Assembler error ‘illegal operands’ when compiling on RISC-V 64 computer

[yurets_z]

I’m new to the topic of compiling the IDE from source and crosscompiling.
I found it interesting to try porting a couple of my Lazarus GUI projects on RISC-V 64 SBC (VisionFive 2) operating under Debian OS.

For that I used a cross compiled version of FPC 3.3.1 from trunk  (http://downloads.freepascal.org/fpc/snapshot/trunk/riscv64-linux/fpc-3.3.1.riscv64-linux.built.on.x86_64-linux.tar.gz) and Lazarus 3.4.0 source files.

When trying to build the IDE (via “make clean all” ) I get the following output and assembler error in the mid of the process:

I guess the complain is about ireg32 and ireg33 operands. Any ideas/suggestions about the reason and how that could be fixed?


Kind regards,
