is_dereferenceable.hpp fails to compile with Apple Clang 3.0

Hi All, I am trying to use boost::iostreams. When I include boost/iostreams/filtering_streambuf.hpp (even if I don't declare any filtering_streambuf variables) I get the following compilation error: is_dereferencable.hpp: Parse Issue: Expected unqualified-id The problem is in this code: template <class T> struct impl { static typename boost::remove_cv<T>::type& x; BOOST_STATIC_CONSTANT( bool , value = sizeof(is_dereferenceable_::check BOOST_PREVENT_MACRO_SUBSTITUTION(BOOST_comma(*x,0))) == 1 ); }; Compiler: Apple Clang 3.0, with -std=c++0x flag Any help would be greatly appreciated. Thanks Istvan

Query on Boost.iostreams
by Leo Carreon 12 Dec '11

12 Dec '11

Hi, I’m building Boost 1.47.0 for Windows with VS 2010 using the following commands: .\bootstrap.bat .\b2 -sZLIB_SOURCE=c:\zlib-1.2.5 -sBZIP2_SOURCE=c:\bzip2-1.0.6 link=static,shared runtime-link=shared address-model=32 variant=release install 2>&1 | tee libwin32.log The resulting Boost\lib directory contains the following files: boost_bzip2-vc100-mt-1_47.dll boost_bzip2-vc100-mt-1_47.lib libboost_bzip2-vc100-mt-1_47.lib boost_zlib-vc100-mt-1_47.dll boost_zlib-vc100-mt-1_47.lib libboost_zlib-vc100-mt-1_47.lib I created test applications to use the shared ZLIB and BZIP2 libraries which means I had to link with the corresponding import libraries. I discovered that the test application for the ZLIB library is able to execute correctly. However, the test application for the BZIP2 library fails because it is looking for LIBBZ2.DLL instead of boost_bzip2-vc100-mt-1_47.dll. I used dumpbin.exe to check the contents of the BZIP2 import library and it is definitely referring to LIBBZ2.DLL. I tried to locate the issue in the JAM files but since I’m a newbie with JAM files I couldn’t locate what is causing this issue. At the moment, my workaround is simply creating a copy of boost_bzip2-vc100-mt-1_47.dll as LIBBZ2.DLL although ideally this shouldn’t be necessary. Can this problem be fixed in the next release of the Boost libraries. Do I need to raise a bug for this? Kind regards, Leo

[boost::thread] can not link on open suse
by Kaz 11 Dec '11

Hi All, I have downloaded 1.4.8 on a new machine running suse 12.1 Kde, and built it using bjam install option. Now I have a very simple threading program as follows #include <boost/thread.hpp> #include <iostream> void func() { for(int i = 0; i < 10; ++i ) std::cout<<i<<std::endl; } int main () { boost::thread th0(func); th0.join(); return 0; } when I try to compile it using this command g++ -static -I./Built_Boost_1.4.8.0/include -L./Built_Boost_1.4.8.0/lib/ boostThreadTest.cpp -lboost_thread -lpthread -o threadTest I get following error /usr/lib/gcc/i586-suse-linux/4.6/../../../../i586-suse-linux/bin/ld: cannot find -lpthread /usr/lib/gcc/i586-suse-linux/4.6/../../../../i586-suse-linux/bin/ld: cannot find -lm /usr/lib/gcc/i586-suse-linux/4.6/../../../../i586-suse-linux/bin/ld: cannot find -lc collect2: ld returned 1 exit status I have searched for libpthread.a, but can not find it in my system. although I can see these /lib/libpthread.so /usr/include/pthread.h also if I remove -lpthread from build command, I still get the last two errors i-e /usr/lib/gcc/i586-suse-linux/4.6/../../../../i586-suse-linux/bin/ld: cannot find -lm /usr/lib/gcc/i586-suse-linux/4.6/../../../../i586-suse-linux/bin/ld: cannot find -lc collect2: ld returned 1 exit status So question is, do I need libpthread ? ( from my past experience I think I do, but not sure). if yes, then how can I get it, and if not, then how can I get this program to compile. Any help will be appreciated. Kaz

OSX Framework
by Kraus Philipp 11 Dec '11

11 Dec '11

Hello, I'm using Boost for a long time and create my package with bjam. Is there an option to create an OSX framework? OSX can handle libraries and headers in a special directory structure under eg /Library/Framework, can I build this structure with bjam or should I create it myself? Thanks Phil

[Units] Require help troubleshooting a template error with linear_algebra.hpp
by Stephen Torri 11 Dec '11

11 Dec '11

Below is a dump of the build output from compiling the stand alone example. In order to understand what I am doing I am trying to setup a boost unit system where length is in kilometers, angle is in degrees and time is in minutes. I would like to have the ability to enter automatically convert angles from degrees to radians. In addition I am attemping to make the angle types I use to be dimensionless.

