#4065 Build failure under Solaris with --enable-dtrace

obsolete: 8.5.3

Current CVS Tcl fails to build under Solaris Express. It dies with:

stlib_ld () { /usr/ccs/bin/ld -r -o ${1%.a}.o "${@:2}" && /usr/ccs/bin/ar cr ${1} ${1%.a}.o ; } && stlib_ld libtclstub8.5.a tclStubLib.o ; /usr/ccs/bin/ranlib libtclstub8.5.a
sh: bad substitution
*** Error code 1
make: Fatal error: Command failed for target `libtclstub8.5.a'

That's because of setting shell to sh and using bash syntax. Happens under both make and gmake. Attached simple patch fixes the issue for me.

    urk, good catch, thanks!
    (note this only occurs with --enable-dtrace)
    I don't think your fix is feasible in general however, we cannot assume bash is available on all platforms where tcl compiles...
    I'd welcome other ideas on how we can define a STLIB_LD that has the desired effect (linking all object files into an intermediate object file and ar'ing that) and takes the same arguments as 'ar cr'... (besides relying on a separate script file)

    But we can safely assume bash is available on platforms where DTrace is available. At least for Solaris this is Solaris 10, which has it by default. And I suppose OSX isn't that different? Then we can just change the SHELL variable on seeing --enable-dtrace and everyone's happy.

    the stlib_ld hack is actually not needed on OSX, so only Solaris is concerned (and maybe FreeBSD once their dtrace support is finished)...

    I agree that changing the Makefile.in to have e.g. SHELL = @MAKE_SHELL@ and setting up MAKE_SHELL in configure.in will work (i.e. to /bin/sh by default and to /bin/bash on Solaris with DTrace).

    As I was never that happy with my stlib_ld() shell function solution to the STLIB_LD issue, I'd like to try to find a better solution first, if unsuccessful I will make the above change.

    I can't even begin compiling -- the first thing is does is trying to generated tclDTrace.h -- and that fails:

    kot, please do not add new bugreports to unrelated bugs (and esp. not to several), please open a new issue. In any case it looks like you dtrace is too old to support USDT probes, not much we can do about that, your only option is likely to be to get a newer version of solaris.

    did not find a better way, so fixed this as discussed by forcing the Makefile shell to bash on a Solaris DTrace-enabled build.
