Issue ID: 127040
Issue Type: DEFECT
Summary: Patch for arm 32
Product: Build Tools
Version: 4.2.0-dev
Hardware: Other
OS: Linux 32-bit
Status: CONFIRMED
Severity: Normal
Priority: P5 (lowest)
Component: configure
Assignee: [email protected]
Reporter: [email protected]
It was not possible to build on Linux ARM (32 bits) with the trunk version of
Aoo, while it does perfectly build with OOo4Kids and OOoLight.
So, I propose a patch, using the same changes I did on ARM for OOo4Kids and
OOoLight a while ago, and perfectly building and working on recent armv7+
boards.
The attached patch, under Apache License, is a proposal (feel free to improve
it) to allow building AOo on :
- old fashion ARMV4T on old machines (was before the patch) ;
- softfp abi on ARMV6 ;
- hardfloat abi arm isa v7+ architectures.
IMPORTANT : after the patch being applied,and before configure, you MUST run
"autoconf" in the main directory, to apply and keep the proposed changes.
Modified files :
- solenv/inc/unxlngr.mk : added ARM_FLAVOUR, ARMV7 macros, improved ARM_TARGET
with better flags ;
- sal/osl/unx/intelck.c : added smp barriers (arm processors are multi-cores
since a while) ;
- configure_ac : added new cases, ARMV7 is now the default (doesn't make sense
to build OOo for previous architectures, but who knows ... ) ;
- set_soenv.in : added ARM_FLAVOUR macro ;
- modified EPM_FLAGS (needed when building the .debs) ;
- added OUTPATH : unxlngrh for hardfloat abi when available.
How to use it :
at configure time, add :
--with-arm-target=7 (or 5, or 6 ... ) => will define ARMV7 macro
And in the case the libc is fpuv3 comptabile, the hardfloat abi will be used,
(else it will be the softfp).
Notes:
- this patch has just been partially tested with AOO build
- it has not been tested on armv8 (64 bits)
- default value is armv7+ isa ;
- the flags need to be checked after configure.
Tested on Raspberry Pi 3 rev. B
