Toolchain select

Toolchain select

[Li Weichen]

Hi all,

I encountered several toolchain problems while cross-compiling such as
u-boot, kernel.  I find it mostly problem about the version.  I don't know
which one is proper and stable for embedded system developing.  Could you
please help me?

I have already used the crosstool to make my own toolchain, and chose the
gcc-4.0.1, binutils-2.16.1, glibc-2.3.5.  But it seems that it has some
problem.  When I build u-boot it shows that the examples cannot be compiled.

	u-boot may not be a good test.  Versions of u-boot older than 1.1.4 do
not compile with 4.0 at all; even 1.1.4 seems to have problems, as some
users have reported that it does not compile (most seem to be OK, but
there are a few who cannot).  You said that kernel did not compile
either, though, and that should work, so the problem in your case likely
lies with the toolchain.

	My toolchain was compile with gcc-4.0.1, binutils-2.15 and glibc 2.3.5:
this combination is known to work.  Looking at the crosstool buildlogs,
your combination is not listed, so it is somewhat of an unknown
quantity, though it sounds like the combination you have picked does not
work.  I would recommend looking at the crosstool buildlogs yourself, to
see what combinations are known to work, and sticking with them, unless
you want to experiment with different combinations.

Hi Wolfgang,

I have tried the ELDK 3.1.1, and when I build u-boot-1.1.3 or u-boot-1.1.4 I
get following error:

iaadoa at omap1:~/work/tmp/u-boot-1.1.3$ make omap5912osk_config
Configuring for omap5912osk board...
iaadoa at omap1:~/work/tmp/u-boot-1.1.3$ make all
make[1]: Entering directory `/home/iaadoa/work/tmp/u-boot-1.1.3/tools'
 [.]
make[1]: *** No rule to make target `hello_world.srec', needed by `all'.
Stop.
make[1]: Leaving directory `/home/iaadoa/work/tmp/u-boot-1.1.3/examples'
make: *** [examples] Error 2

I have met this error for quite a time, and I have tried different versions
of toolchain, but it seems to be the same.  Can you help me with it?

Thanks and best regards!

RE: Toolchain select

[Li Weichen]

Well, if I use the toolchain consists of gcc-4.0.1, binutils-2.15,
glibc-2.3.5 to build u-boot and the kernel 2.6.15-omap1, I will still get
errors.  The error of building u-boot is "No rule to make target
`hello_world.srec', needed by `all'" and the error of building kernel
2.6.15-omap1 is syntax error in touchscreen.

I don't know where is the problem.

omap5912osk board support is obviously broken. I wonder that you  get
as  far as the examples directory - I see problems with messing flash
functions earlier.

I read part of it all the way through.

	That is a make error, not a toolchain one: make does not have a rule to
make the said file, and so does not know what to do.  That likely
indicates that it is a file that either should already be there, or
created by an earlier process (eg running 'make something_config' type
operations).  In this case, I can see the file in my examples/
directory, so likely there is something wrong with your process.  Make
sure you have followed the steps for compiling u-boot correctly, as you
do not compile it the same as with most programs.

RE: Toolchain select

[Li Weichen]

Hi,

What version of u-boot are you using?  I use the u-boot-1.1.4 and
u-boot-1.1.3, and my steps is,
$tar xjvf u-boot-1.1.x
$cd u-boot-1.1.x
$make omap5912osk_config
$make

I think there is nothing wrong in my process.

And have you tried building the 2.6.15 kernel?

	I am using 1.1.2; I have 1.1.4, but it does not link (I have not
investigated why yet, as it is pretty low priority).

	Your process is correct, so it is a little strange that the file does
not exist.  The command which creates the file (as called from the
Makefile) is:
	arm-linux-objcopy -O srec hello_world hello_world.srec 2>/dev/null
	I would suggest looking for where that command is used when you run it,
for there is likely a minor error being flagged at this point (run make
distclean first, then start afresh).

> And have you tried building the 2.6.15 kernel?

	Not yet: it is not on my current list of priorities.  I am running
2.6.14-omap1 at the moment.

[Li Weichen]

Thank you for your kind reply I think there is something wrong with the
omap5912osk_config file.  And the 2.6.14 kernel is no problem,  but the
2.6.15 can not work here.

Thanks again and best regards.

You may look at http://www.kegel.com/crosstool/crosstool-0.38/buildlogs/ 
which is a matrix of possible working tool combo's
