Assume that we have a language called K. The source files *.k are compiled using a compiler called 'kc'. This project has a single source file 'file.k' and I want to use autotools for generating Makefiles. Automake fails to produce 'Makefile.in' complaining:
Can't call method "target_hook" on an undefined value at /usr/local/bin/automake line 1943. Software setup: automake 1.5 autoconf 2.52 perl 5.6.0 RedHat Linux (2.4.2-2 kernel) In my case the language was Fortran-90, but the error is generated for any unknown file extension, even if compilation rules for that language are provided in 'Makefile.am'. Any suggestions? Dmitry The setup follows: ******** configure.in ******************** dnl Process this file with autoconf to produce a configure script.
