# Makefile for GNAT for adabrowse
4
# This makefile assumes that the ASIS libraries are in
5
# ADA_INCLUDE_PATH and ADA_OBJECTS_PATH. If this is not
6
# the case, uncomment and edit the alternate definitions
7
# of GCC_OPTIONS and LD_OPTIONS below, and comment the now
10
# 05-APR-2002 TW Initial version
11
# 02-MAY-2002 TW Added 'nasty', changed the targets so they are macro refs.
12
# 08-MAY-2002 TW Changed the makefile so that it uses 'get_gcc' to figure
13
# out the name of the gcc used by GNAT.
14
# 08-JUN-2003 TW Added the automatic configuration stuff (with or without
15
# the project manager support).
16
# 20-NOV-2003 TW Correction for splitting path lists: Unix has ':' as the
17
# path separator, whereas Windows uses ';'!

#------------------------------------------------------------------------------
20
# It is assumed that the pathes to your ASIS installation are in your
21
# ADA_INCLUDE_PATH and ADA_OBJECTS_PATH!
23
# This makefile has become pretty complicated, mainly because of things
24
# which we figure out when the makefile is run:
26
# 1. We determine the compiler name used by gnatmake by default, and
27
# generate a package spec AD.Setup containing this name.
29
# This is so because on some Linux installations, the compiler to
30
# use for GNAT is not called "gcc" but "gnatgcc", and I want AdaBrowse
31
# to default to this name.
33
# To get the compiler's name and to create AD.Setup, we build a small
34
# utility program called get_gcc.
36
# 2. We figure out whether the GNAT sources are available. This is indicated
37
# by variable GNATSRC being set to the directory where the GNAT sources
38
# are. If this variable is set, and the directory actually contains the
39
# GNAT sources, then we try to configure AdaBrowse such that it uses the
40
# GNAT project manager.
42
# This is so because I don't want to distribute parts of the GNAT sources
43
# with AdaBrowse. The reason is that the project manager and some files
44
# it depends on differ between different GNAT versions, and furthermore
45
# I think ACT wouldn't like my distributing extracts from the 3.15p and
46
# 3.16a sources. Also, I'd have to add more and more extracts as new
47
# compiler versions appeared.
49
# So the way chosen here is actually simpler: the GNAT sources, which
50
# contain the project manager, are available from ACT, and users who
51
# want project manager support in AdaBrowse can get them and then just
52
# tell this makefile where they are. It isn't even necessary to try to
53
# build GNAT. The only requiremnet is that the sources are consistent
54
# with the GNAT and ASIS version used.
56
# To configure AdaBrowse, we build a utility program in subdirectory
57
# ./config and run it. The program then tries to build (using gnatmake)
58
# a dummy application using the project manager. If that succeeds, it
59
# configures AdaBrowse by generating two files ad-projects-impl.ads
60
# and ad-projects-impl-get_parent.adb. if building the dummy application
61
# failes, these files are set up such that AdaBrowse doesn't use the
62
# GNAT project manager.
64
# Only after these two configuration steps building of AdaBrowse proper
67
# And finally, this makefile is being complicated by the fact that the
68
# it has to work with the ancient GNU make 3.77 (distributed with GNAT 3.15p).
