QUESTION
I create a define block
I'd like to check the program whether in the $PATH env.var,
i.e. whether program exists.
...ANSWER
Answered 2021-Jun-09 at 16:17You have several problems here:
ifneq (${exist},"")will fire the error if${exist}is not equal to"", which is the case. Tryifneq (${exist},).ls --versionsends its output to the standard output, not the standard error, so in your case, withls --version,existwill not be the empty string. It will be something likels (GNU coreutils) 8.32...- What you're doing is a strange mixture of make and shell constructs. Make recipes are shell scripts. There is no need to call the
shellmake function in a recipe. You should maybe try to write a make macro with 100% shell content (including shell variables if you need some). Do not forget to escape the make expansion if needed.
You could try something like (not tested):

QUESTION
Getting this error while building docker images on Mac OS BigSur with M1 chip.
What I've tried: Installed docker for Apple Silicon Graphic M1 from docker site
It fails while trying to install RocksDB from Docker
...ANSWER
Answered 2021-May-31 at 17:35There are a couple of issues to address. The dockerfile as you have it will download a base golang ARM image, and try to use that to build. That's fine, as long as the required libs "know how" to build with an arm architecture. If they don't know how to build under arm (as seems to be the case here), you may want to try building under an AMD image of golang.
Intel / AMD containers will run under ARM docker on an M1. There are a few ways to build AMD containers on an M1. You can use buildkit, and then:
docker buildx build --platform linux/amd64 .
or, you can add the arch to the source image by modifying the Dockerfile to include something like:

QUESTION
I have a cross-platform project which is to be built on 2 platforms: mac and linux(ubuntu).
My pipeline contains 3 jobs:
- prepare docker image with all nessesary too to build the project.
- build on ubuntu in prepared docker container, depends on step 1
- build on MacOS, needs nothing
Steps for linux and macos are definitely the same. But matrixes differs much, and linux build is run inside container.
Is there a way to share steps between two different jobs?
I tried YAML anchors but GitHub does not support them.

QUESTION
I ran across this program while writing a graphical frontend to the GNU Coreutils shred program. When a user drags in a file that has spaces in it, such as my private data.docxthe GTK+ DND service represents those spaces as %20. Using that example i would get (for the filename) my%20private&20data.docx. I need to convert those to space characters because I use the fopen function from stdio.h. fopen refuses to open filenames like that because it does not recognize %20 as a representation for a space.
ANSWER
Answered 2021-Apr-25 at 05:59No, you do not replace %20 with spaces. You decode the URL into a filename, with
g_filename_from_uri:

Answered 2021-Apr-16 at 01:29I was able to solve the issue with Kafka issue thread. As I'm not running the servers on docker also made it difficult to find a solution.
The problem was basically using a strict localhost IP address (I'm not clearly sure about this). Just by changing the strict ip server.properties in kafka/config directory.

QUESTION
I am writing a GTK+ frontend program that shreds files. The program shred from GNU Coreutils is the backend. The programming language is C.
So, I have a progress bar that show how much of the shredding is finished. But, in order to give the user accurate data on how much is shredded, the output of shred must be analyzed.
So far I have tried g_spawn_command_line_async, but I am not able to send the output of shred to a file.
ANSWER
Answered 2021-Mar-03 at 03:04The easiest solution is using unix redirection. You can call system("shred -v file_to_shred > somefile.txt") and the output will be redirect to the file. You can then read from the file using POSIX read or some other file reading method. Run the system() call in a seperate thread, and the just incremently check the file in the main thread. You could use POSIX sleep() to check the file at some interval, say, every half second. However, never use sleep on the GUI thread, as this will freeze the UI.
