Hi,

Compiling Bro 2.4 with CAF 0.13.2 works fine. However, after updating to CAF 0.14.0, Bro fails to compile with error message:

Scanning dependencies of target broker  
make[3]: Leaving directory `/usr/src/setup/bro/bro-2.4/build' make[3]: Entering directory `/usr/src/setup/bro/bro-2.4/build’

From the build, I can see this:

– Found Libcaf: /usr/local/lib/libcaf\_core.so;/usr/local/lib/libcaf\_io.so  
– Found CAF version: 0.14.0

The path of the file “abstract\_uniform\_type\_info.hpp” in CAF 0.14 is:

ls -l /usr/local/include/caf/abstract\_uniform\_type\_info.hpp  
-rw-r–r-- 1 root root 3600 Jul 10 05:15 /usr/local/include/caf/abstract\_uniform\_type\_info.hpp

However, the path of the same file in CAF 0.13.2 is:

/usr/local/include/caf/detail/abstract\_uniform\_type\_info.hpp

The directory “detail” is dropped in CAF 0.14.0

I tried configuring Bro again, this time adding --with-libcaf, but the same error persisted. Since the paths seemed different, I made changes to Bro code to look at the new path. This did not work. I also tried moving “abstract\_uniform\_type\_info.hpp” inside “detail” to mimic CAF 0.13.2, and that also did not work. In both cases 1) code change, and 2) directory change, I ended up with the same error(s):

and GCC version is

I thought of checking with the list if anyone faced the same issue, or whether I should contact the Actor Framework maintainers.

Thanks.

As of CAF 0.14, caf::detail::abstract\_uniform\_type\_info is no longer  
considered an implementation detail and has therefore been hoisted to  
the parent namespace.

I've pushed the necessary fixes to the branch topic/caf-0.14-fix (which  
also get rid of the deprecated sb\_actor warnings and a compile error on  
OSX). Please give it a shot to see whether it works for you now.

Jon, if that looks fine to you, feel free to merge.

Thank you Matthias for quickly jumping into this.

Is the branch pushed already? I am not able to locate it yet. I will wait some time and try again and will update with my results.

Thanks again.

Yes, I pushed it immediately:

Let me know how it works.

Ah, it is under Bro's repo; I was looking in the Actor Framework repo.  
Thanks for pointing this out.

> Let me know how it works.

Bro compiled successfully with the fix you provided. Here is what I did for  
sanity checking and as a reference if somebody else faces the same issue.

1. Cloned the Actor Frame (0.14.0) again and deleted the old one (0.13.2)

2. Cloned Broker and merged the caf-0.14-fix branch:

&nbsp;&nbsp;&nbsp;git clone [GitHub - bro/broker: Bro's Messaging Library](https://github.com/bro/broker.git)  
&nbsp;&nbsp;&nbsp;git pull origin topic/caf-0.14-fix

3. Copied the contents of the just cloned/merged broker fix branch into  
Bro's broker directory (this and step 2 could have been done directly using  
git, but not sure how 🙂 ):

&nbsp;&nbsp;&nbsp;&nbsp;cp -r broker/\* bro-2.4/aux/broker/

4. Compile Bro successfully.

&nbsp;&nbsp;&nbsp;&nbsp;ldd /usr/local/bro/bon/bro

&nbsp;&nbsp;&nbsp;...  
&nbsp;&nbsp;&nbsp;libcaf\_io.so.0.14.0 =\> /usr/local/lib/libcaf\_io.so.0.14.0  
(0x00007fcccc6fb000)  
&nbsp;&nbsp;&nbsp;...

Good to know, we'll integrate the fix then.

Once we've updated the submodules in the Bro repo, this will no longer  
be necessary. (Instead of copying, another ad-hoc fix would simply  
involve changing the SHA of the broker submodule and then update your  
submodules again.)
