compile error when build megcc

[alanguo1234]

hi I get the latest source code, I build megcc source code as the user guide, the step as follows:

1. apt-get install cmake ninja-build 2./third_party/prepare.sh
2. cd megcc/compiler
3. mkdir build
4. cmake .. -G Ninja
5. ninja

the error log as below: ../tools/mgb-to-tinynn/mgb-to-tinynn.cpp:102:19: error: ‘kernel_exporter’ has not been declared export_cv_opr(kernel_exporter, dump_info->cv_impl); ^~~~~~~ ../tools/mgb-to-tinynn/mgb-to-tinynn.cpp:102:36: error: ‘dump_info’ has not been declared export_cv_opr(kernel_exporter, dump_info->cv_impl); ^~~~~ ../tools/mgb-to-tinynn/mgb-to-tinynn.cpp:102:45: error: expected ‘,’ or ‘...’ before ‘->’ token export_cv_opr(kernel_exporter, dump_info->cv_impl); ^~ ../tools/mgb-to-tinynn/mgb-to-tinynn.cpp:102:54: error: ISO C++ forbids declaration of ‘export_cv_opr’ with no type [-fpermissive] export_cv_opr(kernel_exporter, dump_info->cv_impl);
