Hi Daniel, I tried some other versions based on the release date of the project and boosts. I tried 1.38 and 40 and 42 and 44 and 46. All of them return some undefined references. How can i find which boost version is used in the project?

Many undefined references for libboost_filesystem
by Mahmood N 13 Oct '17

Hi, I am trying to build a suite as described at https://github.com/gpgpu-sim/ispass2009-benchmarks Some of the benchmarks use boost. For example, AES/Makefile has LINKFLAGS := -L$(BOOST_LIB) -lboost_filesystem Also, the Makefile.ispass-2009 in the root folder has the following settings SETENV=export BINDIR=$(BINDIR); \ export ROOTDIR=$(NVIDIA_COMPUTE_SDK_LOCATION)/C/src/; \ export BINSUBDIR=$(BINSUBDIR); \ export BOOST_LIB=/home/mahmood/boost_1_46_0/lib; \ export BOOST_ROOT=/home/mahmood/boost_1_46_0/include; \ export BOOST_VER=""; \ export OPENMPI_BINDIR=/usr/bin/; I manually built boost_1_46_0 with the steps described at http://www.boost.org/doc/libs/1_46_1/doc/html/bbv2/installation.html The installations was successful and I can see lib/ and include/ folders mahmood@vb:boost_1_46_0$ find lib -name libboost_system* lib/libboost_system.so.1.46.0 lib/libboost_system.so lib/libboost_system.a mahmood@vb:boost_1_46_0$ find lib -name libboost_filesystem* lib/libboost_filesystem.so lib/libboost_filesystem.a lib/libboost_filesystem.so.1.46.0 However, as I run “make -f Makefile.ispass-2009”, I get many undefined errors about libboost_filesystem.

[coroutine] MinGW: terminate called after throwing an instance of 'boost::context::detail::forced_unwind'
by Jan Niklas Hasse 13 Oct '17

13 Oct '17

Hi :) I've tried to compile this simple Boost.Coroutine example: #include <iostream> #include <boost/coroutine2/all.hpp> void foo(boost::coroutines2::asymmetric_coroutine<void>::push_type& yield) { for (int i = 0; i < 10; ++i) { std::cout << i << std::endl; yield(); } } int main() { boost::coroutines2::asymmetric_coroutine<void>::pull_type coroutine(foo); for (int i = 0; i < 5; ++i) { coroutine(); } } On Linux this works as expected, just as on Windows with Visual Studio. But when I cross-compile on Linux using i686-w64-mingw32-g++ src/main.cpp -lboost_context-mt The resulting exe crashes with: 0 1 2 3 4 5 6 terminate called after throwing an instance of 'boost::context::detail::forced_unwind' abnormal program termination There's a similar problem on StackOverflow: https://stackoverflow.com/questions/45569418/how-to-use-boost-context-corre… But I'm having the crash only with the cross-compiled version, not MSVC. Am I doing something wrong? Or might this be a bug in Fedora's mingw32-boost package?

1.65.1 as modular packages on Conan.io
by Rene Rivera 13 Oct '17

13 Oct '17

Following on with the announcement before CppCon of the 1.64.0 modular packages here we are with more. I'm pleased to announce that the 1.65.1 Boost C++ Libraries are now available individually using the Conan package manager. There's even some improvements for the 1.64.0 package also :-) Find out more from the Bincrafters post here <http://bit.ly/2g6VEpp>[1]. For help using the packages you can bug the Bincrafters team in the #Conan CppLan Slack channel <http://bit.ly/2ykeqC0>[2]. Conan is a C/C++ (and more) package manager that supports an open ended set of build system and tool integrations including: VisualStudio, Xcode, CLion, Ninja, QMake, Premake, and yes even CMake <http://bit.ly/2xzhpbg>[3].

boost::filesystem and writing to Windows programdata structure
by Tim Burgess 12 Oct '17

12 Oct '17

Hi, I've an application that has been working fine under Windows 7, but I'm now fixing up for running on later Windows versions. I've been hitting unhandled exceptions when writing to c:\programdata\(my company)\(my app name)\ and understand that this is due to the permissions for such folders being more restrictive on Windows 8, 8.1 and 10. My research seems to indicate that I can modify my installer to set up my folders with appropriate permissions at install-time, but I'd prefer to use boost::filesystem to check folder/file permissions then change them at run-time, if necessary using appropriate csidl values. Can anybody offer any advice, please? Best wishes. Tim Burgess

[stacktrace] Trace information from GetExceptionInformation()?
by Nat Goodspeed 11 Oct '17

11 Oct '17

In an __except() filter expression (Microsoft Structured Exception), it's legal to call GetExceptionInformation() to retrieve a pointer to an _EXCEPTION_POINTERS struct. A little bit of Google searching turned up a few recipes for walking the stack information indirectly provided by that _EXCEPTION_POINTERS data. Would it be reasonable to have a Microsoft-specific stacktrace constructor accepting _EXCEPTION_POINTERS*? Or perhaps a factory function? I would like to be able to capture the platform-specific _EXCEPTION_POINTERS information, but then, once I have it in hand, engage the rest of the Boost.Stacktrace functionality. Apologies if this has already been asked and answered. If so, please simply point me to the previous discussion. Thank you!

boost::interprocess::managed_mapped_file filename
by Markus Bonk 10 Oct '17

10 Oct '17

Hi, Unfortunately wmanaged_mapped_file constructors use char instead of wchar for the filename. This causes big problems on windows where %appdata% and %localappdata% include the user name which may include Unicode characters that after conversion result in the windows ‘A’ methods failing to find the referenced file. I don’t know of any work around except using Unicode filenames. Does anyone know of a way around this. Are there any plans of making wmanaged_mapped_file use wchar for the filenames?

Compiling boost with optional _GLIBCXX_DEBUG support
by Jayesh Badwaik 09 Oct '17

09 Oct '17

Hi, How to compile boost so that compilation of user programs both with _GLIBCXX_DEBUG and without _GLIBCXX_DEBUG is supported? Currently, if I compile boost with _GLIBCXX_DEBUG then I cannot compile my programs without this flag, and vice versa. The actual error comes from program_options attached in a file. I gather from the interweb that the error is well known, however, I could not find instructions to compile boost such that both options are supported. -- Cheers Jayesh Badwaik https://www.jayeshbadwaik.in

[asio] "reverse" stream?
by Phil Sean 07 Oct '17

07 Oct '17

Hi, Is there a stream (or other implementation) in asio that reverses the next layer and the read()/write() layer of another stream? For example, a reverse ssl::stream would send/receive data in clear text, but read()/write() operations should rather expect encrypted data. Thanks.
