Re: cross-compiling v7.0.7

[Simon Rose via Tech-talk <tech-talk at aps.anl.gov>]

We also at ESS use multiple cross-compiler target archs, and we also set INSTALL_LOCATION with no issue.

 

I’ve tried poking around with setting or unsetting EPICS_BASE and TOP as environment variables and I cannot reproduce the issue either, for what it’s worth.

Actually that suggestion was about using multiple CROSS_COMPILER_HOST_ARCHS (not TARGET_ARCHS, we build for multiple cross-targets here with no problems), but Pierrick doesn't seem to be doing that. Setting INSTALL_LOCATION might have something to do with if that was done, although I think I tested that.

Hi Mark,
I do actually have these definitions:

CROSS_COMPILER_TARGET_ARCHS=linux-arm_raspberrypi2
linux-arm_raspberrypi3 linux-arm_raspberrypi4 linux-arm_terasicsoc
linux-arm_achilles linux-x86_64cross linux-x86_i486 linux-ppc_mvme8100

and

CROSS_COMPILER_HOST_ARCHS=linux-x86_64

As mentioned before, if I have CROSS_COMPILER_TARGET_ARCHS empty, then
there is no problem building for the host.
Thank you,
Pierrick
