Hi, With this piece of code I get an error that "ISO C++ forbids declaration of hash_map with no type":confused: #include <hash_map> ... hash_map<uint32_t,uint32_t> _regsMap; ... The file has the extension hxx. I searched and some say that hash_map is not stanrad in GCC. Any help?:wistle: thanks, -- View this message in context: http://old.nabble.com/iso-C%2B%2B-and-%E2%80%98hash_map%E2%80%99-problem-tp27241004p27241004.html Sent from the gcc - Help mailing list archive at Nabble.com.
