I want to use doxygen to generate a qt supported .qch file.
I set up all parameters like GENERATE_QHP, QCH_FILE ,QHP_NAMESPACE in .cfg file, also, I set
QHG_LOCATION = "/home/marty/Qt5.14.0/5.14.0/gcc_64/bin/"
When I called doxygen project.cfg, the .html document was successfully created. But when it came to qhelpgenerator, it showed:
Running qhelpgenerator...
sh: 1: /home/marty/Qt5.14.0/5.14.0/gcc_64/bin/: Permission denied
error: failed to run qhelpgenerator on index.qhp
lookup cache used 2501/65536 hits=17469 misses=3200
finished...
I tried chmod 777 qhelpgenerator, index.qhp and the relevant files that I can think of, and ran
sudo doxygen project.cfg
the problem still existed. It has already bothered me a whole day.
Any ideas what might happen?
The documentation for QHG_LOCATION reads:
The QHG_LOCATION tag can be used to specify the location of Qt's qhelpgenerator. If nonempty doxygen will try to run qhelpgenerator on the generated .qhp file.
I think that the word QHG_LOCATION together with the description is a bit misleading here, it should include the name of the executable (analogous to e.g. HHC_LOCATION).
(Note: when starting external you can use doxygen -d extcmd to see which external commands are attempted to be started).

I'm new to R and RStudio and am currently taking online classes to learn more about data science. In one of my lectures, I'm being asked to create a project in RStudio prior to creating a repository in github and linking the project with git. In order to make a pre-existing project interact with git, the instructions in my lecture are telling me to navigate to the directory containing my project file by using the "cd" command followed by the location of the file and file name. My project file is currently located on my desktop so I typed in "cd ~ /Desktop/temporary_no_version_control" however, the directory doesn't seem to change and remains set on the original location of the file which was in Users/savannahkeiffer. Just so I could complete the assignment, I re-located the file to my user file and tried to follow the rest of the instructions which told me to type "git init" followed by "git add ." which is where I run into the "warning: could not open directory" warning.
I have a macbook which runs on OS X Maverick. I went into my system preferences > security and privacy and selected Full Disk Access where I manually allowed terminal to have access to all the files on my laptop. However, after closing and re-opening RStudio and attempting the commands again, I got the same error.
This is what I entered when I tried to change the directory
Savannahs-MacBook-Air-2:~ savannahkeiffer$ cd ~
/Desktop/temporary_no_version_control
Savannahs-MacBook-Air-2:~ savannahkeiffer$ git init
Reinitialized existing Git repository in
/Users/savannahkeiffer/.git/
And what I got when I changed the location of the project on my laptop in order to complete the assignment (after already giving access to terminal)
Savannahs-MacBook-Air-2:~ savannahkeiffer$ cd ~
/Users/savannahkeiffer/first project/temporary_no_version_control
Savannahs-MacBook-Air-2:~ savannahkeiffer$ git init
Reinitialized existing Git repository in
/Users/savannahkeiffer/.git/
Savannahs-MacBook-Air-2:~ savannahkeiffer$ git add .

