Build fails because of missing pcre2-10.32

bcapptain commented 5 years ago

Fix: Extract pcre2-10.32.tar.gz to src/external.

Get it here: https://ftp.pcre.org/pub/pcre/pcre2-10.32.tar.gz

ddpbsd commented 5 years ago

Thanks. We haven't really updated the documentation past 3.2 yet. I'm hoping we can add an option to use a system installed pcre2 as well, but I haven't looked into it yet. EDIT: Looks like there is a PCRE2_SYSTEM option already. Nice

vitorhmcorreia commented 5 years ago

Had this issue too, thanks for the workaround.

d4t4king commented 5 years ago

Tried

export PCRE2_SYSTEM=yes
sudo ./install.sh

Still no joy. Did I miss something?

untarring the tarball from the link in the first post to .../src/external works.

ddpbsd commented 5 years ago

@d4t4king Was there any output that might help track down the issue? What OS/distro are you trying this on? Were the PCRE2 packages installed? Are there dev/devel packages that need to be installed?

aquerubin commented 5 years ago

sudo PCRE2_SYSTEM=yes ./install.sh

seems to work on some systems

I don't have a clear recollection of anything useful. I will try to replicate and note the details this time.

d4t4king commented 5 years ago

OK, a little more details. This is on Ubuntu 18.04.

I removed the local git repo and recloned from github. cd into the local directory and ran sudo ./install.sh. ossec-hids is already installed, so I opted to update it. This is the error:

ddpbsd commented 5 years ago

@d4t4king It looks like you're not using PCRE2_SYSTEM=y (and have the appropriate package installed), and you didn't download the pcre2 source.

wget https://ftp.pcre.org/pub/pcre/pcre2-10.32.tar.gz
tar xzf pcre2-10.32.tar.gz -C src/external

wget https://ftp.pcre.org/pub/pcre/pcre2-10.32.tar.gz
tar xzf pcre2-10.32.tar.gz -C src/external

So ALL of the above is required? o_O The last bit worked for me before without exporting PCRE2_SYSTEM. pcre2 was installed, but not the -dev package.

I don't have access to that system at the moment. I will test it again exporting the environment variable, but pretty sure that didn't work before.

aquerubin commented 5 years ago

You may need to install libpcre3-dev as well.

d4t4king commented 5 years ago

You may need to install libpcre3-dev as well.

libpcre3-dev is the "old" (as in NOT PCRE2) PCRE library. It's a little counter-intuitive. I'll give it a try.

Understood but you did have both listed in your package list so it might matter. This worked for me on an Ubuntu and a Mint system. For some reason the Ubuntu system also required a manual ldconfig after installing libpcre2.

ddpbsd commented 5 years ago

I must have typo'd that, sorry. It's not PCRE_SYSTEM=y, it's PCRE2_SYSTEM=y

d4t4king commented 5 years ago

ok, it worked with the legacy pcre library (libpcre3-dev) installed, but then failed zlib. installing the zlib -dev library fixed that and it installed fine.

So maybe PCRE2_SYSTEM should be changed to PCRE_SYSTEM since it seems to look for the legacy PCRE lib with this option? Minor detail....

Other modern install scripts install the necessary packages, why not do that here?

ddpbsd commented 5 years ago

I'm able to build on OpenBSD without the pcre package installed. On an Ubuntu 18.04 container, I don't have libpcre3-dev installed, and it compiled just fine.

I see you built using make directly in the source. Try using install.sh. Maybe the requirement is imposed by the script and not the actual source.

I did a local installation via install.sh. Worked fine.

janiko71 commented 5 years ago

Hi all, I tried an install on a armhf server today, with the master branch, and I got the libpcre error seen here. I tried to install all libpcre packages I could find with no (good) result. I didn't try to change the Makefile or anything (PCRE/PCRE2_SYSTEM parameter). After that, I dropped to 3.2.0 branch (after deleting the install directory). Then I got an error about zlib, then I installed zlib1g-dev on my system, and the compilation worked...

justinludwig commented 5 years ago

Thanks to this thread, I was able to update from ossec 2.9.x to 3.3.0 on ubuntu 18.04 -- the two new packages I had to install were libpcre2-dev and zlib1g-dev. Specifically, this is what worked for me:

sudo apt install libpcre2-dev zlib1g-dev
sudo PCRE2_SYSTEM=yes ./install.sh

jubois commented 5 years ago

Hi everybody! You should extract pcre2-10.32.tar.gz to src/external for better performances. This way, installation is working and PCRE2 is compiled using jit, and is way more faster...

Note that PCRE2 is used for all regex, even for the default rules...

Nono-m0le commented 5 years ago

On a fresh Ubuntu Server 18.04.2 , installing the current stable (3.3.0) work with the @justinludwig solution below (https://github.com/ossec/ossec-hids/issues/1663#issuecomment-487341751)

I'm not that great at make syntax, but it looks like the environment variable isn't being pulled in for some reason.

