Hello,
I recently built a GCC Ada cross-compiler for the PowerPC64 architecture using crosstool-ng. I can compile my Ada programs fine using powerpc64-e6500-linux-gnu-gnatmake but I have been unable to build with gprbuild and appropriate project files. I have traced this down to an issue with gprconfig not recognizing my compiler.
When I run gprconfig --show-targets
I get:
arm-linux-gnueabihf (Raspberry Pi2 Cross Compiler downloaded from Adacores website)
x86_64-linux-gnu
But I don't see powerpc64-e6500-linux-gnu even though the compiler executable is in my path. Does anyone know what the issue might be?
Thanks,
Zack

What about:
gprconfig --config Ada,,,<compiler-bin-path>,<compiler-name-if-not-gcc>

I think that gprconfig's compiler description file (at
$prefix/share/gprconfig/compilers.xml) doesn't recognise your target.
You could edit that file directly; might be better to start by writing a
description just for your compiler, starting just from the GNAT section
at about line 687,
<?xml version="1.0" ?>
<gprconfig>
<compiler_description>
<name>GNAT-PPC64</name>
<executable prefix="1">(powerpc64-e6500-linux-gnu-)?gnatmake</executable>
<version>
<external>${PREFIX}gnatls -v --version</external>
<grep regexp="^GNATLS.+?(\d+(\.\d+)?)" group="1"></grep>
</version>
<languages>Ada</languages>
<variable name="gcc_version">
<external>${PREFIX}gcc -v</external>
<grep regexp="^[-\w]*gcc \S+ (\S+)" group="1"></grep>
</variable>
<runtimes default="default,kernel,native">
<directory group="default" >\.\./lib/gcc(-lib)?/$TARGET/$gcc_version/adalib/</directory>
<directory group="default" contents="^rts-">\.\./lib/gcc(-lib)?/$TARGET/$gcc_version/ada_object_path</directory>
<directory group="2" >\.\./lib/gcc(-lib)?/$TARGET/$gcc_version/rts-(.*)/adalib/</directory>
<directory group="1" >\.\./$TARGET/lib/gnat/(.*)/adalib/</directory>
</runtimes>
<target>
<external>${PREFIX}gcc -dumpmachine</external>
<grep regexp="[^\r\n]+"></grep>
</target>
</compiler_description>
</gprconfig>
(not sure you need all of the <runtimes/> section) and put this in
x-compilers.xml alongside the original compilers.xml (or locally, using
the gprbuild --db switch).
You'll still need to specify --target=powerpc64-e6500-linux-gnu on the
command line, or for Target use "powerpc64-e6500-linux-gnu"; in your
GPR.
If this works, you'll probably want to add sections for C, C++, ASM.

Thanks, I was able to edit the existing GNAT line to support powerpc64-linux as a target. Hopefully I will be able to get C and C++ building correctly with gprbuild.

I seem to be having trouble getting my hello world C++ program to compile with gprbuild. I think it is trying to use the x86_64 version of "ar". Below is my output from gprbuild with the "-v" flag.
gprbuild --target=powerpc64-e6500-linux-gnu -v -d -P/project/hello_world_cpp/hello_world_cpp.gpr -XADA_DIALECT=Ada_2012 -XARCHITECTURE=PowerPC64_Linux -XBUILD_FLAGS=Optimize -XELABORATION_CHECKS=Static -XCOMPILER_MULTIPROCESS=8 -XDEBUG_TARGET=local hello_world.cpp -s -j6

I have tried adding
PowerPC64_Linux_Archiver := "powerpc64-e6500-linux-gnu-ar";
PowerPC64_Linux_Archive_Indexer := "powerpc64-e6500-linux-gnu-ranlib";
for Archive_Builder use (PowerPC64_Linux_Archiver, "cr");
for Archive_Indexer use (PowerPC64_Linux_Archive_Indexer);
but that does not resolve my issue. Does anyone have an idea what I am doing wrong?
Thanks,
Zack

I confirmed what the issue is, but I am not sure how to fix it. Basically, the wrong "ar" and "ranlib" executables are being called by gprbuild. I am a little stumped how to fix this one (I already tried Archive_Builder and Archive_Indexer attributes, but if I run the 3 commands on the command line with the correct ar and ranlib, I get a correct executable.
1.) powerpc64-e6500-linux-gnu-ar cr libhello_world_cpp.a /project/hello_world_cpp/hello_world.o
2.) powerpc64-e6500-linux-gnu-ar cr libhello_world_cpp.a /project/hello_world_cpp/hello_world.o

Ok, I finally got it working, I needed to edit linker.xml in shared/gprconfig directory.

BTW, when you compile and build, do you set ENV_PREFIX environment
variable to the target system root?

Good!
(thanks for bottom-posting: but to help those of us who use older

I do not set env_prefix. The compilers I builts for raspberrypi3 and powerpc64 appear to work fine, but I have not attempted to run ACATS on it yet.

It hit me once. When the ENV_PREFIX is not set, I just had pushed needed
libraries to the GNAT lib directory, the things were compiled OK, but
there popped subtle errors upon binding and linking, not in hello-world,
in the real size project. I don't know the exact reason, AdaCore guys
told me to set PREFIX and after that everything went perfect.

Thanks, I had that issue with ENV_PREFIX when testing out a GPL cross-compiler built by Adacore. I did not need the ENV_PREFIX when building GCC 5.3 with crosstool-ng.
