Hi,
I am having some trouble while cross compiling EPICS Base for linux-arm
on my linux-x86_64 machine and my cross toolchain from Openembedded.
Build crashes at :
*************
...

***********
My configurations:
Under configure dir I set in CONFIG_SITE file:
CROSS_COMPILER_TARGET_ARCHS=linux-arm
CROSS_COMPILER_HOST_ARCHS=linux-x86_64
Under configure/os I copied CONFIG_SITE.linux-x86.linux-arm to
CONFIG_SITE.linux-x86_64.linux-arm
and set there:
GNU_TARGET = arm-angstrom-linux-gnueabi
GNU_DIR =
/opt/oecore-x86_64/sysroots/x86_64-angstromsdk-linux/usr/bin/arm-angstrom-linux-gnueabi
as this is the folder containing toolchain binaries as
arm-angstrom-linux-gnueabi-gcc and so on.
Additionally I had to make a soft-link "bin" inside this directory
pointing to this directory for EPICS to find the binaries.
The missing stdio.h is under
/opt/oecore-x86_64/sysroots/armv7at2hf-vfp-neon-angstrom-linux-gnueabi/usr/include
.
Hopefully someone could help.
Thanks
