Preparing my Stack for Android and Blockchain

[Fred vS]

There is no SVN server at that address any more. The project(s) moved to git back in June-July.

Hi dsiders!

Please, can you point up to the new [direct] access to FPC source and how to download it?

In complement with dsiders answer there is also the direct access to the up-to-date last trunk zip file, ready to download:
https://gitlab.com/freepascal.org/fpc/source/-/archive/main/source-main.zip

And here of fixes 3.2:
https://gitlab.com/freepascal.org/fpc/source/-/archive/fixes_3_2/source-fixes_3_2.zip

And here of release 3.2.2:
https://gitlab.com/freepascal.org/fpc/source/-/archive/release_3_2_2/source-release_3_2_2.zip

Hi, Webdrifter!

After the helps from dsiders and Fred vS (thanks to All!)

You can "bypass" this taks/form  [out of date]...

Get FPC source (unzip it!) and then go to the next task:

2. IDE "Tools" --> "[Lamw] Android Module Wizard" --> "Build FPC Cross Android"

[Webdrifter]

From the reactions above I understood, that when performing step

1. IDE "Tools" --> "[Lamw] Android Module Wizard" --> "Get FPC Source [Trunk]"


In the window at position "FPC Source Trunk Download"

I should not have :

http://svn.freepascal.org/svn/fpc/trunk


But I should now have to change it first to:

https://gitlab.com/freepascal.org/fpc/source/-/tree/main

So i tried this and got the next error.

[Webdrifter]

And I also don't understand why I would need FPC 3.2.2.

Did you not say earlier that FPC 3.2.2. was already in Lazarus 2.0.12?


And if this all means that step with SVN is unnecessary, then maybe installing sliksvn was a unnecessary step? And sliksvn can be uninstalled? Or not?

From the reactions above I understood, that when performing step

1. IDE "Tools" --> "[Lamw] Android Module Wizard" --> "Get FPC Source [Trunk]"

No! this step is "out of date" forget it!

Get FPC source as point up by "Fred Vs" and unzip it in some folder....... and then go to the next task:

2. IDE "Tools" --> "[Lamw] Android Module Wizard" --> "Build FPC Cross Android"

And I also don't understand why I would need FPC 3.2.2.

Did you not say earlier that FPC 3.2.2. was already in Lazarus 2.0.12?

You need FPC source code to produce the cross-compile to Android

And sliksvn can be uninstalled?

Yes!


Side note:
as soon as possible I will be updating the framework with this new information....
Thanks to All!

[Webdrifter]

OK, thanks. I am very busy for my work right now. So I will try tomorrow.

[Webdrifter]

In the build tab I have to choose an FPC path.

I find the next paths to FPC 

C:\lazarus\fpc\3.0.4\bin\x86_64-win64
C:\lazarus\fpc\3.2.0\bin\x86_64-win64

Which one should I choose?

Do I need to have both on my PC?
Or can I just as well delete the 3.0.4 path?

I understood Lazarus 2.0.12 supported 3.2.2,
so Why is there no 3.2.2 path?

Is it wise to create such a path?
And if yes, how do I do that (Meaning how to get the right files and such in there)?

Next I am asked to choose an Architecture.

Which one should I choose?

Why do I have to choose it here, instead of everytime when I need to create a build of a program I made?

Can't you make your app work for more architectures then one?
(I don't see all kind off versions in the app-store for every single architecture)

Why do I have to choose it here,...

To make your FPC cross-compile to Android....

instead of everytime when I need to create a build of a program I made?

Yes, so will be.. 

Can't you make your app work for more architectures then one?

Yes, so will be.. 

[Webdrifter]

Sorry, this is not what I had question about.
I understood that I had to unzip source in some folder and fill in that folder as path in first field "Path to FPD Source Code".

So I allready unzipped FPC source 3.2.2, placed it in folder and filled in the name of this folder in first field of window "FPC Android Croos compiler Builder"

In the second field I filled in path to NDK.
"C:\Android\android-ndk-r21e"

But Third path asks for "Path to FPC" 

As said for this I find 2 possibilities.

C:\lazarus\fpc\3.0.4\bin\x86_64-win64
C:\lazarus\fpc\3.2.0\bin\x86_64-win64

I don't see: C:\lazarus\fpc\3.2.2\bin\x86_64-win64
This confused me because I thought Lazarus 2.0.12 suppors FPC 3.2.2.

So as asked, which do I choose and is it not possible to get version FPC 3.2.2 for this.

By the way the files and the directory structure of the unzipped version 3.2.2 source code don't look anything like those in

C:\lazarus\fpc\3.0.4\bin\x86_64-win64
or
C:\lazarus\fpc\3.2.0\bin\x86_64-win64

So I was afraid to use the path to the source code in the third field.

Are you telling me I should use that path in third field?


Next you show me text with:

Suggesting I should make build for "Armv7a + Soft"
and for "aarch64"

But i can only choose one off those at once.

Do you mean to say I have to do the process twice, so once for each of those architectures?

No. So,  use: "C:\lazarus\fpc\3.2.0\bin\x86_64-win64"

Yes!

[Webdrifter]

The first build with "Armv7a + Soft" gave lots of messages and warnings,
see text file attached.

Are those warnings reason for taking any actions from my part?

Anyway the build , ended with green bar of succes.

Install also went good.

The second build with "aarch64" gave no messages or warnings,
but build and install also ended with succes.

So time for the next step....

[Webdrifter]

Is it still necessary to take these steps:

3. After "build" and "install" the cross-compiler and before to create your first LAMW project

            [How to fix "Fatal: Cannot find unit system used by fcllaz of package FCL."]

            3.1) Go to "fpc.cfg"  [ex. "lazarus\fpc\3.2.0\bin"]

               Change:
 
               # searchpath for units and other system dependent things
               -FuC:\lazarus1864\fpc\$FPCVERSION/units/$fpctarget
               -FuC:\lazarus1864\fpc\$FPCVERSION/units/$fpctarget/*
               -FuC:\lazarus1864\fpc\$FPCVERSION/units/$fpctarget/rtl

               To:

               # searchpath for units and other system dependent things
               -FuC:\lazarus1864\fpc\3.2.0/units/$fpctarget
               -FuC:\lazarus1864\fpc\3.2.0/units/$fpctarget/*
               -FuC:\lazarus1864\fpc\3.2.0/units/$fpctarget/rtl

            3.2) Go to Lazarus IDE menu "Tools" --> "Options" --> "Environment" 

               [FPC Source]

               Change:
                  $(LazarusDir)fpc\$(FPCVer)\source
               To:
                  $(LazarusDir)fpc\3.2.0\source

Good work!

Congratulations!!!

               Change:
                  $(LazarusDir)fpc\$(FPCVer)\source
               To:

A good question, since the compiler should expand the $FPCVERSION macro to its own version.  Similarly the Lazarus macro $(FPCVer) should expand to the selected compiler version.

Typically these macros work, which is why they are often used in configurations.  Perhaps this was to work around some other issue, maybe cross compiler specific?

[Webdrifter]

I hope someone can answer my question about step three.
Because I would like to know how to proceed.

Also I saw that I forget to include the text with the warnings I got during build. So here it comes, maybe of interest for the specialists on this forum.
