trying to compile gnat

trying to compile gnat

[Schüle Daniel]

Hello

I am failing to compile gnat
the compilation goes fine but no gnatmake is generated
I was trying different gcc releases

gcc-3.2.tar.bz2
gcc-3.3.4.tar.bz2
gcc-3.4.0.tar.bz2
gcc-4.1.1.tar.bz2

tar xjf gcc-4.1.1.tar.bz2
cd gcc-4.1.1
./configure --prefix=/myLocation --enable-languages=c,c++,ada

also I tried to compile from parts, eg

gcc-4.1.1
gcc-ada-4.1.1.tar.bz2
gcc-core-4.1.1.tar.bz2
gcc-g++-4.1.1.tar.bz2
gcc-testsuite-4.1.1.tar.bz2

cd gcc-4.1.1
./configure --prefix=/myLocation --enable-languages=c,c++,ada

I am somewhat confused, gcc and g++ are genereated and
I can compile with them, so what's wrong with ada?

Regards, Daniel

Have you read the documentation?  It clearly says you must not build
in the directory containing the sources.  You must do:

$ mkdir gcc-4.1.1.o; cd gcc-4.1.1.o
$ ../gcc-4.1.1/configure --prefix=/myLocation --enable-languages=c,c++,ada
$ make bootstrap

Do you have a previous version of GNAT installed?  Since GNAT is
written in Ada, you need an Ada compiler to bootstrap it.

What "make" command do you use, after the configure?  It should be
"make bootstrap" or "make bootstrap-lean".

The GNAT tools (gnatmake etc) should then normally appear in the gcc
subdirectory.

no, I don't have GNAT installed, so I guess I am experiencing
egg chicken problem.
Is there no C written version of Ada compiler?

make bootstrap

no gnatmake on my system

thx, I will look for solutions

You also got some other good advice...But here is some more

1) You appear to be configuring within the source directory. This is not 
the recommended way of doing the build
2) There may very well be language and/or target specific requirements 
you need to follow. Read the notes at gcc.gnu.org
3) Use something prebuilt

What is your host os?

Suggested reading:

Mind you: The texts are old and with newer gcc's compiling becomes easier
(i.E. a lot of the --enable- options are now default and "make -C gcc
gnatlib-shared gnattools;" is not needed any more.

If you like some newer script files you can download them form The GNU Ada
Project:

http://svn.sourceforge.net/viewcvs.cgi/gnuada/trunk/rpm/SPECS/
http://svn.sourceforge.net/viewcvs.cgi/gnuada/trunk/tar/configure/

Those scripts are up to date for the most current gcc sources. I would also
invite you to join The GNU Ada Project [1]. The project if open for all
operating system.

You can download an Ada compiler from the following sites:

http://gnuada.sourceforge.net
https://libre2.adacore.com/

If you can't find a compiler for the platform you want to use then you will
need to cross compile.

Ok, this is where I am now

I have those dirs and files

build
gcc-4.1.1
gcc-ada-4.1.1.tar.bz2
gcc-core-4.1.1.tar.bz2
gcc-g++-4.1.1.tar.bz2
gcc-testsuite-4.1.1.tar.bz2

cd build

../gcc-4.1.1/configure --prefix=/pool/inst --enable-bootstrap 
--enable-languages=c,c++,ada
creating cache ./config.cache

configure: error:
The following requested languages could not be built: ada
Recognised languages are: c,ada,c++,obj-c++,treelang

ok, configure say no Ada installed
but the following works

root@mond---[21:01:48]---/pool/software2/gcc/new/build # gnatmake 					 
/pool/PROG/ada/1/main.adb
gnatgcc -c -I/pool/PROG/ada/1/ -I- /pool/PROG/ada/1/main.adb
gnatbind -x main.ali
gnatlink main.ali

it compiles

root@mond---[21:02:26]---/pool/software2/gcc/new/build # 
/pool/PROG/ada/1/main
begin
         200
end

and executes

this last step was not working yesterday
I installed gnat binaries and set PATH accordingly
I can call gnatmake and build ELF executables

What am I missing now?
Any help approciated.

Regards, Daniel

Looks like you are running one of those GNAT distributions where the 
compiler driver for gnat is gnatgcc instead of just plain old gcc. This 
has caused more problems with builds like this. perhaps you can do 
something with export CC=gnatgcc before the configure. The basic problem 
is that (I think) configure does not know how to find gnatgcc, it is 
looking for a gcc that knows Ada.

What host OS is this?

thank you a lot
it solved the problem
