Hi All.
 I working on GHDL (An VHDL simulator) project for my purpose i installied
ghdl-0.29-2.143svn.4.fc16.src.rpm (contains ghdl 0.29 +gcc 4.3.4) using rpm
-i and rpmbuild -ba command successfully on fedora 16.After that a small
changes in one Ada program containg ghdl 0.29 folder,next i done make and
make install no error ,next try to execute ada program the it gave error 
"Ada compiler not installed on this system" After whatever on gcc it gave
below error.Attached config.log file
 "checking for C compiler default output file name... configure: error: C

Difference beetween windows binary execution and linux binaryexecution

David Barbassat — 2012-07-05T07:58:42

Hello,

I done a little program which take a file (text_io), analyze it and write some datas into files (manage by direct_io).

Under linux the time to execute the analyze is arround 20 seconds and under windows xp 32b : 2 minutes 10 !

Where is the bug ?!

Re: Strange link error

Mathieu Dubois — 2012-06-13T10:30:36

Hi,

I think I have found the problem. Thanls to the -v switch of gnatmake I 
realized that in the old directory apq.ali was found in the object 
directory of the project while it was not on the new directory (where 
the message was 'apq.ali is a read only library'). I think that the old 
directory contained a copy of apq.ali from the time it was installed on 
my local ADA_*_PATH...

Removing the file caused both project to fail at the same point.

I added the -lapq flag to the linker switch and it works now.

Hello,

I use gnatmake and a GPR file to build a project and I recently faced an 
error that I don't understand.
The problem arose when we moved some stuff in our SVN repository but I 
would be really surprised that this caused the problem.

The situation is as follow. The GPR project is located in a subdirectory 
(say foo/my_project/my_project.gpr). It uses other projects which are 
given by their relative path in with clauses. The project uses the APQ 
2.1 library which is installed in GCC path (apq.ads is in 
/usr/lib/gcc/x86_64-linux-gnu/4.6/rts-native/adainclude/, apq.ali is in 
/usr/lib/gcc/x86_64-linux-gnu/4.6/rts-native/adalib/apq.ali).

Due to the modifications on the repository I have indeed two copies of 
my_project: let's say that the current working is under foo/ and I have 
a unversionned copy under foo_tmp.

Under foo_tmp/my_project everything works fine (gnatmake -P 
my_project.gpr works nicely).
Under foo/my_project the same command leads to a link error:
gnatlink

Hello,

I have almost completed the cross-build and native-build of gnat-4.6.2
for GNU/Hurd. All debs does now compile and I can create packages
requiring gnat. One problem remains: Tuning the OS-interface routines.
Currently libraries and binaries build, but the binaries fail with
exception code: e.g.
./music123
raised STORAGE_ERROR : s-intman.adb:139 explicit raise

gdb music123 gives:

Re: gcc-Ada (gnat) for Solaris?

Jim Wise — 2012-03-01T00:19:34

Well, the main issue you'll hit is that you will need a running gnat to build gnat. 

If you use OpenCSW's gnat (it's available for i386 and sparc, IIRC), you should be able to bootstrap your own using the usual gcc bootstrap instructions. 

Without that, you'll need to follow a two-step dance, starting with gnat built for another platform:

A.) use gnat on platform $X to build a $X-to-Solaris gnat cross-compiler

B.) use that cross compiler to cross-build gnat for Solaris

And, optionally

C.) use your cross-built gnat to build gnat again, as a check

I've done this, long ago, when (not entirely successfully) porting gnat to a new platform, but since others have done the work, you might as well start there. 

In the case of OpenCSW, if you don't want to use their tooling, you could always download the actual package files and pkgadd them...

Hello Jim,

Thanks for the pointer. I would prefer to roll my own but I don't have the
know how. I should have phrased my question more carefully, I am asking if
there is anyone on the list who knows how to build gcc-Ada and if so if they
would be willing to help / guide me through the process. I have Solaris 10
running on 2 architectures and I'd like to build Ada on both of them. If I
am successfull I will try to host the packages somewhere.

There are a few sites like opencsw and I have heard good stuff about
them. The problem is most of them are creating package management systems 
and you have to use them to get the package. To get gcc4ada from opencsw I
would have to get prereqs that perhaps aren't and also install in their
selected paths as far as I know. I would like to be able to build generic
packages that can install in user chosen locations and not have to use a
package manager with someone else's ideas of prereqs and what should or
shouldn't be in a package. Solaris is especially delicate in th

Re: gcc-Ada (gnat) for Solaris?

Jim Wise — 2012-02-28T18:14:00

Yes. The OpenCSW package repo for Solaris includes packages for gnat.  See:

    http://www.opencsw.org/

and the "gcc4ada" package in particular.

Hello gents. Does anyone have the know-how to build gcc-Ada on Solaris? I
have SPARC and Intel boxes running Solaris 10 and I cannot find a good build
for either of them. I am looking for the LGPL version btw, not GNAT which
Libre Adacore does not offer at any rate for these platforms. TIA

Since you are using GNAT, you could use the GNAT.Sockets package.

I am new to Ada and GNAT.  I have to send data between a Java app and an Ada
app. I'm looking for an Ada server that can receive and send a byte stream.
I can't find any examples. If someone could point me to one I would
appreciated it.

Thanks in advance
