I use file:consult function to read data from config file of my application. But some times i got error: {badmatch,{error,system_limit}} How can i avoid this?
I read about ERL_MAX_PORTS, but i haven't this variable:
echo $ERL_MAX_PORTS
i got empty string. How i can correctly set ERL_MAX_PORTS or can i find other methods to avoid this error?
Thank you

After booting SWUpdate yocto-generated image for the first time, executing swupdate results in error message:
Error parsing configuration file: 'globals' section missing, exiting.
I tried to strictly follow SWUpdate's documentation, but it gets short when it comes to yocto integration. I'm using meta-swupdate, meta-swupdate-boards, and meta-openembedded layers together with poky example repository all at Kirkstone tag, building via bitbake update-image and having modyfied local.conf as:
MACHINE ??= "raspberrypi4-64"
ENABLE_UART = "1"
RPI_USE_U_BOOT = "1"
IMAGE_FSTYPES = "wic ext4.gz"
PREFERRED_PROVIDER_u-boot-fw-utils = "libubootenv"
IMAGE_INSTALL:append = " swupdate"
Is there anything else I need to modify to generate the configuration file and be able to run SWUpdate binary properly?
Side question: In the documentation, it's recommended to append swupdate-www to achieve a better web server. However, if I append it, there is no swupdate-www binary inside the `/usr/bin' directory.
As with other recipes folders the recipes-support/swupdate/swupdate/raspberrypi4-64 folder was missing inside the meta-swupdate-boards layer. Therefore, an empty config file was always generated. After adding this folder and all related files, strongly inspired by raspberrypi3 folder, the error was gone and swupdate -h provided the expected output.
There was also one new error during build process thrown by yocto. It was related to missing systemd requirement and was solved by adding:
DISTRO_FEATURES_append = " systemd"
to local.conf
When I run the ioslate.c file I get the error:
unable to read .replit:

help?
I working on a version bump on the cc65 and encountered a problem with the linuxdoc-tools. Since I can't fix the linuxdoc-tools and there is a simple workaround possible I decided to add an if statement to inform the user together with the workaround:
if {! [file exists ${prefix}/bin/perl] } {
ui_error "
«${prefix}/bin/perl» is missing but the linuxdoc-tools depends on it.
Please create an appropriate symbolic link for linuxdoc-tools to work.
"
exit 1
}
Crude but the best I can do since I'm neither the perl5 nor the linuxdoc-tools maintainer and I don't want to spend to much time on a version bump.
However, the MacPorts doesn't understand exit 1 and ui_error won't stop execution on its own.
How do I stop the execution so not to waste the users time on a build which will otherwise fail right at the end.
Use return -code error "error message", or the shorthand for the same thing, error "error message".
Note that you should use ui_error before that to print a human-readable message for the user – while the error message is also being printed, it can sometimes get lost in the output.
Additionally, note that $prefix/bin/perl is a build dependency of linuxdoc-tools. If it is also needed at runtime, you should submit a pull request that adds depends_run path:bin/perl:perl5 to the port rather than attempting to fix this bug in your port.
We are analyzing sequencing data while filtering and trimming fastq files encountered following error. Is the following error due to unavailability of core for processing commands?
Error in colnames<-(*tmp*, value = c("cs103_R1_dada.fastq", "cs110_R1_dada.fastq", : attempt to set 'colnames' on an object with less than two dimensions In addition: Warning message: In mclapply(seq_len(n), do_one, mc.preschedule = mc.preschedule, : all scheduled cores encountered errors in user code >
As pengchy suggested there may be something wrong with function.
try the same call by using lapply and error message will be more informative.
To clarify on what #f2003596 and #HelloWorld said: This just means that a crash occurred within the function you called, i.e. while it was executing that function. But this does not necessarily mean that your function is incorrect. For example, you get the same error when a variable has not been found.
That would mean your R function has a crash.
Note: If you include an unexpected argument in mclapply you also can get this error message. I put mC.cores instead of mc.cores by mistake and I got it.
I need to open my system monitor in the QTCreator, but when I try to do it I obtain the following error message:
/home/arakul/sysmon.sgrd: 2: /home/arakul/sysmon.sgrd: Syntax error: newline unexpected
I am trying to open the system monitor by using the following command:
execlp("/home/arakul/sysmon.sgrd","",NULL);
Sorry for my stupid question. I must use command ksysguard with parametrs.
system("ksysguard --desktopfile sysmon.sgrd");
