It seems to look for libs via absolute path. Right?
Oh, did you mean set this path [LDFLAGS="-Wl,-rpath,$PREFIX/lib"]
as relative path ?
If so...but i don't know how to set, could you pls kindly help me ?

Sorry, I don't know.  Read through the GCC manual [1] for the version
of GCC you want to use, it should say how to.

Dear Andrew,

1, You can get android's C toolchain there:

git clone https://android.googlesource.com/platform/prebuilt
/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/
(FROM: http://source.android.com/source/building-kernels.html)

2, >try building your toolchain with relative paths
HOW to?
(You can modify my script direct)

Thanks! I question Google's need for putting compiled gcc versions in a
git tree, but that's a separate debate :)

It looks like Google's Android gcc, so long as you move the entire
'prebuilt/linux-x86/toolchain/$ARCH' directory structure around as one
unit, is using relative paths for their GCC.  Their gcc, for example,
looks for libs in '../lib/gcc/$ARCH/$GCC_VERSION', relative to the gcc
binary.

If you build your GCC like Google does, you should get the same
effect.  CLFS doesn't have you do it the Google way, CLFS is more like
how Emdebian's cross compilers are built, with explicit paths to find
libs.  I don't know how to tell you how to do it the Google way, but
the GCC manuals should.

OK, so that output isn't where gcc searches for things.  It's just the
info provided when gcc was configured and built.  The actual search

Better switches to see where gcc looks for things is
'-print-search-dirs' which will show you where gcc will look.

DJ Lucas <dj< at >linuxfromscratch.org> wrote:


I'd agree with you, except (especially) on a multi-arch system (or
anything with cross compilers and cross libs), the shared libs for the
target arch are going to be in rather different places than the shared
libs for the host arch. I'm not sure LD_LIBRARY_PATH will do much for
you here.

On my Debian system, I have arm cross compilers from Emdebian and native
x86_64 compiler from Debian Squeeze, and I don't have LD_LIBRARY_PATH
even set (echo $LD_LIBRARY_PATH comes back empty).  I have no problem
cross compiling or native compiling.

For example, output from my armel GCC shows where it expects includes
and libs:

andrew< at >bradford:~/calc/linux$ arm-linux-gnueabi-gcc -v
Target: arm-linux-gnueabi
Configured with: <snip>
--libdir=/usr/lib --includedir=/usr/arm-linux-gnueabi/include
--build=x86_64-linux-gnu --host=x86_64-linux-gnu
--target=arm-linux-gnueabi --with-headers=/usr/arm-linux-gnueabi/include
--with-libs=/usr/arm-linux-gnueabi/lib

Generally, my understanding is, for sane make systems, setting
CROSS_COMPILE= or similar will get make to use the right GCC.  Then GCC
relies upon it's internal configuration in order to find the
includes and libraries.  I'm not sure how LD_LIBRARY_PATH plays with
cross compilers... Probably some interesting reading could nail this
down, though.  Now I want to find out...

Good.


I'm not familiar with Android's C toolchain. Can you point me towards
where I can get one already compiled like you are using? I'm curious to
see what their GCC setup is.  That might shed some light.  I don't have
time to build yet another toolchain, thus the ask for a binary, I can
get the info I want out of a binary.


I believe you should be able to compile the Linux kernel even if GCC
can't find any of the libraries.  It's a kernel and all "library" calls
made in it exist as source within it.  You don't need things like libc
or mpfr to build Linux.  It's everything that runs on Linux that
probably will want the libs.


For now, I'm going to chalk this one up to you should just keep your
toolchain where you built it.  Don't move it.

It's like if you go to the doctor complaining, "Every time I stab
myself in the face with this knife, it hurts."  The doctor will tell
you, "Stop stabbing yourself in the face with a knife!"

If you want, try building your toolchain with relative paths.  I've not
tried this, so no assurances it'll work, but that's the only easy way I
can think of to make a toolchain that doesn't mind being moved.  I'm
not sure if when building, the relative path to the libraries should be
in the context of the build dir or the resulting dir...

Re: HELP ME: issue about arm cross toolchain (cannot find gmp.so, mpfr.so...)

