cocotb无法加载VPI模块

Question

在尝试编写endian_swapper示例代码时，我收到以下错误消息。我使用的是Ubuntu 19.10。

任何帮助都是非常感谢的。

谢谢。

不过，所有的*.so文件似乎都存在

user@Computer:~/Tools/cocotb-master/cocotb/libs$ ls
libcocotb.so            libcocotbvhpi_ius.so   libcocotbvpi_icarus.vpl   libcocotbvpi_vcs.so        libgpi.so

libcocotbvhpi_aldec.so  libcocotbvpi_ghdl.so   libcocotbvpi_modelsim.so  libgpilog.so

cocotb中有一个bug，现在应该修复了。请参阅https://github.com/cocotb/cocotb/pull/1606
