ESP8266 via ArduinoIDE on Mac OSX issue - arduino

I have recently switch to Macbook and got some troubles with ESP8266 programming via ArduinoIDE. As far as I know my USB-TTL converter is basen on PL2303 series. I have already tried this solution:
http://hpclab.blogspot.com/2015/06/esp8266-arduino-ide-on-mac-os-x.html
But I have just downloaded files and went with sudo python setup.py install so I got my files in /usr/local/bin. Then I changed the platform.txt as written at blog and as result I got:

I would be really glad if anyone of you could help me with that.
Best regards.

Freebasic install for Raspberry Pi problem

I am looking to install Freebasic on a Raspberry Pi. I have already looked at the Freebasic forum - but it seems from a lot of posts that others have found that following the steps shown no longer end up working.
Other Pi forums have said that a working installation can be difficult to achieve.
I am trying to find a way to get the freebasic compiler running on an otherwise virgin installation, starting from Noobs.
At first I thought it was too difficult for me, but even some serious pi-enthusiasts who were going to help me have ended up stumped.
This link has a step by step that can be considered simple, as long as attention is paid to the directories and first step, installing some necessary packages.
I followed steps 1 through 5 and installed it on my Raspberry.
From what is reported there, "part of the problem is that FreeBASIC is written primarily in FreeBASIC, so you need a working compiler to initialize the latest version".
Therefore, you need to install an "old version" (step #2), clone the latest version and compile it with the old version (step #3). Uninstall old version (step #4) and install new version (step #5).
In step #3 I used the make -j4 command. I have a Raspberry Pi 3 model B.
In my case, I used fbc_linux_armv6_rpi_0365_2020-01-12.zip as "old version". I tested the installation by compiling and running a program and it was OK, working perfectly.

Error while loading the Code Generator toolbox in Scilab

I installed Scilab 5.5.2 on Windows 10, and then installed the Scilab Code Generator toolbox.
However, when I start Scilab, the following message appears and I can't use the toolbox. This problem occurs for every toolbox.
Start Scilab Code Generator
Version: 0.9.20190122
Load macros
atomsLoad: An error occurred while loading 'xcos_code_generator-0.9.20190122':
File "C:\Users\光\AppData\Roaming\Scilab\SCILAB~1.2\atoms\x64\XCOS_C~1\09E129~1.201\macros\names" does not exist or read access denied.
(光 is my username.)
I suppose the problem comes from "\Scilab\SCILAB~1.2" in the middle of the file path. In my computer, the only folder in "Scilab" is "scilab-5.5.2", so indeed the software cannot find the file it's looking for.
Does anyone have any ideas?
I need to use the toolbox at work soon, so any help is greatly appreciated. Thank you in advance.
Note: I'm not using the latest Scilab 6.0.2 because it fails to work on my computer. It closes immediately after I open it.
I solved the problem by myself.
It was my user name "光" that caused the problem. I found people saying that user names in full-width characters such as Japanese sometimes cause problems like this.
The solution is to create another user account with a name in half-width characters and install Scilab in that account. (Just changing the full-width user name doesn't work because it doesn't change the filenames that already exist.)
I couldn't find the solution until today because I was searching for solutions only in the context of Scilab, not in the context of software in general.
I hope this answer helps someone.
I'm not sure why you are using an outdated version of Scilab. The latest version is 6.0.2 on Windows. If the newer version doesn't work properly then that's the problem you need to fix first. To test your Scilab installation you may run it in the terminal. Find the installation folder. For me, it is C:\Program Files\scilab-6.0.2\bin the on cmd go to the path and run Scilex.exe. If not uninstall everything and install it in a proper way. My recommendation is to uninstall the old Scilab you already have. Then:
Install Chocolatey package manager
Open PowerShell as Admin and run choco update all -y, once in a while update your packages this way.
run choco install Scilab -y
then open the Scilab software
run the atomsInstall("xcos_code_generator") in the console
runt the atomsLoad("xcos_code_generator") to make sure your package is installed properly. You should see this as a result:
--> atomsInstall("xcos_code_generator")
Scanning repository http://atoms.scilab.org/6.0 ... Done
ans =
!xcos_code_generator 0.9.201901 user SCIHOME\atoms\x64\xcos_code_generator\0.9.201901 I !
--> atomsLoad("xcos_code_generator");
Start Scilab Code Generator

Arduino IDE crashes without any warning

I'm a beginner in arduino. I just installed Arudino IDE (arduino-1.0.5-r2-windows) but when I try to run its not responding and crashes after few minutes.
I tried re-installing it and removing the temporary files but none of those helped.
Can anyone tell me what causes this problem and how to debug it?
Installing Arduino 1.5.6 solved the issue.

