linking errors compiling on aarch64
lazarus / 1-Linux

----------------------------------------------------------------------

Hi
I am trying to compile lazarus for my pinebook pro (KDE on Manjaro on
aarch64).

I used this file
Code: [Select]wget https://gitlab.com/freepascal.org/lazarus/lazarus/-
/archive/main/lazarus-main.zip

This is what I got (the last bit)
Code: [Select]make --assume-new=lazres.pp lazres

1) Locate the missing object files (I'm assuming they exist in your
file system)
2) Add -va as an option for details of where FPC is looking for the
missing object files
3) Add the location of the missing object files -or- link them to
where FPC is looking.

If the missing object files do not exist, I'm told installing libgcc
should resolve that one.

These files exist (assuming you have gcc installed, its a dependency
of fpc, along with binutils, make) in places like

Code: Text  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
/usr/lib/gcc/x86_64-linux-gnu/9/crtbegin.oBut the '9' depends on the
version of gcc you have and the "x86_64-linux-gnu" depends on your cpu
and the "/usr/lib" depends on your distribution! Sigh ...

So, find out where your (eg) crtbegin.o really is

Code: Bash  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i find /
-name "crtbegin.o" 2> /dev/null <enter>
and either edit your fpc.cfg file or (better IMHO) add a symlink.  I
have a line in my fpc.cfg that looks like this -

Code: Bash  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
-Fl/usr/lib/gcc/x86_64-linux-gnu/9
You should have something vaguely similar.

Thanks.  Your answer got rid of some of the errors.
Specifically, I added this line in /etc/fpc.cfg
Code: [Select]# path to the gcclib
-Fl/usr/lib/gcc/aarch64-unknown-linux-gnu/11.2.0

However I still have this:-

I have since discovered that lazarus and freepascal can now be
installed from pacman.  When I first got my pinebook pro this wasn't
the case and so I had to compile from source.

So now I have two installations of fpc, one in /usr/local/bin which I
installed using the install.sh from direct download of fpc, and one in
/usr/bin which pacman put there.

If there was an uninstall.sh I would probably run it....

Just to be sure, you have installed the dependencies listed on, eg, ht
tps://wiki.freepascal.org/Installing_the_Free_Pascal_Compiler#FPC_Tar_
Balls  ?
QuoteIf there was an uninstall.sh I would probably run it....

Bit late to tell you now but when you install from the FPC Tarball,
you do not have to install into /usr/ - I install into a dir in my
home dir, set it all up in there and can easily blow it away when ever
I feel like it. Thats what the example on the wiki shows ...

This is a known problem. To solve it you need the source code for FPC
3.2.2 if you don't have it already. There you navigate to
rtl/linux/aarch64 and edit the file cprt0.as (around line 40):

Code: ASM  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i         /*
__libc_start_main(main, argc, argv,                             init,
fini, rtld_fini, stack_end) */        adrp    x0,:got:PASCALMAIN     
 ldr     x0,[x0,#:got_lo12:PASCALMAIN]        adrp   
x3,:got:__libc_csu_init        ldr    
x3,[x3,#:got_lo12:__libc_csu_init]        adrp   
x4,:got:__libc_csu_fini        ldr    
x4,[x4,#:got_lo12:__libc_csu_fini]        bl      __libc_start_main 
Replace this with the following:

Code: ASM  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i         /*
__libc_start_main(main, argc, argv,                             init,
fini, rtld_fini, stack_end) */        adrp    x0,:got:PASCALMAIN     
 ldr     x0,[x0,#:got_lo12:PASCALMAIN]        mov     x3,xzr       
mov     x4,xzr        bl      __libc_start_main 
And then go one directory up (to rtl/linux) and execute

Code: [Select]make CPU_TARGET=aarch64 OS_TARGET=linux cprt0.o
Finally copy the file rtl/units/aarch64-linux/cport0.o to
/usr/local/lib/fpc/3.2.2/units/aarch64-linux/rtl/cprt0.o, replacing
the original file there.

Wow, so that means that as the new glibc is rolled out, we can expect
FPC to stop working on  aarch64, ppc64le and even poor old i386 ?

Thats going to be interesting ....

FPC itself will continue to work, cause it doesn't link to the C
library on Linux. However anything that links in the C library will
trigger this. This is something we'll have to fix before 3.2.4 is
released.

this worked thanks.
The only note I would add for future victims is that in Manjaro that
the source is in /usr/lib/fpc/src and that once the new cprt is
compiled the command to actually install it is then (if you installed
fpc, fpc-src and lazarus using the package manager):-
Code: [Select]cp /usr/lib/fpc/src/rtl/units/aarch64-linux/cprt0.o
/usr/lib/fpc/3.2.2/units/aarch64-linux/rtl/

Which looped right back round to here.

Arch say that it's nothing to do with them because I'm running
Manjaro, and Manjaro say that fpc isn't developed by them so they
won't do anything.

Basically I need to somehow find out who is the package maintainer for
fpc on Manjaro.

There is nothing that the distros can do here. This needs to be fixed
by us and then you'll need to wait for 3.2.4.
