Difference beetween windows binary execution and linux binary execution

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 ?!

Regards

Strange link error

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 
/home/duboism/Documents/These/Code/manips/rvg/manips/DB_Handler/objs/test_requestimage.ali 
-shared-libgcc -g -o 
/home/duboism/Documents/These/Code/manips/rvg/manips/DB_Handler/test_requestimage
/usr/lib/gcc/x86_64-linux-gnu/4.6/adalib//libapq.a(apq-postgresql-client.o): 
In function `apq__postgresql__client__host_name':
apq-postgresql-client.adb:(.text+0x6d0): undefined reference to `PQhost'

[Fwd: Almost finished porting gnat-4.6 to GNU/Hurd]

Hi, 

I'm forwarding here in hope to get some replies. No response yet from

Please Cc: me since I'm not subscribed to help-gnat.

Thanks!

Subject: Almost finished porting gnat-4.6 to GNU/Hurd

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:
Program received signal SIGSEGV, Segmentation fault.
0x01050b10 in
system__task_primitives__operations__specific__initializeXnn <at> plt
    () from /usr/lib/i386-gnu/libgnarl-4.6.so.1

gcc-Ada (gnat) for Solaris?

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

[patch, docs] GNAT socket server


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
Mike

GNAT GPL 2008 & VC++

Has anyone successfully built the ada_cpp example included with the GNAT
GPL 2008 (C:\GNAT\2008\share\examples\gprbuild\ada_cpp)?  On Windows.

VC++ Pragma Import

I have an GNAT GPL 2008 program that calls a VC++ procedure.  I receive a
"undefined reference" link error pointing to the VC++ routine name.

Does anyone know how to pragma import VC++ into GNAT 2008 GPL?

[patch, docs] Gnat distributed


I successfully installed Gnat ver 4.0.1 in Windows Vista, along with base
compiler and distributed compiler(gnatdist). 
I am trying now to compile a distributed programm: compilation and partition
creation is ok but while in linking phase an error occours, the message
looks like this: s-finimp is read-only and obsolete try to recompile.
Basically there are some dupplicated libraries used by 'gnatmake' and
'gnatdist' that have different contents (like s-finimp.ali).
I have tried all installation combinations (earlier versions) and it still
gives me this error. 
Any idea ?

problem with 64 bits binary

Hello,

I have a serious problem with gnat on solaris 9 :

I need to compile my code in 64bits mode.
So, in the gpr file, I added the m64 and RTS=rts-m64 options.
The RTS=rts-m64 don't seem to work, I had to export ADA_INCLUDE_PATH and ADA_OBJECTS_PATH to be able to link my soft.

Now, my code is compiled in 64 bits, and the executable linked. It is seen by the OS as a 64bits sparcv9 binary :

bash-2.05$ file factory 
factory:        ELF 64-bit MSB executable SPARCV9 Version 1, dynamically linked, not stripped

But when I launch the binary, it immediately crashes (core dump).

GDB told me it crashed on b~factory.adb, line 2152 :

Program received signal SIGSEGV, Segmentation fault.
0x0000000100434ea4 in main (argc=0, argv=(system.address) 0x0, envp=(system.address) 0x0) at b~factory.adb:2152
2152       function main

This line is : 

2152:   function main
2153:     (argc : Integer;
2154:      argv : System.Address;
2155:      envp : System.Address)
2156:      return Integer

How can a program crash on the main function header ???
Can the binary code be invalid ?

The 32 bit version executes fine on the same OS, compiled with the same version of gnat (GNAT Pro 5.04a1).

Thanks for your help !
