Probs: include in esql-c

How can we include header-files from another directory in esql-c? We divided our project into several subdirectories top I +--------+------+------+ gen inf40 incl server In the "inf40"-subdir are the esql-c files. The "incl"-subdir should be the place for all include-files. So far we couldn't get it to work with our esql-specific include-files (structure-definitions for database-tables and so on). As a workaround we linked these include-files into the inf40-subdir. Is there really no way to leave database-specific-include-files (what a word ?) in the "incl"-subdir and include them from there. Any help appreciated Klaus Rehm c0922@rrzc1.rz.uni-regensburg.de
