Compiling HISE with Faust issue (Linux)

[toxonic]

@David-Healey Nope, not yet... let me check it out

[toxonic]

@David-Healey
So, the master branch of HISE works with Faust. I opened an existing project and added a ScriptFX, and the Faust scripts work there. I can’t tell you why the master branch was able to compile — it’s a mystery to me.

What also confuses me is the fact that there apparently is no libfaust.so on my system. The symlink to the shared library libfaust.so in /usr/local/lib is, by the way, 114 MB in size… how can that be? The file cannot be traced back to an original file.

[David Healey]

@toxonic Hmm does the master branch include its own copy of faust?

[toxonic]

@David-Healey
How can I find that out? It doesn’t seem to be the case — at least no libfaust.so is included.
This is, what I get, when checking libfile.so if it's a file, and what it's linking against

It seems to link against /usr/local/lib/libfaust.so.2

And that file exists on your system?

[toxonic]

@David-Healey yep, it's in usr/local/lib

[David Healey]

@toxonic Does your symlink of libfaust.so point to libfaust.so.2?

[toxonic]

@toxonic yeah:

ls -l /usr/local/lib/libfaust.so
lrwxrwxrwx 1 root root 28 Jan 13 15:02 /usr/local/lib/libfaust.so -> /usr/local/lib/libfaust.so.2

[David Healey]

@toxonic Hmmm, what about adding a symlink here /usr/lib/x86_64-linux-gnu/libfaust.so to point to it as well?

[toxonic]

@David-Healey
Sorry, I was offline for a while! Yeah, crazy — it worked! For whatever reason, it’s compiling now!
Still the sameversion number like the master branch, is this correct?

well, cc -fuse-ld=mold -Wl,--trace -lfaust -x c /dev/null 2>&1 | grep libfaustnow outputs:

trace: /usr/lib/x86_64-linux-gnu/libfaust.so

[David Healey]

@toxonic Yes that commit hash is correct :)

[toxonic]

@David-Healey However, I still have no idea why this works now and apparently runs without any issues for all other Linux users. Is this something that should be changed in the HISE source code, or is it a problem with my system? Any idea?

[David Healey]

@toxonic I've searched the HISE source code for /usr/lib/x86_64-linux-gnu/libfaust.so and there are no hardcoded references so I think it's just that the linker expects it in that location, but I'm not entirely sure.

I guess when you install faust using make install it puts it in a different location than if you used your distro's package.

Yeah, i did that as well ... also just for libfaust and checked each occurence but found nothing!
However, thank you for youtr patience! I just would really like to know, how to avoid that in future... ;-)

Build with LLVM version 14.0.0

This LLVM version is very old BTW, I suggest using a more recent one if possible.

[toxonic]

@sletz thanks for your reply, I tried upgrading LLVM via the llvm.shfrom https://apt.llvm.org/, which seemed to work fine, but for some reason llvm-config --version still outputs 14.0.0
I checked my LLVM packages in synaptic, and I see that both versions are installed. How can I tell my system to use the most recent version on my system (20)?

[David Healey]

@toxonic You can use update alternatives. Here are instructions for gcc

@David-Healey
Ahhh, great! :-)
