# [Solana]Anchor problem with openssl in CentOS 9 By [Kevin](https://paragraph.com/@kevin-45) · 2022-12-05 --- What is the problem ------------------- When to execute `anchor test`, the terminal would be shown somethings like `libssl.so.1.1: cannot open shared object file: No such file or directory`, and the fact is your openssl has already been installed, so why is that? * * * Why dose the issue come ----------------------- Before we start, you can have a check with `openssl version` in your terminal. Yes, as you can see, in CentOS 9, the default openssl version is 3.0+, this is the reason why you got the error with `libssl.so.1.1`, because you really do not have openssl 1.1.0+, but 3.0+ instead, which is not suitable. * * * How to fix it ------------- We quickly start to fix it by installing openssl 1.1.0+, and a good news is you don’t really have to uninstall the 3.0+ version, according to [here](https://unix.stackexchange.com/a/723039). So let’s just simply install it by the source package following the steps. ### Firstly, downloading the source code of openssl 1.1.0+ Downloading source code by using [this official link](https://www.openssl.org/source/), as I cannot know what time you see this article and whether there is a update for openssl 1.1.0+, so just scrolling down and find the place as the picture shows bellow, then right click the file name and copy address link. ![openssl 1.1.0+](https://storage.googleapis.com/papyrus_images/7c6d9a16ca314f3d00998a950a53239d6c46c725f5922ae83c2da2c6832c56cd.png) openssl 1.1.0+ > Please make sure you copy the link of openssl-1.1.xxxx.tar.gz, not the other versions. Then go back to your terminal, using `wget [paste the copied link here withouth square brackets]`, for me is like bellow. ![wget openssl source package](https://storage.googleapis.com/papyrus_images/7901654a8b273453029b56c1ca6a683d2529c9717bdf6f5fa5d6663b81871939.png) wget openssl source package ### Secondly, installing openssl from this source package > Installing tools and dependencies before for after usage. `sudo dnf update -y #this will make sure your local software list is updated to latest version.` `sudo dnf group install ‘Development Tools‘ -y #install development tools which includes compile tools.` `sudo dnf install perl-core zlib-devel -y #and these two things too.` > OK, now you have the compile tools for OpenSSL, let’s go and install it! `tar -xzvf opensslxxxx.tar.gz #the file’s name is as what you have downloaded from official website.` `cd opensslxxxx #go into the folder that extracted right above, the name should be your openssl source file erased .tar.gz.` `./config --prefix=/opt/openssl --openssldir=/usr/local/ssl shared zlib` `sudo make && make install #just wait, this will be finished soon.(or not lol)` ### Final step, \[must do\], configure all things `sudo mv /bin/openssl /bin/openssl.backup #we’ll use new 1.1.0+ one to instead old 3.0+ one, so just move it as a backup.` `sudo vi /etc/profile.d/openssl.sh #openning this file for export path of our new openssl in $PATH.` #paste this all into the opening edit window. OPENSSL_PATH=”/usr/local/ssl/bin” export OPENSSL_PATH PATH=$PATH:$OPENSSL_PATH export PATH `:wq #write and quit the file.` `sudo chmod +x /etc/profile.d/openssl.sh #make this file can be executed.` `source /etc/profile.d/openssl.sh #export our new openssl execute path into $PATH.` `echo $PATH #if you like, you can have a check with this, should be at the end of the string.` `sudo vi /etc/ld.so.conf.d/openssl-1.1.1i.conf #this is for shared libs.` #paste this into the window opened for openssl-1.1.1i.conf /usr/local/ssl/lib `:wq #using it to quit file edit mode.` `sudo ldconfig -v #to refresh dynamic link.` ### Have a check with our new openssl 1.1.0+ by bellow two commands! `which openssl` `openssl version` > Yours should be similar(according to our official version may not exactly be the same) with mine like bellow. ![Hooray! The result of openssl is fine! ](https://storage.googleapis.com/papyrus_images/0f62369fe157612fc7672c7b3069c0f5e53dd315041a76b2fd387fa5da3f5aa1.png) Hooray! The result of openssl is fine! ### Now, you can have a check with the command \[anchor test\] in your project again. 😊Surprise~ * * * Plus ---- > I heard that there is a way to deal with the problem by using lsb packages. > > However, unfortunately, I’m not sure whether it should be true, due to Red Hat Team doesn’t support redhat-lsb/redhat-lsb-core in CentOS 9 until now as [this link from bugzilla](https://bugzilla.redhat.com/show_bug.cgi?id=2012924#c4). > > If you have interest in, you can have a check about [this one](https://bugzilla.redhat.com/show_bug.cgi?id=2088203#c3) I found, but just not working for me.
