Re: [Seed7-users] Seed7 installation problems

Hi Anders,

It seems that you have still problems unrelated to Seed7. You wrote:

Seed7 does not have any files that start with _ like _config.h.
So I guess that your extracting tool produces them.
What tool you are using to extract?

> 2. Renamed all the files starting with _

This should never be necessary. You should probably delete the directory
that this extraction tool created and use a better tool to extract
the Seed7 archive. Maybe the tar7.exe commandline tool is useful for you.
See: https://sourceforge.net/projects/seed7/files/bin/
You can put tar7.exe in a directory that is in the search path.
On windows computers I usually have a directory like c:\Users\tm\bin
with the *.exe files of some tools I like. In order to accessable this
directory needs to be added to the PATH environment variable.

> 3. Start cmd-window in admininistrator mode

Compiling Seed7 does not need admininistrator rights. You should just
use a normal cmd-window. Later you need administrator rights to do the
install, but you will be asked for that with a popup window that mentions
setwpath.exe.

Okay.

These settings are wrong and they should not be necessary. Normally
chkccomp.c should know that verson 13 of PostgreSQL exists. Unfortunately
this knowledge is missing in the chkccomp.c of Seed7 version 2021-01-30.
I will sent you an intermediate release which should support verson 13 of
PostgreSQL. Please tell me if that works.

Don't forget to turn you anti-virus program on again later.

The file install_1.txt shows that more files are missing.
These missing include files are mentioned:

  seed7/lib/null_file.s7i
  seed7/lib/comp/config.s7i
  seed7/lib/comp/const.s7i
  seed7/lib/comp/con_act.s7i

Probably your extraction tool added also an _ to the name.
You definitively should use a different tool to extract *.tgz files.

The Seed7 installer uses its own extraction library, so it can avoid the
problems that your extraction tool triggers. The installer uses also its
own make library (see make.s7i) and its own gcc from the directory seed7/gcc,
so it does not depend on mingw32-make and your local installation of gcc.
BTW at: https://sourceforge.net/projects/seed7/files/bin/
you can find make7.exe, which can be used as make tool like mingw32-make.

> Message from the DATABASE_ERROR exception:
> Searching for dynamic libraries failed: C:/Program Files/PostgreSQL/13/lib/libpq.dll

This message is triggered by the fact that libpq.dll depends on two other
dlls: libintl.dll and libeay32.dll
For libpq.dll you specified the absolute path:
C:/Program Files/PostgreSQL/13/lib/libpq.dll
Unfortunately the windows function to load a dll does not look for other
dlls (libintl.dll and libeay32.dll), on which libpq.dll depends,
in the same directory. As a result the attempt to load libpq.dll fails.

I will send you an intermediate release of Seed7, which will contain
fixes in chkccomp.c to solve your problem regarding PostgreSQL.

I have improved chkccomp.c in two areas:
 1. It now knows about PostgreSQL version 13. This means it will look
    into "C:/Program Files/PostgreSQL/13/" to search for include files
    and libraries. Changes in the makefile (chkccomp.h) should be not
    necessary. Please tell me if it works without these changes.
 2. If you define POSTGRESQL_DLL with an absolute path of libpq.dll in
    the makefile (as you did) the program chkccomp.c now computes
    absolute paths for libintl.dll and libeay32.dll (in the same
    directory as libpq.dll).

Please tell me if the intermediate release works.
