gmb problem on rhel6

Today I've found another solution - replace "--with-libgmp-prefix" (which is wrong) with "--with-gmp" (which is right according to PPL docs) - that worked for me and now I can use PPL in version recommended for GCC - 0.11. I suggest that build scripts for linaro toolchain should be upgraded...

I've compiled the toolchain several times, solving dozens of problems, so feel free to ask (;

BTW - I'm compiling using my "normal" gcc (most recent), without installing specific version like in the description. If you do the same, make sure to update variables in build-common.sh. I have them like that:
BUILD=x86_64-linux-gnu
HOST_LINUX=x86_64-linux-gnu
HOST_MINGW=x86_64-w64-mingw32
HOST_MINGW_TOOL=x86_64-w64-mingw32

Unfortunately, this suggestions didn't solve my problem.
I changed --with-libgmp-prefix with --with-gmp in build-prerequisites.sh and still I have following problem, here you can see part ofconsole view.

I have just found that I make a mistake and put on one plate --with-gmp-prefix. When I changed that, I got similar proble, slightly different:

But the scripts search for GMP in toolchain build directory - something like build_linux/host_libs/usr/... (don't remember now), so installing that in your system probably won't help much...

Why can't you try to replace PPL with 0.12.1 in toolchain src dir and updating version number in build-common.sh? That's all it takes to use newer PPL.

4\/3!!

I suppose because of this:

[savi_ne@ts gcc-arm-none-eabi-4_6-2012q2-20120614]$ sudo yum install ppl
Loaded plugins: refresh-packagekit, rhnplugin
Setting up Install Process

Nothing to do

I think the main problem is that I am not so involved in using linux.

If you only use the toolchain on the build system, you can use the gmp from your system, i.e. remove the build for gmp.

Does this mean that I should comment his in build-prerequisites.sh:

echo Task [1-1] /$HOST_LINUX/gmp/
rm -rf $BUILDDIR_LINUX/gmp && mkdir -p $BUILDDIR_LINUX/gmp
pushd $BUILDDIR_LINUX/gmp

CPPFLAGS="-fexceptions" $SRCDIR/$GMP/configure --build=$BUILD \
    --host=$HOST_LINUX \
    --prefix=$BUILDDIR_LINUX/host-libs/usr \
    --enable-cxx \
    --disable-shared \
    --disable-nls

make -j$JOBS
make install
#make check
popd

?

Yes, but you'll need to supply proper paths to GMP to other components that need it. Actually you probably don't need most of the libraries from the prerequisites if you have them on your system.

4\/3!!

OK, can you suggest me how to install proper version of ppl or how to supply proper paths to GMP?
I commented mentioned part and nothing happened again.

Hi Nemanja Savic,
Can you help me confirm whether the problem can be fixed by using the newly built gcc as in step 4?
You can just modify the environment files to add the path, for example on Ubuntu:
edit "~/.bashrc" by adding following code at the end of file:

export PATH=XXX:$PATH

in which XXX is the path where you installed the newly built GCC.

I think it's something similar for rhel6 system.
After that, please use following command to verify the newlib built GCC is in PATH:

$ which gcc

Hoping this help.

I built new gcc like few days ago, or I hope that it was successful build, cause it lasted for one hour or so.
I added new path as it was suggested.

[savi_ne@ts-070046nl native-gcc]$ export $PATH
bash: export: `/home/savi_ne/tools/native-gcc/target/bin:/home/savi_ne/tools/native-gcc/target/bin:/usr/lib64/qt-3.3/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/savi_ne/bin': not a valid identifier
[savi_ne@ts-070046nl native-gcc]$ which gcc
/usr/bin/gcc

Obviousely, something is wrong.

Ok, I managed to install properly native gcc:

[savi_ne@ts-070046nl ~]$ which gcc
~/tools/native-gcc/target/bin/gcc

Does this mean that my default gcc is nativ-gcc or not?
Is there any specific action for compiling arn tool chain using native-gcc or I should act as usual?

Regards

@chengbin

the problem vannot be solved using native-gcc. I still have the same problem.

Sorry I haven't tried the build process on rhel6, now I am not sure what the problem is.
Basically, in our release, GCC(version 4.6) requires GMP/MPFR/MPC/PPL/CLOOG.
You can refer to GCC document at http://gcc.gnu.org/install/prerequisites.html to see how to specify correct gmp package when configuring GCC.
After understanding the relations between these prerequisites and GCC, you can open config.log and check why it cannot find the correct version GMP.

NOTE, the GCC document is for GCC trunk, it requires ISL, rather than ppl as our release.

Hoping this can help.

But it's PPL that doesn't find GMP, not GCC... It's in the "build-prerequisites.sh" stage, not during final compilation of toolchain. That's the problem.

Yes, that is the problem. So, any new suggestions?

Somewhere is stated about installing first gmp, mpfr, mps and ppl with some proper configuration, and then installing GCC using previously installed tools.
Do you think that this is proper way?

