Subject: clang fails to compile emacs in Microsoft Windows
Date: Fri, 12 May 2023 19:41:17 +0530 [thread overview]
Message-ID: <CALK-3mKqRtZ7budD0+YbAJtaW3DeEWtwmHAtncB4vsSUq_yj1g@mail.gmail.com> (raw)
* compiler:
clang version 16.0.2
Target: x86_64-w64-windows-gnu
Thread model: posix
* compiler error:
../../src/sysdep.c:472:13: error: call to undeclared function
'waitpid'; ISO C99 and later do not support implicit function
declarations [-Wimplicit-function-declaration]
../../src/sysdep.c:518:43: error: use of undeclared identifier 'WNOHANG'
* Probable reason:
AC_HEADER_SYS_WAIT fails to check sys/wait.h file. It tests with
wait() function which is undefined in nt/inc/sys/wait.h file. Here is
the error message from config.log
configure:11452: checking for sys/wait.h that is POSIX.1 compatible
configure:11479: x86_64-w64-mingw32-cc -I ../nt/inc -c -g3 -O2
-gdwarf-2 -mtune=generic -D__USE_MINGW_ANSI_STDIO=1 conftest.c >&5
conftest.c:70:3: error: call to undeclared function 'wait'; ISO C99
and later do not support implicit function declarations
[-Wimplicit-function-declaration]
I can provide further information if required. Thank you.
