mangos zero Can't build on debian 9

[curatio]

Hello,

 

I can't build the newest release of mangos zero on my Debian 9 system.

I get the following error:

On Debian 8.8 I could build the mangos zero client for a couple of weeks.

Is this a global problem on Debian 9 with mangos or just a problem I have?

 

Thanks,

Hello Curatio,

No one is working on this AFAIK. At least, no one tu spport OpenSSL 1.1.0. The workaround is, as Olion mentionned, get the sources of OpenSSL1.0.x and compile them against Debian v9. Or find a repository that provides Openssl 1.0.x on Debian 9.

Hello,

I think this is because of Debian 9, it has other dependencies and it was not analyzed

Thanks for your answer. Is there something I can do to help to fix this problem?

Hello,

Yes, sure ! There's a function at the top that checks the Linux distribution to download the right dependencies (look for lsb_release inside the script), you need to add the right 'switch case' instruction there. Then, have a look to the requested dependencies.

I also see that the build is failing because of OpenSSL, I'm afraid your version would be too recent compared to the expected one from Mangos  For security reasons, it's dangerous to do this but you could downgrade your openssl version to have it working. In fact, I think it's the only missing piece here..

It is a known issue related to OpenSSL progress from 1.0.1 to 1.1.0, see for example this and wiki reference within. The main statement:

Quote

Supporting < 1.1.0 and 1.1.0 at the same time will probably require lots of #ifdef and/or wrapper functions like the OpenSSL wiki page suggests.

Thus, in 1.1.0 declaration from ARC4.h

EVP_CIPHER_CTX m_ctx;

became illegal. This is a task for developers.

A fast practical solution is building the core against OpenSSL 1.0.1, which is the default version for Debian 8.

Are any one working on this problem?

Or should I make a bug report for this?

And is this only a problem for zero or with all mangos releases?

 

Thanks,
