I am trying to read values from ".ini" file using install script Custom Action which will be installed at the target location. Below Install-script Code line doesn't read any values even the file is there at target location during installation.
Install Script Code :
GetProfString(TARGETDIR + "SampleSetup.ini","Main","AppTitle",szItemName);
Custom Action : Below is the major custom Action detail which was scheduled to be run "After InstallFinalize".
Function Name : AddDesktopShortCut (Custom Install Script Function)
Target : Synchonous(Check Exit Code)
In-Script Execution : Immediate Execution
Execution Scheduling : Always execute
Install UI Sequence :
Install Exec Sequence : After IntallFinalize
Install Exec Condition : Not Installed
Remaining Settings are the default ones.
Any help will be highly appreciated. Thanks for your Time.
If that's all of your code, how can you tell if it read the value?
I would suggest either using the debugger, or sprinkling some MessageBox calls in to see what values your program uses. In particular, ensure the ini file is where your code is looking (TARGETDIR + "SampleSetup.ini" should likely be TARGETDIR ^ "SampleSetup.ini" instead), check the return code from GetProfString, and see what szItemName is after the call.

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
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 $prefix/bin/perl is a build dependency of linuxdoc-tools. If it is also needed at runtime, you should submit a pull request that adds depends_run path:bin/perl:perl5 to the port rather than attempting to fix this bug in your port.
Running chef-solo (Installing Chef Omnibus (12.3)) on centos6.6
My recipe has the following simple code:
package 'cloud-init' do
action :install
end
log 'rpm-qi' do
message `rpm -qi cloud-init`
level :warn
end
log 'yum list' do
message `yum list cloud-init`
level :warn
end
But it outputs the following:
- install version 0.7.5-10.el6.centos.2 of package cloud-init
* log[rpm-qi] action write[2015-07-16T16:46:35+00:00] WARN: package cloud-init is not installed
[2015-07-16T16:46:35+00:00] WARN: Loaded plugins: fastestmirror, presto
Available Packages
cloud-init.x86_64 0.7.5-10.el6.centos.2 extras
I am at a loss as to why rpm/yum and actually rpmquery don't see the package as installed.
EDIT: To clarify I am specifically looking for the following string post package install to then apply a change to the file (I understand this is not a very chef way to do something I am happy to accept suggestions):
rpmquery -l cloud-init | grep 'distros/__init__.py$'
I have found that by using the following:
install_report = shell_out('yum install -y cloud-init').stdout
cloudinit_source = shell_out("rpmquery -l cloud-init | grep 'distros/__init__.py$'").stdout
I can then get the file I am looking for and perform
Chef::Util::FileEdit.new(cloudinit_source.chomp(''))
The file moves based on the distribution but I need to edit that file specifically with in place changes.
Untested code, just to give the idea:
package 'cloud-init' do
action :install
notifies :run,"ruby_block[update_cloud_init]"
end
ruby_block 'update_cloud_init' do
block do
cloudinit_source = shell_out("rpmquery -l cloud-init | grep 'distros/__init__.py$'").stdout
rc = Chef::Util::FileEdit.new(cloudinit_source.chomp(''))
rc.search_file_replace_line(/^what to find$/,
"replacement datas for the line")
rc.write_file
end
end

I would better go using a template to manage the whole file, what I don't understand is why you don't know where it will be at first...
Previous answer
I assume it's a compile vs converge problem. at the time the message is stored (and so your command is executed) the package is not already installed.
Chef run in two phase, compile then converge.
At compile time it build a collection of resources and at converge time it execute code for the resource to get them in the described state.
When your log resource is compiled, the ugly back-ticks are evaluated, at this time there's a package resource in the collection but the resource has not been executed, so the output is correct.
I don't understand what you want to achieve with those log resources at all.
If you want to test your node state after chef-run use a handler maybe calling ServerSpec as in Test-Kitchen.
I am trying to run ADNI .mnc image in MATLAB
I added folder emma-master, niak-0.7.1-ammo, mia and niak-0.7.1-ammo to my path. All these folders are located in
D:\EMINA BURCH\PhD Thesis\MATLAB Packages
But when I want to open ._bq_t_15T.mnc located also in D:\EMINA BURCH\PhD Thesis\MATLAB Packages
that is h = openimage('._bq_n_15T.mnc')
I get the following error
Error using miinquire (line 145)
Error getting image dimensions from file D:\EMINA BURCH\PhD Thesis\MATLAB Packages._bq_n_15T.mnc
Error in openimage (line 173)
DimSizes = miinquire (filename, 'imagesize');
When I enter debug mode in minquire function after the line
[stat,out] = system(['mincinfo -vardims image ' minc_file]);
I get stat = 1 and out = 'mincinfo' is not recognized as an internal or external command, operable program or batch file.
May You, please help me with this issue.
system isn't able to automatically recognise the different requirements that might be needed to run the same system command on different operating systems. Using commands like ispc, isunix, ismac and computer, you can automatically check and call different versions of the commands as appropriate:
if ispc
[stat,out] = system(['mincinfo.exe -vardims image ' minc_file]);
else
[stat,out] = system(['mincinfo -vardims image ' minc_file]);
end
Of course, you also have to have the appropriate program on your MATLAB path for this to work.
I have a .c file compiled and would like to run via a cron job but I end up getting this error:
/bin/sh: /usr/local/bin/get1Receive.c: Permission denied.
What is causing this error and how do I fix it?
Should I be running the .c file in cron or a different compiled file?

If the output of this command:
file get1Receive1.c
shows that file name to be a valid executable that part is very unusual, but okay.
Assuming you are using biz14 (or your real username's ) crontab try this:
use the command crontab -e to create this line in your crontab:
* * * * * set > /tmp/myvars
Wait a few minutes, go back into crontab -e and delete that entry.
Use the set command from the command line to see what variables and aliases exist.
Compare that with that you see in /tmp/myvars You have to change how your C code executes by changing the variables and aliases the cron job runs with.
If you are running the cron job in someone else's crontab, then you have a bigger problem. Check file permissions on get1Receive1.c. and the directory it lives in. That other user (the one who wons the crontab) has to have permissions set on your directory and get1Receive1.c so the job can run.
Example crontab entry:
0 10 * * 1-5 /path/to/get1Receive1.c > /tmp/outputfile
Read /tmp/outputfile to see what you got. You are using printf in your code. printf only writes to the controlling terminal. There is no controlling terminal, so redirect the printf stuff to a file.
Last effort on this problem:
Check return codes on EVERYTHING. All C functions like fread(), any db function, etc. If a return code gives a fail response ( these are different for different function calls) then report the error number the line number and function - gcc provides LINE and func. Example:
printf("error on line %d in my code %s, error message =%s\n", __LINE__, __func__, [string of error message]);
If you do not check return codes you are writing very poor C code.
CHECK return codes, please, now!
Permission wise you could have two issues.
1. The 'c' file's permissions don't allow who you are running it as to run it.
2. You are running the cron with a script which doesn't have permissions.
Here's a helpful post: How to give permission for the cron job file?
The fact that you are running a 'c' file and referring to it as a script makes me think you're using C shell and not writing it as a C language program which would need to be compiled and have the generated executable run by the cron. If you're not using gcc or have never called gcc on your 'C' script then it's not C and call it C shell to avoid confusion.
