Re: [Seed7-users] Seed7 installation problems

Hi Anders,

>From what I can see your manual build of Seed7 (without installer) works now.
>From your previous mail I assume that your PostgreSQL 13 is installed in:

  C:/Program Files/PostgreSQL/13

I installed PostgreSQL on my windows computer and there it is at the same place.
When I downloaded PostgreSQL I saw that there is just a 64-bit version of it.
On a 64-bit Windows computer 64-bit programs are usually installed in:

  C:/Program Files

and 32-bit programs are usually installed in

  C:/Program Files (x86)

My older PostgreSQL 10 is 32-bit and it is installed in:

  C:/Program Files (x86)/PostgreSQL/10

In your version.h file the line:

  #define POINTER_SIZE 32

shows that your gcc is a 32-bit compiler. This is the reason why chkccomp.c
does not find your PostgreSQL 13. This is on purpose as using a 64-bit dll
from a 32-bit program will not work.

The Seed7 installer seed7_05_20191117_win.exe uses a 32-bit gcc.
I decided for 32-bit such that it works on 32-bit and 64-bit Windows versions.
So you cannot use the gcc from the Seed7 installer.

But it seems that you already did not use the installer.
That means: Your locally installed MingGW gcc is 32-bit.

You need to install a 64-bit MinGW (with a 64-bit gcc).
With a 64-bit gcc you are also able to connect to PostgreSQL 13.

On my Windows computer PostgreSQL 13 was recognized by chkccomp.c.
I was able to come past this DATABASE_ERROR:

  Searching for dynamic libraries failed: libpq.dll

It turned out that PostgreSQL 13 needs two more dlls in order to
load libpq.dll:

  libcrypto-1_1-x64.dll
  libssl-1_1-x64.dll

I have changed chkccomp.c and sql_post.c to search for these
two dlls also. The definitions regarding PostgreSQL in version.h are:

#define POSTGRESQL_DLL "C:\\Program Files/PostgreSQL/13/lib/libpq.dll", "C:\\Program Files/PostgreSQL/13/bin/libpq.dll", "libpq.dll",
#define LIBINTL_DLL "C:\\Program Files/PostgreSQL/13/bin/libintl-8.dll", "libintl.dll", "libintl-8.dll", "libintl-9.dll",
#define LIBEAY32_DLL "libeay32.dll",
#define LIBCRYPTO_DLL "C:\\Program Files/PostgreSQL/13/bin/libcrypto-1_1-x64.dll", "libcrypto-1_1-x64.dll",
#define LIBSSL_DLL "C:\\Program Files/PostgreSQL/13/bin/libssl-1_1-x64.dll", "libssl-1_1-x64.dll",

I have attached the improved files chkccomp.c and sql_post.c.

As soon as you have installed a 64-bit gcc you can replace
chkccomp.c and sql_post.c with the attached files and try to
build again. Don't forget to do a

  make clean

before you start a new attempt to compile Seed7:

  make depend
  make

I hope that helps.
