Hi, You should definitely get a failure at bridges I guess ;-):You definitely have porting work before you. See e.g. https://cgit.freedesktop.org/libreoffice/core/tree/bridges/source/cpp_uno/gcc3_linux_aarch64 for arm64. You need to know the ABI and calling conventions.
Update here: I headless copyed mips64 in bridge source into riscv64
(fix calling conventions for riscv64 is not easy thing for me now).
It seems it was passed for riscv64 bridge "build check". But it stops
at pdfium here:

It seems the build_config.h can not detect the cpu info. If anyone has interesting to try it, please apply the patch and add riscv64 support for d/rules. BR, Bo
