Hi all,
I am new to this list, and have been using fink for a while now (And
have been using Debian for years, so it is all pretty familiar to me).
I had a go at building emacs21 with the closest match I could see in
etc/MACHINES being NeXT, and I needed to make a number of changes to the
source. But I am having problems in the last stages of compiling.
LC_ALL=C ./temacs -batch -l loadup dump
Consumes all memory and brings darwin to a grinding halt.
The changes I made were to dispnew.c and unexnext.c
dispnew.c : The FILE struct is different from GNU libs and the other
alternative as used in the PENDING_OUTPUT_COUNT macro, but I think I
defined a correct one using the OSX headers as a reference.
#define PENDING_OUTPUT_COUNT(FILE) ((FILE)->_p - (FILE)->_bf._base)
unexnext.c : The undocumented vm_region function (Except in the headers)
effects the get_data_region function.
I added these vars:
vm_region_info_t vm_region_info;
vm_region_flavor_t vm_region_flavor;
mach_msg_type_number_t mach_msg_type_number;
.. and the call to vm_region was changed to:
ret = vm_region(current_task(),
®ion.address,
®ion.size,
&vm_region_flavor,
&vm_region_info,
&mach_msg_type_number,
®ion.object_name);
if (ret != KERN_SUCCESS || region.address >=
VM_HIGHDATA) {
break;
}
//Darwin(Mach's) vm_region differs
//TODO! Fix this to detect darwin in the build.
region.protection = vm_region_info[0];
region.max_protection = vm_region_info[1];
region.inheritance = vm_region_info[2];
region.shared = vm_region_info[3];
region.offset = vm_region_info[5];
I also needed to use current_task() in place of an undefined function.
I had some problems with libraries too, so I messed with LIBES in
src/Makefile adding -lSystem.B -ltcl
(Whats the equiv of ldd in Darwin? I have had some success with nm, but
not the nice clean output of ldd)
I wonder if anyone else has had better luck.
I can provide patches for what I have done, but its a bit crude at the
moment and doesn't work.
PS: I have tried a couple of Carbon emacs ports and none have been very
stable. I am currently using emacs20 in X11 which is perfect.. but I
like using emacs21 better and have been on Debian with alpha releases
for a while.
