- The header file layout has been cleaned up, mostly in terms of the
sys/select.h, sys/signal.h and sys/types.h files. This is a generic
change in newlib and aligns the affected headers more closely to
the FreeBSD layout.
These changes are leading to lots of errors when building emacs:
/usr/include/cygwin/signal.h:178:3: error: unknown type name ‘pthread_attr_t’
/usr/include/cygwin/signal.h:213:3: error: unknown type name ‘pid_t’
/usr/include/cygwin/signal.h:230:2: error: unknown type name ‘timer_t’
/usr/include/sys/signal.h:211:6: error: #error You need the winsup sources or a
cygwin installation to compile the cygwin version of newlib.
/usr/include/sys/signal.h:214:5: error: unknown type name ‘pthread_t’
/usr/include/sys/time.h:104:34: error: unknown type name ‘u_int’
[... and many more]
This puzzles me. It looks like you're missing sys/types.h when
including sys/signal,h, but sys/signal.h includes sys/types.h by
itself, prior to including cygwin/signal.h.
How can I reproduce this? An STC like this:
#include <signal.h>
main () {}
is definitely not sufficient.
Sorry, I hadn't looked at what was happening closely enough before
sending my mail. The errors occur while compiling some Gnulib modules
in the emacs source tree. It may take me a while to sort this out.
Maybe Gnulib will have to be patched to take Cygwin's new header layout
into account.
