Bug: ubuntu 18.04 amber intstallation

[zenny]

HI,

In ubuntu 18.04, amberframework fails to build with the openssl issue:

~/amber-stable# make install
Building amber in /root/amber-stable/bin/amber

But builds fine in ubuntu 16.04.

@docelic Are you using ubuntu 18.04, Did you have a similar issue?

@zenny I think amber guides are a bit outdated, so the dependencies may be changed, if you found a fix for this, please feel free to contribute with Guides/Installation

We have a nice Edit on Github button now 😉

[docelic]

@faustinoaq never seen that issue myself.

[faustinoaq]

@docelic Maybe we should update dependencies in amber guide, see: Installation for Debian & Ubuntu

@zenny @faustinoaq I had this same issue.

It was resolved following the advice of installing dependencies with apt buildep nginx . Some of these have the missing files required for compiling.

[faustinoaq]

@Rojo Oh, nice 👍 , maybe we should update Installation guide or add a new section on Amber troubleshooting, WDYT?

[Rojo]

@faustinoaq It would be nice to identify which of those packages are the required ones and add them to the guide, 'cause the build dependencies for nginx are a lot. But, since right now we only have this workaround, I think a troubleshooting note at the installation instructions, that points to this particular error, would do.

I have tried to install the nginx build-deps using ubuntu 18.04 and it doesn't worked for me.

OS: Ubuntu 18.04

The same error can be found using the latest crystallang docker image.

[faustinoaq]

@lcdss Yeah, see #826

I believe this has been addressed. If not, please re-open.
