Hello I've installed MinGW with Msys and there is no mkdir in bin folder of Msys.
Why?
How can I use Netbeans to compile C++ code?
I get such error
mkdir -p build/Debug/MinGW-Windows
make.exe[2]: mkdir: Command not found
when trying to compile in Netbeans 8.1
Several commands are missing when installing MinGW and Msys.
E.g. when running the "/postinstall/pi.sh" as recommended in the "Getting started" guide, the following commands were missing:
- mkdir
- cp
- rm
I fixed it by downloading:
https://sourceforge.net/projects/unxutils/?source=typ_redirect
and then copying the missing commands to C:\MinGW\msys\1.0\bin
Of course I did a search initially to see if the commands should hide anywhere else in the MinGW/Msys filetrees, and they didn't.
I also copied useful commands like:
- ls
- rmdir

I was setting up DWM window manager on debian, but when conpiling it, it came up with an error.
I installed it, then tried to run it with make clean install, but it did not have the make command. I installed it with sudo apt-get install -y make. I tried to run make clean install, but it came up with the error:
make: cc: No such file or directory
make: *** [Makefile:18: drw.o] Error 127
Help?
Doing just make install (sudo if required) the first time should fix the error.
As to why it happens — you probably have a custom Makefile or your rm binary does not understand the -f flag. The upstream Makefile has the following under the clean target:
clean:
rm -f dwm ${OBJ} dwm-${VERSION}.tar.gz
Ensure that your Makefile also passes the -f flag to rm (which means "ignore nonexistent files").
I am using Ubuntu 14.04 LTS. After updating VSCode to v.1.53.0 I am getting following message on opening VSCode:
/usr/share/code/bin/../code: /usr/lib/x86_64-linux-gnu/libxkbcommon.so.0: no version information available (required by /usr/share/code/bin/../code)
On giving command code --verbose I get following logs: logs
I cannot update current Ubuntu version due to limited admin rights.
If you run code --verbose you will see real problem:
[main 2021-04-16T11:44:45.671Z] Main->SharedProcess#connect
/usr/share/code/code --verbose --no-sandbox: relocation error: /usr/share/code/resources/app/node_modules.asar.unpacked/spdlog/build/Release/spdlog.node: symbol _ZNKSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE7compareEPKc, version GLIBCXX_3.4.21 not defined in file libstdc++.so.6 with link time reference

echo _ZNKSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE7compareEPKc | demangle
So to run visual studio code on Ubuntu 14.04 LTS
You just need to copy libstdc++.so.6.0.28 and libstdc++.so.6
to /usr/share/code from ubuntu 20.04 LTS
You can get libstdc++.so.6.0.28 (md5=0e7d34a60136c0cd150917ed099980f2) for example from this deb file
Here simple script to do it for you
#!/bin/sh
wget https://mirrors.wikimedia.org/ubuntu/ubuntu/pool/main/g/gcc-10/libstdc%2B%2B6_10.2.0-5ubuntu1~20.04_amd64.deb
dpkg-deb -R libstdc++6_10.2.0-5ubuntu1~20.04_amd64.deb .
sudo cp -P usr/lib/x86_64-linux-gnu/* /usr/share/code/
file version changed in wikimedia.org so new script:
#!/bin/sh
wget https://mirrors.wikimedia.org/ubuntu/ubuntu/pool/main/g/gcc-10/libstdc%2B%2B6_10.3.0-1ubuntu1~20.04_amd64.deb --no-check-certificate
dpkg-deb -R libstdc++6_10.3.0-1ubuntu1~20.04_amd64.deb .
sudo cp -P usr/lib/x86_64-linux-gnu/* /usr/share/code/
md5sum of new libstdc++.so.6.0.28 604ec2999aeb3aadd0e96103fd4b5e5d
Then just type code
ps: very good font for vscode JetBrains Mono
I downgraded my VSCode to lower version. Apparently you can access previous versions of VSCode from it's website but the link's font was too big form me to see.
Still if someone does come across any other alternative please share.
Leaving this here for others.
I tried to follow along the Perfect screencast from RayWenderlich on a Mac. On Perfect Asistant (2nd screencast), he showed using Perfect Assistant, we could just click on the Build Linux and it will build on Linux given we have installed the Docker.
In my case it started to compile then it failed with error that current module cache path and the module cache path the PCH was compiled was not the same. I don't know how to update the module cache path just for Linux.
Here are the console output:
Starting Linux build of /Users/hange/Developer/RayWenderlich/Practices/ServerSide_Perfect/hello-perfect-assistant
Using image perfectassistant/helloperfectassistant
Using image perfectassistant/helloperfectassistant
Compile COpenSSL openssl.c

