Hi,
Test cases unshare failed to compile on systems without such a
syscall. I am unsure what the best way to handle it. The old ways are,
* add a kernel version check in the unshare tests code.
or
* add a m4 rule.
* modify the unshare tests code to check if the macro, and add stub
functions if the macro is false.
The first approach is unable to handle non-vanilla kernels. The second
approach needs to add stub functions which are unclean. What I would
like to do is,
* add a m4 rule.
* modify unshare Makefile like this,
ifdef HAVE_UNSHARE <-- if the syscall is present, compile the tests.
CFLAGS += -I../../../../include -Wall
LDLIBS += -L../../../../lib -lltp
SRCS = $(wildcard *.c)
TARGETS = $(patsubst %.c,%,$(SRCS))
all: $(TARGETS)
install:
@set -e; for i in $(TARGETS); do ln -f $$i ../../../bin/$$i ; done
else <-- Otherwise, skip them.
all:
However, I am not sure how to pass the HAVE_UNSHARE value to the
Makefile yet.
