Ubuntu 14.04 - gnat downloaded from libre.adacore vs apt-get

[RasikaSrinivasan]

all

i had to reimage my Ubuntu system to 14.04. I got gnat installed successfully.

gnatmake --version

reports 4.6

I would like to install the ARM version of gnat. When I install the version I download from the libre.Adacore site, The executables such as gps_exe do not "run". The shell says "No such file or directory". Even though the PATH variable is updated correctly and which gps_exe correctly identifies the executable correctly.

I suspect some ld conflict. 

Can I install gps through the Ubuntu standard software install mechanism?
Can I install the ARM version of gnat through the Ubuntu standard software install mechanism?
Can I have the ARM cross and the Linux versions running in parallel?

any pointers would be appreciated.

thanks, srini

Just a comment to this point "no such file or directory" while the file is there:

this is tipical for an executable with wrong architecture. This would happen for
example with a 32 bit binary executed on a 64 bit system without the compatible
32bit libs installed.

I don't know if this also happens with a ARM executable on intel/amd cpus.

You probably can't get the AdaCore GNAT software to install using the standard
Ubuntu procedure (apt-get and such).  See my detailed installation instructions
from the post to this web site on about Oct. 17.

Oops - should be Oct. 19 (10/19/2014).

Yes: aptitude install gnat-gps.

No.  No Ada cross-ucompiler for ARM has been packaged for Debian yet,
therefore not for derivatives like Ubuntu either.

> Can I have the ARM cross and the Linux versions running in parallel?

Yes.  For this you must install the Ada cross-compiler from AdaCore, in
parallel to the native gnat-4.6 compiler from Ubuntu.  You can use the
gnat-gps IDE from Ubuntu and configure it to invoke the arm
cross-compiler from AdaCore.

Is this a cross compiler?

If so, do you see anything suspicious in the
output of ldd run on the compiler executables?
