1 # This is the Unix/NT makefile used to build an alternate GNAT run-time.
2 # Note that no files in the original GNAT library dirctory will be
3 # modified by this procedure
5 # This Makefile requires Gnu make.
6 # Here is how to use this Makefile
8 # 1. Create a new directory (say adalib)
12 # 2. Copy this Makefile from the standard Adalib directory, e.g.
13 # $ cp /usr/local/gnat/lib/gcc-lib/<target>/2.8.1/adalib/Makefile.adalib .
15 # 3. If needed (e.g for pragma Normalize_Scalars), create a gnat.adc
16 # containing the configuration pragmas you want to use to build the library
17 # e.g. $ echo pragma Normalize_Scalars; > gnat.adc
18 # Note that this step is usually not needed, and most pragmas are not
19 # relevant to the GNAT run time.
21 # 4. Determine the values of the following MACROS
22 # ROOT (location of GNAT installation, e.g /usr/local)
24 # CFLAGS (back end compilation flags such as -g -O2)
25 # ADAFLAGS (front end compilation flags such as -gnatpgn)
26 # *beware* the minimum value for this MACRO is -gnatpg
27 # for proper compilation of the GNAT library
28 # 5a. If you are using a native compile, call make
29 # e.g. $ make -f Makefile.adalib ROOT=/usr/local CFLAGS="-g -O0"
31 # 5b. If you are using a cross compiler, you need to define two additional
33 # CC (name of the cross compiler)
34 # AR (name of the cross ar)
36 # e.g. $ make -f Makefile.adalib ROOT=/opt/gnu/gnat \
37 # CFLAGS="-O2 -g -I/usr/wind/target/h" CC=powerpc-wrs-vxworks-gcc \
40 # 6. put this new library on your Object PATH where you want to use it
41 # in place of the original one. This can be achieved for instance by
42 # updating the value of the environment variable ADA_OBJECTS_PATH
