CMake Configuration Error
```
Error:
CMake Error at src/CMakeLists.txt:202 (add_library):
Cannot find source file:
/home/cbadmin/bom-parts/madlib/src/ports/cloudberry/dbconnector/Compatibility.hpp
```
Tried extensions .c .C .c++ .cc .cpp .cxx .cu .mpp .m .M .mm .ixx .cppm .h
.hh .h++ .hm .hpp .hxx .in .txx .f .F .for .f77 .f90 .f95 .f03 .hip .ispc
CMake Error at src/CMakeLists.txt:202 (add_library):
No SOURCES given to target: madlib_cloudberry_3
CMake Generate step failed. Build files cannot be regenerated correctly.
Location: Referenced in src/ports/cloudberry/CMakeLists.txt:61
Observation: The directory
/home/cbadmin/bom-parts/madlib/src/ports/cloudberry/dbconnector/ does not
exist, while the equivalent Greenplum
directory does exist at
/home/cbadmin/bom-parts/madlib/src/ports/greenplum/dbconnector/ containing:
- Compatibility.hpp
- dbconnector.hpp
---
Additional Build Errors (After Manual Directory Creation)
After manually creating the missing directory and copying files from
Greenplum, cmake succeeded but compilation fails with multiple errors in
Compatibility.hpp:
1. AggState API change: aggcontext member doesn't exist (suggests
aggcontexts)
2. WindowState renamed: T_WindowState not declared (suggests
T_WindowAggState)
3. Missing function: format_procedure not declared
4. Function conflict: Ambiguous AggCheckCallContext - both the compatibility
shim and PostgreSQL's native version exist
These errors indicate API differences between Greenplum's PostgreSQL base
and Cloudberry's PostgreSQL base.
