How to edit /usr/include/dlfcn.h in mac - c++

I have to edit this file /usr/include/dlfcn.h ( a compilation for a package, and it's maintainer told me to add some lines in this file). But I can't edit it. It's read only. I use sudo chmod 777 to change it's permission, but I don't have the permission to change it. I tried , for example, sudo -s, or su, But I don't have permission.
Using "sudo", "sudo -s" , "su" are all the ways I know to get permission to change a file. But I failed in this case. So who knows the solution, can you help me?
I use osx 10.11 and xcode 7.3.1

How did you continue after sudoing? You tried directly to open it with your editor and it didn't allow? (i.e. sudo gedit/vi/whatever dlfnc.h)

Failed to start a TensorBoard session in vscode due to the following error:

To launch tensorboard in vscode, I did the following steps:
select a python interpreter path
choose Python:Launch TensorBoard
and then I get this error:
We failed to start a TensorBoard session due to the following error: Command failed: conda activate ldl && echo 'e8b39361-0157-4923-80e1-22d70d46dee6' && python /home/cxy/.vscode-server/extensions/ms-python.python-2022.18.2/pythonFiles/printEnvVariables.py
CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If your shell is Bash or a Bourne variant, enable conda for the current user with
$ echo ". /home/cxy/anaconda3/etc/profile.d/conda.sh" >> ~/.bashrc
or, for all users, enable conda with
$ sudo ln -s /home/cxy/anaconda3/etc/profile.d/conda.sh /etc/profile.d/conda.sh
The options above will permanently enable the 'conda' command, but they do NOT
put conda's base (root) environment on PATH. To do so, run
$ conda activate
in your terminal, or to put the base environment on PATH permanently, run
$ echo "conda activate" >> ~/.bashrc
Previous to conda 4.4, the recommended way to activate conda was to modify PATH in
your ~/.bashrc file. You should manually remove the line that looks like
export PATH="/home/cxy/anaconda3/bin:$PATH"
^^^ The above line should NO LONGER be in your ~/.bashrc file! ^^^
I have tried the suggested command, which is
echo ". /home/cxy/anaconda3/etc/profile.d/conda.sh" >> ~/.bashrc
but it doesn't work, I still get the same error.
How can I solve this problem? Is there any suggestion? thanks in advance!!!
I have solved this problem!!!
Basically, it is caused by the latest version of Python and Pylance extension in vscode, all we have to do is simply downgrade the two extensiona and make sure vscode won't update them automatically.
So, do the following:
Downgrade Python extension and Pylance extension to eariler version, like v2021.10.xx and v2021.10.0 respectively.
Close the extension auto update in vscode, to ensure the downgradion in step1 works after restarting vscode.
Specifically, openSettings and search for the keyword update, do the following:
2.1. beneath the Update: Mode,select None instead of default
2.2. beneath the Extensions: Auto Update, select None instead of All extensions
After I did the above steps, the problem just disappeared. I can then launch tensorboard by shift+cmd+P and select Python:Launch TensorBoard.

Why am I receiving an 'sbserver not found' error when attempting to set up Google Safe Browsing Database?

I reached this GitHub repo. about google safe browsing database.
I have never used go, but I think it is required now. So I installed it using:
sudo apt install golang-go
Then, I followed the instructions in the GitHub page. I executed:
go get github.com/google/safebrowsing
But nothing installed in the path I was executing the command from. However, I proceeded to:
export PATH=$PATH:$GOPATH/bin
Then the manual says, run the following command (which is two lines, I executed the first line, then I press enter, then nothing changes. Then executed the second line separately:
go get github.com/google/safebrowsing/cmd/sbserver
sbserver -apikey $APIKEY
After executing the second line, I got this error:
Command 'sbserver' not found, did you mean:
command 'sxserver' from deb sx
command 'sb_server' from deb spambayes
command 'ssserver' from deb shadowsocks
Try: sudo apt install <deb name>
Can you please point to me what is wrong? How to install google safe browsing database?
Your PATH is wrong. You will find sbserver in $GOPATH/bin.
Try ${GOPATH}/bin/sbserver -apikey $APIKEY
If that does not work, then follow the Go installation instructions and make sure that your Go environment variables are correct.
GOPATH should look like /home/myname/go or something else that looks normal.
Your PATH should contain ${GOPATH}/bin

