[Bug 20314] New: wine loader doesn't work on Debian/kFreeBSD
http://bugs.winehq.org/show_bug.cgi?id=20314 Summary: wine loader doesn't work on Debian/kFreeBSD Product: Wine Version: 1.1.31 Platform: PC URL: http://www.debian.org/ports/kfreebsd-gnu/ OS/Version: FreeBSD Status: NEW Keywords: download, source Severity: critical Priority: P2 Component: loader AssignedTo: wine-bugs(a)winehq.org ReportedBy: austinenglish(a)gmail.com Found out about the debian/FreeBSD port, so I gave it a spin. Wine mostly compiles, with a couple warnings (I'll send a patch in a bit), but the killer is loader/preloader.c. It's disabled on FreeBSD normally, by configure.ac: case $host_cpu in *i[[3456789]]86*) case $host_os in linux* | k*bsd*-gnu) AC_SUBST(EXTRA_BINARIES,"wine-preloader") ;; esac ;; esac but the k*bsd*-gnu enables it here. The problem is, preloader.c has some linux specific stuff: static inline int wld_prctl( int code, int arg ) { int ret; __asm__ __volatile__( "pushl %%ebx; movl %2,%%ebx; int $0x80; popl %%ebx" : "=a" (ret) : "0" (SYS_prctl), "r" (code), "c" (arg) ); return SYSCALL_RET(ret); } The SYS_prctl is Linux specific, see: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=550435 I tried removing the k*bsd*-gnu from configure.ac, but the loader still doesn't work: wine: failed to initialize: /usr/local/lib/wine/ntdll.dll.so: failed to map segment from shared object: Cannot allocate memory -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

My guess is that you'll have to fix it yourself, since probably very few developers use GNU/kFreeBSD at this time. You can look to dlls/kernel32/process.c (set_process_name) for inspiration about what the prctl's function (and BSD equivalent?) is. However, you can't just copy that code into the preloader, since the preloader may not depend on *any* userspace library, not even libc or ldso. It has to do direct kernel syscalls for anything it needs to do. Probably only someone with experience with FreeBSD would know how to add such syscalls. (Though perhaps it's fine to just ifdef out the whole prctl thing? Its purpose looks quite cosmetic.) -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Hi Austin. My guess is that you'll have to fix it yourself, since probably very few developers use GNU/kFreeBSD at this time.
I don't think I'll have time to do so either, especially since I'm not terribly familiar with the FreeBSD kernel. I wanted to get a bug filed so it's not forgotten about. Besides, maybe someone will get bored and fix it :-).
You can look to dlls/kernel32/process.c (set_process_name) for inspiration about what the prctl's function (and BSD equivalent?) is.

Right. As time permits, I'll play around with it a bit, but don't expect anything fruitful to come out of it.

I tried that, still failed. Perhaps with a few more ifdef/elseif's it may be easy to get a working loader... -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
