Hello,

There was an old server running Debian 7. That server crashed and had to be
installed. Service provide did not have Debian 7 in install OS list and now
it runs Debian 9. Seemingly, Debian removed 2.5 packages from apt-get type
of install.

I went down the road to compile my own firebird 2.5 on AMD64 from sources.
Downloaded 2.5 sources from web site provided link. I did not know how to
fetch latest sources from git hub.

All was good until I receive below compile error:
make[4]: Entering directory
'/root/Firebird-2.5.8.27089-0/extern/icu/source/layout'

My questions are:
1- Is there easier way to install firebird 2.5 on this Debian 9 Stretch
server?
2- Is there a way to quick fix that compile error? (I have little to no
knowledge of C++)

Any help is appreciated.

Thanks & regards,
