| This re-generates the file IID_to_MPH.c using gperf. |
| You need to do this after modifying either OpenSLES_IID.c or MPH.c. |
| |
| Prerequisites: |
| * GNU make |
| * GNU gperf perfect hash generator |
| $ gperf --version |
| GNU gperf 3.0.4 |
| * GNU sed |
| $ sed --version |
| GNU sed version 4.2.2 |
| |
| Usage: |
| Type 'make'. |
| Diff the old file in ../../src/autogen vs. the newly generated IID_to_MPH.c here. |
| If the differences look OK, then copy the new IID_to_MPH.c back to |
| its stable location in ../../src/autogen using 'make install'. |
| Build and test the usage of the new IID on host by "make run_test" |
| *and* on the target by tests/sandbox/engine.c. The host test |
| checks all GUIDs, and the target test checks a subset of GUIDs. |
| Then do 'make clean' or 'make distclean' here. |
| |
| hashgen is known to work on Linux with GNU gperf 3.0.4 and GNU sed |
| version 4.2.2. There are reports of problems on Mac OS X. |
