Both fstream and iostream are useful too. You said that there is no filesystem in the browser, however I need to open files in C++ to load data like scripts, textures, configs, etc. Duetto have to workout this somehow like via http requests or preloading files into the scripts.
About iostream, it is useful for printing information for debugging purposes with std::cout, for instance I tried using printf from cstdio just to see what would happen and it did nothing, I got no output in my javascript debugger from firefox or chrome, I think that should me implemented too. -- You received this bug notification because you are a member of Leaningtech Team, which is subscribed to Duetto. https://bugs.launchpad.net/bugs/1247336 Title: Unable to include iostream, fstream or sstream Status in Duetto: C++ for the Web: Confirmed Bug description: When I try to incluse iostream, fstream or sstream I got the following errors: s $ /opt/duetto/bin/clang -Os -std=c++11 -S -target duetto HelloClient.cpp -o HelloClient.js In file included from HelloClient.cpp:5: In file included from /opt/duetto/include/c++/v1/iostream:38: In file included from /opt/duetto/include/c++/v1/ios:216: In file included from /opt/duetto/include/c++/v1/__locale:18: In file included from /opt/duetto/include/c++/v1/mutex:176: In file included from /opt/duetto/include/c++/v1/__mutex_base:15: In file included from /opt/duetto/include/c++/v1/chrono:268: /opt/duetto/include/c++/v1/ratio:256:20: error: integer constant is larger than the largest unsigned integer type typedef ratio<1LL, 1000000000000000000LL> atto; ^ /opt/duetto/include/c++/v1/ratio:257:23: error: integer constant is larger than the largest unsigned integer type typedef ratio<1LL, 1000000000000000LL> femto; ^ /opt/duetto/include/c++/v1/ratio:258:26: error: integer constant is larger than the largest unsigned integer type typedef ratio<1LL, 1000000000000LL> pico; ^ /opt/duetto/include/c++/v1/ratio:269:21: error: integer constant is larger than the largest unsigned integer type typedef ratio< 1000000000000LL, 1LL> tera; ^ /opt/duetto/include/c++/v1/ratio:270:18: error: integer constant is larger than the largest unsigned integer type typedef ratio< 1000000000000000LL, 1LL> peta; ^ /opt/duetto/include/c++/v1/ratio:271:15: error: integer constant is larger than the largest unsigned integer type typedef ratio<1000000000000000000LL, 1LL> exa; ^ In file included from HelloClient.cpp:5: In file included from /opt/duetto/include/c++/v1/iostream:38: In file included from /opt/duetto/include/c++/v1/ios:216: In file included from /opt/duetto/include/c++/v1/__locale:18: In file included from /opt/duetto/include/c++/v1/mutex:176: /opt/duetto/include/c++/v1/__mutex_base:37:5: error: unknown type name 'pthread_mutex_t' pthread_mutex_t __m_; ^ /opt/duetto/include/c++/v1/__mutex_base:57:13: error: unknown type name 'pthread_mutex_t' typedef pthread_mutex_t* native_handle_type; ^ /opt/duetto/include/c++/v1/__mutex_base:42:41: error: use of undeclared identifier 'PTHREAD_MUTEX_INITIALIZER' constexpr mutex() _NOEXCEPT : __m_(PTHREAD_MUTEX_INITIALIZER) {} ^ /opt/duetto/include/c++/v1/__mutex_base:304:5: error: unknown type name 'pthread_cond_t' pthread_cond_t __cv_; ^ /opt/duetto/include/c++/v1/__mutex_base:348:13: error: unknown type name 'pthread_cond_t' typedef pthread_cond_t* native_handle_type; ^ /opt/duetto/include/c++/v1/__mutex_base:308:44: error: use of undeclared identifier 'PTHREAD_COND_INITIALIZER' constexpr condition_variable() : __cv_(PTHREAD_COND_INITIALIZER) {} ^ In file included from HelloClient.cpp:5: In file included from /opt/duetto/include/c++/v1/iostream:38: In file included from /opt/duetto/include/c++/v1/ios:216: In file included from /opt/duetto/include/c++/v1/__locale:18: /opt/duetto/include/c++/v1/mutex:192:5: error: unknown type name 'pthread_mutex_t' pthread_mutex_t __m_; ^ /opt/duetto/include/c++/v1/mutex:207:13: error: unknown type name 'pthread_mutex_t' typedef pthread_mutex_t* native_handle_type; ^ /opt/duetto/include/c++/v1/mutex:259:5: error: unknown type name 'pthread_t' pthread_t __id_; ^ /opt/duetto/include/c++/v1/mutex:285:5: error: unknown type name 'pthread_t' pthread_t __id = pthread_self(); ^ /opt/duetto/include/c++/v1/mutex:285:22: error: use of undeclared identifier 'pthread_self' pthread_t __id = pthread_self(); ^ /opt/duetto/include/c++/v1/mutex:359:9: error: use of undeclared identifier 'sched_yield' sched_yield(); ^ /opt/duetto/include/c++/v1/mutex:368:9: error: use of undeclared identifier 'sched_yield' sched_yield(); ^ fatal error: too many errors emitted, stopping now [-ferror-limit=] To manage notifications about this bug go to: https://bugs.launchpad.net/duetto/+bug/1247336/+subscriptions -- Mailing list: https://launchpad.net/~leaningtech-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~leaningtech-dev More help : https://help.launchpad.net/ListHelp
