Dear all...

finally I found some time to progress on my raspberry pi apache module project... at least it compiles now.
Though my problem is now the linker. When compiling the apache module I get the following errors:

Warning: linker: /usr/bin/ld: /home/pi/fronius/ApacheWebModule/FPC/lib/aarch64-linux/mod_fronius.o: relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `fronius_module' which may bind externally can not be used when making a shared object; recompile with -fPIC
Error: /home/pi/fronius/ApacheWebModule/FPC/lib/aarch64-linux/mod_fronius.o: in function `P$MOD_FRONIUS_$$_main':
Error: /home/pi/fronius/ApacheWebModule/FPC//mod_fronius.ppr:37:(.text.n_p$mod_fronius_$$_main+0xa4): dangerous relocation: unsupported relocation
mod_fronius.ppr(42,0) Error: Error while linking

I have no idea what to do here... actually I also added the option -fPIC as suggested in the warning and did a complete rebuild with no effect.

Anyone has actually a clue what that error could mean?

kind regards

Dear moderator.

I currently use 8.3 on a raspi 4B - I think it's the "bookworm" release I use...

I just stumbled over
forum.lazarus.freepascal.org/index.php?topic=24440.0
could that be a solution and if so how do I apply that on codetyphon?

 
 

My suggestion
Use CT ver 8.4 or LAB ver 8.5

I updated to 8.4 via the update manager... still the same problem.
Does this error ocure due to a third party shared module, a package or is this a general error when creating an apache shared module? I don't understand the source of the problem :/

I have the same problem if I create an empty fresh new apache module :/

Finally - I think I found the reason why the linker is having troubles.
In the standard apache export there is the module record exported! If one accesses this record within
the shared module the linker starts to complain.

How can I circumvent this?

My idea would be to export a function that returns the content of the apache module but I'm not sure if apache allows that
