failed to merge target specific data of file: can't link single-float modules with double-float modules #134

TL; DL turns out that kendryte ide will download a fullset of riscv gnu toolchain, i am wondering what the configure and compile flags is the version. it can build the sdk anyway

Hello, I am new to RISC-V and C toolchains, when trying to build the example given in the README

Actual behavior

Test code

sed -i 's/-unknown-/-/g' cmake/toolchain.cmake
mkdir build && cd build
cmake .. -DPROJ=hello_world -DTOOLCHAIN=/usr/bin
make

Document version

default branch, HEAD

System

ArchLinux

I also had ran into other problems too. Tested with the latest GNU RISC-V toolchain on GitHub built from source on two different machine leads to the same error: No SOURCES given to target: hello_world

simply add ${...}/bsp to include dir in CMakeList.txt of lib and add include "locks.c" leads to tons of linker errors.

I use the following to compile the toolchain. Works fine with K210 and GD32V based boards. For K210 the --with-arch=rv64imafcand --with-abi=lp64f are the magic flags.


$ git clone --recursive https://github.com/riscv-collab/riscv-gnu-toolchain.git
$ cd riscv-gnu-toolchain

$ mkdir /opt/riscv
$  ./configure --prefix=/opt/riscv --enable-multilib --with-cmodel=medany \
   --with-arch=rv64imafc --with-abi=lp64f
$ make -j8
$ make install
