Experimental Physics and
Industrial Control System

Hello all,

I am trying to cross-compile EPICS base-7.0.8 for a target architecture of linux-arm (Zynq-7000 board), with my host being linux-x86_64. 

I have modified the configure/CONFIG_SITE file to set CROSS_COMPILER_TARGET_ARCHS=linux-arm, 

and I have set the GNU cross-compiler target name and the GNU tools install path in the file configure/os/CONFIG_SITE.linux-x86.linux-arm as follows:

GNU_TARGET = arm-linux-gnueabihf

GNU_DIR = /opt/petalinux/2018.3/tools/linux-i386/gcc-arm-linux-gnueabi

I have verified that the GNU tools path is correct:

$ ll /opt/petalinux/2018.3/tools/linux-i386/gcc-arm-linux-gnueabi/bin

total 51M

However, when I run make for base-7.0.8, I encounter the following errors:

It seems that "make" is trying to use /usr/bin/arm-linux-gnueabihf-gcc instead of the specified path. I have verified that the cross-compiler is correctly installed and available in the specified directory.

I have also tested the same cross-compilation setup with base-7.0.6.1 and base-7.0.7, and both versions compile successfully.

Do you have any suggestions?

Thank you!
