Thanks for testing. I compile in the directory "groff/build". I have two branches, my own and master. The error is in my branch. It is caused by having simultaneously CFLAGS='-O...' and CPPFLAGS=-D_FORTIFY_SOURCE=2 Changing the value from 2 to 0 or 1, eliminates the error. My version of glibc is 2.31-13 (Debian, testing). As Debian uses both '-O2' and "-D_FORTIFY_SOURCE=2" for its compilation, a fix seems to be necessary. ### In the master branch I get, with the default output from "configure", this CC src/devices/xditview/gxditview-page.o In file included from /usr/include/X11/Xos.h:89, from ../src/devices/xditview/page.c:7: ./lib/unistd.h:663:3: error: #error "Please include config.h first." 663 | #error "Please include config.h first." | ^~~~~ ./lib/unistd.h:665:24: error: expected ';' before 'extern' 665 | _GL_INLINE_HEADER_BEGIN | ^ | ; ./lib/unistd.h:2815:22: error: expected ';' before 'struct' 2815 | _GL_INLINE_HEADER_END | ^ | ; make[1]: *** [Makefile:7219: src/devices/xditview/gxditview-page.o] Error 1 make[1]: Leaving directory '/home/bg/git/groff/build' In my branch I have added the missing '#include "config.h"' in ../src/devices/xditview/page.c and other missing "config.h" lines in other source files. -- Bjarni I.
