Compiling Boost 1.54.0 for the iOS simulator (6.1) on OS X 10.8.4
by Dan Leach 09 Aug '13

09 Aug '13

Hello, I am new to the Boost mailing list so please let me know if this is not the appropriate place to discuss my problem. I have successfully managed to compile several of the Boost libraries (regex, filesystem, thread) and create a framework for use with OS X, iOS, and the iOS simulator using this script: https://github.com/wuhao5/boost/blob/188e905626dbd522f65950102ed0c8ce77cb28… on Peter Goodliffe's work here: http://goodliffe.blogspot.com/2010/09/building-boost-framework-for-ios-ipho… Boost 1.53.0 using clang and linking against libc++. The script fails when compiling for the iOS simulator with Boost 1.54.0 with the following error:/bin/sh: line 1: -ftemplate-depth-128: command not found. I did quite a bit of digging and here is what I know: * In boost.sh, the iOS simulator bjam and compiler options include "-arch i386" * The release notes for Boost 1.54.0 state that "Boost no longer supports the 80386 target CPU" * The Boost 1.53.0 libraries mentioned above appear to compile fine for OS X, iOS, and the iOS simulator using the same script * The Boost 1.54.0 libraries appear to compile fine for OS X and iOS itself using the same script Here is what I think I know: * When passing "-d13" to bjam (to generate debug information), it appears that the variable "CONFIG_COMMAND" is not being set when building for the iOS simulator. For the other configurations, this variable is set to the path to clang and includes the compiler options. For the simulator, it is empty which I believe leads to the error above as when bjam attempts to run the compiler using this variable, it instead runs some appended options which begin with the template depth. Therefore, the CONFIG_COMMAND variable does not appear to be being set properly causing the failure. I do not know why it's not being set as I don't know enough about the Boost build system to sift through the rest of the output generated with the "-d13" flag. I suspect an incompatibility with the "-arch i386" option was introduced with 1.54.0. I've tried changing this to "-arch i486" and "-arch x86_32" but the same problem occurs. Has anyone else had success with this? I'd like to use Boost.Log which is why I'm even attempting this with 1.54. Thanks!

[program_options] Parsing config files
by Michael Powell 08 Aug '13

08 Aug '13

Hello, Need a little help grasping the nature of parse_config_file. The example: http://www.boost.org/doc/libs/1_54_0/doc/html/program_options/tutorial.html… also seems a bit lacking: says that there are two calls to store, but I only see one. Maybe the example has not been updated? What I need to know is, if we specify some options, do we specify the same option names in a config file? So that if we have an option on the command like like: --my-option-name 1234, then the corresponding line in the config file would go: my-option-name=1234 ? Thank you. Regards, Michael Powell

Hello, I am trying to run some regression tests, and then create a status report following the documentation provided here: http://www.boost.org/doc/libs/1_54_0/tools/regression/doc/library_status.ht… I am using version Boost Version 1.53.0 on Suse 11 patch 1.

Start from your command line environment. 2. set the current directory to:../libs/<library name>/test 3. Invoke one of the following: o ../../../tools/regression/src/library_test (*nix). o ..\..\..\tools\regression\src\library_test (windows). 4. This will display short help message describing the how to set the command line arguments for the compilers and variants you want to appear in the final table. 5. Setting these arguments requires rudimentary knowledge of bjam usage. Hopefully, if you've arrived at this page you've gained the required knowledge during the installation and library build process. 6. Rerun the above command with the argument set accordingly. 7. When the command terminates, there should be a file named "library_status.html" in the current directory. 8. Display this file with any web browser. The problem is when it calls library_status there is an error about a invalid bin directory.

cannot use boost asio 1.43 with visual studio 2008
by bnsteel 07 Aug '13

07 Aug '13

Hello, I tried using boost 1.43 with my project and am having a problem compiling using the asio libraries. There is a namespace 'generic' and my VS (2008 and 2010) doesn't allow that word. I am guessing it is a keyword in visual studio? Is there a way I can disable the use of the 'generic' keyword? In my editor, the word generic is colored just like the 'namespace', '#define' and '#include' , 'if', 'else', 'for',... etc. brooke -- View this message in context: http://boost.2283326.n4.nabble.com/cannot-use-boost-asio-1-43-with-visual-s… Sent from the Boost - Users mailing list archive at Nabble.com.

[proposal] are_same on type_traits
by skypjack 06 Aug '13

06 Aug '13

Hi all, I've developed, tested and documented a variadic extension of is_same (named are_same). It can be useful to verify more than two arguments using a single expression. I sent the proposal to the devel list. However I would like to know if it can be of interest for you. Thanks in advance for your reply. Best Regards, Michele --

Re: [Boost-users] Derived class is not serialising/de-serialising...
by Marcus MacWilliam 06 Aug '13

06 Aug '13

Hello, My previous post contained a minimal example, which was incomplete, deliberately so as not to bloat the post with code. However Jeff Flynn has requested a minimal code example. I have attached several files for classes to this e-mail. * BaseClass - the base class, which has a serialize method * DerivedClass - a sub-class with its own serialize method * InstantiableClass - the class actually instantiated from DerivedClass * Main - code example of the client/server that serializes and de-serializes the InstantiableClass object. Our system automatically inserts some pre-compiled headers so to get the code to compile you may need to add your own #includes. The output from the main program is this: Serializing... BOOST: I am an Instantiable class object BOOST: I am in BaseClass::serialize De-serializing... BOOST: I am an Instantiable class object BOOST: I am in BaseClass::serialize Assertion failed: dynamic_cast<InstantiableClass&>(object).getCom() == 20, file Main.cc, line 8 This highlights the polymorphism problem in a nutshell. The overloaded what() method is telling me that in both the client and server code the objects is an InstantiableClass object. However the Derived::serialize is not being called on either side. Thus the data (m_com) from the DerivedClass is not being serialized and is lost. The compiler, and debugger, is telling me my object is an InstantiableClass, however when boost calls serialize on the object, the code in the BaseClass and not the Derived class is being called. Any help greatly appreciated. -- Marcus A.T MacWilliam, Senior Software Engineer. 1Spatial Ltd. Tel: +44 (0)1223 420414, ext 2289, Mob: +44 (0)7803 706597.
