Sending a pcap file on port 0. I get the following error. Any fix would be appreciated!
The command used is:
sudo ./app/x86_64-native-linuxapp-gcc/pktgen -c 0X01 -n 1 --file-prefix=pg -w 4:00.1 -- -m 1.0 -T -P -s 0:~/Downloads/bigFlows.pcap
There are 2 obvious reasons for the failure.
Number of CPU cores for pktgen to work is 1 + number of ports in use
you have extra argument in comamnd executed in pktgen.
Checking the link, it show the command used is sudo ./app/x86_64-native-linuxapp-gcc/pktgen -c 0X01 -n 1 --file-prefix=pg -w 4:00.1 -- -m 1.0 -T -P -s 0:[~/Downloads/bigFlows.pcap]. You should not sue [] instead use 0:actual path to pcap.
Note: #SaifUllah during the live debug both core and pcap were show cased for you.
I am currently trying to install NIST's sclite, which is part of SCTK 2.4.0 (github or current version). I am attempting the install on Cygwin in bash. The installation is done using make.
What I've Done
I made a directory for the install and navigated to that directory
mkdir sctk2.4.0
cd sctk2.4.0
( You'll possibly need $ cd /path/to/dir/sctk2.4.0 .)
I cloned the project from github
git clone https://github.com/chinshr/sctk.git
navigated into the base folder
cd sctk
then I started following the instructions in the INSTALL file.
Running
make config
worked fine, but after typing
make all
I got the output that follows
(mkdir -p bin)
(cd src; make all)

I've looked at this SO post, but I've determined that the alignment.o file is not corrupted. Just in case, I tried a few make clean and even re-cloned the project from github, but I still get the same error.
Can anyone help me complete this installation, or at least get to the next step?

Note
I'm asking about this problem and then giving an answer to my own question. (I like that StackOverflow is allowing us to do that.) Hopefully, this will make it easier for people to help me with the problems I ran into further in the installation.
The next problem I ran into is discussed here. You can see this next problem in the answer to this problem.
This is the 'EASIER' solution.
Here are the details on what I called "the kaldi solution". Right now, it's just a list of commands without details. As shown here, these commands will install a sclite-2.4.10 directory under the $HOME (~) directory:
$ cd
$ git clone https://github.com/kaldi-asr/kaldi.git
$ cd kaldi/tools
$ extras/check_dependencies.sh
$ make -j $(nproc --all)
$ cp -R sctk-2.4.10 ~/
$ cd
$ rm -rf kaldi
$ cd sctk-2.4.10/
$ cp $HOME/.bashrc "${HOME}/.bashrc.$(date +%Y%m%d-%H%M%S).bak"
$ echo -e "\n\n## Allow access to sclite, rfilter, etc" >> $HOME/.bashrc
$ echo 'export PATH='"$(pwd)/bin"':$PATH' >> $HOME/.bashrc
$ source ~/.bashrc
See this question/answer for details on how to use it on Windows.
(See my comment under the question for the kaldi solution.)
The solution to this problem was in the README, as solutions often are. Note: There was another problem which came up after this problem was solved. See the bottom of this answer for help with that.
Here is the command I used to get the pertinent info from the README.
cat README | tail -13
and here is the pertinent info
64 bits Compilation
With big alignments, sctk needs to be compiled in 64 bits.
By default, the C/C++ software are compiled in 32 bits with the options (-Os)
but can be compiled in 64 bits, -m64 is added to the CFLAGS variable in:
src/asclite/core/makefile
src/asclite/test/makefile
src/rfilter1/makefile
src/sclite/makefile
Example of CFLAGS:
For OSX 10.4+: -fast -m64 -arch x86_64 -arch ppc64
So, I went to the makefiles listed (except rfilter1, see below) and changed the code there, replacing each -Os with -m64. Do this ONLY for the makefiles that are listed. I'll give an example for one of the listed files, but note you will have to do it for the others.
cd sctk
vim src/asclite/core/makefile
When the file was open, I found the line:
CFLAGS = -g -Os
which I changed to
CFLAGS = -g -m64
(pressed "i" to get into INSERT mode, made the change, pressed "Esc", then pressed ":wq" (Write and Quit) followed by "Enter")
I made the changes in all the listed files EXCEPT src/rfilter1/makefile, because that file had no -Os in it. This ended up being important, as the install wouldn't work if I had changed this file at all.
After this was completed, I ran make clean, but I DID NOT run make config, because this would have undone the changes we just make. I went directly to:
make all
This gets us past where we were before.
This problem was taken care of, but there was another problem:
In file included from main.cpp:20:0:
recording.h:122:36: error: template argument 2 is invalid
map<string, Filter::Filter*> filters;
^
recording.h:122:36: error: template argument 4 is invalid
which I asked about here.
AN EVEN EASIER SOLUTION - Taking advantage of a new, edited version of sclite
This is in case someone finds the answer here useful. I know there are no votes here, but I just got a trophy telling me this is my first question to get 1000 views, so I'll update my answer to show the easiest way to get things done.

