Exactly what it says: no previous prototype. A prototype in C is a declaration of function signature.

Look at this, as Sjoerd already pointed out: http://dev.monetdb.org/hg/MonetDB-extend/file/tip/reverse/reverse.c at lines 77 and 78

any ideas? thanks in advance.

No I did not. I did the same for just pure Monetdb version and it works. Here it does not, I can not really understand the difference between these two source versions.

Thanks a lot. I was using SP2 version and have not put anything in udf.h. I added entry in udf.h and it worked.

In addition, the exacly same code should behave identically with both the Jul2015 release branch and the pythonudf develpment branch --- provided you checked out both branches from the Mercurial repository.

In case you used the source tarball for the Jul2015-SP2 release, things are slightly different. Strict (for good reasons!) compiler options are by default only enabled with Mercurial source, but not with source tarball. You can (and should, if you develop code yourself) enable them also with source tarballs by running configure with --enable-strict .

NB, compiler warning and error not "nasty" but very helpful to write correct code.

I use two versions of Monetdb. 1 is PythonUDF and another Monetdb

11.21.13.
