/bin/sh: llvm-config : commande introuvable

pacaur -S llvm

make: *** No rule to make target `/usr/include/stdc-predef.h', needed by` packer.o'. Stop.

Remove the lines below DO NOT REMOVE in the makefile, or update it with make depend.

/usr/include/glib-2.0/glib/gtypes.h:34:24: fatal error: glibconfig.h: No such file or directory

Replace the static end of INCLUDES line in the Makefile by

`pkg-config --cflags glib-2.0`

If you don't have the pkg-config executable, replace with correct location

qemu/rules.mak:33: recipe for target 'coroutine-ucontext.o' failed

error: ‘INDEX_op_qemu_st8’ undeclared (first use in this function)

With new qemu the TCG operations may change their names, so comment out the line and make again.

While making nrop: g++: error: qemu/trace/default.o: No such file or directory

Welcome to Sparta. the QEMU_ALL variable in the Makefile is a dirty step to link against all qemu objects. Some will be deleted from qemu and have to be removed in QEMU_ALL. Others have to be added and will appear as

undefined reference to `qapi_event_send_block_job_error'

You thus have to include the new object file in the QEMU_ALL variable. The current version was built again qemu commit :

commit e9d818b8b1a7fadc6c92256b716f1bc21b8daabc

If you are brave enough, you can feed the QEMU_ALL variable with the output of find qemu/ -name "*.o" | awk '{print}' ORS=' '

Yes I am

Ok,

find qemu/ -name "*.o" | awk '{print}' ORS=' '
# Out conflicts
make 2>&1 | grep "In function" | awk '{ print $1 }' | uniq | awk '{print substr($0, 0, length($0))}' ORS='|'
find qemu/ -name "*.o" | egrep -v "($_)" | awk '{print}' ORS=' '

I think qemu/x86*/linux-user/main.o is filtered, so add it manually. Then for each undefined

grep -Rni vmstate_register_with_alias_id qemu # to find multiple references
# Remove the module from QEMU_ALL

Something about jit_register_code happens, replace __jit by __jat in qemu/tcg/tcg.c.

 end

Note that the call now use the raise_exception name and not tmp11, thus I filter on call for now. I will do the same for pause and raise_interrupt. The INDEX_op_call handling in qemu/tcg/tcg.c is different with qemu2.X and I imported the new tcg_find_helper.
