From c82db690cc0c4624dad4dc6ae899020799ec84db Mon Sep 17 00:00:00 2001 From: Hiltjo Posthuma Date: Fri, 3 Apr 2020 15:36:32 +0200 Subject: [PATCH] config.mk: fix POSIX_C_SOURCE macro for feature test for snprintf() The feature test was incorrect: _POSIX_C_SOURCE=2 "The value 2 or greater additionally exposes definitions for POSIX.2-1992." http://man7.org/linux/man-pages/man7/feature_test_macros.7.html A higher value is needed (atleast 1995): https://pubs.opengroup.org/onlinepubs/9699919799/functions/snprintf.html FreeBSD feature test macro: on https://github.com/freebsd/freebsd/blob/master/include/stdio.h line 297 This was already fixed in dmenu. This fixes a warning on FreeBSD, reported by Plasmoduck on IRC, thanks. --- config.mk | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/config.mk b/config.mk index 6d36cb7..7084c33 100644 --- a/config.mk +++ b/config.mk @@ -25,7 +25,7 @@ INCS = -I${X11INC} -I${FREETYPEINC} LIBS = -L${X11LIB} -lX11 ${XINERAMALIBS} ${FREETYPELIBS} # flags -CPPFLAGS = -D_DEFAULT_SOURCE -D_BSD_SOURCE -D_POSIX_C_SOURCE=2 -DVERSION=\"${VERSION}\" ${XINERAMAFLAGS} +CPPFLAGS = -D_DEFAULT_SOURCE -D_BSD_SOURCE -D_POSIX_C_SOURCE=200809L -DVERSION=\"${VERSION}\" ${XINERAMAFLAGS} #CFLAGS = -g -std=c99 -pedantic -Wall -O0 ${INCS} ${CPPFLAGS} CFLAGS = -std=c99 -pedantic -Wall -Wno-deprecated-declarations -Os ${INCS} ${CPPFLAGS} LDFLAGS = ${LIBS}
