GNU doesn't seem to recognize libstdc++

Hi!

Just installed debian and got following problem: When trying to compile a simple program that uses some aspects of the std-lib (like vectors, strings and so on), I get following error messages on linking:

Code:

I am using gcc version 4.02. "g++ -v -H" gives

Code:

Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v --enable-languages=c,c++,java,f95,objc,ada,treelang --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --program-suffix=-4.0 --enable-__cxa_atexit --enable-libstdcxx-allocator=mt --enable-clocale=gnu --enable-libstdcxx-debug --enable-java-gc=boehm --enable-java-awt=gtk --enable-gtk-cairo --with-java-home=/usr/lib/jvm/java-1.4.2-gcj-4.0-1.4.2.0/jre --enable-mpfr --disable-werror --enable-checking=release i486-linux-gnu
Thread model: posix
gcc version 4.0.2 (Debian 4.0.2-2)

Does anyone knows what's wrong? (the app compiled just fine on my old slackware 10.1)

Thanx

As far as I can see you just forgot to tell the compiler
where to find the library... there's no -L statment.

Cheers,
Tink

MasterOfTheWind · 10-16-2005, 05:32 AM

Well, I've tried that too. I've also tried to link the library directly, like

Code:

g++ /usr/lib/libstdc++-.so.5 main.o some_obj.o -o prog

And that of course didn't help either... so I'm rather clueless about what's really going on here

Tinkster · 10-16-2005, 12:16 PM

Code:

g++ -L/usr/lib -lstdc++ -lm -O3 -ffast-math -Wall -I. main.o utils.o vector.o color.o matrix.o transform.o shape.o sphere.o -o iray

should work...

Cheers,
Tink

MasterOfTheWind · 10-16-2005, 12:36 PM

well, thanks for your suggestion :) I tried it, but I am still not able to compile my raytracer on debian sid. I'm getting a new kind of output now, though:

EDIT:
But now I noticed something strange: sometimes apt-get complains about a missing version of GLIBCXX when installing some deb-files:

Code:

update-menus: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.6' not found (required by update-menus)

I haven't seen that one before... so where is this reference pointing to? what kind of library should I install or re-install? libc? I thought that everything was updated all right... Shouldn't have switched to Debian :( My Slackware was fine enough. What do they say? Don't fix what ain't broken?

Harmaa Kettu · 10-16-2005, 12:51 PM

Looks like you have a version conflict. libstdc++.so.5 is for gcc 3.3 or older, gcc 3.4 and 4.0 use libstdc++.so.6

MasterOfTheWind · 10-16-2005, 01:23 PM

Oh yes, of course you are right! Compilation works with g++-3.3! Thanks a lot!

Though I still can't understand one thing: I have installed libstdc++ 5 and 6 while I also have g++ of versions 2.95, 3.3, 3.4 and 4.0. Don't ask how they ended up on my system, 'cause I can't recall installing them

(does debian install them by default or something?? but c'mon... 4 versions??). Well, anyway, it's all right that g++ 2.95 and 2.33 choose libstdc++ 5 instead of libstdc++ 6, but why do g++ 3.4 and 4.0 automatically use that same version (libstdc++ 5)? Is there any way to make them aware that the libstdc++ 6 is also installed?
