Summary:                    Buildroot compilation is broken for SH4 architecture
Description: 
I am unable to do a build for the SH4 architecture.

Steps to reproduce:
  - do a clean checkout/update (rev 19264)
      svn://uclibc.org/trunk/buildroot
  - rm .config*             (just to make sure)
  - make menuconfig
      Select superh and SH4 architecture
      Select uClibc 0.9.29  (instead of the snapshot)
      Select cramfs as the root fs
  - make

Note: 
  The binutils were never build. It started immediately with GCC-4.2.1

-------------------------------------------------------------

It looks like the error indicates to the fact that the kernel headers
where
never compiled/copied to their correct place.  Seems like a dependency is
missing for kernel-headers and binutils.

---------------------------------------------------------------------- 
This is not just with GCC4.2.1. I am using latest Buildroot snapshot of
250707 & building arm926 toolchain with uClibc 0.9.29 with GCC-4.2.0 & i
am facing the same issue. This started for me since Buildroot Snapshot
240707. At present Buildroot snapshot of 230707 works fine

 

---------------------------------------------------------------------- 
 bernhardf - 07-27-07 09:18  
---------------------------------------------------------------------- 
This should be fixed as of r19285. Please confirm. 

---------------------------------------------------------------------- 
 fgretief - 08-01-07 14:34  
---------------------------------------------------------------------- 
I can confirm that the dependency fix works.  The build get much further
but there is still a number of breakages:

 (1) The uClibc configuration waits for user input at the 'Target
Processor Type' question (see below).  It continues as soon as you press
enter. 

*
* Target Architecture Features and Options
*
Target Processor Type
  1. SH2A (CONFIG_SH2A) (NEW)
  2. SH2 (CONFIG_SH2) (NEW)
  3. SH3 (CONFIG_SH3) (NEW)
> 4. SH4 (CONFIG_SH4) (NEW)
choice[1-4?]:                   




 (2) uClibc gets configured to build a big endian library, even though I
selected little endian. See errors below. 
The problem lies in the 'toolchain/uClibc/uclibc.mk' file were the SH is
missing two lines. The patch below fixes the
problem for me.

 (3) Patch 'uClibc-0.9.29-001-fix-mmap.patch' is a problem.  It uses a
type '__ulong_t' that is not defined and causes a compile error. See error
below. If I replace the type with 'unsigned long' or even '__u_long' then
it works.

Error 2




 (4) While linking BusyBox, the linker is unable to find the
sched_getaffinity and sched_setaffinity functions.  There is a patch
'uClibc-0.9.29-conditional-sched_affinity.patch' that comment out a piece
of the relevant source file. Don't know if it is related to this error.  I
modified the busybox config file (see diff below) to unset the
CONFIG_TASKSET function.  This removes the functionality from BusyBox and
allow the build to continue. Not ideal if you need that functionality.
Propper fix is required.

--------------------

You need to add a "-" to the following line:
$(STRIP) --strip-unneeded $(TARGET_DIR)/lib/libgcc_s*
making it look like:
--------------------
	#
	# Ok... that's enough of that.
	#
	-mkdir -p $(TARGET_DIR)/usr/lib $(TARGET_DIR)/usr/sbin
	touch $@

$(GCC_BUILD_DIR2)/.libs_installed: $(GCC_BUILD_DIR2)/.installed
ifeq ($(BR2_GCC_SHARED_LIBGCC),y)
	# These are in /lib, so...
	rm -rf $(TARGET_DIR)/usr/lib/libgcc_s*.so*

$(TARGET_DIR)/lib/
	-$(STRIP) --strip-unneeded $(TARGET_DIR)/lib/libgcc_s*
--------------------

Then it will build a working toolchain :)

Thank to mastag's suggestion, I am now able to compile buildroot for the SH
architecture. Below is a patch against r19690 that compiles with gcc 4.2.1
and gcc 3.4.6 for the following targets: sh4, sh4eb, sh3, sh3eb and sh2.
Currently only Linux and Busybox were compiled.
