I got a new machine (mac book m1, not sure if it matters) and I noticed I didn't have Coq:
(base) brandomiranda~ โฏ coqc -v
zsh: command not found: coqc
So I went to the instructions to download coq (https://coq.inria.fr/opam-using.html). Some part of it seems to work:
(base) brandomiranda~ โฏ opam init
eval $(opam env)
<><> Required setup - please read <><><><><><><><><><><><><><><><><><><><><> ๐ซ
In normal operation, opam only alters files within ~/.opam.
However, to best integrate with your system, some environment variables
should be set. If you allow it to, this initialisation step will update
your zsh configuration by adding the following line to ~/.zshrc:
[[ ! -r /Users/brandomiranda/.opam/opam-init/init.zsh ]] || source /Users/brandomiranda/.opam/opam-init/init.zsh > /dev/null 2> /dev/null
Otherwise, every time you want to access your opam installation, you will
need to run:
eval $(opam env)
You can always re-run this setup with 'opam init' later.
Do you want opam to modify ~/.zshrc? [N/y/f]
(default is 'no', use 'f' to choose a different file) y
A hook can be added to opam's init scripts to ensure that the shell remains in sync with the opam environment when they are loaded. Set that up? [y/N] y
User configuration:
Updating ~/.zshrc.
but then when I go get and pin coq opam can't find it:
(base) brandomiranda~ โฏ opam pin add coq 8.15.0
[ERROR] Package coq has no known version 8.15.0 in the repositories
anyone know what is going on? Seems puzzling.

synopsis Formal proof management system
description The Coq proof assistant provides a formal language to write
mathematical definitions, executable algorithms, and theorems, together
with an environment for semi-interactive development of machine-checked
proofs. Typical applications include the certification of properties of programming
languages (e.g., the CompCert compiler certification project and the
Bedrock verified low-level programming library), the formalization of
mathematics (e.g., the full formalization of the Feit-Thompson theorem
and homotopy type theory) and teaching.

=> Try to re-run the install command with PKG_CONFIG_PATH pointing a pkg-config path including libffi, e.g. if you use homebrew you can try
PKG_CONFIG_PATH=/usr/local/opt/libffi/lib/pkgconfig
The former state can be restored with:
/opt/homebrew/bin/opam switch import "/Users/brandomiranda/.opam/__coq-platform.2022.01.0~dev/.opam-switch/backup/state-20220216165905.export"
when running the coq plataform script:
(base) brandomiranda~/Downloads/platform-2022.01.0 โฏ bash coq_platform_make.sh
If you are not an opam / OCaml expert, then you're best bet to install Coq with opam is to rely on the scripts provided by the Coq Platform. See: https://github.com/coq/platform/releases
These interactive scripts will take care of:
creating a new opam switch
installing an appropriate version of the OCaml compiler
installing any external dependencies you need (e.g., if you want CoqIDE)
they can also propose to install a collection of additional Coq packages that can be useful for Coq projects
Finally, relying on this script creates a sound basis that you can later extend if you need more Coq packages that were not included in the Platform.
In case you are confsued what "install with the Coq Platform scripts" means here is a few more details:
Installing Coq
install brew: https://brew.sh/
Follow the Coq Platform scripts for installation: https://coq.inria.fr/opam-using.html or "Installation by compiling from Sources using opam" https://github.com/coq/platform/blob/main/doc/README_macOS.md.
Last time I installed this I downloaded their coq zip file with the instlal script (note check for most recent or version you want e.g. at https://github.com/coq/platform/blob/main/doc/README_macOS.md):
https://github.com/coq/platform/archive/refs/tags/2022.01.0.zip
and ran after cding to the unzipped files location of the above:
bash coq_platform_make.sh
select the version you want (likely something stable! Avoid, beta, dev. At the time of this writing option 7.
you might have to do eval $(opam env).
Check it installed correctly:
coqc -v
output something like:
The Coq Proof Assistant, version 8.16+alpha
compiled with OCaml 4.10.2
if its working
Note, for HPCs
it seems one can do this too:
# - install opam
# brew install opam
# https://stackoverflow.com/questions/72522266/how-does-one-install-opam-with-conda-for-mac-apple-os-x