So I ran into this exact same issue but had a different solution. I'm incredibly new to Ubuntu, my boss wanted me to demo OSSEC as a SIEMs solution. I don't know about modifying a config file or anything like that but the OSSEC installer is looking for PCRE2 here: --prefix=/home/charlie/Downloads/ossec-hids/src/external/pcre2-10.32//install \

It fails cause that directory doesn't exist. So I went into the ossec-hids-3.3.0, mkdir src, mkdir external, went into the external folder, downloaded and extracted pcre2-10.32.tar.gz there and was able to successfully run through the installation without error.

Still having the same issue with pcr2 not available in the external directory ... Last version of ossec 3.3.0 on Debian 9.6.0

ddpbsd commented 5 years ago

Sorry @theoooooo I don’t see your previous report of an issue. What problem are you having exactly?

Theoooooo commented 5 years ago

@ddpbsd I had to add manually the missing folder to be able to complete the installation as described above :

Fix: Extract pcre2-10.32.tar.gz to src/external.

Get it here: https://ftp.pcre.org/pub/pcre/pcre2-10.32.tar.gz

ddpbsd commented 5 years ago

So it’s working as expected. I have a pull request for defaulting to the system pcre2. I can’t remember the status of it off hand, but it should help with the confusion. Or everyone will report that they had to install the package to get it to work. We’ll see what happens.

ghost commented 5 years ago

I never managed to get the installer working properly. I ended up adding the repo which worked fine.

wget -q -O - https://updates.atomicorp.com/installers/atomic | sudo bash apt update;apt install ossec-hids-server -y or yum install ossec-hids-server -y

I successfully updated my build from 3.1 to 3.3 with this method

Please note that doing this implies lower performances as pcre2 is NOT compiled using JIT. For better performances:

wget https://ftp.pcre.org/pub/pcre/pcre2-10.32.tar.gz tar xzf pcre2-10.32.tar.gz -C src/external ./install.sh

kristianpaul commented 4 years ago

Is there any license issue that stop us on distributing pcre inside src/external the same way lua is there?

ddpbsd commented 4 years ago

@kristianpaul Not that I'm aware of (but I haven't really checked either). Just trying to cut down on the number of external projects we bundle.

kristianpaul commented 4 years ago

IMHO this should be bundled, either if we point the docs on how to fetch it/un tar it and/or make that process part of an script.. there is a uncertainty of that file might not be available at some point (unless lives in github perhaps, need to check that last one..)

ddpbsd commented 4 years ago

@kristianpaul I think the default right now is to use pcre2 from the system (installed through the OS's package manager). As long as you have the dependency installed, it shouldn't cause any issues. But feel free to submit a pull request to bundle it. Maybe there's more demand for it than I realize.

kristianpaul commented 4 years ago

Well more than demand, i just came across this issue because was installing OSSEC 3.3 few minutes ago and it complained about pcre2.. Will consider sending the PR for sure

IMHA, the good way to do it is to bundle pcre into scr/external. This way, the lib is compiled using JIT, and performances are WAY better.

For macOS, I could not use the pcre2 library downloaded following the instructions here. Add to install the library through brew:

brew install pcre2

After which I used the newly installed system pcre2:

sudo PCRE2_SYSTEM=yes ZLIB_SYSTEM=no ./install.sh

On Centos 7, I had to install pcre2:

sudo yum install pcre2 pcre2-devel sudo PCRE2_SYSTEM=y ./install.sh

Thanks!

On Ubuntu 18 This worked

sudo apt install libpcre2-dev zlib1g-dev sudo PCRE2_SYSTEM=yes ./install.sh

On CentOS 7, I had download the pcre2 and untar to src/external dir. Not working.

$ cd ossec-hids-*/src

$ wget https://ftp.pcre.org/pub/pcre/pcre2-10.32.tar.gz

$ tar xzf pcre2-10.32.tar.gz -C ossec-hids-*/src/external

And I tried system's pcre2, not woring. Same error info.

PCRE2_SYSTEM=yes ./install.sh

Hers is the error infomation.

sudo PCRE2_SYSTEM=no ./install.sh
works.

The above poster is correct, if using the locally-built pcre2, you have to explicitly set PCRE2_SYSTEM=no, because yes is now the default since 1dba4e8698b1d262d3cafce77dfc808b2f19d1d9 . So it will continue to error out if you don't have a system PCRE2.

Hi, I tried out stuff that u guys mentioned above:

I have Extract pcre2-10.32.tar.gz to src/external. sudo PCRE2_SYSTEM=no ./install.sh sudo PCRE2_SYSTEM=yes ./install.sh

I don't have the PCRE2 problem anymore but I'm still facing this issue: Capture1

I do not understand the error. Clearly, I have the installation file and I can run the script. My machine is running Ubuntu 18.04.4 LTS The OSSEC file that I downloaded is from https://github.com/ossec/ossec-hids/archive/3.6.0.tar.gz

Nevermind, I solved it by installing the following packages: sudo apt-get install build-essential sudo apt install libssl1.0-dev apt install libz-dev libssl-dev libpcre2-dev libevent-dev

ossec / ossec-hids

Build fails because of missing pcre2-10.32 #1663
