reent.h: No such file or directory

我们依照这个方法在LicheePi4A的板子上面进行编译的

apt install git make cmake binutils-riscv64-unknown-elf gcc-riscv64-unknown-elf picolibc-riscv64-unknown-elf
git clone https://github.com/sipeed/RV-Debugger-BL702
git submodule update --init
cd RV-Debugger-BL702/firmware/bl_mcu_sdk
echo "add_compile_options(-specs=picolibc.specs)" >> tools/cmake/compiler_flags.cmake
echo "add_link_options(-specs=picolibc.specs)" >> tools/cmake/compiler_flags.cmake
make

结果报错了

能看下是什么原因么？

After remove the
echo "add_compile_options(-specs=picolibc.specs)" >> tools/cmake/compiler_flags.cmake
echo "add_link_options(-specs=picolibc.specs)" >> tools/cmake/compiler_flags.cmake
And then we move to compile with the latest riscv64 toolchain, it compile success.
But we met the new issue with link

It seemed that the project has something conflict with the 64bits riscv toolchain.

换编译器，装的版本不能用，下个FreedomStudio

[a7-github]

solved in #21
