c++ - why doesn't clang++ compile the following code? -


i have following code:

#include <type_traits>  int main() { }

g++ file.cc -std=c++0x

works fine.

however, need use clang++ reason.

when try

clang++ file.cc -std=c++0x

i bunch of errors:

in file included file.cc:1: in file included /usr/include/c++/4.4.4/type_traits:50: /usr/include/c++/4.4.4/tr1_impl/type_traits:230:41: error: expected ')'     struct is_function<_res(_argtypes......)>                                         ^ /usr/include/c++/4.4.4/tr1_impl/type_traits:230:28: note: match '('     struct is_function<_res(_argtypes......)>                            ^ /usr/include/c++/4.4.4/tr1_impl/type_traits:230:12: error: redefinition of 'is_function<type-parameter-0-0 (type-parameter-0-1, ...)>'     struct is_function<_res(_argtypes......)>            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/c++/4.4.4/tr1_impl/type_traits:227:12: note: previous definition here     struct is_function<_res(_argtypes...)>            ^ /usr/include/c++/4.4.4/tr1_impl/type_traits:233:29: error: type qualifier not allowed on function     struct is_function<_res(_argtypes...) const> ....

clang++ --version gives:

clang version 2.8 (branches/release_28) target: x86_64-redhat-linux-gnu thread model: posix

any ideas how fix that? (-std=c++11 doesn't work, not recognized.)

clang 2.8 not support c++11 features, need upgrade compiler use them.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
