Riscv GCC 4.9.2無法編譯linux 3.14.29

當我使用riscv gcc（verison 4.9.2）編譯linux（版本3.14.29）時，出現了一些錯誤，似乎gcc無法識別一些操作碼，我該如何解決？將gcc更改爲版本4.6？感謝Riscv GCC 4.9.2無法編譯linux 3.14.29

您是否使用riscv-tools的主分支和riscv-linux的主分支？（而不是riscv-gnu-toolchain的主分支，但是riscv-tools master repo指出的任何提交）。 – Chris

是的，我使用riscv-tools的master分支和riscv-linux的master分支，請看下面我的安裝步驟 – lei

下面是我安裝riscv-tools和linux的步驟，有什麼不對嗎？ – lei

有一個錯配你的倉庫（這可能不是你的錯）。您可以嘗試查看「new_privileged_isa」分支機構，但問題是RISC-V特權SPEC（截至2015年4月30日）仍然不穩定，我們無法保證分支機構的負責人能夠一起工作。

謝謝你，我會嘗試「new_privileged_isa」分支 – lei

檢查出「new_privileged_isa」分支爲我工作。謝謝。 – plafratt

克里斯，我用下面的方法來安裝riscv工具：

git clone https://github.com/riscv/riscv-tools.git 
git submodule update --init --recursive 
./build.sh

，並使用以下方式來獲得Linux源代碼：

curl https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.14.29.tar.xz | tar -xJ 
cd linux-3.14.29 
git init 
git remote add origin https://github.com/riscv/riscv-linux.git 
git fetch 
git checkout -f -t origin/master
