unable to compile the package

[danzmo]

When trying to "Make" the package I continue to get [test] Error

/znc-palaver/znc-palaver-master$ make
Your C++ compiler doesn't properly support regex. Please upgrade to GCC 4.9, Clang or newer.
make: *** [test] Error 1

I have looked at older postings saying to upgrade GCC I have upgraded to GCC 6 and still am not able to get past this step.

gcc --version
gcc-6 (Ubuntu/Linaro 6.3.0-18ubuntu2~14.04) 6.3.0 20170519

Any help with moving on from here would be appreciated.

If you've upgraded the compiler, you may need to run make clean before running make again. Otherwise some caches built from previous GCC version may still be there. Does that allow you to build?

[danzmo]

Thanks, make clean did clear the

Your C++ compiler doesn't properly support regex. Please upgrade to GCC 4.9, Clang or newer.
make: *** [test] Error 1

However, a new error is now produced

/znc-palaver/znc-palaver-master$ make
make: c++: Command not found
make: *** [test-regex] Error 127

@danzmo This should be solved in https://github.com/cocodelabs/znc-palaver/commit/41ca67469b2beb3b7ad0bf0b77de9279fa921814, could you pull these changes and give it another go?

[danzmo]

I've updated the Makefile to what was in 41ca674. I again tried to make and got the following error:

make: g++: Command not found
make: *** [test-regex] Error 127

I've verified that I have g++ and the build-essential is updated and installed. I thought it may have been permission's and I gave the entire directory "znc-palaver-master" 755.

Any other suggestions

Could you please confirm what the following returns in the same shell you are using to build inc-palaver:

$ which g++
$ g++ --version

[danzmo]

The G++ was still using version 4, got it updated to version 6 gcc version 6.3.0 20170519 (Ubuntu/Linaro 6.3.0-18ubuntu2~14.04) I was able to make and compile the .so file and palaver.so is located in the modules directory:

~/.znc/modules$ ll
-rwxrwxr-x 1 danzmo danzmo 3044088 Jan 30 09:55 palaver.so*
-rwxrwxr-x 1 danzmo danzmo 2533824 Jan 16 13:42 push.so*

I tried to loadmod and have produced the following error:

loadmod palaver
<*status> Unable to find modinfo [palaver] [Unable to open module [palaver] [/usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /home/danzmo/.znc/modules/palaver.so)]]

The Lib is available:

lrwxrwxrwx  1 root root       19 Aug 20 13:01 libstdc++.so.6 -> libstdc++.so.6.0.24
-rw-r--r--  1 root root  1114368 Aug 20 13:15 libstdc++.so.6.0.24

This sounds like ZNC was built with a different libstdc++ than the one used for znc-palaver. Could this be the case? I think these will need to match.
