Multilib #121

Closed nutcakes closed 5 months ago

nutcakes commented 7 months ago

When I run the command riscv64-unknown-elf-gcc -O1 -mabi=lp64 -march=rv64i -o sum1ton.o sum1ton.c riscv64-unknown-elf-gcc: fatal error: Cannot find suitable multilib set for '-march=rv64i'/'-mabi=lp64' compilation terminated. I get this error. Also when running spike pk sum1ton.o with command riscv64-unknown-elf-gcc -Ofast -o sum1ton.o sum1ton.c I get the error libc++abi: terminating due to uncaught exception of type std::invalid_argument: Specified ELF can't be mapped: Invalid argument. Would anybody help out? Thanks in advance.

Not all combinations of arch and abi are compiled by default. The "multilib" support this repo provides is the same as https://github.com/riscv-collab/riscv-gnu-toolchain provides by default. If there is a combination of abi/arch you want that is not part of the default multilib, you will need to build the tools manually from the repo, and specify that abi/arch combo when you configure the build.
