Hi I am currently converting a heap of stuff from custom make system to
the GNU autotools, most things are really easy to convert however...
I have a couple of modules that use homegrown compilers to generate
multiple .cpp and .h files from specification files.
Here is the original make file.
----------------------------------------------------------------------
DICTIONARY := oiMsgs oiMsgGroups oiFields
-include sourcefiles
oimsg_src := $(SOURCE_FILES)
oimsg_hdr := $(HEADER_FILES)
LIBRARY := oimsg
INCLUDES := $(oimsg_hdr) OITypes.h OITypedefs.h
EXTRA_GENERATED := $(oimsg_src) $(oimsg_hdr)
EXPORT_INCLUDES=$(INCLUDES)
EXPORT_LIBRARIES=liboimsg.a
include bby.mk
---------------------------------------------------------------------------------------------
This is my attempt at an automake .am file.
COMPILER= ../src/oimsg
sourcefiles $(oimsg_src) $(oimsg_hdr): dict.stamp
dict.stamp:$(DICTIONARY) $(COMPILER)
mkdir -p tmp
cp $(DICTIONARY) tmp/
(cd tmp && ../$(COMPILER) $(DICTIONARY) && for i in *; do cmp -s $$i
../$$i || (echo Updating $$i ; mv $$i ../) ; do
ne)
touch dict.stamp
rm -rf tmp
CXXFLAGS = -Wall -O
$(COMPILER):
# Do nothing to stop stupid recursive rules applying
--------------------------------------------------------------------------------------------------------
The file 'sourcefiles' is also generated by the compiler and contains
declarations for SOURCE_FILES and HEADER_FILES with all the source and
header files the compiler generated in the appropriate variable.
Here is my attempt at getting this working with automake.
include $(top_srcdir)/../Make.include
OI_DICTIONARY = oiMsgs \
oiMsgGroups \
oiFields
OI_COMPILER = ../src/oimsg
sourcefiles:
mkdir -p tmp
cp $(OI_DICTIONARY) tmp/
(cd tmp && ../$(OI_COMPILER) $(OI_DICTIONARY) && for i in *; do cmp
-s $$i ../$$i || (echo Updating $$i ; mv $$i ../
) ; done)
touch dict.stamp
rm -rf tmp
lib_LTLIBRARIES = liboimsg.la
liboimsg_la_DEPENDENCIES = $(OI_DICTIONARY) \
$(OI_COMPILER) \
sourcefiles
liboimsg_la_SOURCES = $(wildcard *.cpp)
include_HEADERS = $(wildcard *.h)
The problem is that during a 'make install' all the headers are picked
up ok, during a make however none of the cpp files are being picked up
even if I have run the compiler myself so they are sitting in the
directory before make is run.
Can anyone offer any assistance with this? I'm not a make expert by any
means and I'm very new to the autotools, any help is greatly appreciated.
thanks.
Gary.
