コンパイルC++コードにこのコードを考えるとブーストのregex_match

Question

では？

26行目の「const」を削除して、同じコマンドでコンパイルした場合。私はこのエラーが発生します ：

更新：

は、このコンパイルで解決およびリンク：

g++ -I ~/.boost/include/boost-1_37 test.cc -o test /home/foolishbrat/.boost/lib/libboost_regex-gcc33-mt-1_37.a 

Answer 1

にconstキーワードを削除してください。 -l <path to libraries>をビルドコマンドに追加

Answer 2

if (const regex_match(InputString, e)) {// this is line 26 

あなたがする必要がある（実際、すべきではありませんここではconstと言う。単語を削除するだけで、少なくともこのエラーは消えるはずです。

Answer 3

あなたが必要なブーストライブラリをリンクする必要がライン26
