I am trying to build an MQTT system on a raspberry pi. I was studying about MQTT and read about it a lot. I found a set of MQTT blocks in the Simulink Raspberry Pi Hardware Support Package that I assumed I could directly use. I configured an MQTT server and got all the right credentials and everything but I am now stuck on one part that has left me stumped.
I keep getting this error saying that "fatal error: MQTTAsync.h: No such file or directory". I have looked a lot trying to find anything that might help me but I couldn't. I don't know where to get the necessary files that I need or if there is any solution to sort this. I'm sharing the entire snippet of the error if that is of any help. Thanks in advance.
I apologize I'm not able to get to the whole error into a code block

I am writing an eBPF Code.
I need to use the function bpf_obj_pin, declared in kernel files:
tools/lib/bpf/bpf.c
tools/lib/bpf/bpf.h
Refer from here: https://elixir.bootlin.com/linux/latest/ident/bpf_obj_pin
So from the same files, I found out that I had to include this in my header.
#include <bpf/bpf.h>
But I get the following ERROR:
clang -O2 -target bpf -I/usr/include/x86_64-linux-gnu -c bpf1.c -o bpf1.o
bpf1.c:10:10: fatal error: 'bpf/bpf.h' file not found
#include <bpf/bpf.h>
^~~~~~~~~~~
1 error generated.
makefile:21: recipe for target 'bpf1.o' failed
make: *** [bpf1.o] Error 1
This is somewhat similar but doesn't solve my problem.
I am running a perl script on a web server. I am getting the error in the httpd error log file:
/usr/bin/perl: symbol lookup error:

undefined symbol:
bp_sw_read_Blast_file_CompMat, referer: http://XX/model_select.pl
[Line breaks added for readability]
I checked some of the forums and did this:
cpanp -i /usr/local/lib64/perl5/auto/Bio/Ext/Align/Align.so
ERROR '/usr/local/lib64/perl5/auto/Bio/Ext/Align/Align.so' does not contain an author part

No such module: /usr/local/lib64/perl5/auto/Bio/Ext/Align/Align.so
No modules found to operate on!
Nothing done
I checked, Align.so exists in the path shown in the error message
Can someone please help me solve the problem. Thanks much ! :-)
I tried to install Orion context Broker on Ubuntu 14.04 with Alien but when I do contextBroker start it says:
contextBroker: error while loading shared libraries: libboost_thread-mt.so.5: cannot open shared object file: No such file or directory
I couldn't find where is the error then I tried to install with all the dependencies from the instructions in Git, but when I try to do the make it makes an error:

I have the mongo's driver installed, how can I solve this?
Finally I compile a new driver from https://github.com/mongodb/mongo-cxx-driver/releases and it continues compiling until:

Is a problem in a file of Orion Context Broker?
I think that it could be a problem with de mongo's driver again but I try to install another one older and it doesn't work. I also think it can be a problem with de -mt libraries that doesn't exist in boost anymore, but nothing that I try until now works.
I've installed Orion CB using Ubuntu 14.04 LTS as host. I've also found some problems with libboost_thread-mt.so libraries. Solved this way:
Get & install packages
boost-thread-1.41.0-25.el6.x86_64.rpm
boost-system-1.41.0-25.el6.x86_64.rpm
boost-filesystem-1.41.0-25.el6.x86_64.rpm
and install them using alien. Then, the libraries were installed in “/usr/lib64” folder. To correct this (and CB is able to locate them): create a .conf file within “/etc/ld.so.conf.d/”, add a line (“/usr/lib64”) within and save it and quit and reload your configuration by calling (“sudo ldconfig”)
Hope this helps
So, here we have two questions in one. Let's start with the first one, about shared library not found:
Ask the broker where the library should be, using "ldd $(which contextBroker) | grep boost_thread).
After running this command, make sure the library is there. If it is not, but you have it elsewhere, you should be able to use the env var LD_LIBRARY_PATH to point to the directory where the library is found.
Now, for the second question, the mongo driver includes are not found. In my machine, I have them in /usr/local/include/mongo => I'm ok with the -I/usr/local/include directive to the compiler.
If you have your mongo driver installed elsewhere, you might need to add another 'include-directory' for the compilation. This would be done in the top-level CMakeLists.txt (I guess using 'include_directories' - I'm far from a cmake expert :-)).
When building, to see detailed information, compile like this:
% CPU_COUNT=1 VERBOSE=1 make install
Post the info again here unless you manage to solve your problems.
I am trying to simulate my VHDL file, but am running into the following error:
# ** Error: (vcom-11) Could not find work.lab1.
#
# ** Error: (vcom-1195) Cannot find expanded name "work.lab1".
#
# ** Error: Unknown expanded name.
# ** Error: VHDL Compiler exiting
# ** Error: c:/altera/12.1/modelsim_ase/win32aloem/vcom failed.
# Error in macro ./DE2_TOP_run_msim_rtl_vhdl.do line 8
# c:/altera/12.1/modelsim_ase/win32aloem/vcom failed.
# while executing
# "vcom -93 -work work"
I compiled the code successfully through both Quartus II and the ModelSim compiler before attempting to simulate. I do have a lab1 entity and architecture in my code (I can even see it in the Design Units tab of the Quartus Project Navigator), so I don't really understand this error. Anyone know what's causing this?
When the simulator is compiling the toplevel (DE2_TOP) it want to know how the used components are like. So, you should have compiled the lowerlevel components before compiling the upperlevel components.
What I do most of the times to fix this is compiling all components in correct order and then use the 'vmake' ('vmake -work work > work.vmake') command of Modelsim to generate a makefile out of the library (work). Once you have the makefile you can execute it with (make -f work.vmake). And all files will be compiled in order.
Note: Verilog is much more relaxed in those things...