Details
Since when I posted this in May 2018, there have finally been some updates made to the software:
I posted my question in May 2018, and the updates were made in Fall 2018. They partly fix the problems I ran into here, but some of the information in the README and some makefiles are useful to note here.
The 32- to 64- bit issue (changing -Os to -m64, as done above) was find-able via the README.
% cat -n README.md | grep -A 4 "64 bits Compilation"
61 **64 bits Compilation**:
62 With big alignments, sctk needs to be compiled in 64 bits. By default, the C/C++ software are compiled in 32 bits with the options (`-Os`) but can be compiled in 64 bits. To do so, `-m64` is added to the CFLAGS variable in `src/asclite/core/makefile`, `src/asclite/test/makefile`, `src/rfilter1/makefile` and `src/sclite/makefile`.

Since there was no -Os in src/rfilter1/makefile, I didn't make any changes.
I was able to finish the installation with no problem (including no failed tests). Here is my system info.

However, it seems that some other people trying to compile on Cygwin have had issues. Here is some more info from the README
% grep "Special Note to Cygwin users" README.md
*Special Note to Cygwin users:* it has been reported that compilation of `rfilter1` can fail in some case, please read the OPTIONS part of the `rfilter1/makefile` and adapt accordingly before retrying compilation.
Well, let's look at the makefile for rfilter1, and see what some of you might need to do.
% head -n 15 src/rfilter1/makefile | tail -7
########################### Options for compilation #########################
####### If you have an very new version of GCC, the strcmp* family of functions
####### is included in the distribution. Changing the value of OPTIONS to
####### be blank will diable the use of supplied versions of these functions.
####### In particular, this behavior has been noted on some versions of cygwin
OPTIONS=-DNEED_STRCMP=1 $(CPPFLAGS) $(CFLAGS) $(LDFLAGS)
So, if you have rfilter1 compilation problems, change the non-commented line to
OPTIONS= $(CPPFLAGS) $(CFLAGS) $(LDFLAGS)
I am trying to run some of my Go unit tests using "go test" but the test executable is built and run from my machine's %APPDATA%/local/temp directory. My PC has IT enforcement which blocks any unrecognized executable from being run other than from a pre-sanctioned directory (i.e C:/dev/projects"). All my Go source code are in that directory, including my *_test.go files. Is there a way to tell the Go test module to build and run from the current directory?
Yes you can.
Setting temp directory before executing the go test. By default temp directory environment variable gets evaluated in the order of TMP, TEMP, USERPROFILE, Windows directory; refer to msdn doc.
Basically it complies the go test under given temp directory and execute it.

Happy testing!
The resource has a not_if guard, and I've verified that the exit code from the command is non-zero. Yet the output of the chef run shows that the resource is skipped due to not_if.
The resource looks like
device_id = "/dev/xvdf"
execute 'yes | mkfs -t ext4 #{device_id}' do
not_if 'blkid -o value -s TYPE #{device_id} && blkid -o value -s TYPE #{device_id} | grep ext4'
timeout 1200
end
Sigh. Ruby doesn't interpolate in single-quote strings. Changed them to double quote and fixed the issue.
Can I get gdb to automatically load the binary that's specified in the core file?
Given a core file I now usually do:
gdb -c corefile
GNU gdb 6.8
...
Core was generated by `/path/to/binary'
Then i copy-paste that and run:
gdb -c corefile /path/to/binary
It seems like an unnecessary two-step process and yet I don't seen an obvious way of doing it based on the man page. Am I missing something?
You could just script it?
#!/bin/bash
gdb "`file "$1" | awk -F \' '{print $2}'`" "$1"
This is what I usually endup doing:
var=$(file corefile)
echo ${var##*from}
gdc() {
gdb -c "$1" "$(file "$1" | sed -r -e "s#.*execfn: '([^\']+)'.*#\1#")"
}
$ gdc corefile
