When I use the UI of IDA to load a binary file with debug info, a window which prints "DWARF info found" will come out and I can choose "Import file names/line numbers" to present the correponding source lines of certain addresses.
However, I find when I using command line to run ida like "idat64 -A -S'script' binary_name", idat64 would not load the DWARF without specific setting.
I tried to find possible setting to load the DWARF infos but failed. Could someone help me solve this problem?
I want to use
ida_nalt.get_source_linnum
and
ida_lines.get_sourcefile
to export the address-to-line mapping informations.
However, without loading the DWARF info, running the scripts will only print invalid results.

I want to use Tesseract to recognize code. It is said on their website that I can disable dictionaries by setting both of the configuration variables load_system_dawg and load_freq_dawg to false.
However I haven't been able to do it correctly.
$ tesseract img.jpg output.txt --oem 0 -c load_system_dawg=0 load_freq_dawg=0
read_params_file: Can't open load_freq_dawg=0
Error: Tesseract (legacy) engine requested, but components are not present in /usr/share/tesseract-ocr/4.00/tessdata/eng.traineddata!!
Failed loading language 'eng'
Tesseract couldn't load any languages!
Could not initialize tesseract.
Any ideas on best ways to handle it?
First of all, get eng.traineddata with the legacy engine or other OCR engine value (OEM).
Next, read the output of tesseract --help-extra carefully:
-c VAR=VALUE Set value for config variables.
Multiple -c arguments are allowed.
I am trying to export the DataStage job designs with executables. Below is the screenshots I use to export from the GUI.
This is the two commands I use:
dsexport.exe /h=XX /U=XX /p=XX projectXXX /job=XXX jobname.dsx
dsexport.exe /h=XX /U=XX /p=XX projectXXX /job=XXX /EXEC /APPEND jobname.dsx
The file generated from commands is bigger than the one from GUI. Anyone knows how to use dsexport command to export jobs with the options as in the GUI screenshots. much appreciated. I am using Designer V8.5.
JS
C:\IBM\InformationServer\Clients\Classic>dsexport /d={ip address of server} /u={user id} /p={password} /job={job to export} {Project where job is located in} {FileName.dsx}
try this, it will export a single dsx file with all informations
P.S.I am using version 11.3
As you can see GUI is excluding some read-only files which is not excluded in command line this is why the file size difference is there.
You have "Include Dependent Items" unchecked in the GUI. The command line will include dependent items by default (i.e. shared containers or routines). You can disable this behaviour on the command line by using the /NODEPENDENTS command switch.
I am trying to generate a bulkloader.yaml file in this way
appcfg.py create_bulkloader_config --filename=bulkloader.yaml --url=http://your_app_id.appspot.com/_ah/remote_api
but I get this error
File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/bulkloader.py", line 3839, in CheckOutputFile
raise FileExistsError('%s: output file exists' % filename)
I can't manage to find where such file is
consider I am using Eclipse PyDev on Mac Os through the GoogleAppEngineLauncher
Couple of things:
1) you are missing the --application=s~your_app_id tag
2) What directory are you in when you run this? If you are not sure run cd path/to/where/you/want/it
3) You can always try to find it using Mac's Spotlight, in case you are not sure where it saved.
Setup:
Windows 7 Enterprise.
Matlab 7.10.0 (R2010a).
mcc compiler: Microsoft Visual C++ 2008 Express.
What's happening:
My project runs fine when running it through Matlab, but when trying to run the .exe through the command prompt after using mcc to compile, the command prompt generates an error.
The mcc command I issue is:
mcc -m -v STARTUP1.m -o EXE_REDUC
The error I receive in the command prompt is:
??? Error using ==> textscan
Invalid file identifier. Use fopen to generate a valid file identifier.
I have a file called LoadXLS.m that loads and reads a .csv file using:
fid = fopen(file,'r');
temp_data = textscan(fid,...args...);
And then I process temp_data.
The csv file I'm trying to load is called spec.csv. It is located two directories down from where I have STARTUP1.m stored. The location of STARTUP1.m is also the place that the mcc generated files are stored to. I have used the pathtool to "Add with subfolders" this location, but am aware that those locations are not transferred to mbuild when compiling.
What I've Tried:
I have gone in and added print statements to print the value of fid to make sure it is valid. When I run it in Matlab, it has a valid value, however when I run in the command prompt it always returns an invalid value of -1.
I have removed all addpath() calls, I have tried adding the STARTUP1.m directory to the mcc ctf archive using:
mcc -m -v -a 'C:\Users\...path...\STARTUP1.m_location' STARTUP1.m -o EXE_REDUC;
However when I do this, I get a different error when running in the command prompt:
Cannot open CTF archive file
'C:\...path...\AppData\Local\Temp\mathworks_tmp_7532_28296'
or
'C:\...path...\AppData\Local\Temp\mathworks_tmp_7532_28296.zip'
??? Undefined function or variable 'matlabrc'.
To fix this, I've tried adding the pragma
%#function matlabrc
to the top of STARTUP1.m to try and enforce its inclusion, but had no success.
I also copied the spec.csv file to a new directory in the ctfroot and changed
fid = fopen(...)
to:
[tempFile, message] = fopen(fullfile(ctfroot, 'Added Config Files', ad.spec_file));
The message is:
message is: No such file or directory
Objective:
Rearranging file locations is a sufficient workaround while the exectuable only runs on my computer, however the idea is to take this standalone and distribute it to multiple people on many different computers. I would like to be able to have a top folder with a startup file and within this folder, have as many subfolders as the package requires. The startup file should be able to access all subfolders and files within them as necessary.
I read something about the exectuable actually running from a "secret location" on the machine here: http://matlab.wikia.com/wiki/FAQ
I would just like to be able to group one entire folder tree with all its files into a package containing the executable and be able to run it anywhere.
More info:
When I put the spec.csv file in the same directory as STARUTP1.m, it finds it fine using mcc without the -a 'path' option and using the following in the LoadXLS.m file:
[tempFile, message] = fopen(ad.spec_file,'r');
This project contains GUIs, generates PDFs, generates plots, and also creates a zip directory.
Thank you in advance.
It's the first time i try to generate a VCD and i am getting some troubles.
I have a testbench called bench_minimips.vhdl that contain the entity sim_minimips.
I want simulate it and get a VCD out of it.
i am typing the following command in the Modelsim shell:
vsim work.sim_minimips
vcd file myvcd1.vcd
vcd add -file bench_minimips.vhd/*
run
but if i open myvcd1.vcd in an empty file. What should i do to create the dump?
I tryed as well as sudgested in another forum the command:
wlf2vcd -o myvcd2.vcd vsim.wlf
but a error is generated.
I am really lost in understanding because all the websites i find tells you to use a TCL generated by altera or some other company and i do not have theyr content to look at.
Does someone knows what should i do?
Best,
Stefano
The -file parameter to vcd add is not used to specify signals but the name of the VCD (if you've created several).
What you want to do instead is to add objects in your simulation. For example:
vcd file myvcd1.vcd
vcd add -r /sim_minimips/*
