Re: [Ltib] ltib not installing the cross compiler.

[Stuart Hughes]

Hi Glenn,

>From the output it looks as though a cross compiler got install.
However maybe there's a problem with the referencing paths.

First of all, I've not been involve with this particular BSP, nor is it
even part of the public LTIB project.  However here's some things to
look at:

* check the cross compiler got installed:

/opt/freescale/ltib/usr/bin/rpm -qi gcc-4.3.3-glibc-2.8-cs2009q1-203-1

This may have an entry called Relocations: which will show the install
path.

* check the actually files installed (you could grep for
arm-none-linux-gnueabi-gcc)

/opt/freescale/ltib/usr/bin/rpm -ql gcc-4.3.3-glibc-2.8-cs2009q1-203-1


If this looks okay, what is supposed to tie-up is the entry in the
defconfig for that platform and these paths (or the .config once you're
run it).

To find out you BSP run:

$ cat .config | grep CONFIG_PLATFORM_DIR

and then grep for the toolchain entries:

grep ^CONFIG_TOOLCHAIN <config_dir>/.config

mine shows (for a different platform):

CONFIG_TOOLCHAIN_E300_GLIBC2=y
CONFIG_TOOLCHAIN="freescale-powerpc-linux-gnu-4.3-74.i686.rpm"
CONFIG_TOOLCHAIN_PATH="/opt/freescale/usr/local/gcc-4.3.74-eglibc-2.8.74/powerpc-linux-gnu"
CONFIG_TOOLCHAIN_PREFIX="powerpc-linux-gnu-"
CONFIG_TOOLCHAIN_CFLAGS=""


What the ltib script does to test the toolchain installation is to look for:

$CONFIG_TOOLCHAIN_PATH/bin/${CONFIG_TOOLCHAIN_PREFIX}-gcc

So in my example:

/opt/freescale/usr/local/gcc-4.3.74-eglibc-2.8.74/powerpc-linux-gnu/bin/powerpc-linux-gnu-gcc


If there's a mismatch then it seems like there's a BSP packaging error.
     At that point ask the BSP vendor to provide a fix.  To fix it
yourself would mean editing config/userspace/toolchain.lkc, which
unfortunately is a bit hard to understand.  In my case you'd look in
that file for
TOOLCHAIN_E300_GLIBC2 (e.g. remove the CONFIG_) and find the places
where the path/prefix are set and correct them.

Regards, Stuart
