[SOLVED] C++: ../x86_64-suse-linux/bin/ld: cannot find -lcmt

Aquarius_Girl · 03-28-2011, 03:57 AM

I was building a project which includes Qt and C++.

There were some errors related to the ogre package, which I resolved by following the instruction in the README file, now there is a new error:

Code:

/usr/lib64/gcc/x86_64-suse-linux/4.4/../../../../x86_64-suse-linux/bin/ld: cannot find -lcmt

I searched Google w.r.t -lcmt, couldn't find much.

Any ideas.

What compelled you to search for "-lcmt"; how about trying "libcmt.so"?

Does SuSe offer a package manager that can be used to look up if there is a package for libcmt-devel, or something similarly named?

Thanks for responding, DWhitney.

My absent mindedness, it happens sometimes

There must be some other name for the package, since after you wrote an eye opener post, I tried this:

Code:

linux-uitj:/home/anisha # cnf libcmt-devel
libcmt-devel: command not found

But, let me search further for the exact name.

I have searched Google now, the package name seems to be correct, but the suse repositories doesn't seem to recognize it.

There are random rpm's available, but let me report this to be moved to software section, it has nothing to do with programming. Let me see, if some one there knows about the rpm for suse.

There may not be a 64-bit version.

Aquarius_Girl · 03-28-2011, 06:06 AM

I couldn't locate even a 32 bit version, even putting libcmt doesn't result in anything from the suse repository search bar.

Hi Anisha.

I guess, you already know, that lcmt means libcmt.a or libcmt.so .
The available packages have libcmt.a, libcmt.so
wget http://apt.sw.be/redhat/el5/en/x86_6....rf.x86_64.rpm
wget http://apt.sw.be/redhat/el5/en/x86_6....rf.x86_64.rpm

Source package :
http://apt.sw.be/redhat/el5/en/source
wget http://apt.sw.be/redhat/el5/en/sourc...fc6.rf.src.rpm
cd libcmt-0.1.0/ && ./configure --prefix=/usr/ --libdir=/usr/lib64/
&& etc. etc.

You are the life saver, Knud.

Sometimes I search Google with my mental eyes closed.

Those packages have a redhat in the link path, you used to say that random packages don't work, I'll try out those and see if they work,

A big thanks to you again.

"Random" packages don't work ...

When you investigate, what the package is, and what it provides,
and may be run 'ldd <binary>' : Then it's not really a "random" any more.

If you choose a package, that was built with later libraries ( glibc ),
than the version(s), you have, then it will probably not work.

With your fourth link, I did:

Code:

sudo rpmbuild --rebuild libcmt-0.1.0-3.fc6.rf.src.rpm

It resulted in:

Code:

/usr/src/packages/BUILDROOT/libcmt-0.1.0-3.fc6.rf.x86_64/usr/lib/libcmt.a: should be in */lib64
error: Bad exit status from /var/tmp/rpm-tmp.u17avU (%install)


RPM build errors:
    InstallSourcePackage at: psm.c:232: Header V3 DSA signature: NOKEY, key ID 1aa78495
    Bad exit status from /var/tmp/rpm-tmp.u17avU (%install)

Does this mean I need to install .a file too? I don't want to messa round taking decisions on my own.

knudfl · 03-28-2011, 08:21 AM

My mistake : the file libcmt.so is in the package libcmt-0.1.0-3.el5.rf.x86_64.rpm.

( I have edited post # 7 ).

Then there is no reason to build the packages.
The errors : A typo in the file libcmt.spec, or caused by a different syntax.
( .spec files are usually not interchangeable between Suse / Fedora (RH) / Mandriva,
without edits. Usually you will be stopped at start.)
