Problem reported by Ralf Wildenhues. Some things to be aware of here: 1) Libtool branch-1-5 aims to be compatible to Autoconf-2.50; also I aim to not add more unnecessary incompatibilities with Autoconf-2.13, as there are users who patch the missing bits to make it compatible with it. 2) Libtool (at least branch-1-5) aims to be compatible to Automake-1.4. 3) Autoconf-2.61b (CVS) still doesn't document AS_EXECUTABLE_P. Do you think the approach below is safe enough? Note I intentionally do not use the _AS_TEST_PREPARE from 2.61: if you use new enough Autoconf, then that is already defined and will be used. Can I assume that AS_EXECUTABLE_P may eventually be made a public Autoconf interface (then we could just do away with our copy of _AS_TEST_PREPARE and AS_EXECUTABLE_P)? Note CVS HEAD Libtool doesn't need this: it uses $as_executable_p only in its version of AC_PROG_SED, which itself is not defined iff already given by Autoconf. OK to apply?

HEAD: document old macro names and undeprecate some
This patch fixes a documentation regression: It adds documentation for the branch-1-5 macro naming scheme to HEAD's manual, listing most of the old macro names as deprecated. Since however some of the old macro names provide functionality not possible with LT_INIT, it also resurrects some macros as non-deprecated. For example, invoking AC_DISABLE_STATIC in a shell conditional works at least partly[1] (and is used quite a bit in real-world packages). AFAICS this is not possible with LT_INIT([disable-static]). Do you think that AC_ENABLE_FAST_INSTALL AM_ENABLE_FAST_INSTALL AC_LIBTOOL_PICMODE should also be documented? They are undocumented in branch-1-5; I left them undocumented for now. Do you think that undeprecating AC_{DISABLE,ENABLE}_{SHARED,STATIC} is a bad idea and that they should be named LT_* instead? FWIW, I am very reluctant to go this route as this would introduce yet another name for the same thing (already 4 names then: AM_X, AC_X, LT_INIT(x) and LT_X then). Several people have reported these issues; I have forgotten who it was, sorry. Speak up and you will be mentioned in the ChangeLog entry. OK to apply? Patch not tested very much yet. Cheers, Ralf [1] There are at least two glitches with putting AC_DISABLE_SHARED et al in a shell conditional: first, I think if you put it in one execution branch, you have to ensure all other branches see one of the *_SHARED macros as well.

HEAD: speed up compile mode
Separating out func_mode_link into a separate file shaves off roughly 30% of the script execution time of `libtool --mode=compile'. But having yet another script hampers portability and simplicity. A nice thing is that it's not necessary. It's sufficient to merely not to have to parse the bulk of the script for this sort of speedup: - Split up the main function to call func_mode_* right after the function definition. - Move all functions (including call) in weighted priority of both expected usage number, average execution time per usage, and size. IOW, func_mode_compile first, func_mode_link and all functions that are only needed by it last. Compared to branch-1-5, HEAD then needs less than half as long for compile mode. Here's an example: Compiling 100 objects of CLN with `libtool -n ... /dev/null'. That is, measuring script overhead only. The sources are C++, the --tag=CXX argument is not passed so func_infer_tag has to do work. branch-1-5: 10.18user 7.39system 0:17.54elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+1737723minor)pagefaults 0swaps HEAD: 8.84user 3.24system 0:12.29elapsed 98%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+740140minor)pagefaults 0swaps HEAD with a separate libtool-link script: 5.55user 2.77system 0:08.32elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+686277minor)pagefaults 0swaps HEAD with the Main split (patch below): 5.63user 2.71system 0:08.32elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+682353minor)pagefaults 0swaps HEAD with patch below plus reordering of functions: 5.29user 2.91system 0:08.05elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+680683minor)pagefaults 0swaps Interestingly, adding --tag=CXX slows down the build by 2%. Using the C compiler instead of the C++ compiler (thus avoiding the need to search for another tag) is 18% faster, where again passing --tag=CC slows down things a bit. (But see the next patch.) OK to apply? This set of patches is a helper for the 2.0 release in that it helps test Libtool more efficiently. ;-) Seriously though, if you see any problems with this, then we can postpone them. They have seen quite some test exposure though, since I wrote them some months ago. Anyway I'd want to postpone any moving of functions until we use something better than CVS and viewcvs. Note the shell function markers are not needed any more. They were added by Peter on 2004-12-20 and went obsolete by the change by Peter and Alexandre on 2005-04-17. I'm removing them, now that we'd need a lot more of them.

FYI: HEAD: new export.at test
The new cmdline_wrap.test fails on most systems. For those not so familiar with this relatively new test: what it does is take the libtool script, set max_cmd_len very low so that all kinds of command line wrapping actions are triggered in link mode. And then all those tests in the testsuite that exercise the plain libtool script, are rerun with the modified script. Of course, if any of those other tests fail for another reason, then cmdline_wrap will also fail, but of course some failure cases are only triggered by it. While looking into this, I noticed several distinct but related bugs: 1) The linker script and reloadable object file generation code assumed that at least one object is present on the command line. The convenience tests showed that many compilers cope with only having convenience archives listed as input to a library. If possible, I would like Libtool to cope with that, because it is convenient for users; if not, then we should start to think about warning against it in func_mode_link. Anyway my current thinking is that we shouldn't give up just yet. (Also, Automake usually needs a source file for a library to be able deduce the right --tag, but that can be worked around by passing that manually in *_LIBTOOLFLAGS.) 2) If there are only convenience archives as library inputs, then using -export-symbols{,-regex} would mistakenly export all symbols. Also, some $EGREP would on some systems try to read a nonexisting file (causing another failure). 3) -export-symbols-regex fails to hide symbols if the command line length was exceeded. The convenience tests run inside cmdline_wrap expose (1), the patch below adds a test adapted from stresstest.at that also exposes (2) and (3) (in conjunction with cmdline_wrap). I would like to fix all failures at once, due to the intertwined code in ltmain. Currently, I'm about half-way through. I'll post what I have in a followup mail FYI, but won't apply it. After this is fixed, there is still a (at least one ;-) scenario where we don't cope with long command lines: if merely the list of passed convenience archives exceeds the limit. But that can be worked around by the user, by simply subsuming some convenience archives in another convenience archive.

Re: [GNU Autoconf 2.60] testsuite: 3 120 failed
On Sun, 11 Feb 2007, Peter O'Gorman wrote: Hi Ralf, Could we test if test -x works and use that? I know that this is barely used, but it bugs me that test -f does not test for the executable bit :) I think autoconf has this: if test -x / /dev/null 21; then as_executable_p='test -x' else as_executable_p='test -f' fi I seem to recall that with some versions of the MSYS shell 'test -x' pretends to work (but does not). It is best to make sure before depending on it. Some systems don't support the notion of 'executable' files.
