[Asterisk-Dev] Zaptel compile error after kernel switch to SMP

[David Cook]

Not sure if this is a recent HEAD issue, kernel change or RHEL thing.

After moving from RHEL3 uniprocessor kernel to SMP kernel and looking to
rebuild *, zaptel Makefile fails to correctly determine KSRC.

This might have something to do with how RH changed the source locations
recently. Plus there appears to be a shell error with $ vs. $$ in a
conditional statement.

Seems to stem from the contents of /lib/modules/`uname -r`/build/include
not containing full include headers but /usr/src/linux-2.4/include
does.

Here is the top of hacked Makefile with some comments.

#

HOSTCC=gcc
# If you want to build for a kernel other than the current kernel, set
KVERS
ifndef KVERS
KVERS:=$(shell uname -r)
endif
ifndef KSRC
  #ifneq (,$(wildcard /lib/modules/$(KVERS)/build)) <-- comment
  ifeq (,$(wildcard /lib/modules/$(KVERS)/build)) <-- eq vs. neq
    KSRC:=/lib/modules/$(KVERS)/build
  else
    KSRC_SEARCH_PATH:=/usr/src/linux-2.4 /usr/src/linux
    #KSRC:=$(shell for dir in $(KSRC_SEARCH_PATH); do if [ -d $$dir ];
then echo $dir; break; fi; done) <-- commend
    KSRC:=$(shell for dir in $(KSRC_SEARCH_PATH); do if [ -d $$dir ];
then echo $$dir; break; fi; done) <-- "echo $dir" change to "echo
$$dir"
  endif
endif
KINCLUDES:=$(KSRC)/include
