives you an overview for that specific compiler.
This *should* work for any compiler from the 3.x.x series.

This is the best Free Pascal command-line reference information there is.

If you use the makefiles to build FPC rather than manual invocations, I'd suggest the buildfaq, old as it is.
