Compilation error with GCC4.6 in C++11 mode

[Antony Polukhin]

g++-4.6 -std=c++11 causes compilation error:

../../../boost/exception/info.hpp: In instantiation of ‘boost::error_info<boost::tag_original_exception_type, const std::type_info*>’:

../../../boost/exception/detail/exception_ptr.hpp:95:32:   instantiated from here

../../../boost/exception/info.hpp:66:5: error: ‘class boost::error_info<boost::tag_original_exception_type, const std::type_info*>’ has no member named ‘value_’

BOOST_NOEXCEPT_IF(boost::is_nothrow_move_constructible<value_type>::value) may help.

I was just testing 1.62.0 beta 2 and ran into this issue.

Used compiler: g++ (Ubuntu/Linaro? 4.6.3-1ubuntu5) 4.6.3

Boost build commands:

./bootstrap.sh --with-libraries=filesystem,exception,program_options,test,signals --prefix=/usr
./b2 link=shared runtime-link=shared optimization=speed variant=release cxxflags="-std=c++0x" install

With the same settings etc. I can successfully compile and run my code with Boost 1.59.0.

Let me know if you need more information to reproduce and fix this error.

[Emil Dotchevski]

Can I have an updated error log?

[kratz00@…]

The log is exactly the same or do you mean something else?

[Emil Dotchevski]

The problem is that the line numbers have changed and there are two similar lines, currently 60 and 67. The original report refers to value rather than value_, which probably means the error is at what is now line 60, though there may also be an error at line 67.

Maybe you can try the fix suggested in the original report?

[kratz00@…]

Here is the compile error I get with 1.62.0 beta 2

Regarding the suggested fix, I am not sure what to do with it.

[Emil Dotchevski]

Can you tell me what Exception headers are included in what order in yapl_linux.cpp?

[kratz00@…]

Sure, here is the full trace:

I did not expect it to work, but I just tested boost 1.62 anyway. No suprise, the error still exists and the trace looks the same:

[kratz00@…]

Any news on this issue?

[Emil Dotchevski]

I just looked at it again, I can't quite make sense of it. The definition of the error_info template does have a member named 'value_'. That template will be defined if you include info.hpp, but it is declared and left incomplete if you only include error_info.hpp. Is it possible that the error you're getting is because in this context info.hpp hasn't been included?

[kratz00@…]

Thanks Emil for looking into this.

This is test code (test.cpp), which reproduces the error:

#include <string>
#include <boost/exception/error_info.hpp>
#include <boost/exception/exception.hpp>
#include <boost/exception/info.hpp>

struct MyException: virtual boost::exception {};
typedef boost::error_info<struct error_info_string, std::string> errorInfoString;

int main(void) {
    throw MyException() << errorInfoString("doh");
    return 0;
}

[Emil Dotchevski]

Can you please try with latest develop branch? There was a bug where some types were defined as struct in one place and as class in another, and that's fixed now. With latest develop, I get no error with gcc 4.8.5.

[kratz00@…]

Hi Emil

I've tested the develop branch: the result stays the same :(

Do you by any chance have access to an Ubuntu 12.04 system? As such a system has the compiler in question.

• ​http://releases.ubuntu.com/12.04/
• ​https://sourceforge.net/projects/virtualboximage/files/Ubuntu%20Linux/12.04/

#include <iostream>
#include <boost/algorithm/hex.hpp>

int main(void)
{
    std::cout << boost::algorithm::hex(std::string("hi")) << "\n";
    return 0;
}

# g++ -v 2>&1 | grep version
gcc version 4.6.3 (GCC)

[gr]

boost/exception/exception.hpp contains specialization for error_info with member v_ instead value_

[kratz00@…]

I just gave boost 1.63 a spin, as expected, the error is still there. The error is exactly the same as before.

[Emil Dotchevski]

Can you confirm that the error_info_basic_test.cpp I added is equivalent to the one that issues the error for you? It succeeds for me under gcc-4.6.3, see ​https://travis-ci.org/boostorg/exception/jobs/188456592

[kratz00@…]

With error_info_basic_test.cpp I get the same error, as with my test code. I think what you are missing in your travis build is the compiler flag ("-std=c++0x") and that is the reason it succeeds.

[Emil Dotchevski]

Added workaround for g++4.6

[anonymous]

This isn't fixed. Boost 1.6.3, gcc 4.6.3 with flag -std=gnu++0x on Ubuntu 12.04.5. Same problem as above.

[Emil Dotchevski]

Please see ​https://travis-ci.org/boostorg/exception/jobs/203665051, notice CXXSTD=c++0x and the output of g++ --version:

g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3

Am I missing something?

[kratz00@…]

Hi Emil

I was just testing version 1.64.0 beta 1 and I could still reproduce this bug. Did the fix not make it in the beta?

[guenterbe@…]

Replying to Emil Dotchevski:

Please see ​https://travis-ci.org/boostorg/exception/jobs/203665051, notice CXXSTD=c++0x and the output of g++ --version:

g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3

Am I missing something?

Yes. Building the boost libs as you did is no problem.

The easiest way to reproduce the problem (gcc-4.6.4, c++0x mode, boost 1.64):

#include <boost/thread.hpp>

int main()
{
}

Compiling results in:

/opt/wandbox/boost-1.64.0/gcc-4.6.4/include/boost/exception/info.hpp:66:5: error: 'class boost::error_info<boost::tag_original_exception_type, const std::type_info*>' has no member named 'value_'

[guenterbe@…]

Compiling

#include <boost/thread.hpp>

will fail with gcc-4.6.4, c++0x and boost-1.64:

boost-1.64.0/gcc-4.6.4/include/boost/exception/info.hpp:66:5: error: 'class boost::error_info<boost::tag_original_exception_type, const std::type_info*>' has no member named 'value_'

(It used to work with boost 1.57, other versions not tested)

[Emil Dotchevski]

Can you try with the develop branch?

[Richard Hazlewood <boost@…>]

Had same issue, but can confirm it does compile on the develop branch - not surprising because the code (error_info_impl.hpp) is guarded with:

#if (__GNUC__*100+__GNUC_MINOR__!=406) //workaround for g++ bug

We found that boost::thread fails to compile with the 1.64.0 release.

[kratz00@…]

Looks like a fix for this ticket has made it into the Boost 1.65.0 beta 1 release, at least my code works with this version.

Thanks.

[kratz00@…]

Like the beta, the final 1.65.0 release fixes the reported problem for me. I think this ticket can be closed now.
