How to resolve error in debugging a program in totalview?

I installed TotalView on Ubuntu. For the begining I just tried to debug a very simple Hello Word program in but I got the following error:
"Fatal Error: Can't set up library cache directory -- cannot debug this target. Do you want to run the TotalView Diagnostic Tool?"
I don't know what is the library cache directory. Any idea about the library cache directory in ubuntu can be helpful.

Getting 'Permission Denied' error trying to generate Doxygen documentation

I am trying to run the doxygen command (I'm using Windows 10 with Cygwin and the packages Doxygen, Graphviz and the g++ compiler installed with it) and, at the end of the execution, I get the following error:
Error: Could not open "/cygdrive/c/Users/alexl/Desktop/src/DOC/html/graph_legend.png" for writing: Permission denied
error: Problems running dot: exit code=1, command='dot', arguments='"/cygdrive/c/Users/alexl/Desktop/src/DOC/html/graph_legend.png" -Tpng -o "/cygdrive/c/Users/alexl/Desktop/src/DOC/html/graph_legend.png"'
I also get sixteen other warnings with the following structure:
Warning: Cannot open file <filename>.png for writing
I've been searching for hours why this may occurr. I've tried running command prompt as an administrator, but the error still persists. Any help would be greatly appreciated.

MiXiM building no such file or directory error

I failed to build the MiXiM on Ubuntu 14.04.3 and OMNet 4.6, the error message is: ”fatal error: Mac80211Pkt_m.h: No such file or directory”. From the manual of OMNet it can be found that the file Mac80211Pkt_m.h should be generated automatically by the compiler during the building process, but it was shown by the error message that the file was not generated automatically. I am confused about the problem, how can I solve this? Can anyone help me? Thanks!
I faced the same error message. Here is how I bypassed the problem:
Extract "mixim-2.3.tar.gz" (tar xvzf mixim-2.3.tar.gz)
Change into the directory just extracted (cd mixim-2.3)
Execute "make makefiles"
Start the build by "make"
Import the just built project using the omnet++ IDE

Getting Smarty errors on new 2.2.14 install

I am trying to install version 2.2.14 on a new LAMP server. However, on the first Setup page I am getting the error:
include(/home/mysite/public_html/core/cache/setup/smarty/a2b9296b2cd7b74ba799b1e2f585cb6d0e3eb1d8.file.language.tpl.php): failed to open stream: No such file or directory in /home/mysite/public_html/core/model/smarty/sysplugins/smarty_internal_template.php on line 422
I have tried opening up permissions for all the files in smarty to no avail.
I am really not sure what to do or how to fix this. Can anyone shed some light on this?
I found that for whatever reason I was unable to delete the core directory - even with FTP. This was causing conflicts. I renamed it to coreOLD and tried again and it works. Weird.

Matlab Libopencv error using Linux

I am running into errors with opencv. I downloaded a package online and compiled each of the folders by cd into them and running make through the command line. But when I try using one of the functions, I run into this error: libopencv_core.so.2.3: cannot open shared object file: No such file or directory
The file its trying to reach is indeed there, since I checked this, but for some reason its saying its not. I am pretty bad at figuring out path problems but I think this is one of them. Can anyone tell me how to fix this? Thanks
