tcl cannot build 64bit.

tcl cannot build 64bit.

[Manoj Iyer]

When I build GDB 6.1 CVS version as a 64bit binary, the tclsh fails to
build. The linker complains "skipping incompatible
/home/manjo/project/build_scripts/src/tcl/unix/libtcl8.4.a when searching
for -ltcl8.4" even though libtcl8.4.a is availale in that directory.

When I force it to link with the archive I get a bunch of  undefined
reference to ".symbol" as follows: ( I am only pasting a few). And they
look like glibc symbols...

/home/manjo/project/build_scripts/src/tcl/unix/libtcl8.4.a(tclIOGT.o)(.text+0x1b18):

Any suggestions??

GDB or expect?  GDB doesn't need tcl.  The expect in the repository is 
sufficiently out-of-date to be getting dangerous :-(  I'd just use "make 
all-gdb".

That is something I wondred... why build expect in the same package as
gdb??

Actually it does, unless you configure with --disable-gdbtk.

Er, no, here's my link line:

/usr/pkg/bin/ccache gcc -g -O        -o gdbtui tui-main.o libgdb.a 
../sim/ppc/libsim.a ../bfd/libbfd.a ../readline/libreadline.a 
../opcodes/libopcodes.a ./../intl/libintl.a ../libiberty/libiberty.a 
   -lm -lcurses     ../libiberty/libiberty.a

(ok ignore me using ccache :-) you probably checked out the non FSF 
insight :-(

Ok, it's not gdb itself, but there is the gdbtk subdirectory.

Sounds like you did the dreaded `cvs update -d`.  Just remove the 
directory, it isn't needed.

Andrew

Re: tcl cannot build 64bit.

[Manoj Iyer]

Andrew,

Well the problem is in the Makefile.in file in the tcl/unix directory.

tclsh: ${TCLSH_OBJS} ${TCL_LIB_FILE}
        ${CC} ${LDFLAGS} ${TCLSH_OBJS} @TCL_BUILD_LIB_SPEC@ ${LIBS} \
                ${CC_SEARCH_FLAGS} -o tclsh

add ${CFLAGS} to the above fixes the unresolved symbols problem, and tclsh
builds like a charm :-) so the code should look like this...

src/tcl/unix/Makefile.in:479

tclsh: ${TCLSH_OBJS} ${TCL_LIB_FILE}
        ${CC} ${CFLAGS} ${LDFLAGS} ${TCLSH_OBJS} @TCL_BUILD_LIB_SPEC@
	${LIBS} ${CC_SEARCH_FLAGS} -o tclsh

since I am building using CFLAGS="$CFLAGS -m64", the -m64 is not passed to
this step, and the linker tries to link 32bit & 64bit binaries to gether
and the build fails.

Sorry I dont have a FSF approval currently to submit this as a patch. But
I will be getting one sometime this month. I can send you the patch then
or you can patch this for me :-)

Thanks
Manoj Iyer

It's still there, with plenty of contents, including all branches.  If
it's not needed it should be removed from CVS.

You should use CC="$CC -m64" instead.

The src directory is used for a number of different packages, not just
gdb.

If you 'cvs co gdb' and then avoid using 'cvs update -d' at top level,
you should be OK.

Not using -d is not an option.  And the gdbtk directory even exists on the
branch.

If you don't want to end up building Insight, update by using "checkout
gdb".  Unfortunately, --disable-gdbtk doesn't fix the top level from
deciding gdb depends on tcl; that could be fixed in configure...

Re: tcl cannot build 64bit.

[Manoj Iyer]

I think I emailed the fix to the problem wrt to building tcl 64bit. All
it requires is a one line fix in Makefile.in.

src/tcl/unix/Makefile.in:479

tclsh: ${TCLSH_OBJS} ${TCL_LIB_FILE}
        ${CC} ${CFLAGS} ${LDFLAGS} ${TCLSH_OBJS} @TCL_BUILD_LIB_SPEC@
        ${LIBS} ${CC_SEARCH_FLAGS} -o tclsh


It is missing the ${CFLAGS} in the cc line.

It shouldn't be needed, since it's a link command, not a compile command.
If you need -m64 for linking you must add it to LDFLAGS.  Or just use
CC="$CC -m64" since it's actually a different compiler after all.

The GNU standards require that CFLAGS be used in every command which
uses CC, including ones which simply link.

Of course, Tcl is not a GNU program.

I am a little confused, I thought -m64 is a compiler option. Specifying
it along with LDFLAGS might fix this problem, but is that the correct?
