g++ finds error in locale_facets.h

[Wolf-Ekkehard]

I thought I should be able to figure that out by myself, but I am beginning to pull my hair out over this...

I have Kubuntu 11.10 running on two 32-bit x86 machines. On one (a laptop) g++ (4.6.1) works fine. The other one I just converted recently from a dumped Windows box and put 11.10 on it. The latter one won't let me compile. I reduced the problem to the simplest form, i.e. the effects of the include tree of /usr/include/c++/4.6/ios:


#include <ios>

int main( int argc, char** argv )
{
;
}

When I compile on the faulty machine, I get the following output (on the laptop it compiles silently without error and exits):

I have diff-ed the output of g++ -v as well as the files locale_facets.h, basic_ios.h, and ios from both machines - they are all identical.

Can anybody shed some light on this for me, please?? How did I mess this up, and, more importantly, how do I fix it? I really don't want to turn my ten year old laptop into a compile server.....

[azzamite]

That just compiled in my box !

Did you install stuff like make and the development packages for libc6 libstdc++6 ?

My guess is that you're missing some -dev packages.

[Wolf-Ekkehard]

Nope - at least these two are all there. But it is a good point nonetheless: Which dev packages would not come with g++-4.6, qt4-dev-tools and kdevelop? I thought those basically should take care of all the dev packages I'd ever need. Wrong??

These are the packages I installed:


apt-get -y install g++
apt-get -y install kdevelop
apt-get -y install libcppunit-dev
apt-get -y install libcppunit-doc
apt-get -y install autoconf
apt-get -y install autoconf-doc
apt-get -y install libncurses-Sdev
apt-get -y install cmake
apt-get -y install lsb-qt4
apt-get -y install qt4-dev-tools
apt-get -y install libqt4-dev
apt-get -y install doxygen
apt-get -y install doxygen-doc
apt-get -y install doxygen-gui
apt-get -y install graphviz
apt-get -y install valgrind
apt-get -y install libc6-dbg
apt-get -y install kcachegrind
apt-get -y install alleyoop

[gsmanners]

You have libc6-dbg but not libc6-dev?

[Wolf-Ekkehard]

I have both - on both machines

[3Miro]

You should have the build-essential package installed (it pulls everything that you may need to compile stuff).

If this doesn't help, change the problem to:


//#include <ios>

int main( int argc, char** argv )
{
;
}

The error is in ios and should affect the rest.

[Wolf-Ekkehard]

yup - I have the build-essentials installed too.

If I take the include statement for ios out of the code, as you suggest, it compiles fine. But whenever I include <iostream> (which includes <ios> down the line), it barfs.

[gsmanners]

Weird. Works fine here.

[gsmanners]

That is a head-scratcher. I'd suspect some RAM problems or maybe a bad sector on the drive of that Wind'ohs box.

[Wolf-Ekkehard]

Well - hardware is always a possibility, I'll run some diagnostics - at least you made me feel less stupid :-)

[GeneralZod]

As a guess, I'd say you might be missing some header: it thinks isspace, etc are macros (like in C, but not in C++), which hints that it's looking for the C++ version of the header which contains this, not finding it, and #including the C version instead.

Try:



dpkg --listfiles libstdc++6-4.6-dev | xargs -n1 file | grep ERROR

and see if any errors are reported.

[Wolf-Ekkehard]

Smart idea!! Of course, I would prefer for it to report an error if it doesn't find the C++ version instead of silently including the C version - but that's just me...

I ran that, but no error was reported. Then I also dumped the output of xargs into a file and compared it with the output of the identical command run on my laptop - diff came out clean :-(

BTW - hw diagnostics came out clean too :-(

[gnometorule]

I'd uninstall everything related to gcc/c++, and then install merely the basics with build-essential. All I can think of is that a later lib overwrote some include path as the error is already in wchar.h etc. If it compiles after, carefully add additional libs.

[Zugzwang]

@OP: Would you mind posting the output of "g++ --version" here? Is is actually version 4.6, whose include files you are using according to your output?

[Wolf-Ekkehard]

No Problem. Here it is:

$ g++ --version

[Wolf-Ekkehard]

OK - I'd hate to mark this one "solved" as I could not find out root cause...

I uninstalled everything even remotely related to the C++ compiler and its libraries - no change when I got the build-essential package back. So I ended up re-installing 11.10 and all of my applications, which got rid of the problem - everything compiles fine now, as it does on any of my other machines.
