 |
|
Has anyone succeeded to compile fpc on aarch64 for raspberry pi 4 ?
I get the same error trying to compile fpc-3.2.0 no matter if a use fpcupdeluxe (tried both 1.6.2x and 1.6.2y) or if manually compile it on a chroot using static-user qemu on gentoo amd64 machine. Root or normal user make no difference using fpcupdeluxe.
The error is:
| Code: | make packages_smart FPC=/root/fpcupdeluxe/fpcsrc/compiler/ppca64 FPCFPMAKE=/root/fpcupdeluxe/fpcsrc/compiler/ppca64 RELEASE=1 'OPT=-Sg -vw-n-h-l-d-u-t-p-c-'

fpcupdeluxe: ERROR: FPCNativeInstaller (CleanModule: FPC): Error running make for FPC failed with exit code 512
. Details:
ERROR: Fpcupdeluxe fatal error !
Tried with 3.3.1, 3.2.0, but the same error keep appear and posted the issue on github @fpcupdeluxe, too.
Thank you!

costel78,
Looking at the ebuild for fpc-3.0.4 it tries to download an arch specific binary to use in the build process.
Following the amd64 location, there is no arm64 prebuilt binary.
fpc is rather like rust, gcc and other things that are written in themselves.
I suspect that fpc is written in fpc.
That leaves cross compiling, which is the only way to port these things to a new architecture.
Cross compiling using the ebuild fails too. That's fairly common.
Its not clever enough to use the amd64 binary to build an arm64 binary so that arm64 can build its own.
I don't have time to poke at that right now but its probably not trivial.

NeddySeagoon,
Yes, it is not trivial. Stable branches for both freepscal and lazarus do not support aarch64.
fpc-3.2.0-beta and lazarus 2.1.0 branch are required, minimum, so I am not trying to compile them using an ebuild.
I downloaded sources, fpcbuild and already compiled snapshot - aarch64-linux/fpc-3.2.0-beta.aarch64-linux.tar.gz and tried to compiled them in aarch64 chroot on amd64 machine.
Compile failed at the 3rd stage, no mater what branch I used: trunk, fixes3.2 or 3.3.1 so I looked for alternatives and I found fpcupdeluxe.
Using fpcupdeluxe on raspberry itself or on chroot gave me the same error as above:
| Code: | | /usr/bin/ld: /usr/lib64/libc_nonshared.a(elf-init.oS): in function __libc_csu_init': (.text+0x4c): undefined reference to _init' |
On arm (32 bits) using fpcupdeluxe the error does not appear.
I am looking for an explanation of what I am doing wrong, or a patch if it is a freepascal error.
Thank you for your support!

I am hoping when FPC 3.2 is officially released the minimum build for Lazarus goes up to 3.2.
Then is should be easier.
At the moment the binary aarch64 3.3.1 version works and I can compile simple stuff with Geany.
As Sakaki's Gentoo64 has better OpenGL support(and seems more reliable than current Buster 32/64 )I'm looking forwards to trying that on Gentoo64 and not Buster 32.

Yes, I am hoping this too, but 2.0 ver does not support aarch64.
Using binary precompiled fpc-3.2 beta I am able to compile Lazarus 2.1.0 from svn. But this is not "the Gentoo way" where everything is compiled from source.

I was having a lot of fun on Buster using fpc and doing OpenGL coding.
Laz/fpc build from source is the normal way, it;s just the build tool needs to work on Arm64.
Not sure how ebuild/Laz/fpc works, don't know enough about Gentoo yet.
Anyway there is some new stuff in Mesa 19.3 that will be nice to try.
Guess we have to wait.

Or learn how to use 32bit chroot.
Sakaki has got it to work that way. o
Since my Pi baremetal fpc stuff is only 32bit at the moment perhaps chroot is next for me to learn in Gentoo.

First, thank you for your support.
Right now, 32 bits chroot is a bit unpractical, for my needs. I built my own arm32 and arm64 gentoo, both using precompiled fpc and ebuild compiled lazarus. Lazarus is needed only for compile, for client just binary app is all they want. I am not using OpenGL to much, BGRABitmap and related are ok on raspberry, just a little slower than on x86.
The goal was to reduce costs using raspberry, so I had to adapt/recompile some older app to work on raspberry/Gentoo OS. Not using Lazarus to much, anymore, doing web development lately. The main issue with freepascal was that you have to keep a list of installed files as the things will evolve and, at some point in the future, an ebuild will be available and manually installed files will have to be removed. They provide an installer, but not an uninstaller

Yep love those fpc binaries.
Clients wants a change I can fix and compile in minutes and even emailed one fixed OS to Russia from Oz.
That has to be a record long distance mod for me.
I have not done much fpc on Gentoo yet, a few years only IDE on Windows, running on Pi's.
Never had any luck with BGRABitmap, I keep breaking my Lazarus IDEs.
FPVectorial is getting more interesting.
WebGL on Pi4 works especially in Sakaki's Gentoo64.
I so want to learn things like three.js
Looking at fc/js tools now.
Can I embedded a JS interpreter in my apps/OS? Besen's lib?
While fpc/laz installs are big they are portable, even run from USB stick.
Some OS's install them in /usr/... trying to fix those drives me crazy.
fpcupdeluxe tends to install in user directories, a bit easier to figure out.
A Portable USB install that runs on every x86/arm/arch box would be nice.

Regarding JS interpreter there are a native pas2js and it was quite good when used it.
Yep, portability and static linking are great and made me to choose Lazarus over Java.

Anyone making any progress on building FPC on aarch64 on a Pi 4?
I have an application I'd like to build that requires it. There are 32-bit binaries of the application for the Pi 3 but it is not the current version that has bug fixes I need. |

You can build it manually, you can use precompiled binaries for 3.2.0 (installed on /usr/local), or can use fpcupdeluxe.
I was unable to compile Lazarus on aarch64 - linker error during build.
