[SOLVED] .libs/noncopyable.o' is incompatible with i386:x86-64 output

Aquarius_Girl · 04-19-2010, 06:10 AM

OpenSuse 11.2 (64 bit)

I installed libxml-2.18.2, Doing make gives me the following error:

Code:

collect2: ld terminated with signal 11 [Segmentation fault]
/usr/lib64/gcc/x86_64-suse-linux/4.4/../../../../x86_64-suse-linux/bin/ld: i386 architecture of input file `.libs/noncopyable.o' is incompatible with i386:x86-64 output

Any idea why i am getting this ? and what does this mean ?

Welcome to the world of 32/64 bit woes

try file /path/to/noncopyable.o

It seems to be expecting a 64 bit file. If you have a 32 bit one, that may or may not be good enough. The crash indicates it isn't good enough.
It could also be a lib for arm, sparc, macos, etc.

the best bet would be to build the library from source
I'm running 64bit slackware and have to install just about every thing from source
at this point in time (64bit distros are just now becoming common) the 64bit
speed boost is not yet free you need to put extra effort in to the system
like installing shared libraries from source

business_kid and rob.rice

Thanks to both of you for the valuable insights !

I shall try to re-install the package again after a few days, then i shall reply back to thread again !

What should i understand from this ?

How should i know whether the library is for 32 bit OS or a 64 bit OS ?

I downloaded the tar ball of that library then did:
./configure
make

Isn't this called installing from source, or I am getting it wrong ?

Aquarius_Girl · 04-30-2010, 07:13 AM

This error has been solved [though i failed to understand how]

I ran :

Code:

make clean
./configure
make
make install

Now there are no errors !

You never posted the results of the file command.

/Guessing
You _had_ a 32 bit lib; You built it from source and got a 64bit one. Either that, or there was a version conflict between some old version of that lib you downloaded and something else.
/End guessing

Stop worrying. Rule no 1 is
"If it ain't broke, don't fix it!

Actually i didn't know that file was a command:

Code:

anisha@linux-uitj:~>locate noncopyable.o
/home/anisha/tarBalls/libxml++-2.18.2/libxml++/.libs/noncopyable.o
/home/anisha/tarBalls/libxml++-2.18.2/libxml++/noncopyable.o
anisha@linux-uitj:~>file /home/anisha/tarBalls/libxml++-2.18.2/libxml++/noncopyable.o
/home/anisha/tarBalls/libxml++-2.18.2/libxml++/noncopyable.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped
anisha@linux-uitj:~>file /home/anisha/tarBalls/libxml++-2.18.2/libxml++/.libs/noncopyable.o
/home/anisha/tarBalls/libxml++-2.18.2/libxml++/.libs/noncopyable.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped

Now can you explain me what happened in detail and how to resolve such problems in future ?

business_kid · 05-04-2010, 03:21 AM

I did.

See my previous post under /Guessing

To paraphrase: You somehow installed a 32 bit lib on your 64 biot system and whatever needed it barfed. You installed from source, and the configure script has a look(runs uname [options] actually) and decides whether you are 32 or 64 bit and builds accordingly. You then installed this and it overwrote your 32 bit lib with a 64 bit one. Now you should close the thread, (Edit the first post/Advanced & edit subject & mark it solved) thank me and go away :-).

Thanks for the explanation.

Next time if you feel bored while explaining things to me, feel free to ignore my posts.

I didn't mean to come across that way. Sorry if I seemed rude.

I've been there, knowing the answer is staring me in the face, or that something weird has happened, and made it a bit further up the learning curve, that's all. I was being cheeky, and should have put a bigger smiley!
