Hi Everyone,I'm trying to build Emacs on Cygwin. I use the platform as a test bed because of Newlib. Emacs is failing with: gcc -DHAVE_CONFIG_H -I. -I../lib -I../src -I../src -I/usr/local/include -DNDEBUG -pthread -D_XOPEN_SOURCE=600 -m64 -MT close-stream.o -MD -MP -MF .deps/close-stream.Tpo -c -o close-stream.o close-stream.c In file included from /usr/include/sys/signal.h:22:0, from /usr/include/signal.h:6, from ./signal.h:52, from ./sys/select.h:107, from /usr/include/sys/time.h:47, from ./sys/time.h:39, from ./sys/select.h:86, from /usr/include/sys/types.h:68, from ./sys/types.h:28, from ./fcntl.h:50, from binary-io.h:23, from binary-io.c:3: /usr/include/cygwin/signal.h:175:3: error: unknown type name ‘pthread_attr_t’ pthread_attr_t *sigev_notify_attributes; /* notification attributes */ ^~~~~~~~~~~~~~ Examining /usr/include/cygwin/signal.h around 175, I see: typedef struct sigevent { sigval_t sigev_value; /* signal value */ int sigev_signo; /* signal number */ int sigev_notify; /* notification type */ void (*sigev_notify_function) (sigval_t); /* notification function */ pthread_attr_t *sigev_notify_attributes; /* notification attributes */ } sigevent_t; But I don't see an include for the pthread gear in the signal.h header file. I found one past message that's similar (https://cygwin.com/ml/cygwin/2016-06/msg00458.html), but its reported as an upstream bug.
Yes, it was an upstream gnulib issue that was fixed long ago. I suspect you're building an old version of emacs that hadn't yet imported the fixed gnulib. Try building the latest emacs release. It should build with a simple ./configure && make.
