* The AC_LANG_PROGRAM macro adds the `main()` so it is erroneous to add it to the test program. * This was detected with the XL compilers which will fail to build the program in this situation. The GNU compiler does not error out or warn, but successfully compiles the program. Signed-off-by: Joshua Hursey <jhursey@us.ibm.com>

# (e.g., Fedora 9), where the function is defined and you can
|
|
# link against it, but it's hardwired to return ENOSYS -- and
|
|
# /usr/include/gnu/stubs.h fails to define __stub_epoll_ctl
|
|
# (the usual mechanism in glibc to indicate that a function is
|
|
# a stub and isn't really implemented). Hence, checking for
|
|
# the symbol succeeds because it thinks it can use epoll_ctl
|
|
# (and friends). So we have to do an actual test after we
|
|
# determine that epoll_ctl is linkable. Grumble. If we are
|
|
# cross compiling, all we can do is trust AC_CHECK_FUNCS and
|
|
# pray.
|
|
|
|
# Unfortunately, there's also another potential
|
|
# incompatibility. The event_poll struct is defined in the
|
|
# sys/epoll.h file. The structure is the interface between
|
|
# the application and the kernel and is therefore compiled
|
|
# into both. The event_poll struct is defined with a compiler
|
|
# directive __attribute__ ((__packed__). It turns out that
|
|
# there is at least one compiler (Sun Studio) that does not
|
|
# currently recognize this directive. This means that the
|
|
# event_poll struct may be packed in the kernel, but not in
|
|
# the libevent library. Badness ensues. Therefore, check to
|
|
# see that this struct gets correctly passed between userspace
|
|
# and the kernel.
|

|
|
# In this test, we use epoll in Level Triggered mode. We create

# a pipe and the write only file descriptor of the pipe is