Hi Im use boost library and during the compilation on debbug mode I satarted the following warnings: 1386 IntelliSense: #error directive: "Macro BOOST_LIB_NAME not set (internal error)" c:\boost_1_47_0\boost_1_47_0\boost\config\auto_link.hpp 102 1387 IntelliSense: #error directive: "Incompatible build options" c:\boost_1_47_0\boost_1_47_0\boost\config\auto_link.hpp 111 Is this a known issue? Can I ignore it? and if not, what did I do wrong? Thanks Ohad Barta

[thread] - install - libraries not referencing?

I apologize if this question is asked frequently by noobs. Essentially, the boost functions are not recognized. I installed the prebuilt boost package on ubuntu (ostensibly 1.43), and wonder if it's working correctly. I am working through the threading chapter from *Introduction to the C++ Boost Libraries – Volume I – Foundations,* and replicated their first example: #include <boost/thread.hpp> #include<iostream> using namespace std; using namespace boost; using namespace boost::this_thread; void fxn1() { for (int i=0; i<10; ++i) { cout << i << ") Do something in parallel with main method." << endl; boost::this_thread::yield(); }} int main() { boost::thread t(&fxn1); for (int i=0;i<10; i++) { cout << i << ". Do something in main method." << endl; } return 0; } using g++ boosttest1.c -o boosttest1 the compiler throws errors to each reference of a boost function (I have removed the names of temp files referenced by the compiler): undefined reference to `boost::this_thread::yield()' undefined reference to `boost::thread::~thread()' In function `boost::detail::thread_data_base::thread_data_base()': undefined reference to `vtable for boost::detail::thread_data_base' In function `boost::thread::thread<void (*)()>(void (*)(), boost::disable_if<boost::is_convertible<void (*&)(), boost::detail::thread_move_t<void (*)()> >, boost::thread::dummy*>::type)': undefined reference to `boost::thread::start_thread()' etc. Please respond if the remainder of the messages are cogent. If I comment out both lines with boost, the compile works perfectly, and if I comment out only the second, I receive: In function `fxn1()': boostthreadtest.c:(.text+0x43): undefined reference to `boost::this_thread::yield()' collect2: ld returned 1 exit status How do I reference the libraries correctly? It seems as though the more detailed thread.hpp files are correctly referenced and present, but are not being noticed by the compiler. Thanks for your patience. floobit

[boost] compilation warnings questions by a newbee

Hi, I am writing my first boost program and having trouble with the compiler warning against boost 1.44.0. Is there any way to get rid of those warnings so I can focus on real warnings in my code ? The gist of warning is : boost_1_44_0/include/boost/mpl/aux_/integral_wrapper.hpp:73:96: warning: the result of the conversion is unspecified because '-0x00000000000000001' is outside the range of type 'boost::numeric::udt_builtin_mixture_enum' [-Wconversion] Any help or pointers are appreciated. Neeraj ====== The following program is a cut down version of my code, just declares sregex #include <iostream> #include <boost/xpressive/xpressive.hpp> int main (int _argc, const char** _argv) { std::cout << "argc=" << _argc << " argv=" << _argv << std::endl; using namespace boost::xpressive; std::string keyword(""); sregex const re(sregex::compile(keyword, sregex::icase)); } ====== The

[interprocess] atomic_write32
by peter jacobsen 09 Dec '11

09 Dec '11

I have noticed that for Windows, atomic_write32 is defined thus: inline void atomic_write32(volatile boost::uint32_t *mem, boost::uint32_t val) { winapi::interlocked_exchange(reinterpret_cast<volatile long*>(mem), val); } Whereas otherwise like this: inline void atomic_write32(volatile boost::uint32_t *mem, boost::uint32_t val) { *mem = val; } the reads are both: return *mem; Windows documentation states that: 'Simple reads and writes to properly-aligned 32-bit variables are atomic operations.' [http://msdn.microsoft.com/en-us/library/windows/desktop/ms684122%28v=vs.85%…] Is there a reason for this? Thanks, Peter

Unexpectedly this does not seem to work. Consider: boost::filesystem::path a("foo/bar/"), b("root/test"); a.append( b.begin() + 1, boost::filesystem::const_iterator() ); \\ Expects a == "foo/bar/test" Am I missing something? Kind regards, Sebastian Karlsson
