[Boost-users] "template with C linkage"

[Chris Coleman]

Hi,

I'm struggling with Boost (1.32) on Solaris 8 at the moment - I do not
have root access to the machine.

The default compiler is gcc-2.95, and so has no <ostream> <locale> etc
so the -sTOOLS=gcc toolset won't work. I then thought that the solution
would be to install STLPort, but can't get this to build cleanly.

Since then I have discovered that there is another version of gcc
(gcc-3.2) hidden in /opt/sfw/gcc-3.2. With this I then built the boost
libraries again, and installed them with the line:

bjam "--prefix=/staff/cqc/ -sGCC_ROOT_DIRECTORY=/opt/sfw/gcc-3.2
-sTOOLS=gcc" install

This seemed to work fine with no problems at all. I then moved the
headers, and the libs to the approprite places, and set about compiling
my project.

The result below is repeated many many times about various files:

/opt/sfw/gcc-3.2/bin/gcc -DHAVE_CONFIG_H -I. -I. -I.. -D_REENTRANT
-c -o zz_broker.o `test -f zz_broker.cpp || echo './'`zz_broker.cpp

linkage
/opt/sfw/gcc-3.2/include/c++/3.2/bits/stl_relops.h:130: template with C
linkage

I have searched the list archives and googled around quite alot, but
can't seem to find any info.

Any help will be greatly recieved,
Cheers
Chris

Do you perhaps have extern "C" block still open before you include
<boost/smart_ptr.hpp>? I get identical errors compiling the following
test program:

extern "C" {
#include <boost/shared_ptr.hpp>
}

Does the same problem happen with the following C++ file?

#include <utility>
int main() {}

If so, it's not a boost problem.

I have only one extern "C" {} block in the whole code. Its job is to
create a wrapper that allows a member function to be used as a pointer
to the pthread_create() function. I have checked that it is closed
properly. eg:

extern "C" {
void *ThreadStartup(void *);
}

The top of the file looks like:

#ifndef ZZ_BROKER_H
#define ZZ_BROKER_H

#ifdef HAVE_CONFIG_H
#include <config.h>
#endif

#include <iostream>
#include <pthread.h>
#include <boost/smart_ptr.hpp>

...
...


The code compiles fine under gcc-linux (gentoo, mandrake), mingw,
cygwin, its just Solaris thats causing problems. I'm not sure if this
is due to it being the non-standard install of gcc or not, or whether it
is a problem with the way I build boost etc.

Chris

The above code seems to compile without problem on the solaris box:

marian$ cat test.cpp
#include <utility>
int main() {}
marian$ /opt/sfw/gcc-3.2/bin/g++ test.cpp
marian$

I think you want `/opt/sfw/gcc-3.2/bin/g++`.

Hi,

Yeah - I noticed that after my 1st post. I was originally using:

CXX=/opt/sfw/gcc-3.2/bin/g++ ./configure && make

And tried gcc as a kind of desparate blind hope, but to no avail...

Sorry I should have added that to my previous post.

Cheers
Chris

I have the same problem on Mac OS X powerpc G4, trying to use boost_1_32_0.
Did you come up with a solution?

I've ungoogled some related info about NO_IMPLICIT_EXTERN_C flag, but have not
been able to resolve the issue.
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15834).
I'm completely baffled after two days of doing nothing but uncuccessfully trying
to resolve this! Please help!

(I will try this on suse 9.1 later today.)

This compiles:

#include <utility>
int main(){return 0;}

and this does not:

#include <boost/utility.hpp>
int main(){return 0;}

Both are compiled with:
/usr/bin/g++-3.3 main.cpp

There are over 1000 errors, most of them in this fashion:

In file included from /usr/include/gcc/darwin/3.3/c++/utility:66,
from /usr/include/boost/config/select_stdlib_config.hpp:20,
from /usr/include/boost/config.hpp:40,
from /usr/include/boost/utility/addressof.hpp:14,
from /usr/include/boost/utility.hpp:12,

Hi,

I'm affraid not, our sys admins installed a new gcc (3.4.3) and I
successufully managed to build it using this. (sparc-sun-solaris2.8)

Sorry not to be able to offer any more help,
Cheers
