[oe] Preferred gcc version ignored

[Pascal Kesseli]

Hi everyone

 

Recently, I tried building helloworld without providing a precompiled
toolchain for the MOXA UC-7408+. It worked as expected with OpenEmbedded
first compiling the cross-compiler and glibc. To do so, I used the following
machine config:

 

TARGET_ARCH = arm

PACKAGE_ARCH = xscale

TARGET_CC_ARCH = "-mcpu=xscale"

#ASSUME_PROVIDED += virtual/arm-linux-gcc virtual/libc

PREFERRED_PROVIDER_virtual/kernel = "linux-2.6"

BOOTSTRAP_EXTRA_DEPENDS += " virtual/kernel"

BOOTSTRAP_EXTRA_RDEPENDS += " kernel kernel-modules"

IMAGE_FSTYPE = "ext2"

EXTRA_IMGECMD_ext2 = " -b 2097152"

 

PREFERRED_PROVIDER_virtual/arm-linux-libc-for-gcc = glibc

PREFERRED_VERSION_arm-linux-gcc = "3.4.4"

PREFERRED_VERSION_gcc = "3.4.4"

PREFERRED_VERSION_gcc-cross = "3.4.4"

PREFERRED_VERSION_glibc = "2.3.3"

 

 

Nevetheless, the compilation failed with the following error:

It seems as if gcc version 4.2.4 was created and used by OpenEmbedded, which
is too new for building glibc 2.3.3. Which PREFERRED_VERSION statement did I
miss to advise OpenEmbedded to use an earlier gcc version to build the
glibc?

 

Thanks for any help and best regards
