Chrome + NaCl + libmodplug + ... = tracker modules on the web

Some notes I took while looking into how to build a libmikmod_x86_32.nexe and libmikmod_x86_64.nexe to get Chrome tracker module playing support from javascript (the work seems to be done already in naclports) via NativeClient, for all the MOD, S3M, XM, IT, 669, AMF, AMS, DBM, DMF, DSM, FAR, MDL, MED, MTM, OKT, PTM, STM, ULT, UMX, MT2 and PSM formats:

• In a Chrome 11 profile, go to about:flags, and click Enable under "Native Client", and then the "Relaunch Now" button at the bottom (alternatively: start the session with the --enable-nacl command-line flag)
• Download the NaCl SDK (for Chrome 11, in my case; eventually the ABI will supposedly freeze and cover a wider range of versions)
• Download depot_tools, extract it and export NACL_SDK_ROOT=$PWD in that directory (technical overview here)
• Check out naclports
• Probably optional: comment out all the RunInstallScript lines in naclports/src/packages/nacl-install-all-bitsize.sh except the one you're interested in (in my case: RunInstallScript libmodplug-0.8.7 nacl-libmodplug-0.8.7.sh)
• Run nacl-install-all-bitsize.sh 64 (or 32 for a 32-bit build), which, in my case, built $NACL_SDK_ROOT/toolchain/mac_x86/nacl64/usr/lib/libmodplug.a
• About here my research petered out, as I found this smaller hack for XM-only playback by some forthcoming Japanese fellow (git repository here; English translation of same page c/o Google Translate), which has basic functionality
• If you got curious about my original venue and proceeded further, I'd love to hear about it, especially if you managed to build the final nexe:s; do post a comment!
