silly question

duilio foschi
I am have FPC v. 2.6.2 installed on linux/ubuntu server A.

I am sure I did some change to zeos library in server A, but I cannot
remember details.

I'd like to have the same version of FPC installed on a new
linux/ubuntu server B.

I found that  FPC v. 3.0.2 was already installed on server B.

Using my poor skills in linux, I took the following steps:

1. deleted directory /usr/lib/fpc/3.0.2 of server B
2. copied directory /usr/lib/fpc/2.6.2 of server A into server B (used scp)

Now a few strange things happen:

a. if I try to run fpc from - say - /usr/lib/cgi-bin , I get the message
Error: ppcx64 can't be executed, error message: Failed to execute
"ppcx64", error code: 127

b. if I try to run fpc from /usr/lib/fpc/2.6.2, a lot of Zeos lib
units are compiled EVERY TIME. This for sure was not happening before
(see below).

I did something silly, right ?

Any help in order to fix the install ?

Thank you

Peppe

That was not necessary.
You can perfectly have 2 versions of FPC co-existing.

Did you correct the symlink /usr/bin/ppcx64 ? it should point to
/usr/lib/fpc/2.6.2/ppcx64

Ill-advised, perhaps.

The above should help you to get things compiling again.

About recompilation of zeos units; 2.6.2 may work differently to 3.0.2
regarding circular units which causes a recompile. Or the zeeos units in
your search path are the old ones.

Michael.

Re: silly question

duilio foschi-2
I got stuck with the symlinks.

The level of indirection is rather complex.

Finally I

1. reinstalled v. 2.6.2 from scratch
2. copied directory zeosdbo from server A to server B
3. copied file /etc/fpc.cfg from server A to server B

now (finally!) everything works as expected.

Thank you

Peppe
