@Jesus89 do you have an updated toolchain?

Jesus89 commented 6 years ago

Hi @ivankravets!

The toolchain is the same. You need to install libffi in Mac OS in order to execute yosys. The same for libftdi to enable uploading the bitstream to the FPGA.

I use brew to install these packages.

ivankravets commented 6 years ago

Do you need header files of libffi? If no, we can put libffi.6.dylib directly to that package in the folder where binary file is located. In this case, no need to install brew or libffi. What do you think?

jcw commented 6 years ago

Yep, can confirm, same issue here. Solved with brew install libffi. No headers involved, AFAICT.

abuisman commented 6 years ago

In my case linking libffi (which was already installed, but unlinked) fixed the issue

ivankravets commented 5 years ago

@jcw @abuisman could run brew uninstall libffi and run pio update? Does it work now?

hqms commented 5 years ago

In my case linking libffi (which was already installed, but unlinked) fixed the issue

or you can export variables to determine the libraries

libffi is keg-only, which means it was not symlinked into /usr/local, because some formulae require a newer version of libffi.

For compilers to find libffi you may need to set: export LDFLAGS="-L/usr/local/opt/libffi/lib"

For pkg-config to find libffi you may need to set: export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"

ivankravets commented 5 years ago

@hqms what is your macOS version? Do you use the latest version of dev/platform?

sqaview commented 5 years ago

I'm running macOS Mojave, 10.14.2 I had to uninstall libffi, then reinstall it:

brew uninstall libffi
brew install libffi

And then, set the env vars in my .bash_profile as indicated above:

# homebrew required vars
export LDFLAGS="-L/usr/local/opt/libffi/lib"
export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"

That worked 👍

tomachinz commented 5 years ago

I got it working after a re-install of libffi, without changing my env vars.

I got this message about Brew refusing to link macOS-provided software on the way but all was well...

In my case I had installed both libffi 3.2.1 and libffi 3.3, then I switched from 3.3 back to 3.2.1 like so:

brew switch libffi 3.2.1

pedrorrivero commented 4 years ago

As of today, dyld: Library not loaded: /usr/local/opt/libffi/lib/libffi.6.dylib pops up when calling ffmpeg on a fresh install of libffi.

/usr/local/opt/libffi/lib/libffi.6.dylib does not exist anymore apparrently, it has been renamed to /usr/local/opt/libffi/lib/libffi.7.dylib.

I fixed the issue by running:

cp 
/usr/local/opt/libffi/lib/libffi.7.dylib /usr/local/opt/libffi/lib/libffi.6.dylib

Notice however that when libffi is installed through hombrew (i.e. brew install libffi), it creates a symlink /usr/local/opt/libffi/lib/libffi.dylib to /usr/local/opt/libffi/lib/libffi.7.dylib. That suggests that ffmpeg should start using this alternative path instead to avoid any errors.

saleh-old commented 4 years ago

I ended up fixing it by downgrading libffi using this guide: https://dae.me/blog/2516/downgrade-any-homebrew-package-easily

freeslugs commented 4 years ago

yeah man it's just a different version libffi.6.dylib vs libffi.7.dylib

This will do the trick

cd /usr/local/opt/libffi/lib
ln -s libffi.7.dylib libffi.6.dylib

then try ffmpeg

Thank you very much indeed! Your suggestion "cp /usr/local/opt/libffi/lib/libffi.7.dylib /usr/local/opt/libffi/lib/libffi.6.dylib" solved my problem (after spending two nights trying to install why3 (before frama-c) but got stuck due to this problem. Does anybody know why not everyone has this issue? Why ....6.dylib is required by there is only a ....7.dylib? Three of us installed the same thing and the other two didn't have this issue at all

Notice however that when libffi is installed through hombrew (i.e. brew install libffi), it creates a symlink /usr/local/opt/libffi/lib/libffi.dylib to /usr/local/opt/libffi/lib/libffi.7.dylib. That suggests that ffmpeg should start using this alternative path instead to avoid any errors.

Note For M1 (Apple Silicon) Chips: The libraries are stored on different paths so linking is done by:

@dragon-yuan solution works for Monterey. In my case, I was using python 3.7 and it was requiring libffi.7.dylib. So, i created a soft link for that.

LuigiVampa92 commented 1 year ago

Faced the same issue. In my case libffi.6.dylib wasn't loading. Seems that some other library tries to load a direct version of ffilib instead of its general symlink. I only had libffi.8.dylib version:

$ cd /opt/local/lib
$ ls -la | grep libffi
-rwxr-xr-x   1 root     admin    71176 сен 24 08:34 libffi.8.dylib
-rw-r--r--   1 root     admin    42456 сен 24 08:34 libffi.a
lrwxr-xr-x   1 root     admin       14 сен 24 08:34 libffi.dylib -> libffi.8.dylib

So I had to make a copy of lib and rename in to 6, and made a 7 copy as well, just in case. After that everything was fixed and my software started working:

sudo cp /opt/local/lib/libffi.8.dylib /opt/local/lib/libffi.7.dylib
sudo cp /opt/local/lib/libffi.8.dylib /opt/local/lib/libffi.6.dylib

Hope it helps someone
