Building test project in Cocos2dx ( libgnustl_static.a: Permission denied ) - android-ndk

I am starting with cocos2dx.
Having setup the environment on Windows 8, I created a new project using create-android-project.bat.
Now when I build the project by using ./build_native.sh in cygwin, I get the following errors:
c:/android-ndk-r8b/toolchains/arm-linux-androideabi-4.6/prebuilt/windows/bin/../lib/gcc/arm-linux-androideabi/4.6.x-google/../../../../arm-linux-androideabi/bin/ld.exe: cannot find ./obj/local/armeabi/libgnustl_static.a: Permission denied
collect2: ld returned 1 exit status
/cygdrive/c/android-ndk-r8b/build/core/build-binary.mk:378: recipe for target 'obj/local/armeabi/libgame.so' failed
make: *** [obj/local/armeabi/libgame.so] Error 1
make: Leaving directory '/cygdrive/c/cocos2d-2.0-x-2.0.4/test/proj.android'
I figured that as it was a permission denied error, so I tried chmod 777 -R on both the cocos2dx directory and the NDK directory, but to no avail.
I can't figure out what to do now.

With NDK r8b, you don't need cygwin. Take cygwin/bin off the PATH and run ndk-build.cmd.
BTW, I strongly recommend to upgrade to NDK r9b. It's free.

How to not use /usr/local/lib after uninstalling self build package?

Initially, I had pcl-1.10 in /usr/(installed using sudo apt install libpcl-dev). Then I self-built pcl-1.12 in /usr/local/ for some reason. Now I uninstalled pcl-1.12 using sudo make uninstall and wanted to use the default pcl-1.10. But when I compiled my project, the error message showed
$ colcon build --cmake-args -DCMAKE_BUILD_TYPE=Release
Starting >>> lidarslam_msgs
Starting >>> ndt_omp_ros2
--- stderr: ndt_omp_ros2
make[2]: *** No rule to make target '/usr/local/lib/libpcl_surface.so', needed by 'align'. Stop.
make[1]: *** [CMakeFiles/Makefile2:80: CMakeFiles/align.dir/all] Error 2
make: *** [Makefile:141: all] Error 2
---
Failed <<< ndt_omp_ros2 [0.16s, exited with code 2]
It seems that the PATH stills points to the /usr/local/lib even if I uninstalled the package. Is there a way I can reset PATH to the global package path? For this case, I believe the pcl-1.10's libpcl_surface.so is in /usr/lib/x86_64-linux-gnu/libpcl_outofcore.so .
I am working on ROS2 and compiling the CMakeList.txt using colcon. So I can't modify the makefile. I assume it is a PATH problem.
A way is to use symlink to link all the .so file in /usr/lib/x86_64-linux-gnu/ to /usr/local/lib but I found it kind of stupid...

PULP SDK (platform-rtl)

I'm following the tutorial on PULP SDK build process "https://github.com/pulp-platform/pulp-sdk/blob/b38dabd571287b6183f17a2c5538382b9d3fe668/README.md". I'm blocked at the stage of SDK build when I tape the command "$ make all" and I can't understand what's mean these errors.
ImportError: No module named 'sphinx'
Makefile:56: recipe for target 'html' failed
make[2]: * [html] Error 1
Makefile:14: recipe for target 'all' failed
make[1]: * [all] Error 2
Reached EOF with exit status 2
FATAL ERROR: the command 'build' has failed
Makefile:6: recipe for target 'all' failed
make: *** [all] Error 255
I had a similar problem, this error is caused by not (correctly) installing the pulp-riscv-gnu-toolchain.
So you should first install this toolchain which can be found here https://github.com/pulp-platform/pulp-riscv-gnu-toolchain.
After that you should follow the steps for "Installation (Pulp)" and replace the command for make to sudo make.
Now you can return to your tutorial on PULP SDK build process.
In case you are still encountering the same error than you should execute this command which I found here cannot open libmpfr.so.4 after update on ubuntu 18.04
sudo ln -s /usr/lib/x86_64-linux-gnu/libmpfr.so.6 /usr/lib/x86_64-linux-gnu/libmpfr.so.4
" Bear in mind that this is just workaround which might trigger other issues for your case. However, this might save you the day in cases when the problematic program is just a mean to achieve something else."

PCL 1.8.0 installation: Compile error for including QtGui

I'm trying to build PCL 1.8.0 on my Ubuntu 14.04 machine from source, following these instructions. But every time I get the following error:
[ 73%] Building CXX object apps/CMakeFiles/pcl_manual_registration.dir/include/pcl/apps/moc_manual_registration.cpp.o

make: *** [all] Error 2
for locate QWidget I get amongst others the following output:
...
/usr/include/qt4/QtGui/QWidget
...
/usr/include/qt5/QtWidgets/QWidget
...
So how can I resolve the error and install pcl?
The problem happens because your configuration is trying to mix Qt4 and Qt5 during PCL build.
According to the link you've provided, PCL is suppossed so be built against Qt4 in this case.
Try to remove everything in release directory and re-initialize CMake config with correct version of Qt.
Like that (following provided example):
cd ~/Documents/pcl
rm -rf relese
mkdir release
cd release
cmake -DCMAKE_BUILD_TYPE=Release -DPCL_QT_VERSION=4 -DBUILD_GPU=ON -DBUILD_apps=ON -DBUILD_examples=ON ..
make

Kernel "make module_install" always gives error

Hey guys i am trying to command a custom system call.
I tried every step given on this website.
But whenever i enter the " make modules_install install " command i always get this error :
INSTALL arch/x86/crypto/aes-x86_64.ko
cp: cannot stat 'arch/x86/crypto/aes-x86_64.ko': No such file or directory
Can't read module
scripts/Makefile.modinst:30: recipe for target 'arch/x86/crypto/aes-x86_64.ko' failed
make[1]: *** [arch/x86/crypto/aes-x86_64.ko] Error 2
Makefile:1077: recipe for target '_modinst_' failed
make: *** [_modinst_] Error 2
I searched everywhere but i am unable to find any answer.
Looking forward for a solution.

build octave package from source

I want to install octaviz package in octave software.
From the documentation there is stated:
-You'll need octave 2.1.53 or later and VTK CVS to build octaviz. To compile octaviz, run ccmake . in the root directory of the source tree, then make and finally make install.
I first ran ccmake ., and it completed successfully after I installed some libs that I was missing.
But, the I ran "make" and it exits with the following errors:
>> make
[ 1%] Built target vtkWrapOctave
[ 1%] Building CXX object Common/CMakeFiles/octaviz.dir/octaviz.o
/home/user12345/octave/octaviz/Common/octaviz.cc:31:24: fatal error: octave/oct.h: No such file or directory
#include <octave/oct.h>
^
compilation terminated.
make[2]: *** [Common/CMakeFiles/octaviz.dir/octaviz.o] Error 1
make[1]: *** [Common/CMakeFiles/octaviz.dir/all] Error 2
make: *** [all] Error 2
Any idea what I am missing here?
You are missing the octave/oct.h header. This usually means that you don't have Octave installed. If you do have it installed, maybe you are missing the header files and shared libraries (if you are using Linux, did you install octave's -dev or -devel packaqes?) If you have them installed, you must have ran the configure script incorrectly. Either specify the correct options or set the CXX_FLAGS. If you don't know about compiler flags you probably should not change them and instead figure out how to install the octave libraries correctly.
