[Buildroot] Build Fails with ruby-1.9.2-p0

[Christopher Boumenot]

I am trying to create a minimal x86 root image that includes ruby-1.9.2-p0,
but the build fails when compiling ruby.

/home/boumenot/src/buildroot-2011.05/output/build/ruby-1.9.2-p0/lib/mkmf.rb:365:in
`try_do': The complier failed to generate an executable file. (RuntimeError)
You have to install development tools first.

/home/boumenot/src/buildroot-2011.05/output/build/ruby-1.9.2-p0/lib/mkmf.rb:446:in
`try_compile'
        from
/home/boumenot/src/buildroot-2011.05/output/build/ruby-1.9.2-p0/lib/mkmf.rb:496:in
`try_static_assert'
        from ../.././ext/bigdecimal/extconf.rb:5
        from ./ext/extmk.rb:156:in `load'
        from ./ext/extmk.rb:156:in `extmake'
        from ./ext/extmk.rb:445
        from ./ext/extmk.rb:441:in `each'
        from ./ext/extmk.rb:441
make: *** [mkmain.sh] Error 1

Here's the code that the ruby build process was trying to build.

This is against buildroot-2011.05.  I am building on OpenSuSE v11.4
x86_64 targeting x86.  I am using the default toolchain values for this
version of buildroot.  I am not sure what other information would help.

GCC is 4.3.5.

These are the data for .config and .defconfig files.

BR2_TARGET_ROOTFS_SQUASHFS=y
BR2_TARGET_ROOTFS_SQUASHFS4=y
BR2_TARGET_ROOTFS_SQUASHFS4_XZ=y
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_2_6_38=y
BR2_LINUX_KERNEL_VERSION="2.6.38.7"
BR2_LINUX_KERNEL_PATCH=""
BR2_LINUX_KERNEL_USE_CUSTOM_CONFIG=y
BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE="/usr/src/linux-2.6.38.7/.config"
BR2_LINUX_KERNEL_BZIMAGE=y
BR2_HAVE_DOT_CONFIG=y
BR2_i386=y
BR2_x86_i686=y
BR2_ARCH="i686"
BR2_ENDIAN="LITTLE"
BR2_GCC_TARGET_TUNE="i686"
BR2_GCC_TARGET_ARCH="i686"

I would like to fix the issue and submit a patch, but I am not sure how or
what to fix.  Help is very much appreciated.


Thanks!
Chris
