Do you perhaps have extern "C" block still open before you include ? I get identical errors compiling the following test program:

extern "C" { #include }

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 #endif #include <iostream> #include #include ... ... 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. Cheers Chris This message has been scanned but we cannot guarantee that it and any attachments are free from viruses or other damaging content: you are advised to perform your own checks.

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

#include <utility> int main() {}

If so, it's not a boost problem.

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$ Cheers Chris This message has been scanned but we cannot guarantee that it and any attachments are free from viruses or other damaging content: you are advised to perform your own checks.

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.

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 Chris doktora wrote:

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 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:
