Several versions of FPC
lazarus / 1-Linux

I trying to have stable (2.6.4) and trunk (3.1.1) of FPC at the same
time. First of all I was confused by running ./fpc from installation
path where fpc was compiling: ./fpc calls ppcx64 as system default,
not as part of the trunk binary. It was distressingly when I call
./fpc from trunk and have something like `Free Pascal Compiler version
2.6.4` instead of `3.1.1` So I copy `ppcx64` from
`~/dev/fpc/foo/lib/fpc/3.1.1/ppcx64` to the trunk `bin` after building
FPC from sources and it is like to works properly after that. Is it
right way or there is something more 'official'?
PS: And is there some chance to have `.deb` packages for
betas/snapshots at the FPC FTP server?

Thanks.

Not default, but one can select the ppc* using -V and -P options.
Requires to only rename one of the ppcx64.

See last bits of this paragraph of the buildfaq

so there is no common decision like:

sudo apt-get install subversion
cd ~
mkdir d
cd d
svn co http://svn.freepascal.org/svn/fpc/trunk fpc
cd fpc
make clean all install INSTALL_PREFIX=~/d/fpc/foo
cd ~/d/fpc/foo/bin
./fpc

And get 'Free Pascal Compiler version 3.1.1 [2015/11/02] for x86_64'

?

No. Install does only install into a prefix. It has no record of older
installations and in general doesn't do anything that can be
considered "configuration".

I skipped configuration because it is looks like for win OSes with
single path instead of *nix with usr/bin, usr/share ~.config etc. I
told about fpcmkcfg utility.

I'm sure you know what you are doing

I am sure too   But as Windows user I was used to 'out-of-box'
software and when I killed the last Win entity   at my home and trying
to use FPC at Linux   then I encountered some questions...
