[SOLVED] link error on Ubuntu 22.04 LTS (GNU/Linux 5.10.140 aarch64)

[senglit]

Hi,

I have a project which can be built successfully on X86-64/Windows and arm-linux-32bit(Cortex-A9/armhf). Now I have my hardware/software changed to Cortex-A35/aarch64, software version:Ubuntu 22.04 LTS (GNU/Linux 5.10.140 aarch64).

First I installed gcc lib by

Code: Text  [Select][+][-]

1. apt install build-essential
2.  

Then, I downloaded fpc-3.2.2.aarch64-linux.tar and installed FPC by command ./install.sh. Then I began to build my project by:

Code: Pascal  [Select][+][-]

1. fpc devices485.lpr -Fulnet\* -Fusysnapse40.1\*          #it works on Cortex-A9/armhf
2.  

But then I got these messages and I got no idea how to solve it. Any body can help? thanks!

Fixed in trunk see #39295

[senglit]

Thank you. I took a look at issue #39295 and tried to install FPC from source file. But I'm really not familiar with fpc make and failed several times.

Is there any package which already solved this issue and can be installed by simply ./install.sh ?

Fixed in trunk see #39295

[TRon]

Yeah, sorry. I noticed trunk did not build starting this week or so.

You could try here.

Select the directory that matches desired platform and see if there the build listed is newer than the date of the commit mentioned in the issue-report (should be no problem).

PS: don't mix your installations though. Make sure to backup your existing FPC 3.2.2 configuration in case installed when used a package-manager and/or .deb file.

Back to the original question, here are scripts based on mine, with small differences.
For Ubuntu or Debian or Raspberry OS, clean new install:

Code: Bash  [Select][+][-]

1. #!/bin/bash
2. #
3. # script for installing a completely fresh trunk version of freepascal
4. # does not use fpcupdeluxe and install according to OS rules
5. # you run this only once! after this you should run the updfpc.sh script
6. #
7.  
8. # Get the user’s home directory (works with sudo)
9. if [ -n "$SUDO_USER" ]; then
10.     user_home=$(getent passwd "$SUDO_USER" | cut -d: -f6)
11. else
12.     user_home="$HOME"
13. fi
14. cd "$user_home"
15. apt install git
16. git clone https://gitlab.com/freepascal.org/fpc/source.git fpc
17. apt install build-essential
18. # not a full install, just the basic compiler and tools
19. apt install fp-compiler
20. # Then build the full compiler:
21. cd "$user_home/fpc"
22. make clean all install PP=/usr/bin/ppca64-3.2.2 PREFIX=/usr
23. # Copy over the newly build compiler (or create a symlink).
24. cp /usr/lib/fpc/3.3.1/ppca64 /usr/bin
25. exit 0

You can save this shellscript as e.g. newfpc.sh and make it executable. You should run it with sudo rights

To update an existing install:

Code: Bash  [Select][+][-]

1. #!/bin/bash
2. #
3. # script to update an existing install
4. #
5.  
6. # go to fpc directory
7. # Get user’s home directory (works with sudo)
8. user_home=$(getent passwd "${SUDO_USER:-$USER}" | cut -d: -f6)
9.  
10. # Attempt to cd into ~/fpc
11. if cd "$user_home/fpc"; then
12.     echo "Success! Now in: $(pwd)"
13. else
14.     echo "Error: $user_home/fpc does not exist." >&2
15.     exit 1
16. fi
17. cd "user_home/fpc"
18. # update sources
19. git pull
20. # make the new compiler
21. make clean all install PP=/usr/bin/ppca64-3.2.2 PREFIX=/usr
22. # Copy over the newly build compiler (or create a symlink).
23. cp /usr/lib/fpc/3.3.1/ppca64 /usr/bin
24. exit 0

Save as e.g. updfpc.sh , make executable and run with sudo rights

I just noticed a small error in the update script:
It works, but only once. You can run it once but a second time fails because then the renamed compiler ppcx64-322 becomes actually the trunk compiler
I will fix that.FIXED
Cause: I overlooked that installing the fp-compiler package already creates a symlink /usr/bin/ppcx64-3.2.2, so it is not necessary to rename the compiler.

Parts of the scripts are snippet based, so there maybe room for improvement, but this works.

There is Fpcupdeluxe for aarch64-linux https://github.com/LongDirtyAnimAlf/fpcupdeluxe/releases/tag/v2.4.0f.

[senglit]

Still struggling.

[TRon]

OMG. just pick /one/ method and stick to it. Going the yolo route only provides more issues down the road.

prerequisites for FPCUpDeluxe on linux

E: Unable to locate package fp-compiler

What distribution are you using that it does not contain package fp-compiler ?

btw not required for FPCUpDeluxe, only if you install the FPC compiler manually (and on top of that install Lazarus manually).

tar file from https://downloads.freepascal.org/fpc/snapshot/trunk/aarch64-linux/ : unpacked with 3 folders: bin, share, lib. I don't know how to install it.

Yeah I noticed the installation script is missing from that tarball. No idea why. Also not required for FPCUpDeluxe.

First, pick a method (and stick to it). There is no use cooking up a script if you're going FPCUpdeluxe route anyway as it does everything for you (except install the dependencies. Might require to install the dev packages for these dependencies as well when using a debian based distribution).

[senglit]

Thanks!
I stick to fpcupdeluxe and ... I still failed on building FPC enviroment on aarch64-linux, but I built a cross compile enviroment on win11 which can build executable file for any cpu and os. Giving I write my source code on win11, it's even better than buiding env on aarch64-linux.

I stick to fpcupdeluxe and ... I still failed on building FPC enviroment on aarch64-linux,

Failed is a non-computable terminology (fwiw: it works for me but at the same time some trunk combinations of FPC/Lazarus might fail to build...)

but I built a cross compile enviroment on win11 which can build executable file for any cpu and os. Giving I write my source code on win11, it's even better than buiding env on aarch64-linux.

Good that you got it solved. Thank you for reporting back.