Error -1001 in clGetPlatformIDs Call !

I am trying to start working with OpenCL. I have two NVidia graphics card, I installed "developer driver" as well as SDK from NVidia website. I compiled the demos but when I run
./oclDeviceQuery
I see:
OpenCL SW Info:
Error -1001 in clGetPlatformIDs Call
!!!
How can I fix it? Does it mean my nvidia cards cannot be detected? I am running Ubuntu 10.10 and X server works properly with nvidia driver.
I am pretty sure the problem is not related to file permissions as it doesn't work with sudo either.
In my case I have solved it by installing nvidia-modprobe package available in ubuntu (utopic/multiverse). And the driver itself (v346) was installed from https://launchpad.net/~mamarley/+archive/ubuntu/nvidia
Concretely, I have installed nvidia-opencl-icd-346, nvidia-libopencl1-346, nvidia-346-uvm, nvidia-346 and libcuda1-346. Not sure if they are all needed for OpenCL.
This is a result of not installing the ICD portion of Nvidia's openCL runtime. The ICD profile will instruct your application of the different openCL implementations installed on the system as multiple implementations from different vendors can coexist. Whe your application does not find the ICD information it gives the Error -1001.
Run your program as root. In case of success: you have trouble with cl_khr_icd- extension to load the vendor driver.
If you not running X11, you have to create device files manually or by (boot-)script:
ERROR: clGetPlatformIDs -1001 when running OpenCL code (Linux)
Same problem for me on a Linux system. Solution is to add the user to the video group:
# sudo usermod -aG video your-user-name
Since I just spend a couple of hours on this, I thought I would share:
I got the error because I was connected to the machine per remote desktop (mstsc). On the machine itself everything worked fine.
I have been told that it should work with TeamViewer by the way.
Dont know if you ever solved this problem, but I had the same issue and solved it in this post: ERROR: clGetPlatformIDs -1001 when running OpenCL code (Linux)
Hope it helps!
I have solved it in Ubuntu 13.10 saucy for intel opencl by created link:
sudo ln -s /opt/intel/opencl-1.2-3.2.1.16712/etc/intel64.icd /etc/OpenCL/vendors/nvidia.icd
I just ran into this problem on ubuntu 14.04 and I could not find ANY working answers anywhere online including this thread (though this was the first to show up on google). What ended up working for me was to remove ALL previous nvidia software and then to reinstall it using the .run file provided on the nvidia website. Installing the components through apt-get seems to fail for some reason.
1) Download CUDA .run file: https://developer.nvidia.com/cuda-downloads
2) Purge all previous nvidia packages
sudo apt-get purge nvidia-*
3) Install all run file components (you will likely have to stop X or restart in recovery mode to run this)
sudo sh cuda_X.X.XX_linux.run
This is because OpenCL has the same brain damaged one library per vendor setup that OpenGL has. A likely reason for the -1001 error is that you have compiled with a different library than the linker is trying to dynamically load.
So see if this is the problem run:
$ ldd oclDeviceQuery
...
libOpenCL.so.1 => important path here (0x00007fe2c17fb000)
...
Does the path point towards the NVidia-provided libOpenCL.so.1 file? If it doesn't, you should recompile the program with an -L parameter pointing towards the directory containing NVidia's libOpenCL.so.1. If you can't do that, you can override the linker's path like this:
$ LD_LIBRARY_PATH=/path/to/nvidias/lib ./oclDeviceQuery
For me, I was missing the CUDA OpenCL library, Running sudo apt install cuda-opencl-dev-12-0 solved it.
You should get number of platforms, allocate the memory for platforms, again get this platforms and then create context from this platform. There is good example:
http://developer.amd.com/support/KnowledgeBase/Lists/KnowledgeBase/DispForm.aspx?ID=71
This might be due to querying clGetPlatformIDs by multiple threads at the same time

How do I use the bootstrap and configure commands in Ubuntu?

I am trying to solve a problem getting QDevelop to build code given to me from another workstation and I am getting all kinds of errors which I posted a question about but havn't received any responses. See: QDevelop Qt IDE in Ubuntu 10.04 LTS Lucid Lynx qwt
I found someone having the same problem and I don't understand their solution. See: http://www.ruby-forum.com/topic/202124
Greetings,
I removed libqwt-dev and did a .bootstrap and .configure and make and
all is now well.
Rob
My question is how do I use the .bootstrap command (./bootstrap)? And what the heck does it do for that matter? I can't find anything when I Google it.
While I am at it what does .configure (./configure?) do and how do I use it also?
I am running Ubuntu 10.04 Lucid Lynx
Thanks,
DemiSheep
I switched to another IDE and OS's. :)
