c++: error: '-march=native': ISA string must begin with rv32 or rv64

[marklove5102]

我认为最少要像

https://github.com/StanfordLegion/legion/blob/f7d3bbe27c994879528c4a7b0e19cd09bea29daf/CMakeLists.txt#L153
这样写才合理吧
不然riscv下编译不认

co_context/cmake/CompileOption.cmake

Line 18 in 21e3d25

target_compile_options(co_context PUBLIC -march=native)

的-march=native

大概找了下解决方案
advancedtelematic/aktualizr#1427
android/ndk#10

我只是体验下riscv 开发。

[marklove5102]

在

co_context/cmake/CompileOption.cmake

Line 48 in 21e3d25

target_link_libraries(co_context PUBLIC Threads::Threads)

添加
atomic

target_link_libraries(co_context PUBLIC Threads::Threads atomic)

编译通过

好吧是时候，结束体验。

牛逼👍
看来 riscv 还需要额外的系统调用支持。

[Codesire-Deng]

我想问下如果要复现你的环境，需要哪些工具，能否给些关键词？

[marklove5102]

riscv64 docker可以使用服务器的所有CPU

docker 执行
docker run -it -v /usr/bin/qemu-riscv64-static:/usr/bin/qemu-riscv64-static riscv64/ubuntu:23.04 /bin/bash
如果 上面语句exit了

docker container ls -a
找到这个容器的id
执行进入容器bash环境
docker exec -it 容器id bash
如果重启了没设置常驻后台开机自启
启动容器 再进入bash环境
docker start 容器id
