Re: [Csnd-dev] Error trying to build Csound7 for Daisy

We're so used to the bison problem that we forgot all about it. It is in the BUILD.md but not in the Daisy instructions.

Sweet! I'm glad that worked. Yeah, I've been getting more and more frustrated with the way MacOS bundles up its development tools lately. It's nice that the OS is mostly still BSD- and POSIX-y, but they've made some pretty developer-unfriendly choices recently. That being said, I'm an old assembly language curmudgeon, so maybe I should get with the times, haha.

Thanks Scott, that did it! I've got libcsound.a building now. Will have to pick up the next steps in a day or two.

Much appreciated!

I had that issue as well, since I kind of hand-crafted my dev environment. It turns out there's a cmake variable you can set to point it at whatever bison path you like, so in your cmake invocation, you can do:

cmake <stuff> <stuff> -DBISON_EXECUTABLE=/full/path/to/the/bison/you/want <stuff> <stuff>

That will set all the variables in the generated makefile properly, so just running make afterwards should work.

Thanks Scott. Yes, I am running ancient Bison. I've installed a new one use brew (I'm on MacOS), but it tells me the following:

bison is keg-only, which means it was not symlinked into /opt/homebrew,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have bison first in your PATH, run:
echo 'export PATH="/opt/homebrew/opt/bison/bin:$PATH"' >> ~/.zshrc

For compilers to find bison you may need to set:
export LDFLAGS="-L/opt/homebrew/opt/bison/lib"

I don't really know cmake, wondering if anyone can tell me the incantations to get cmake's generated make to use my newer Bison?

thanks!

Hello,

What version of bison are you running? (bison --version)

On MacOS, the one that ships with XCode by default is quite old, and it gave me errors when I tried to use it as well. I manually installed the latest (at the time) version, 3.8.2, and that worked much better.

Best,

Scott

Hi devs, apologies if this is my unfamiliarity with CMake at fault. I'm trying to build the libcsound for Daisy and running into errors.

What I have done:

- clone the develop branch of csound

- followed instructions in the Daisy examples README

the cmake command runs fine. Then when I run "make", I get the errors pasted below. This looks like a code error, is there perhaps a tag or branch I need to checkout? (or something else I am doing wrong?)

thanks!
