The ARMV7 build target builds for the ARMV7 architecture that supports Thumb-2 instruction set. For details on ARMV7 architecture, refer to http://www.arm.com/products/CPUs/architecture.html. To build for ARMV7, ARM's RealView Compilation Tools (RVCT) v3.1 or later is required.
To build binaries for ARMV7 with abld, use:
abld build ARMV7 [udeb | urel]
Binaries are generated in the udeb and urel sub-directories of the epoc32\release\ARMV7\ directory for ABI v2.
Note: Code is not built for ARMV7 target by default. It has to be explicitly specified on the command line or in the BLD.INF file using the prj_platforms statement.
