[Boost.Test] Using boost::exception
by Ovanes Markarian 06 Mar '12

06 Mar '12

Hi! I think it might be a great feature if Boost.Test would be able to print diagnostic information saved in boost::exception. Actually my code havily relies on boost::exception. If one of my tests fail, I usually get nothing saying "std::exception occured" error message. But if Boost.Test could just catch boost::exception and print the default diagnostig info it would be a great help. Best Regards, Ovanes

Complex serach and replace in C++ string
by Claude 06 Mar '12

Hi! Is it possible search and replace or delete a character in a piece of string delimited by 2 positions found by the method find() (find() return position (size_t) and not an iterator) using some function of boost? -- View this message in context: http://boost.2283326.n4.nabble.com/Complex-serach-and-replace-in-C-string-t… Sent from the Boost - Users mailing list archive at Nabble.com.

Filesystem Library Bug
by Sam Hertz 06 Mar '12

06 Mar '12

Hi, I am having some trouble with the latest version of the Boost Filesystem library. The following causes a segmentation fault: boost::filesystem::create_directory(boost::filesystem::current_path()/"test"); boost::filesystem::remove_all(boost::filesystem::current_path()/"test"); It is difficult for me to debug since the call to remove_all dives into a library file. My system configuration is: Operating System: Ubuntu 11.10 Compiler: clang++ (I can reproduce the error with g++) Boost Version: 1.49.0 (compiled with clang++) Thanks, Sam

Classification: UNCLASSIFIED Caveats: NONE New and struggling with BGL, which IMO the best for graphs. I will keep at it. This should be a simple fix for r/w Graphviz example by Douglas Gregor... The errors in the typescript (attached) are the result of "write_graphviz(std::cout,g,dp,std::string("id"));" Could someone tell me how/what to correct. Thank you.

Aborting on Boost.Test check failure
by Jeremiah Willcock 06 Mar '12

06 Mar '12

Is there a way to force an abort() or some other kind of debugger-catchable event when a Boost.Test test case (such as a BOOST_CHECK) fails? Is there a function I can set a breakpoint on? I do not see anything like that in the documentation. I am running on Linux with gdb. -- Jeremiah Willcock

I just read about the Boost.Generic library at https://github.com/boostcon/2011_presentations/raw/master/thu/Boost.Generic…. It looks amazing! I understand it's not fully complete, but are the sources available somewhere? Thanks, Nate.

05 Mar '12

Hi All I have installed openmpi in C:\Program Files\OpenMPI_v1.5.4-win32\ in an XP box and want to compile boost to produce graph-parallel library. But got the following error: The system cannot find the path specified. The system cannot find the path specified. The system cannot find the path specified. The system cannot find the path specified. MPI auto-detection failed: unknown wrapper compiler C:/Program Files/OpenMPI_v1. 5.4-win32/bin/mpic++.exe Please report this error to the Boost mailing list: http://www.boost.org You will need to manually configure MPI support. MPI launcher: mpirun -np when I ran in a Visual Studio 2010 command prompt: b2 --toolset=msvc-10.0 --build-type=complete architecture=x86 address-model=32 stage --debug-configuration I added the MPI config in boost_1_48_0\tools\build\v2\user-config.jam as below: using mpi : "C:/Program Files/OpenMPI_v1.5.4-win32/bin/mpic++.exe" ; Could anyone help on this?

Boost msm
by keithzz 05 Mar '12

05 Mar '12

newbi question pleasee bare with me as Im struggling with this. I want to use boost msm state machine but i am having a hard time imagining how it works. Let say we only have 2 states (s1, s2) and to go from s1 to s2 you need event e1 to be fired and to bo back you need another one e2. e1 and e2 can only be fired from within s1 and s2 respectively. Now in main() I start by starting the statemachine (start()) then ill have a while loop that every 1 min will go back to the state machine but have to pick up from where it left.i.e. main() { MSM.start(); //start state machine while (a_condition) { ProcessInputsfromIO(); Go_backtoStatemachine(); //how can i do this? delay(1min) } MSM.stop(); } So basically when a state finishes executing, the statemachine will exit, then ill have a delay of 1 minutes, then the while loop will need to take me back to the state I was before I exit, or I think that's how we should implement a state machine. Is what I am asking for out of the ordinary? If yes then how do people implement a non-blocking state machine? if no, then how can I implement Go_backtoStatemachine()? -- View this message in context: http://boost.2283326.n4.nabble.com/Boost-msm-tp4444830p4444830.html Sent from the Boost - Users mailing list archive at Nabble.com.
