Can't build on freebsd about monsterwm HOT 6 CLOSED

there have been people that built monsterwm on DragonFly and Free BSD.
See the posts here and here.
as noted, pkgconfig can help you locate the correct paths.

from monsterwm.

X11INC = -I/usr/local/include/X11
X11LIB = -L/usr/local/lib -lX11

INCS = -I. -I/usr/local/include ${X11INC}
LIBS = -L/usr/local/lib -lc ${X11LIB}

it is not quite what you post for freebsd 9 but I get this:

monsterwm build options:
CFLAGS   = -std=c99 -pedantic -Wall -Wextra -I. -I/usr/local/include -I/usr/local/include/X11 -DVERSION="cookies-git" -Os
LDFLAGS  = -L/usr/local/lib -lc -L/usr/local/lib -lX11 -s
CC       = cc

CC -o monsterwm

Is it building properly? or should I do excatly as you posted?

from monsterwm.

The build should be fine.
The warnings is generated by Xfuncproto.h line 145, where it uses named variadic macros.
C99 provides a way to use n.v.m. properly through __VA_ARGS__ [ref].

The warning may go away by using -std=gnuc instead of -std=c99 in CFLAGS.

from monsterwm.

error: invalid value 'gnuc' in '-std=gnuc'

I thing it is because FreeBSD used Clang/llvm from version 10.
any work around?

from monsterwm.

right, sorry, that should be gnu99 [ref]

from monsterwm.

for clang the same applies [ref]

clang supports the -std option, which changes what language mode clang uses. The supported modes for C are c89, gnu89, c94, c99, gnu99 and various aliases for those modes. If no -std option is specified, clang defaults to gnu99 mode.
