When I run make kselftest-install, it shows the following error:
../../../lib/bpf/bpf_helpers.h:11:10: fatal error: 'bpf_helper_defs.h'
file not found
How to solve this issue? I'm using Ubuntu 20.04.
First, try to find the missing file in your kernel source code root directory.
$ find -name bpf_helper_defs.h
./tools/bpf/resolve_btfids/libbpf/include/bpf/bpf_helper_defs.h
./tools/bpf/resolve_btfids/libbpf/bpf_helper_defs.h
It shows that bpf_helper_defs.h exists, but in a different directory than bpf_helpers.h locates. So a simple way to solve this issue is to copy the missing file to the same directory.
$ cp ./tools/bpf/resolve_btfids/libbpf/include/bpf/bpf_helper_defs.h ./tools/lib/bpf/
Run make kselftest-install again, the error disappears.

I am trying to use setuptools to install a C++ library with a Pybind11 interface using CMake. For using CMake with setuptools, I am using the code in the following answer: Extending setuptools extension to use CMake in setup.py?
I am able to build the library by hand with cmake.
Unfortunately however, when executing pip install . in the root directory of my project, the build fails.
While the first call to cmake (self.spawn(['cmake', str(cwd)] + cmake_args)) finishes without any error, executing the second call (self.spawn(['cmake', '--build', '.'] + build_args)) gives me the following error:
/users/thoerman/miniconda3/envs/postproc_np_products/bin/../lib/gcc/x86_64-conda_cos6-linux-gnu/7.3.0/../../../../x86_64-conda_cos6-linux-gnu/bin/ld: cannot open output file /users/thoerman/postproc_np_products/build/lib.linux-x86_64-cpython-37/postproc_ops_cpp.cpython-37m-x86_64-linux-gnu.so: Is a directory
collect2: error: ld returned 1 exit status
gmake[3]: *** [/users/thoerman/postproc_np_products/build/lib.linux-x86_64-cpython-37/postproc_ops_cpp.cpython-37m-x86_64-linux-gnu.so] Error 1

gmake[1]: *** [CMakeFiles/postproc_ops_cpp.dir/rule] Error 2
gmake: *** [postproc_ops_cpp] Error 2
But when running the exact same commands on the command line inside the build_temp directory, everything works just fine.
Does anyone have a hint for me, what might be going wrong?
After further digging into the problem, I found the solution myself.
The problem was with the lines
extdir = pathlib.Path(self.get_ext_fullpath(ext.name))
extdir.mkdir(parents=True, exist_ok=True)
This created a directory for the target to be built. Building the target then failed, since there was already a directory with the same name.
I was able to solve it by replacing the second line as follows:
extdir.parent.mkdir(parents=True, exist_ok=True)
How do I correct/get rid of the following error? It prevents me from executing any lynis commands.
Output of "Sudo lynis show version" or any lynis command:
"Error: Unknown option 'ssl-certificate-paths-to-ignore' found (with value: /etc/letsencrypt/archive:)".
Background: Installed lynis, but couldn't figure out how to use it - got stuck on changing the parameters following a guide. Tried using another guide (https://adamtheautomator.com/lynis/), which included installing lynis again, and got this error
Tried purging and removing lynis, but got this error again after reinstalling, because thought the error had occured when I had first tried to install and configure lynis.
During the purge got:
"Purging configuration files for lynis (3.0.8-100) ...
dpkg: warning: while removing lynis, directory '/etc/lynis' not empty so not removed
Purging configuration files for menu (2.1.47ubuntu4) ...".
When I run xampp on fedora this error is showing up on application log

can anyone tell me how can I solve this?
it seems you're missing libnsl. install it through this command:
sudo dnf install libnsl
In case this doesn't work you can then download it manually:
Visit https://pkgs.org/
In the search box (pkgs.org of course) type libnsl.so.1 and choose the appropriate OS. The version shown might be higher e.g libnsl-2.28-9.fc29.x86_64.rpm, but it doesn't matter, the file needed is also included in this very package.
In the terminal, navigate to the directory where the .rpm was downloaded.
Type the following command to install it:
sudo rpm libnsl-2.XX-X.fc29.x86_64.rpm
Upon completion everything should be working fine.
A quick Google search returns this: https://www.reddit.com/r/Fedora/comments/8hlhlv/xampp_with_fedora_28/
The suggested fix is installing libnsl from this source:

I've bin trying to integrate Apache and with Django.
I downloaded the mod_wsgi-3.4 folder from the net and tried running the ./configure command from git bash.
I'm using dev c++ as my c compiler.
I get the following errors:
./configure: line 1877: apxs: command not found ln: creating symbolic link 'Makefile.in' to 'posix-apX.mk.in': No such file directory configure: creating ./config.status config.status:error: cannot find input file: Makefile.in
Can someone help me with this?
You can specify the location of apxs
./configure --with-apxs=/usr/local/apache/bin/apxs
