I'm trying to compile commonc++2-1.1.0 on AIX 4.3.2 using g++ 2.95.3 (the latest we can get here unfortunately). I get this error message: /usr/include/strings.h:60: declaration of C function `void memcpy(void *, const void *, long unsigned int)' conflicts with /usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.2.0/2.95.3/include/string.h:92: previous declaration `void * memcpy(void *, const void *, long unsigned int)' here ... .../straits.h: In function `static char * string_char_traits<char>::copy(char *, const char *, long unsigned int)': .../straits.h:127: cannot convert `memcpy(s1, s2, n)' from type `void' to type `char *' However line 60 of strings.h is this: extern void bcopy(const void *, void *, size_t); Does anybody know what's wrong, or have an idea on how I can get around this and get it to compile? Why would bcopy override the declaration of memcpy? Thanks.
