MinGW pacman -Sys Unable to lock database - c++

To start Code and Compile C++, must install a compiler. For my case, it is MSYS2 through which MinGW is available. According to the installation guild mentioned on the website, I installed the software without any errors. Now I was supposed to update the package database and base packages by entering pacman -Sys but it has shown an error
error: failed to synchronize all databases (unable to lock database)
After searching online for a solution I found that deleting/removing the db.lck will work, for that, I used this command rm /var/lib/pacman/db.lck
but it showed another error. Right now there is no solution to this on the internet.
I've also pasted the terminal output of MSYS2 MSYS for refernce.
$ pacman -Sys
:: Synchronizing package databases...
error: failed to synchronize all databases (unable to lock database)
VIRAT#DESKTOP-97BS0AB MSYS ~
$ rm /var/lib/pacman/db.lck
rm: cannot remove '/var/lib/pacman/db.lck': No such file or directory
VIRAT#DESKTOP-97BS0AB MSYS ~
$ pacman -S --needed base-devel mingw-w64-x86_64-toolchain

$ pacman -Su
error: failed to init transaction (unable to lock database)
error: could not lock database: Permission denied

As I found there 2 solutions for this error. Try both :
Solution : 1
C:\Users\your_account_name\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\MSYS2 64bit
Run "MSYS2 MSYS" as administrator
Run the command : pacman -Syu
Solution - 2 :
C:\msys64\var\lib\pacman ( Go to the downloaded folder)
Delete the "db.lck" file
RESOURCES :
For solution 1 : Mr. Padro's (https://stackoverflow.com/users/18910613/pedro) solution helped me.

Fixing gcc undefined include<> by manually installing library

I am running the golang command "go get -t github.com/otiai10/gosseract" , causing the error tessbridge.cpp:5:10: fatal error: leptonica/allheaders.h: No such file or directory, #include <leptonica/allheaders.h>. That library is https://github.com/DanBloomberg/leptonica. How do I install it from source so that the gcc command will work.
Before that command was producing the error "gcc not found", but then I followed https://superuser.com/questions/1294343/install-gcc-in-git-for-windows-bash-environment to setup gcc on windows.
I have not been able to find any references for what gcc expects when it encounters an include<>, and where those files should be located on the file system for it to link properly. Is it possible to install this library manually?
Here is much simpler solution for you. There was no need to install gcc on git-bash.
Install MSYS2. Follow complete installation guide.
On MSYS2 console enter the following commands :
pacman -S mingw-w64-x86_64-gcc
pacman -S mingw-w64-x86_64-leptonica
Add C:\msys64\mingw64\bin to PATH.
First step can be further simplified if you use Chocolatey. Just run these commands in elevated powershell : (Ignore first command if choco is already installed.)
Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))
Reopen elevated powershell and run these:
choco install -y msys2 --params="/InstallDir:C:\msys64"
refreshenv
$env:Path += ";C:\msys64\usr\bin"
pacman -S mingw-w64-x86_64-gcc
pacman -S mingw-w64-x86_64-leptonica
[Environment]::SetEnvironmentVariable("Path", "C:\msys64\mingw64\bin;" + $env:Path, "User")

FreeBSD mount failed with error: operation not supported by device

I'm using freeBSD on VirtualBox on Windows10.
I want to mount on Windows. (HOST:Windows GUEST:freeBSD)
I run mount command but got an error below.
mount -t vboxvfs -w mp /mnt/vbox
mount: mp: Operation not supported by device
How can I solve this error?
What I did:
I install virtualbox-ose-additions-nox11-5.2.34 and virtualbox-ose-kmod-5.2.34,
then append vboxguest_enable="YES" and vboxservice_enable="YES" to my /etc/rc.config.
mp is normal empty folder on C:
I also install Guest Additions following Virtualbox's dialog.
this error caused by typo.
wrong : vboxfs
correct: vboxvfs
(I write correct command in this Question but I enter wrong command to my machine.)

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

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

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.

Installing the Qt SDK shows the message: cannot execute binary file

My environment is Linux 11.04
When I want to install Qt SDK
I download the SDK:qt-creator-linux-x86_64-opensource-2.5.2.bin
I move this file to /opt
and then
chmod u+x qt-creator-linux-x86_64-opensource-2.5.2.bin
./qt-creator-linux-x86_64-opensource-2.5.2.bin
but it shows that: cannot execute binary file
I think whether if it is because my Ubuntu is belong to 32-bit architecture
so I download qt-creator-linux-x86-opensource-2.5.2.bin
also move it to /opt file
and give the command:
chmod u+x qt-creator-linux-x86-opensource-2.5.2.bin
./qt-creator-linux-x86-opensource-2.5.2.bin
The same message still shows.
I give another command:
sudo ./qt-creator-linux-x86-opensource-2.5.2.bin
but it shows that Syntax error: ")" unexpected
how can I resolve this problem?