I am trying to upgrade Ionic to the latest version. Looking here, it shows that the latest version is 3.0.0. I also follow this tutorial.
So I do the following:
sudo npm uninstall -g ionic
sudo npm install -g ionic#latest
console:
Richards-MacBook-Pro:theWhoZoo richardmarais$ sudo npm install -g ionic
Password:
/Users/richardmarais/npm-global/bin/ionic -> /Users/richardmarais/npm-global/lib/node_modules/ionic/bin/ionic
/Users/richardmarais/npm-global/lib
โโโ ionic#3.0.0
But when I run:
ionic -v
I get:
2.1.18
and:
ionic info
I get:
Your system information:
Cordova CLI: 6.4.0
Ionic Framework Version: 3.1.1
Ionic CLI Version: 2.1.18
Ionic App Lib Version: 2.1.9
Ionic App Scripts Version: 1.3.0
ios-deploy version: Not installed
ios-sim version: Not installed
OS: macOS Sierra
Node Version: v7.10.0
Xcode version: Xcode 8.3.2 Build version 8E2002
I would expect it to update the Ionic CLI Version: 2.1.18 to 3.0.0. Is that a correct assumption? If so, do you know what I am doing incorrectly?
Thanks
We did big chat. Things which were helpful:
Be sure that you completely delete all previous version with npm uninstall -g ionic or manually from rm -rf /usr/local/lib/node_modules. Don't forget remove symlink too: rm -rf /usr/local/bin/ionic
After completely deletion you should see error: command not found of ionic -v
And now if your npm root -g path is right like /usr/local/lib/node_modules try to install npm install -g ionic#latest. Then you should get correct output of ionic -v
The ionic CLI package has been renamed #ionic/cli
https://twitter.com/ionicframework/status/1223268498362851330
So you should uninstall ionic from your global
npm uninstall -g ionic
and add the new package name.
npm install -g #ionic/cli#latest
In case anyone comes here from google.
I simple run
$ ionic --version
$ 4.2.1
$ sudo npm i -g ionic#latest
$ ionic --version
$ 4.8.0
I would start trying the simple things before.
I just ran...
npm --version
Then, the answer was...
4.6.0

I am following a coq tutorial, which requires a basic coq OPAM library coq:io:system. But I got errors with OPAM. (This is with Ubuntu14.04, coq 8.4pl6 and opam1.2.1)
I googled around and didn't find any solution.
Does anyone know what the problem might be and how to fix this error?
Thanks.

