QUESTION
How do can extract the path of *.so
files and copy them to pwd
? I think they can be extracted by regex (between =>
and (
), but do not know how.
ANSWER
Answered 2021-Feb-22 at 22:30You can use awk '/=>/{print $3}'
.
This assumes no spaces in the path you want to extract and deliberately skips lines without the string =>
.
Then you can copy the files to your working directory in a couple different ways. Here is how you could with a while
loop:
QUESTION
I'm new in C++ and CMake projects. I write (with CLion) very simple application that uses mysql connector.
This require to install on system libmysqlcppconn-dev
. That is no problem on system where I build this but if I want to execute it on other system it fails because it needs shared library.
I want to include that library into my project.
For this in my project I created folder lib/static
and I copied files.

QUESTION
I am trying to move my rust server from Heroku to Google Cloud or AWS. Even though I like the simplicity of having a git push
build and deploy to Heroku with just a buildpack specified, the service is not cost effective for me.
I identified Google Cloud Run and AWS Elastic Beanstalk as potential alternatives.
First, I need to build a docker image with a static binary.
Thus, I added this Dockerfile:
...ANSWER
Answered 2020-Jul-15 at 00:36I cannot build your simplified Dockerfile as-is because I do not have the source files you reference in COPY statements, so I get "COPY failed" errors. You say "Building and running a new cargo default project with the x86_64-unknown-linux-musl target works" and indeed this Dockerfile (your simplified Dockerfile with the COPY commands removed) works fine for me:
QUESTION
Can anybody tell me why the shared library in my build path has a different set of dependencies to the shared library in my install directory?
...ANSWER
Answered 2020-Jul-01 at 13:32When you run ldd
, you see not only your direct dependencies, but the indirect dependencies of your dependencies. The libraries that your shared library depends on have different dependencies in the two different locations.
In particular, in one location it's resolving libpq.so.5 using
libpq.so.5 => /home/ciaran/vcpkg/installed/x64-linux/lib/libpq.so.5
while in the other it's
libpq.so.5 => /usr/lib/x86_64-linux-gnu/libpq.so.5
which in turn brings in different sets of libraries.

I tried to install Python 3 on my Ubuntu 16.04.4 LTS and while using apt
i found this:
ANSWER
Answered 2018-Aug-16 at 14:47No. apt-get autoremove will only remove files which are not in use by any installed package. Since all the packages you need to run your system have been installed apt-get autoremove will not remove any important system file.
If you require one of the package listed in the apt-get autoremove, you can always install it manually using:
QUESTION
I’m trying to establish TLS channel between a client and a web server that are under my control. Both the client and server authenticates themselves using certificates that I’ve created under private PKI scheme. Client key and certificate are stored on usb dongle type HSM. Python is the main application language.
I’m able to do all required crypto operations for my project using python-pkcs11
package such as AES encryption, HMAC signing, RSA signing, and etc. However, I couldn’t find a way to “bind” pkcs11 to any TLS library. What I mean is a “Pythonic” way of calling a function that handles pkcs11 layer and establishes a TLS channel. Requests does not support pkcs11. libcurl
has support for pkcs11 but it’s not implemented in pycurl
, neither pyopenssl
.
I’m able to do it openssl’s s_client CLI tool using engine api:
openssl s_client -engine pkcs11 -verify 2 -CAfile path/to/CA.pem -keyform engine -key "pkcs11:...;object=rsa;type=private" -cert path/to/client-cert.pem -connect localhost:8443
An example of what I’m looking for:
do_tls_with_pkcs(key=’pkcs11:URL’, cert=’cert.pem’, verify=’CA-cert.pem’)
As far as I could search around, no such library exists yet. Now I’m looking for a workaround.
I have read that if openssl, libp11, and python are compiled in such a way it is possible to abstract all of this, hence simple requests calls would go through HSM, transparent to application code. Although, I couldn’t find any material on how to do it.
...ANSWER
Answered 2020-Jan-24 at 19:22I faced a similar problem as I wanted to use a PKCS#11 token (YubiKey, PIV applet) along Python requests.
I came up with https://github.com/cedric-dufour/scriptisms/blob/master/misc/m2requests.py
It's imperfect, in the sense that it does not use connections pools and does not support HTTP streams or proxying - like requests's stock HTTPS adapter does - but it does the job for simple connections to backends that require mTLS.

mongod 4.0.3
...ANSWER
Answered 2018-Oct-17 at 08:12The problem was that I had manually deleted the /data/appdb/journal
file therefore it was unable to find that.
I found out this, when i tried a diffrent dbpath /data/appdb2
, it ran smoothly.

I am trying to run an executable in Ubuntu 16.04. but it is giving me below error.
error while loading shared libraries: libswscale.so.3: cannot open shared object file: No such file or directory
...ANSWER
Answered 2018-Apr-30 at 08:38You can add the path to the so file to LD_LIBRARY_PATH and check if the executable picks it up and works fine.
export LD_LIBRARY_PATH=pathToFolderWithLib:$LD_LIBRARY_PATH
./"executable"

QUESTION
I am a newbie trying to learn docker. I am trying to dockerize kafka installation and stuck with a non zero exit code. I would like to debug the issue and find out the reason. How to debug a docker file.
I tried executing the dockerd in debug mode by using dockerd -D
.But this did not give any detailed logging.
I am running my script inside a vagrant dev box. Is there any way i can execute the build in debug mode.
Below is my docker file.
...ANSWER
Answered 2017-Nov-19 at 03:54Always use apt-get install -y
so there are no user prompts.
The CMD
will need to run in the foreground as well and doesn't need to use a log file. Docker has a stdout/stderr logging interface accessible with docker logs CONTAINER
.
QUESTION
I am working on binutils addr2line and building by own library called address2lineutil.so and my machine already has binutils 2.22 installed installed in /usr/lib.
when I do ldd on my library address2lineutil.so
...ANSWER
Answered 2017-Sep-08 at 03:34How do I make the function call to be called in libbfd-2.29.so.
You don't. UNIX shared libraries don't work the same way as Windows DLLs do, and in particular, your libaddress2lineutil.so
doesn't know that it's supposed to call into libbfd-2.29
and not into libbfd-2.22-system
. It will call into whatever library first provides the symbol it is trying to call.
You must arrange for the application to link against a single copy of libbfd.
Probably the easiest way to achieve that is not to link the test app against libbfd-2.22-system.so
, and link it against libbfd-2.29.so
instead.
