Hi Tim, Thanks for details. I'll fix this case.
However, it is not advisable to use any -Werror= flags for configure, as it may break some tests. For example, if you will use -Werror=extra-semi clang flag then you will break most of compile and link tests. I'd recommend you to run configure without any -Werror flags, but redefine CGLAGS with -Werror parameters for make invocation. -- Wishes, Evgeny 29.05.2019 12:45, Tim Rühsen wrote: > On 5/28/19 9:07 PM, Evgeny Grin wrote: >> On which system did you test it? >> Looks like MHD_FEATURE_AUTODETECT_BIND_PORT is not available on you OS, >> which is pretty strange as it should works on all modern platforms. >> > MHD_config.h: > /* Define if you have usable `getsockname' function. */ > /* #undef MHD_USE_GETSOCKNAME */ > > config.log: > configure:18603: checking whether getsockname is declared > configure:18603: result: yes > configure:18629: checking for getsockname > configure:18629: result: yes > configure:18635: checking whether getsockname() is usable > ... > conftest.c: In function 'main': > conftest.c:165:3: error: implicit declaration of function 'close' > [-Werror=implicit-function-declaration] > 165 | close (sckt); > | ^~~~~ > conftest.c:165:3: warning: nested extern declaration of 'close' > [-Wnested-externs] > cc1: some warnings being treated as errors > configure:18730: $? = 1 > configure: program exited with status 1 > configure:18742: result: no > > > I am using > $ gcc-9 --version > gcc-9 (Debian 9.1.0-1) 9.1.0 > > with a lot of warning flags - though I don't use -Werror explicitly. > > It's your configure.ac code that doesn't play well here. > Why are you not just using "AC_CHECK_FUNCS([getsockname])" ?