It turns out that (as the error message suggests), this particular package seems to depend on ruby.
I was able to finish the installation after installing ruby with sudo apt-get install ruby.
When using coffee-script this command runs ok on 1 computer but silently fails on another.
coffee --output dir --compile dir
make: *** [js] Error 1
How can I debug? Any flags for verbose output?
npm list -g
/usr/local/lib
โโโฌ coffee-script#1.7.1
โ โโโ mkdirp#0.3.5
โโโ csso#1.2.15
โโโ uglify-js#1.3.2
Even coffee --version fails with no output
It was a terrible mix of old Ubuntu's/new packages.
Needed to remove node, nodejs packages.
Install new versions from PPA
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install python-software-properties python g++ make nodejs
Reinstall coffee-script: sudo npm install coffee-script -g
Thanks
My question is specific to the library libMPSSE from FTDI to work with USB to serial port (SPI, I2C, etc) adapters on Linux.
When I execute any program linked with the library, the method Init_libMPSSE() is called (without explicit invocation) and throws the following message.
../../Infra/src/ftdi_infra.c:243:Init_libMPSSE(): NULL expression encountered
Has anybody experienced this issue and found a workaround?.
Thanks.
You get this error when libMPSSE can't open the libftd2xx.so shared library. You need to set LD_LIBRARY_PATH to the path where this library was installed. For example if the library is in /usr/local/lib you would run the SPI static example like this:
sudo LD_LIBRARY_PATH=/usr/local/lib ./sample-static.o
A:
Using:
sudo LD_LIBRARY_PATH=/usr/local/lib ./your_application
is only one of the important steps!
Important: not using sudo can result in a failure like described here!
B:
But on Linux make sure that before you execute the command above, you disable the FTDI's VCP drivers that are already included in the Linux kernel. VCP drivers and libftd2xx drivers cant coexist! So, even before you execute the command above, you have to (a) plug in the device and (b) dissable the VCP drivers:
โโโโโ
โ $ โ ziga > ziga--workstation > Downloads
โโโฌโโ /dev/pts/3
โโ> sudo rmmod ftdi_sio
โโโโโ
โ $ โ ziga > ziga--workstation > Downloads
โโโฌโโ /dev/pts/3
โโ> sudo rmmod usbserial
Now, your application will be able to talk with libftd2xx drivers because VCP drivers will not interfere. So now you can execute the command in A:.
C:
Pay attention that bitness of the libMPSSE (& therefore your application) and libftd2xx have to also be the same! 32-bit or 64 bit!
For Linux, FTDI only provides 32-bit precompiled libMPSSE library here, but they provide 32-bit and 64-bit libftd2xx drivers here. So if you installed 64-bit libftd2xx, you need to compile the 64-bit libMPSSE library yourself! Sources are available here.
If we are on 64-bit system, we download the sources and we will get the compressed file libMPSSE_Source.zip. We extract it:
โโโโโ
โ $ โ ziga > ziga--workstation > Downloads
โโโฌโโ /dev/pts/4
โโ> unzip libMPSSE_Source.zip
and we will get a folder libMPSSE__0-6_Source. We move inside and try to build the library!
โโโโโ
โ $ โ ziga > ziga--workstation > Downloads
โโโฌโโ /dev/pts/4
โโ> cd ./libMPSSE__0-6_Source/LibMPSSE/
โโโโโ
โ $ โ ziga > ziga--workstation > LibMPSSE
โโโฌโโ /dev/pts/4
โโ> cp ../External/Linux/libftd2xx1.1.12/release/ftd2xx.h .
โโโโโ
โ $ โ ziga > ziga--workstation > LibMPSSE
โโโฌโโ /dev/pts/4
โโ> cp ../External/Linux/libftd2xx1.1.12/release/WinTypes.h .
โโโโโ
โ $ โ ziga > ziga--workstation > LibMPSSE
โโโฌโโ /dev/pts/4
โโ> gcc -Wall -c *.c
ftdi_mid.c: In function โMid_CheckMPSSEAvailableโ:
ftdi_mid.c:653:2: error: unknown type name โbyteโ
653 | byte los = strlen(devList.Description);
| ^~~~
We will see that there is an error but it is fixable. We just open a file ftdi_mid.h and move to the line 653 which we edit like this:
unsigned char los = strlen(devList.Description);
Now we compile .h files to .o files and create an archive i.e. static library libMPSSE.a:
โโโโโ
โ $ โ ziga > ziga--workstation > LibMPSSE
โโโฌโโ /dev/pts/4
โโ> gcc -Wall -c *.c
โโโโโ
โ $ โ ziga > ziga--workstation > LibMPSSE
โโโฌโโ /dev/pts/4
โโ> ar -cvq libMPSSE.a *.o
a - ftdi_common.o
a - ftdi_i2c.o
a - ftdi_infra.o
a - ftdi_mid.o
a - ftdi_spi.o
We can now also move this 64-bit library in our project's folder and we can use this one, but doing this would demand us to remove or rename the 32-bit libraries that are already there.
D:
To compile my application with 32-bit libraries, I used:
gcc -Wall -Wpedantic -g -gdwarf-2 -m32 -L. -o main.elf main.c -lMPSSE -ldl
Note that I am on Debian 11 and in order to crosscompile with -m32 flag, you need to install the package gcc-multiarch.
But to compile my application with 64-bit libraries, I used:
gcc -Wall -Wpedantic -g -gdwarf-2 -L. -o main.elf main.c -lMPSSE -ldl