You always do it this way, but that's not the problem anyway [; Try PPL 0.12.1 - when I tried some time ago it solved the problem you have. Now - when I build "natively" (so my PC is x86_64-... and I set BUILD and HOST variables in build-common.sh to this type) - it works with PPL 0.11, but when I try to do it non-natively (like specifying that HOST would be i686) it still fails. Fortunately I don't need 32-bit binary anyway (; Maybe you could try that too? If your PC and your OS is 64-bits you should specify these variables to be the same as your system, so x86_64-linux-gnu it I remember correctly.

4\/3!!

There is also another question (sorry for a lot of them):

In native gcc as you can see this path

~/tools/native-gcc/target/libexec/gcc/x86_64-unknown-linux-gnu/4.7.2/

There is no i686, can this be becuse of bad native-gcc installation?

Actually I was talking about compiling the toolchain with the "native compiler" of your system (the one from RHEL6), not compiling your own compiler. Try looking for that compiler in /usr, /bin or sth like that (sorry, don't know much about linux), and use it. It will probably be x86_64-unknown-linux-gnu too, and that's exactly what you should enter as BUILD and HOST_LINUX

I still haven't installed this tool under RHEL6. Any new suggestions?

Very sorry that we have no RHEL6 system, so no progress on this issue yet.
Is it possible for you to re-build the toolchain on other validated platforms?

Hi Nemanja,

I managed to set up a 64bit RHEL 6.2 system and can reproduce this issue. During the PPL configuration, a file named conftest.c will be generated and built to verify whether there are GMP head files and library files in current environment. So to successfully build this file, the PPL configuration process needs to know where to find those head files and library files. With option "--with-gmp-prefix=$BUILDDIR_LINUX/host-libs/usr", on 32bit system, a "/lib" will be appended to constitute a search patch. This works because we do install all files under this path. But on 64bit system, PPL will append "/lib64" to that path. Thus the GMP files can't be found. So the PPL configuration aborts on 64bit system. Unlike PPL, the other prerequisite libraries use "/lib" for both 64 and 32 bit systems, so they don't have this issue.

If use options like "--with-gmp=DIR" or "--with-gmp-build=DIR", PPL can only deduce library files from them, not the head files. So the build of conftest.c still fails.

To quick fix this issue, just specify the correct path to .h files in CXXFLAGS and CFLAGS, the path to .a files in LDFLAGS when configure PPL. In my system, I configure PPL with:

###############################################
echo Task [I-4] /$HOST_LINUX/ppl/
rm -rf $BUILDDIR_LINUX/ppl && mkdir -p $BUILDDIR_LINUX/ppl
pushd $BUILDDIR_LINUX/ppl

CFLAGS="-I$BUILDDIR_LINUX/host-libs/usr/include" \
CXXFLAGS="-I$BUILDDIR_LINUX/host-libs/usr/include" \
LDFLAGS="-L$BUILDDIR_LINUX/host-libs/usr/lib" \
$SRCDIR/$PPL/configure --build=$BUILD \
    --host=$HOST_LINUX \
    --target=$TARGET \
    --prefix=$BUILDDIR_LINUX/host-libs/usr \
    --disable-shared \
    --disable-nls \
    --enable-interfaces=c,c++ \
    --with-gmp-prefix=$BUILDDIR_LINUX/host-libs/usr

make
make install
popd
###############################################

The new option "--enable-interfaces=c,c++" is to prevent building PPL for JAVA. If JAVA isn't installed in your platform, this build will be disabled automatically.

Also please remember to update the --host and --build to something like:
BUILD=x86_64-linux-gnu
HOST_LINUX=x86_64-linux-gnu

With above changes, I can build the prerequisite libraries and toolchain on my 64bit RHEL 6.2 machine.

Hope those are helpful.

Hi all,

hm, I haven't been trying to install this for a two months or so now, so I have forgot about the things I was doing before. But this looks very promissing. Here I can only use RHEL and nothing else, that's the biggest problem, because otherwise I would install ubuntu and be in peace.

Since I have deleted everything I have to start again from scratch.

I have changed variables BUILD and HOST_LINUX.
In build-prerequisites.sh, do I have to comment installing gmp, mpfr and mpc and use them from my system, or I should install them as well?

Best regards and thank you
Nemanja

And also maybe this can be usefull for u to tell me what's wrong. i mean obviousely gmp libraries again, but maybe something else

Fortunatelly guys, it finally works thanks to Terry Guo. I read few times his post and realized the problem abput the folder, so I have just added following line before confiiguring ppl (except changing host and build variables as was stated above):

#################################

cp -R $BUILDDIR_LINUX/host-libs/usr/lib $BUILDDIR_LINUX/host-libs/usr/lib64

#################################

and it made my life easier.

Many thanks, and I hope that this will be helpful to the other people.