Running configure file in MinGW64: default build_alias command and default prefix not found

I'm using MinGW64 via an MSYS2 download and am currently trying to install the Solar Geometry 2 library (http://www.oie.mines-paristech.fr/Valorisation/Outils/Solar-Geometry/) for use. I'm following their install README, which states to navigate to the directory and "configure" (I've been typing "./configure". However, when I do so, I get the following message in my terminal:
$ ./configure
configure: loading site script /mingw64/etc/config.site
/mingw64/etc/config.site: line 13: config.site:13: default build_alias set to x6_64-w64-mingw32: command not found
/mingw64/etc/config.site: line 20: config.site:20: default prefix set to /mingw4: No such file or directory
configure: error: cannot find install-sh or install.sh in . ./.. ./../..
When I initially installed MSYS2 I set up the etc/fstab file as recommended. However, I'm quite new to MSYS so I'm assuming I botched something in my setup. I haven't edited anything in the config.site file mentioned in the errors, so I'm wondering if it's something in there.
Any help is greatly appreciated, thank you
No where in the directions for "Solar Geometry" do I see reference to MSys or MSys2.
I suggest you install the compiler toolchain and base development file. No idea if you editing /etc/fstab will cause problems. I do not normmaly edit it!
Install MinGW Package build packages. You might need more packages installed.
pacman -S --needed base-devel mingw-w64-x86_64-toolchain

Remote debugging with root privileges

i've got a trouble. Can't debug my program remotly due to can't call wiringPiSetupGpio(). I'm using netbeans to develop and debug my programs. I'm almost sure I need run debugging as root user but... how can I do that?
Is it possible to force netbeans start something like 'sudo gdb' insead of normal user? Or maybe to force my account in raspberry pi to call 'sudo gdb' when whatever try to call 'gdb'?
To force netbeans start gdb as root, you need to install netbeans as root. make sure your netbeans intall dir is in /usr/local and not in /home/[user_name]. You have to run netbeans installation as sudo
This is an old post but since I was facing the same issue I will post how I resolved this:
The problem for me did not seem to be the gdb, but the gdbserver running on the Raspi (or Beaglebone in my case).
I added a debug configuration to debug the application as root, therefore I added a script to the Beaglebone /usr/local/sbin/gdbserver and added the following lines:
#!/bin/bash
sudo /usr/bin/gdbserver $*
and made it executable:
sudo chmod a+x /usr/local/sbin/gdbserver
and see that in the file /etc/login.defs the lines
ENV_SUPATH PATH= ....
ENV_PATH PATH= ....
contain /usr/local/sbin. then in the debug configuration for the root execution I changed the command gdbserver to /usr/local/sbin/gdbserver. If that still doesn't work you might have to do this too:
sudo visudo
and add
<your_user> ALL=(root) NOPASSWD:/usr/bin/gdbserver
I hope this helps.

apktool build apk fails

I am experiencing very annoying problems with the application apktool problem.
I do not understand what i am doing wrong, or what the problem is.
I tried this on debian , and on linux mint. I used different versions of apktool,
resulting in the same error:
I: Checking whether sources has changed...
I: Checking whether resources has changed...
I: Building resources...

