The main `mk/boilerplate.mk' file

If you look at `$(FPTOOLS_TOP)/mk/boilerplate.mk' you will find that it consists of the following sections, each held in a separate file:

`config.mk'

is the build configuration file we discussed at length in Section See section Getting the build you want.

`paths.mk'

defines `make' variables for pathnames and file lists. In particular, it gives definitions for:

`SRCS':

all source files in the current directory.

`HS_SRCS':

all Haskell source files in the current directory. It is derived from `$(SRCS)', so if you override `SRCS' with a new value `HS_SRCS' will follow suit.

`C_SRCS':

similarly for C source files.

`HS_OBJS':

the `.o' files derived from `$(HS_SRCS)'.

`C_OBJS':

similarly for `$(C_SRCS)'.

`OBJS':

the concatenation of `$(HS_OBJS)' and `$(C_OBJS)'.

Any or all of these definitions can easily be overriden by giving new definitions in your `Makefile'. For example, if there are things in the current directory that look like source files but aren't, then you'll need to set `SRCS' manually in your `Makefile'. The other definitions will then work from this new definition. What, exactly, does `paths.mk' consider a "source file" to be. It's based the file's suffix (e.g. `.hs', `.lhs', `.c', `.lc', etc), but this is the kind of detail that changes more rapidly, so rather than enumerate the source suffices here the best thing to do is to look in `paths.mk'.

`opts.mk'

defines `make' variables for option strings to pass to each program. For example, it defines `HC_OPTS', the option strings to pass to the Haskell compiler. See section See section Pattern rules and options.

`suffix.mk'

defines standard pattern rules -- see section See section Pattern rules and options
