Can't cross-compile to Android - 'rethrow_exception' is not a member of 'std'

[Nadav-Ruskin]

Description

I can't cross-compile the header to Android. Tried NDK 13b, 14b, and 16b. Is Android missing an integral part of the library? If so, please add a disclaimer.

[osboxes:/work/build] $ /usr/arm-linux-androideabi/bin/arm-linux-androideabi-g++ -std=gnu++14 -I ../3rdparty/catch/catch/ -o hello_world hello_world.cpp       
In file included from hello_world.cpp:1:0:
catch.hpp: In member function 'std::string Catch::ExceptionTranslatorRegistrar::ExceptionTranslator<T>::translate(std::vector<std::unique_ptr<const Catch::IExceptionTranslator> >::const_iterator, std::vector<std::unique_ptr<const Catch::IExceptionTranslator> >::const_iterator) const':
catch.hpp:1798:7: error: 'rethrow_exception' is not a member of 'std'
       std::rethrow_exception(std::current_exception());
       ^
catch.hpp:1798:30: error: 'current_exception' is not a member of 'std'
       std::rethrow_exception(std::current_exception());

Steps to reproduce

1. Install NDK. For comfort, I started out with an image from dockcross.
2. Put catch.hpp in a directory.
3. Make hello_world.cpp in same directory:

#include "catch.hpp"

TEST_CASE("test 1")
{
REQUIRE(1==1);
}

4. Compile, making sure to use the right flags.

[osboxes:/work/build] 1 $ /usr/arm-linux-androideabi/bin/arm-linux-androideabi-g++ -std=gnu++11 -o hello_world hello_world.cpp
In file included from hello_world.cpp:1:0:
catch.hpp: In member function 'std::string Catch::ExceptionTranslatorRegistrar::ExceptionTranslator<T>::translate(std::vector<std::unique_ptr<const Catch::IExceptionTranslator> >::const_iterator, std::vector<std::unique_ptr<const Catch::IExceptionTranslator> >::const_iterator) const':
catch.hpp:1798:7: error: 'rethrow_exception' is not a member of 'std'
       std::rethrow_exception(std::current_exception());
       ^
catch.hpp:1798:30: error: 'current_exception' is not a member of 'std'
       std::rethrow_exception(std::current_exception());
                              ^

Extra information

• Catch version: 2.2.0
• Operating System: Debian
• Compiler+version: arm-linux-androideabi-g++ versions 13b, 14b, and 16b.

std::rethrow_exception should be a part of conforming C++11 standard library and is required to compile Catch2.

[Nadav-Ruskin]

Should I report a bug here?

[horenmar]

Probably.

In the meantime, you might want to try Catch Classic in the Catch1.x branch, it still supports C++98.

[Nadav-Ruskin]

Thank you for the suggestion. I'll see if applicable.

[Nadav-Ruskin]

OK, this is a non-bug. android/ndk#648 solved it. Apparently NDK has to use --stl libc++ for proper C++11 support.

FYI I have reproduced the same error using a gcc5 docker image with a conan cross compiling toolchain for armv7 (This image, which is based on the conan docker image for gcc5 on armv7), using single-header catch2 v2.0.1
