Hello,
SQLite 3.21 autoconf (sqlite-autoconf-3210000.zip) compiles and runs
successfully on z/OS 2.2 with few minor modifications which I would like
the developers to consider for integration into the code base.
Namely:
1 - In sqlite3.c, in the code section coming from tokenize.c, the EBCDIC
version of the aiClass[] array defines codepoint 0x15 as class '27'
(CC_ILLEGAL). In EBCDIC (both codepages 037 and 1047, the most common
ones) 0x15 is actually NL (newline) and should be defined as class '7'
CC_SPACE to allow the tokenizer to properly manage multi-line statements.
There are minor issues in the Makefile generated by ./configure:
2 - The ./configure process wrongly detects the presence of the posix
fallocate function, which is not actually available ("checking for
posix_fallocate... yes"), and sets -DHAVE_POSIX_FALLOCATE=1. It should
be -DHAVE_POSIX_FALLOCATE=0. I don't know why this happens as I was not
able to understand what the check does. I will be happy to help
debugging it if guided.
3- In order to successfully compile sqlite3, the C compiler command
(CC=..) should be changed from cc to xlc; the CFLAGS option should be
set to "CFLAGS = -g -qFLOAT=IEEE -qstrict -qdll" and
"-D_XOPEN_SOURCE=600" should be added to the current DEFS.
If needed I have a diff generated pach for 1) and another one for 2) 3)
to make the required changes better understandable.
With these changes the process to build sqlite is as simple as:
1- Upload a non compressed tarball of the autoconf version of SQLite to
a file in your OMVS environment (let say the file is called
sqlite-autoconf-3210000.tar)
From your OMVS shell issue the following commands
2- pax -ofrom=iso8859-1,to=ibm-1047 -rf sqlite-autoconf-3210000.tar (the
"to" codepage in the pax command must be set to your actual EBCDIC codepage)
3- ./configure --enable-dynamic-extension (I need this option myself but
of course it is not mandatory)
4- for the time being manually apply the changes described above
5- make
Et voilĂ .
At the moment I am testing with the sqlite3 cli, and I can perform
normal operations and load and use dynamic extensions.
I will keep testing and I will report other issues if any.
Hope this helps,
mario