It seems it can not use aapt , but i read about apktool.
And it seems that aapt is build inside apktool , why is it not working ?
It seems there's some problem in building the resources while recompiling the apk.
what you can do is, when you decompile your apk use this command
apktool d -f -r apkfilename.apk
here -f is to replace previous decompiled apk's code and -r is to ignore the decompiling of resources.
this would prevent the resources from being decompiled and will simply copy the same resources when you recompile the apk.
In case you've been using v1 and now upgraded to v2, try manually deleting the framework file.
On windows 8 it's normally at C:\Users\YourName\apktool\framework\1.apk.
The file should be regenerated once you try to build something.
My problem was solved by deleting the \framework\1.apk, making a backup on the files I modified, ereasing the dir and decompiling the *.apk again, etc... (on linux, the path is home/[user]/apktool/...). After the update, apktool always loaded the old resource table. N
For me, I solved this problem by first clearing apktool's framework directory by typing in the terminal.
$ apktool empty-framework-dir
Afterwards I uninstalled apktool and related files by typing
$ sudo apt purge apktool
Then i went to https://bitbucket.org/iBotPeaches/apktool/downloads/ to get the latest jar file for apktool(apktool_2.5.0.jar as at the time of writing this).
On first run
$ java -jar apktool_2.5.0.jar b <MyAPP.apk> #Without ><
it works.
since I work with apktool most of the times I needed a situation where I can run apktool from anywhere so I gave the jar file execute permissions by typing
$ sudo chmod +x apktool_2.5.0.jar
Afterwards I moved it /usr/bin/ by typing
$ sudo apktool_2.5.0.jar /usr/bin/
Definitely seems like the aapt PATH problem I had awhile back. Have you added aapt to PATH? If you still have problems, I have made a good apk kit in bash to avoid all these dependency problems. It supports apktool, signapk, zipalign,adb, fastboot, and heimdall. Check it out. All you need is a current java install.

There isn’t really enough information to give you a definite answer.
How ever you mentioned using different versions but the aapt issue was solved in version 2.4. Dependencies have been reduced to java version 1.8 or greater and the framework.
I use Debian and have the following:
Apktool 2.4
java version 11
Android framework
That’s all it took to get rid of the aapt path error.
The last error I came across was unrelated to aapt but was on the framework so I ran this command
apktool empty-framework-dir
And it solved it.
try to put the dir which include aapt file to your PATH. for example, export PATH=$PATH:./ ./apktool b
try to install ia32-libs and update latest version of apktool. (if possible restart)
apktool requires "ia32-libs" which is not available after Ubuntu 12.04. install ia32-libs
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
Download latest version of apktools.jar - https://bitbucket.org/iBotPeaches/apktool/downloads
apktool complete installation guide - http://ibotpeaches.github.io/Apktool/install/
I just encounter same problem when run apktool d foo.apk(decompiled success) and then apktool b foo(recompile failed with similar error).
The apktool tool above was installed via sudo apt-get install apktool on Kali Linux.
So, the solution was visits apktool's official site, e.g. https://connortumbleson.com/2017/01/23/apktool-v2-2-2-released/ (it's latest version at this time of writing), download it, md5sum it, e.g. md5sum apktool_2.2.2.jar to verify, then rename that apktool_2.2.2.jar to apktool.jar.
Then do java -jar ./apktool.jar b foo to recompile, it success without error (the generated apk located at ./foo/dist/foo.apk).
The main issue is apktool version you need 2.4.0
You must manually install it from ibotpeaches git hub
here some good info
https://www.youtube.com/watch?v=kB6s10Uwpcs
and a automated script for kali

In my mind the problem is how you install apktool...
I had the same problem and I did this and it worked very well:
For installation you first have to remove any installed apktool by the command:
sudo apt purge apktool
Then you'll have to install apktool but in a different way.
To continue save the link bellow as apktool in a directory.
[https://raw.githubusercontent.com/iBotPeaches/Apktool/master/scripts/linux/apktool]
Then open this link below and download the latest apktool.jar file: https://bitbucket.org/iBotPeaches/apktool/downloads/
Then rename the file as apktool.jar
After that give both files the permission by the command:
Sudo chmod -x apktool.jar
And for the saved script:
Sudo chmod -x apktool
At the end copy both files in the directory:
/usr/local/bin
By the command:
Sudo cp apktool.jar /usr/local/bin
And the script file:
Sudo cp apktool /usr/local/bin
After that try running apktoolin the terminal.
The solution is to include your apktool directory into your system PATH.
