VVVVVV Tech Support / Linux packaging problems, and a coredump
« on: July 27, 2011, 02:48:09 PM »
The following problems prevent usage of the bundled libraries in the Linux humble bundle version.

1) the 64-bit library directory is called LIBS64, but the VVVVV script is looking for LIB64. Solution obvious, rename it.

2) both the LIBS32 and LIBS64 library directories only include the actual libraries (e.g. libSDL-1.2.so.0.11.3) but not the sonamed symlinks by which the dynamic linker looks for them (e.g. libSDL-1.2.0). readelf -d VVVVV_* LIB*/*.so* | grep NEEDED will tell you the symlink names to use.

Unfortunately I can't then use the bundled libraries -- at least not all of them -- because libmikmod bumped soname to libmikmod.so.3 an enormously long time ago (pre-2005) when libmikmod 3.2 was released, but your code depends on libmikmod.so.2 (probably because Debian is still on libmikmod 3.1.x).

I sometimes get a coredump when using teleporters. This backtrace is using my system copy of libSDL, since yours is stripped. It's not terribly useful since VVVVVV_64 is also stripped, but for what it's worth:
