Hi,
I recently reinstalled my system, now on Fedora (version 36) rather than
Ubuntu. I tried cross-compiling LilyPond for MinGW, to continue
investigating
https://gitlab.com/lilypond/lilypond/-/issues/6361. However, Ghostscript
fails to compile with
In file included from
/home/jean/repos/lilypond/release/binaries/mingw/dependencies/src/ghostscript-9.56.1/base/gp_unix.c:24:
/home/jean/repos/lilypond/release/binaries/mingw/dependencies/src/ghostscript-9.56.1/base/time_.h:82:12:
fatal error: sys/times.h: No such file or directory
82 | # include <sys/times.h>
| ^~~~~~~~~~~~~
compilation terminated.
The code in question reads
#if defined(HAVE_SYS_TIMES_H) && HAVE_SYS_TIMES_H == 1
# include <sys/times.h>
# define use_times_for_usertime 1
/* Posix 1003.1b-1993 section 4.8.1.5 says that
CLK_TCK is obsolescent and that sysconf(_SC_CLK_TCK)
should be used instead, but this requires including
<unistd.h>, which is too painful to configure. */
# ifndef CLK_TCK
# define CLK_TCK 100 /* guess for older hosts */
# endif
#else
# define use_times_for_usertime 0
#endif
As far as I understood, it's expected that MinGW doesn't have
sys/times.h. The question is thus why HAVE_SYS_TIMES_H was 1.
Looking into mingw/dependencies/build/ghostscript-9.56.1/config.log,
I find

That sounds odd. I'm a bit out of my depth here. Does anyone have
a clue?
Also, Fontconfig failed building before I did

(the linker error was about __strcpy_chk).
I have no idea why this is needed. Grepping for "FORTIFY_SOURCES"
in the Fontconfig repository doesn't yield matches. Again, can
anyone shed light on this?
Thanks for your patience.
