1.4.0 build on Centos 7: speech-dispatcher not found

[F3nryll]

Hi,

I am on Centos 7.9 and I am trying to build version 1.4.0.0. I am going iteratively, fixing one by one cmake errors. I am stuck since some times now on this one below "speech-dispatcher not found".

I thought installing both

• speech-dispatcher-0.7.1-15.el7.x86_64.rpm
• speech-dispatcher-devel-0.7.1-15.el7.x86_64.rpm

would fix it but it didn't.. does it come from another lib like qtspeech ? In the worst case, can I build without it ?

Thanks!

I assume that the speech dispatcher of your distribution ships without cmake support and thus it is not being found. You could write your own cmake scripts or search for ones on the web to fix that.

Alternatively you could install the qtspeech package and then use -Dqtspeech=ON (https://github.com/mumble-voip/mumble/blob/master/docs/dev/build-instructions/cmake_options.md#qtspeech) when running cmake or if you don't want TTS enabled anyhow, you could also just use -Dspeechd=OFF (https://github.com/mumble-voip/mumble/blob/master/docs/dev/build-instructions/cmake_options.md#speechd).

Thank you so much for that quick and very actionnable answer!

Hi,

I finally realized that I need only murmur, so "cmake -Dclient=OFF .." solved more or less all cmake issues.
My next problem is on the "make", with thar error on "‘make_unique’ is not a member of ‘std’" -> I tried several things, replaced it by "csCrypt = std::unique_ptr< CryptStateOCB2 >();", which compiles, but then murmur is crashing at first login attempt. As apparently this could depend of the C++ version, I spend some times to install gcc 10.2.0, but I still have that "std" error.
Any clues would be more than welcome!

So after removing the old gcc, now cmake uses 10.2.0, thanks !

But now, I have another one..

Uninstall the old C headers.

[F3nryll]

First, thank you for taking the time to answer me, even during the we, that's very appreciated :)

Now if you could elaborate a bit on the "old C headers" to uninstall, I am not in my area of expertise..

[davidebeatrici]

I think the package's name begins with glibc-headers.

[Krzmbrzl]

Note that you don't (necessarily) have to uninstall the old compiler. You can tell cmake which compiler to use: https://stackoverflow.com/a/45934279/3907364
