# build_unified_bridge.sh — Compile ix_unified_bridge.so on BI-V100 real hardware
|
||
|
|
#
|
||
|
|
# This builds a single .so that exposes all 14 ixformer::infer functions
|
||
|
|
# to Python via pybind11. It links against the base image's existing
|
||
|
|
# ixformer .so files at runtime (no static linking needed).
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# cd /tmp/gdn_test/project_6 && bash ex_engine/build_unified_bridge.sh
|
||
|
|
#
|
||
|
|
# Output:
|
||
|
|
# ex_engine/build/ix_unified_bridge.cpython-310-x86_64-linux-gnu.so