error: PCH was compiled with module cache path '/perfectbuild/.build_lin/debug/ModuleCache/5QE1M5WG4ATI', but the path is currently '/perfectbuild/.build/debug/ModuleCache/5QE1M5WG4ATI'
1 error generated.
Failed: systemError(1, ":0: error: build had 1 command failures\nswift-build: error: exit(1): /swift-3.1.1-RELEASE-ubuntu16.04/usr/bin/swift-build-tool -f /perfectbuild/.build/debug.yaml\n")
In Perfect Assistant project editor window, press and hold button "Build" and choose "Clean Project", then try building it once more.
Alternatively, press and hold button "Open" then choose "Open Terminal", and run commands below:
$ rm -rf .build*
$ rm -rf *.pins
$ rm -rf *.resolved
Then try building.
If you still couldn't understand what was going on, try opening a terminal window and run scripts below:
$ cd "/Users/hange/Developer/RayWenderlich/Practices/ServerSide_Perfect/hello-perfect-assistant"
$ rm -rf .build*
$ rm -rf *.pins
$ rm -rf *.resolved
Which should perform the same task as the second solution.
I have built a project using cmake (LLVM project) and tried to install it by issuing the following command:
$ cmake3 --build . --target install
If I run it using root then there is no problem and the files will be installed under the directory /usr/local/.
My problem is when I want to install the project using normal user.
I get the following error:
CMake Error at cmake_install.cmake:36 (file):
file INSTALL cannot set permissions on "/usr/local/include/llvm"
I have changed the permission of directory /usr/local/ to 777 recursively, and their ownership to root:wheel and I added my normal user to group wheel. But I still cannot install the files into the /usr/local/ directory.
The main issue is about building project in Eclipse which fails at "Build Install" command.
chmod 777 -R / is a very scary command. I've destroyed a system once by doing that.
The philosophy I use for this is:
If I need to deploy something through my IDE to debug or test before packaging, I deploy it locally within my home directory.
I only install stuff to my system (outside of home) if it has been packaged first (*.deb, *.rpm, *.tar.gz) so that I can remove it without problems.
For me, I do this with:
cmake $src
cmake --build . --target install -- DESTDIR=stage
This will configure my project, make it, then install it locally in a folder called ./stage which resides in my build directory. I can then run my executable from ./stage/usr/bin. Note that this only works if make is your generator.
Once I've tested it and I'm happy, I package it and deploy to my system or upload to a repository:
cpack
sudo dpkg -i <package>.deb
We should use USE_SOURCE_PERMISSIONS in our install function.
Example:
install(DIRECTORY "${CMAKE_CURRENT_BINARY_DIR}/Release/" DESTINATION "${CMAKE_CURRENT_BINARY_DIR}" USE_SOURCE_PERMISSIONS)
I have the following system:
Linux 64 bit LTS 12.04
I have multiple installations of opencv library on the system.
I want to know the procedure to remove all opencv libraries from the system.
I am having trouble while executing my program through Eclipse IDE.
Though I can build the project when I try to execute it, it gives the following error:
OpenCV Error: Assertion failed (k == STD_VECTOR_MAT) in release, file /build/buildd /opencv-2.3.1/modules/core/src/matrix.cpp, line 1364
terminate called after throwing an instance of 'cv::Exception'
what(): /build/buildd/opencv-2.3.1/modules/core/src/matrix.cpp:1364: error: (-215) k == STD_VECTOR_MAT in function release
Confusing thing is I am not able to find the path specified in the error i.e.
/build/buildd/opencv-2.3.1/modules/core/src/matrix.cpp
I am able to compile the same source code using command line tool gcc and using pkg-config.
However I am unable to do the same through eclipse IDE.
You can also uninstall by going to the "build" folder directory of opencv from terminal, and execute the following
make uninstall
cd ..
sudo rm -r build
sudo rm -r /usr/local/include/opencv2 /usr/local/include/opencv /usr/include/opencv /usr/include/opencv2 /usr/local/share/opencv /usr/local/share/OpenCV /usr/share/opencv /usr/share/OpenCV /usr/local/bin/opencv* /usr/local/lib/libopencv*
I remember I used this command a while ago to remove all opencv related things. It is interactive which promote you to remove the file. choose y or n depending.Take your time and be-careful
$> sudo find / -name "*opencv*" -exec rm -i {} \;
The correct way is cd /path/to/cv/build then sudo make uninstall. Of course you will have to have the source code with you
I tried the exec rm thing but nothing changed. Also FYI, sudo apt-get remove libopencv-* did not remove openCV for me
