For enabling dtrace on Freebsd one can follow this link.
Ive tried it its working.

One things just in build instruction dont use the mapfile.Just skip it.By doing this the build will be successful

I am reposting this again in case missed out.
i have installed
sudo apt-get install libbluetooth-dev
and tried to compile btgatt-client.c from Blue5.54/tools/ with
gcc -o btgatt-client btgatt-client.c -lbluetooth
but get '#include "lib/bluetooth.h":no such file or directory'
What could be missing.I have tried move the files from '/usr/include/bluetooth'
the compilation folder but seems doesn't work. I am also curious where does this "src/shared/mainloop" from?
I am able to run the example and connect to nrf app but unable to compile the .c file.
The source files in BlueZ are not designed to be compiled singularly. Instead, you are supposed to build and install the entire BlueZ source, which in turn will compile btgatt-client.c for you. Please see the link below for instructions on how to build the entire BlueZ source:-
How to rebuild bluez
You will probably find that you need to install a lot of dependencies along the way, but you can either install these using sudo apt-get install <dependency> or try and not include it in the build. For example, to build BlueZ without systemd, you can do the following:-
./configure --disable-systemd
make
I hope this helps.
#Youssif Saeed. Thanks for the replies.
The good news is i have found out the cause.It seems the BlueZ bluetooth stack has an issue running in Raspbian Buster. I have downgrade the OS to Stretch and all seems up and running.
However i am trying gatt-client example and seems like not working when i set nrf app to advertising mode with exact UUID as in example. Or maybe i missed out certain part.Going to give a try with a simpler device like ESP32.
UPDATED
Thanks again guys.DBus gatt-client able to connect to BLMCU's. They key of operation is it needs to be paired > connected and read the BLE Server
I am a beginner C programmer, and recently I have run into a problem that I was unable to solve.
I am struggling to install and use a C library. The message error is:
My OS is Mac OS X and im try install the file with ".command" format.
Can someone help me install this library?
Thanks in advance.
More than help installing the library, you need help in understanding what's going on.
Someone gave you a command to run and you ran it, but they were assuming that you were using a different OS, like Ubuntu.
The first message "apt-get not found" is because you're running MacOS, which doesn't have an "apt-get" command.
The second error is because you also don't have wget.
The rest of the messages indicate a poorly written script file, since it blew up twice and still went on to truncate files and do other things.
While you're not going to be able to install apt-get, you might be able to find a compatible version of wget. If not, you can download whatever it was trying to get using your browser, since wget is typically used to automate web HTTP/HTTPS requests.
Without seeing the file, I don't know what the rest if the script was trying to do, but if you read it you should be able to figure out what it was doing, and do it manually.
An easier way to do all this is to install Virtualbox on your mac and run a copy of Ubuntu inside a virtual machine. Then you can run your class assignments without needing to rewrite them all.
I'm new to macports, and I'm really lost. I am trying to download PSPP (statistical software) via the GNU open software project using MacPorts, and installation completed without hiccups but I do not know how to proceed. How do I configure the application I just installed? Also, how do I get it to start up at automatically at boot?
I know this is a basic question, but I'd really appreciate the help! The MacPort QuickStart help questions are very confusing to me. Thanks!
The real question here is how to start the application. This largely depends on the application you installed, so PSPP in your case. Consult the documentation of PSPP (e.g. on their Website) to learn more.
In most cases, software installs a number of executables that you should run to start it. You can get a list of all files installed by PSPP using MacPorts by running
$> port contents pspp
Since this list will likely be huge, you can limit it to the locations where executables are usually installed:
$> port contents pspp | grep -E '/s?bin/'
For the PSPP port, it seems MacPorts also creates an .app wrapper. Check for /Applications/MacPorts/ – there should be a PSPP.app there.
I am making a simple operating system kernel and want to emulate it using bochs. Currently, I am using qemu as my emulator but want to switch over to bochs. I have downloaded and installed bochs in ubuntu but couldn't figure out a way to use it? Can anybody help me with that ? Any links or some way to get me started would be really helpful.
I needed the following .bochsrc run a minimal boot sector:
ata0-master: type=disk, path="main.img", mode=flat,
cylinders=1, heads=1, spt=1
boot: disk
display_library: sdl
megs: 128

I am trying to get memcached running on Windows. I have downloaded memcached stable latest and compiled it using Mingw under Windows 7. Configure failed with error,
checking for libevent directory... configure: error: libevent is
required. You can get it from http://www.monkey.org/~provos/libevent/
If it's already installed, specify its path using --with-libevent=/dir/
Then I downloaded libevent and compiled it. This produced 3 DLLs, libeventcore, libevent-extra and libevent-2.0.5.
I ran configure on memcached again with the option --with-libevent. But for some reason, it fails again with the same error. I have no clue on why it is failing. Can anyone help me to resolve this issue? Or is there a better way to get memcached running on Windows? I have seen lot of pre-built binaries for Windows. But all of them uses old versions of memcached. And AFAIK, Windows is officially supported by memcached in the newer versions.
I am using Windows7 64bit version with MinGW.
After you run make in libevent dir you get the files ready, but to make full use of it, they must be installed. So make install step is needed. If you configured it with a prefix, it will land in the directory of your choice. Otherwise it is /usr/local.
So maybe it's enough to run make install in libevent dir and run configure from memcache without parameters.
If you still have problems passing the configure stage, look at config.log. It shows the source file and the gcc command on which it failed.
Unfortunately successful configure is not everything. Later it fails on inclusion of sys/socket.h, netinet/in.h and netdb.h and perhaps also -pthread gcc parameter. I'm afraid it won't compile on mingw. At least not without a serious porting effort.
As I know, Never had an official Memcached port for Windows (Yes, there were few individual efforts. Last knowing porting effort can find on version 1.2.6 here) Best known Implementation for Memcached for windows on Couchbase with Memcached Bucket.
Late to the party I realize but the answer is to use:
$ export LIBS=-lws2_32
which will place $LIBS at the end of compile calls so that it is linked to libws2_32.a or winsocks2, but this probably means that your did not configure your build correctly and you will subsequent errors such as #include <sys/socket.h> header not found, etc.
