Hai Yannis, Thanks for using MonetDB. Unfortunately, the MonetDB dev. team is no longer maintaining the JIT C UDF feature. To extend MonetDB with your own C functions, please see information and examples in this repo instead: https://dev.monetdb.org/hg/MonetDB-extend The MonetDB dev. team will keep maintaining this repo. If you encounter any problems there, please let us know. Best regards, Jennie

Hi,

I have an issue with C udfs. While most of the examples at https://www.monetdb.org/blog/JIT_C_C%252B%252B_UDFs_in_MonetDB run without problem, the example with SNAPPY does not run. It seems that linking, and includes work but if I call a function from the external library it fails with “write error on stream” The same happens also with other external libraries. My version is v11.37.11. Is there any idea for this issue?
