我想使用 riscv-gcc 在 Arty-A7 上实现 Ibex(RISCV 核心)示例,但我无法正确构建它。在“制作”阶段之后它一直在失败。它似乎与 zlib 有关,但我不太确定,因为这是我第一次从源代码构建任何东西。我从https://github.com/riscv/riscv-gcc获得了源代码
我已经配置它执行 make as
../riscv-gcc/configure --enable-multilib
make
然后它退出并出现以下错误
checking whether the gcc -m32 linker (ld -m elf_x86_64 -m elf_i386) supports shared libraries... yes
checking whether -lc should be explicitly linked in... no
checking dynamic linker characteristics... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.
make[2]: *** [configure-stage1-zlib] Error 1

make[1]: *** [stage1-bubble] Error 2
make[1]: Leaving directory `/home/alfred/Desktop/Work/riscv_gcc_install'
make: *** [all] Error 2
我也尝试过运行 make (相同的配置)
make all-gcc
但它会产生此错误
checking if gcc -m32 supports -fno-rtti -fno-exceptions... no
checking for gcc -m32 option to produce PIC... -fPIC -DPIC

make: *** [configure-zlib] Error 1
除了按照https://gcc.gnu.org/install/prerequisites.html的建议检查必备库之外,我不确定到目前为止该做什么。谁能帮我吗?

我尝试从 < https://github.com/riscv/riscv-gnu-toolchain > 安装完整的 riscv-gnu-toolchain 以避免丢失依赖项,但是我仍然遇到错误。我确实运行了建议的 apt-get 命令来安装先决条件。
我运行了建议以 riscv32 为目标的配置,并按如下方式进行 make
./configure --prefix=/opt/riscv --with-arch=rv32gc --with-abi=ilp32d
make linux
然后我得到了这个错误

我注意到 m4 无法识别某个参数
--gnu
我应该关心这个吗?

按照建议,我尝试在 Ubuntu 18.04.03(最初我在 14.04)中构建工具链,它似乎已经很好地解决了这个问题!事实证明,当涉及到操作系统依赖项时,工具链确实是“脆弱的”。非常感谢你的帮忙!
