Currently only MinGW is supported. See the gnulib manual regarding
|
||
|
|
Windows sockets. MinGW has the header files winsock2.h and
|
||
|
|
ws2tcpip.h that declare the sys/socket.h definitions we need. Note
|
||
|
|
that you can influence which definitions you get by setting the
|
||
|
|
WINVER symbol before including these two files. For example,
|
||
|
|
getaddrinfo is only available if _WIN32_WINNT >= 0x0501 (that
|
||
|
|
symbol is set indirectly through WINVER). You can set this by
|
||
|
|
adding AC_DEFINE(WINVER, 0x0501) to configure.ac. Note that your
|
||
|
|
code may not run on older Windows releases then. My Windows 2000
|
||
|
|
box was not able to run the code, for example. The situation is
|
||
|
|
slightly confusing because
|
||
|
|
<https://docs.microsoft.com/en-us/windows/desktop/api/ws2tcpip/nf-ws2tcpip-getaddrinfo>
|
||
|
|
suggests that getaddrinfo should be available on all Windows
|
||
|
|
releases. */
