Hi, This occur when trying to compile the getaddrinfo() module under MinGW:
checking for library containing getaddrinfo... no checking for getaddrinfo... no checking for getaddrinfo in ws2tcpip.h and -lws2_32... yes checking for gai_strerror... no [...] checking whether gai_strerror is declared... yes gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I. -I.. -g -O2 -Wall -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wbad-function-cast -Wcast-qual -Wcast-align -Wnested-externs -Wunused -MT gai_strerror.lo -MD -MP -MF .deps/gai_strerror.Tpo -c gai_strerror.c -DDLL_EXPORT -DPIC -o .libs/gai_strerror.o gai_strerror.c:68: conflicting types for `gai_strerrorA' c:/MinGW/include/ws2tcpip.h:301: previous declaration of `gai_strerrorA' The definition in ws2tcpip.h look like: char* WSAAPI gai_strerrorA(int); WCHAR* WSAAPI gai_strerrorW(int); #ifdef UNICODE #define gai_strerror gai_strerrorW #else #define gai_strerror gai_strerrorA #endif /* UNICODE */ As a result, shouldn't we always declare gai_strerror() in case the function is missing but the declaration is available?
