Hi,
Has anyone discovered how to cross-compile RRDtool for Freescale's P2020
using their LTIB toolchain? I am getting the familiar missing IEEE
floating-point math error:
IEEE Math Checks
checking for fpclassify... no
checking for fpclassify with <math.h>... yes
checking for isinf... yes
checking whether isfinite is broken... no
checking if IEEE math works out of the box... no

checking if IEEE math works with the -qfloat=nofold switch... no

checking if IEEE math works with the -OPT:IEEE_comparisons=ON switch... no

configure: error:
Your Compiler does not do propper IEEE math ... Please find out how to
make IEEE math work with your compiler and let me know ([email protected]).
Check config.log to see what went wrong ...
I am compiling it with the following (simplified) script:
export RFS=/local/cross-compiled/rootfs
export ARCH=powerpc
export OS=linux
export TOOLCHAIN_BASE=/opt/freescale
export
TOOLCHAIN_BIN=${TOOLCHAIN_BASE}/usr/local/gcc-4.3.74-eglibc-2.8.74-dp-2/powerpc-none-linux-gnuspe/bin
export CROSS_COMPILE=${TOOLCHAIN_BIN}/powerpc-none-linux-gnuspe-
export c=${CROSS_COMPILE}
export AS=${CROSS_COMPILE}as
export LD=${CROSS_COMPILE}ld
export CC=${CROSS_COMPILE}gcc
export AR=${CROSS_COMPILE}ar
export STRIP="${CROSS_COMPILE}strip --strip-unneeded"
export SSTRIP=${CROSS_COMPILE}sstrip
export OBJCOPY=${CROSS_COMPILE}objcopy
export OBJDUMP=${CROSS_COMPILE}objdump
export MAKE=make
export CFLAGS="-I${RFS}/usr/local/include -L${RFS}/lib"
export LDFLAGS="-I${RFS}/usr/local/include -L${RFS}/lib"
export PKG_CONFIG_LIBDIR="$( cd ${RFS}/usr/lib/pkgconfig && pwd )"
./configure --host=ppc-linux --build=i586-linux-gnu --prefix=/usr/local
Any suggestions?
Thanks!
Trevor
