HI,

In my experience .. it is always just the version, not the package that

PREFERRED_VERSION_gcc = "gcc_4.6"
PREFERRED_VERSION_gcc-cross = "gcc-cross_4.6"
PREFERRED_VERSION_gcc-cross-initial = "gcc-cross-initial_4.6"

PREFERRED_VERSION_gcc-runtime = "gcc-runtime_4.6"
PREFERRED_VERSION_libgcc = "libgcc_4.6"

If I set the values as follows:

PREFERRED_VERSION_gcc = "4.5"
PREFERRED_VERSION_gcc-cross = "4.5"
PREFERRED_VERSION_gcc-cross-initial = "4.5"
PREFERRED_VERSION_gcc-cross-intermediate = "4.5"
PREFERRED_VERSION_gcc-cross-canadian = "4.5"
PREFERRED_VERSION_gcc-crosssdk= "4.5"
PREFERRED_VERSION_gcc-crosssdk-initial= "4.5"
PREFERRED_VERSION_gcc-crosssdk-intermediate= "4.5"
PREFERRED_VERSION_gcc-runtime = "4.5"
PREFERRED_VERSION_libgcc = "4.5"

I get the following warnings:

NOTE: preferred version 4.5 of gcc not available (for item gcc)
NOTE: versions of gcc available: 4.5.4+svnr189152 4.6.3+svnr184847

You need wildcards:

PREFERRED_VERSION_gcc = "4.5%"

So it will match on 4.5.4+svnr189152, which is the actual version of
the 4.5 toolchain you have available.

I've now got 3 gcc variants, 4.7 (in poky), 4.6 and 4.5 (in
meta-openembedded), and it's automatically picking up 4.6, from the
meta-openembedded/toolchain-layer.

After gcc_4.6 recipe builds, and I attempt to re-run gcc_4.5, I get the
following output:

elvis@eos:/tool/yocto/poky/build$


At this stage, 4.7.1, 4.6.3 have been built, but it doesn't allow me to
build gcc_4.5 recipe.
