buildgdi -rebuild flattens file system tree

[lhsazevedo]

When running buildgdi in rebuild mode on Linux, the directory hierarchy from the source is not preserved. Instead, all files are placed at the root of the disc with path components joined into filenames.

$ buildgdi          
BuildGDI v2.1.1 - Command line GDIBuilder
(...)

$ list-gd-files original/track3.bin
├── 0GDTEX.PVR
├── 1ST_READ.BIN
├── OD_COMMON/
│   ├── 3S_2DO0_L.NJD
│   ├── 3S_2DO0_S.NJD
│   ├── 3S_2DO0_SN.NJD
(...)

$ ls rebuild_root
1ST_READ.BIN

$ buildgdi -rebuild -gdi original/original.gdi -data ./rebuild_root/ -output ./rebuild_out/
Writing......... Done!

$ list-gd-files rebuild_out/track03.bin
├── 0GDTEX.PVR
├── 1ST_READ.BIN
├── OD_COMMON/
├── OD_COMMON_3S_2DO0_L.NJD

Note: list-gd-files is a small script I wrote to debug the GD file system. It’s not part of GDIBuilder and hasn’t been released yet.

Context:

GDIBuilder version: v2.1.1
OS (host): Linux Mint 21.3
OS (container): Debian 12
