Compiling SQLite Tcl bindings for 32-bit linux on 64-bit linux

[Gerry Snyder]

This afternoon I compiled the SQLite 3.8 Tcl bindings for windows and
64-bit linux, and thought I would try a 32-bit compile on the linux box
too. I already had the gcc multilib packages installed.

First I did:

./configure --host=i686-linux-gnu "CFLAGS=-m32" "CXXFLAGS=-m32"
"LDFLAGS=-m32"

(all on one line). That seemed to run okay, but

make

failed with:

gcc -shared -m32 -pipe -O2 -fomit-frame-pointer -Wall -fPIC -m32
-Wl,--export-dynamic -o libsqlite3.8.0.so tclsqlite3.o -lpthread
-L/home/gsnyder/ActiveTcl-8.6/lib -ltclstub8.6

/usr/bin/ld: skipping incompatible
/home/gsnyder/ActiveTcl-8.6/lib/libtclstub8.6.a when searching for
-ltclstub8.6

/usr/bin/ld: cannot find -ltclstub8.6

Is it just that I need a 32-bit Tcl present? Or did I get the configure
options wrong? Or any other guesses?

Thank you,

Gerry

Yes, the error means it is trying to link against a 64bit Tcl lib, which
cannot work, of course. You need to install Tcl frst and then set the
configure flags accordingly such that sqlite finds the 32bit-Tcl
(pesumably --with-tcl=/path/to/32bit/Tcl, check with --help)

BTW, when you have ActiveTcl, you can just pull in sqlite via teacup.
And compiling stuff can be automated via kbs.tcl

Maybee another hint:

Please take care, that the 64 bit libraries go into /usr/lib64 and any 32bit or independent stuff in /usr/lib.

Here are hints for CentOS:

Thank you Christian and Harald for your replies.

I had had the thought that if the stubs table was all that was needed, a
single Tcl installation might suffice. Now that it has been pointed out
to me, it is not surprising that stubs can work across versions, but not
across platforms (and especially across platforms with different
pointer/word sizes).

Thanks again,

Gerry