Support/CallHistoryTransactions/': Operation not permitted

Support/com.apple.TCC/': Operation not permitted

Support/AddressBook/': Operation not permitted
And so on.. Is this a directory problem or a "git add ." command problem?
It looks like what happened is that when you typed the cd command, you left a space in between the tilde and the rest of the path, so you changed back into your home directory (represented by the tilde). Then, when you tried to do a git init, you tried to initialize your home directory as a Git repository, and then ran into the fact that macOS restricts some programs (in your case, not Terminal, but maybe still Git) from accessing certain directories.
In the shell, the tilde is just a fancy way of spelling the environment variable $HOME, which points to your home directory (in this case, /Users/savannahkeiffer), so it should immediately precede the rest of the path without a space in between.
The best thing to do in this case is switch into your project directory and then initialize a repository there:
cd ~/Desktop/temporary_no_version_control # note the lack of space after the tilde
git init
If you didn't intend for your home directory to be a repository (i.e., you're not storing your dotfiles in a repository there), then you will probably also want to remove the .git directory from your home directory by running rm -fr ~/.git. Be careful when typing this, as rm removes data without prompting and an unfortunate space could result in all your data being deleted.
Hello this was an issue I had also but in Windows. It was a simple fix, user error. I hadn't used gitbash for awhile so I forgot the process with working in gitbash. First mistake I made was after opening gitbash I directly executed the git status command. That's when I got the "warning: could not open the directory" message. You need to using the cd (change directory) command and the dir (directory) command to navigate to the folder that has the files you want to "git add ." and "git commit -m". Once you get to that folder you will be able to use the "git status" command to see your changes then proceed as normal. I had to post this because it took me hours before I realized what I was doing wrong. No other stack post pointed this obvious user mistake. Hope it helps you.
I was trying to deploy my application on Ubuntu 16.04. So i made a package with the following hierarchy -
Package
|
----bin
|
-----application
-----application.sh
-----Qt
|
-----necessary qt libraries
-----platforms
Here is the application.sh file -
#!/bin/sh
export LD_LIBRARY_PATH=`pwd`/Qt
./application
When i execute the application.sh file, it shows me that it cant find the libQt5MultimediaWidgets.so.5 file. But its in the Qt folder. Also when i print the ldd application from the application.sh file after exporting LD_LIBRARY_PATH it gives me following output -
Please check the marked parts. Can anyone please explain why the libraries from the Qt folder are not found even after exporting the LD_LIBARRY_PATH?
Edit:
So as suggested by #Zang, i have checked the debug log and here it is -
Please check the marked parts.
It seems like its actually trying the actual libQt5MultimediaWidgets.so and then report that its unable to find it. Can anyone please help me understand whats happening here?
Edit-2: As per suggestion from #Tarun, i have ran ls -al on my Qt folder. Here is the output -
All files in Your Qt directory are actually simlinks to non-existing files in the same directory, therefore they cannot be found.
If you look at the output of your ls -al
These are soft links that you have. Your softlink libQt5MultimediaWidgets.so.5 points to libQt5MultimediaWidgets.so.5.9.2 in the same directory and the file is not there at all. So you need to either set the correct softlink path or have the file in same directory
First
Could it be that the pwd is not where you assume it is?
You could try adding
# Figure out where the application.sh script is located
scriptpath="$( cd "$(dirname "$0")" ; pwd -P )"
# Make sure our pwd is that location
cd "$scriptpath"
in the top of your script (assumes bash shell, from here)
By doing this all relative paths to Qt folder will be valid.
Second
Maybe you should considder exporting your new LD_LIBRARY_PATH, like so (from here):
LD_LIBRARY_PATH=whatever
export LD_LIBRARY_PATH
Third
It may be useful to run ldconfig command for ld to update after changing the variable (from here):
sudo ldconfig
The file libQt5MultimediaWidgets.so is not present in /Desktop/package/bin/Qt according to the screenshots shown.
I know this is a basic question but I'm missing something fundamental about makefiles.
Take this simple rule/action:
doc: ${SRC_DIR}/doc/dir1/file1.pdf ${SRC_DIR}/doc/dir1/file2.pdf
cp $? ${DEST_DIR}/doc/
the first time I run it, it copies file1.pdf and file2.pdf to the destination/doc directory. Perfect. I'm expecting the next time I run it, for it to do nothing. The source files haven't changed, aren't they a dependency? But when I run I get :
cp : cannot create regular file ..... :Permission denied.
so, 2 questions:
1) Why is it trying to do it again? When I run make -d I see it eventually says: No need to remake target .../file1.pdf and .../file2.pdf but then
it says : must remake target 'doc'
If it doesn't need to make either pdf file, why does it need to make doc?
2) say the pdf files had changed in the source, they are read only though, so it gets the permission denied error. How do you get around this?
A make rule:
target: preqreq0 prereq1...
command
...
says that target needs to be (re)made if it does not exist or is older than
any of the prerequisites preqreq0 prereq1..., and that target shall be
(re)made by running the recipe command ....
Your rule:
doc: ${SRC_DIR}/doc/dir1/file1.pdf ${SRC_DIR}/doc/dir1/file2.pdf
cp $? ${DEST_DIR}/doc/
never creates a file or directory doc, so doc will never exist when
the rule is evaluated (unless you create doc by other means), so the recipe
will always be run.
The kind of target that I believe you want doc to be is a phony target,
but you are going about it wrongly. A reasonable makefile for the purpose would
be:
SRC_DIR := .
DEST_DIR := .
PDFS := file1.pdf file2.pdf
PDF_TARGS := $(patsubst %,$(DEST_DIR)/doc/%,$(PDFS))
.PHONY: doc clean
doc: $(PDF_TARGS)
$(DEST_DIR)/doc/%.pdf: $(SRC_DIR)/doc/dir1/%.pdf
cp $< $#
clean:
rm -f $(PDF_TARGS)
I recommend The GNU Make documentation
As for your second problem, how to overwrite "readonly" files, it is unrelated to make.
You cannot overwrite files to which you do not have write permission, regardless
of the means by which you try to do it. You must get write permission to any files
that you need to write to. It is a system administration matter. If you do not
understand file permissions you may find help at sister-site Unix & Linux
or serverfault
I am trying to run a programme on a debain dedi. Using the following code.
java -cp bin:lib/* rs.Server false 43594
However it gives me a file not found error (even though the files are present). I fixed this error in intellij by picking the $MODULE_DIR$ option. Is there a equivalent to this in unix terminals?
The problem looks to be that the directory your are in when you run the command is wrong. You either need to cd to the directory containing the bin and lib directories or specify the full path to the directories in the command line.
The following line appears as soon as I open terminal. What does this mean?
-bash: exort: command not found
This must be because in your ~/.bash_profile, ~/.profile, etc. there is a line saying exort instead of export.
Look for it in your home directory with:
grep "exort" ~/.*
I have no idea what exort is - perhaps a misspelling of export? To track down this error, you'll need to examine your login scripts. You can use a text editor (i.e. vi) to view the files in question and search for exort. I recommend looking in the following files, if they exist:
~/.bashrc
~/.bash_profile
~/.profile
/etc/bashrc
/etc/profile
/etc/profile.d/*
