Boost::cregexp_iterator复杂性错误
boost::cregexp_iterator compliation errors
我正在尝试使用boost::cregexp_iterator，如http://www.boost.org/doc/libs/1_55_0/libs/regex/doc/html/boost_regex/ref/regex_iterator.html
所示// Loop through all the patterns
auto sessionReconstructionsEnd = _sessionReconstructions.end();
for (auto sr = _sessionReconstructions.begin(); sr != sessionReconstructionsEnd; ++sr) {
const std::string& pattern = sr->first;
const auto& editors = sr->second;
regex re(pattern);
...
for (auto session = sessions.begin(); session != sessionsEnd; ++session) {
for (size_t chunkNumber = 0; chunkNumber < sessionChunks.size(); ++chunkNumber) {
const auto& chunkData = sessionChunks[chunkNumber].data;
cregex_iterator reIteratorEnd;
cregex_iterator reIterator(
reinterpret_cast<const char*>(chunkData.data()),
reinterpret_cast<const char*>(chunkData.data()) + chunkData.size(),
re); // Here the search is being done...
所有其他代码被注释掉。我得到以下错误:

怎么了?
UPDATE:问题是与标志——std=c++11 -我发布另一个帖子这个问题。UPDATE2:问题是我使用的是旧版本的boost(1.4.3)，移动到最新解决它
让我为你做你的工作告诉你我如何分析这个问题:
#include <boost/regex.hpp>
#include <boost/cregex.hpp>
#include <vector>
int main()
{
using namespace boost;
regex re(".*");
const std::vector<char> chunkData;
cregex_iterator reIteratorEnd;
cregex_iterator reIterator(
reinterpret_cast<const char*>(chunkData.data()),
reinterpret_cast<const char*>(chunkData.data()) + chunkData.size(),
re); // Here the search is being done...}
}
对我来说编译得很好。你的问题中没有任何else是我们可以复制的
你可以从那里接手。看看它什么时候开始失败。90%的时候，失败的原因就很明显了。否则，带着更清晰、更好的问题回来。
PS。- 我知道这在技术上不是一个答案。尽管如此，我认为它还是有帮助的(而且它不太适合在评论中)
- 你当然不需要在我的SSCCE中重新解释演员。我假设你的
chunkData可能(谁知道)实际上是std::deque<unsigned char>或类似的?在这种情况下，看看是否应该使用static_cast:什么时候应该使用static_cast、dynamic_cast、const_cast和reinterpret_cast ?和常规类型转换与静态类型转换与动态类型转换