DJ Lucas — 2012-05-24T05:49:46

Unfortunately, I am not well versed in cross compilers (always relied on
the CodeSorcery scripts for arm), so this response could possibly be a
wild goose chase (but I think it's correct). I suspect you are looking
for LD_LIBRARY_PATH...at least that's what works on native compilers,
though I suspect the same with cross compilers since it runs native,
just the output is for different arch. If my guess is right, you'll want
something like the following in your working environment:

LD_LIBRARY_PATH="/home/sudolee/cross_toolchain/lib"
LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/home/sudolee/your/final/project/output/dir/rootfs/lib"
LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/home/sudolee/your/final/project/output/dir/rootfs/usr/lib"
export LD_LIBRARY_PATH

Add any additional library paths in your project anddrop that into a
shell script in your home dir. Execute it any time you intend to compile
for your project. If that turns out not to work, there should be
something similar for cross compilers I would think. The default runtime
search paths are different and are arch dependent. You'll probably want
to modify those in the source before you build your cross toolchain, but
LIBRARY_PATH and LD_PRELOAD _might_ make a crutch on the target if you
didn't do that at the beginning. Those same two variables are also
useful on the host if your toolchain is linked to a specific set of
libraries that does not include the default library search path
(/usr/lib64:/usr/lib:/lib64:/lib). Also beware of linker scripts that
might crop up (usually .so files with hard-coded paths) or .la files
(also with hard-coded paths).

Dear Andrew,

Thanks for your answer.
It works well after put it all back where it was as you said.

But I find some cross toolchains (e.g. cross toolchain in android source
code) could work well after change its path(anywhere).
This is the script i tested lasy night, it works well and finally succeed.
And i cross compile kernel3.0.23 a moment ago, it also works well.

If i change its path from "/home/sudolee/cross/cross_toolchain" to
"/home/sudolee/cross_toolchain/", this issue occured.
Pls check the log below.
-----log-----

linux-gnueabi/4.6.0/cc1:
error while loading shared libraries: libcloog.so.0: cannot open shared
object file: No such file or directory
---------------

i know this issue occured due to the path changed, but i want find a way to
avoid this.
Maybe compiling all the library as static could avoid this issue(all the
libaray set by disable-shared). But i
tried many times, build process will abort with some errors, the error log
list below:

you can tell each thing you are compiling where to find the libraries

To see this, if you run the gcc you built with the '-v' switch, it'll
tell you where it expects to find libraries.  Yours probably aren't

We need more information, specificly errorcodes.  Please paste whole 
build log (including error) here.  Make sure that you include 
everything.  My suggestion is to run make once, then run it again using 
2>&1 $LOGFILE so you don't include any successful compiling to keep the 
paste as small as possible.

Dear all,

I built arm cross toolchain using the script in attachment. And finally
succeed.
But I moved the toolchain from the dir (it was) to another one, e.g.
from "/home/sudolee/toolchain/cross_toolchain"
to "/home/sudolee/".
Then i compile my source code by new cross toolchain, but it cannot find
some *.so, e.g. gmp.so mpfr.so cloog.so...

Anybody know about this issue?
Could anybody kindly help me?

I search this error with google and find this guy have the same error with
me:

http://comments.gmane.org/gmane.linux.lfs.clfs.devel/1442

According thie url, I find the there are 3 solution to solve this problem:

1. using 64bit linux to compile
2. change the configure of gcc (--enable-shared --> --disble-shared)
3. patch the gcc4.4.1

I think the best solution is patch gcc4.4.1, but this "
http://quandary.cross-lfs.org/~animeloe/" is not exist.

Could you give me this patch or some advice to solve this problem?

thanks

Come onto #cross-lfs support on irc.freenode.net and ask nicely.

Sorry for the dumb question, but how do I create a Trac account
so that I can create a new ticket?

For final libc if you want to use fstack-protector-all   first build  
the libraries without that by adding build-programs=no in configrams,  
then directly build again with build-programs removed and add your  
CFLAGS for fstack-protector-all and whatever else.  That should work.  
Worked for Robert back in the day with his hardening builds!
