Build fails: Failed to init MIME DB

[humdinger]

This is hrev55664, 64bit Haiku source is at hrev55667.

Buildtools are up-to-date. My "generated" folder sits on a separate volume and is linked to the "haiku" top folder. I've removed generated/objects.

I successfully configured from within the "generated" folder with:

/HaikuSrc/haiku/configure -j8 --distro-compatibility official --target-arch x86_64 --cross-tools-source /HaikuSrc/buildtools --build-cross-tools x86_64

jam -qj1 DiskProbe fails with:

Please run the command with strace. That is:

generated/objects/haiku_host/x86_64/release/tools/mimeset -f --mimedb "generated/objects/common/data/mime_db/mime_db" "generated/objects/haiku/x86_64/release/system/libroot/libroot.so"

and attach the output here.

My "generated" folder sits on a separate volume and is linked to the "haiku" top folder. I've removed generated/objects.

Ah, I missed this detail last time, this is probably the cause. For now, try sym-linking the "generated" directory to the other volume from within the "haiku" checkout, and see if that works for now.

Some parts of the build system may assume everything happens on the same volume, though. (When did this stop working?)

Replying to waddlesplash:

I don't think I quite understand... Isn't that what I already had? I've now put all generated folders in a subfolder on the "Generator" volume (before those were directly in the root folder of the volume).

/HaikuSrc/haiku> ls -la
lrwxrwxrwx 1 user root    20 Jan 28 09:29 generated -> /Generator/generated

In any case, still does not work. Attached is the strace output you suggested above.

I've been getting that error for a few months now.
I guess I'll be moving the source to the "Generator" volume and try doing all on the same volume. 10 GiB free space should do, I guess.

FWIW, moving the source to the "Generator" volume and building it all on that one volume works.
