gcc-15 support?

Yarda — Mon, 14 Apr 2025 17:13:35 -0000

gcc-15 defaults to the C23 standard. With gcc-15 tclx compiles with the -std=gnu17, but not with the default setting. Attached is patch that fixes several problems (not all, there are more problems to fix). Maybe it can be resolved better by refactor.

Tcl 9 support?

Yarda — Mon, 14 Apr 2025 14:03:46 -0000

Recently, stable Tcl 9.0 package has been released. There are many changes and TclX doesn't compile with it. Is support planned?

#84 Implicit declaration of sleep, exit in configure tests

Sam James — Tue, 22 Nov 2022 23:49:51 -0000

There seems to be a newer version available at https://github.com/flightaware/tclx. Patch for that at https://github.com/flightaware/tclx/pull/15.

Implicit declaration of sleep, exit in configure tests

Florian Weimer — Fri, 18 Nov 2022 12:00:34 -0000

These implicit declarations always fail with compilers in strict C99 mode. The patch below should fix it.

tclconfig/tcl.m4 has been fixed in Tcl itself.

Is cross-compilation possible?

Full Name — Tue, 10 Aug 2021 14:46:34 -0000

The configure script over at https://github.com/flightaware/tclx , denies cross-compilation.
Is it possible to fix it with a patch or does it need lot of work?
(I'm trying to build aarch64, arm, etc... on a x86_64 system)

#54 tclx cvs head core dump

michel bruant — Thu, 09 Apr 2015 14:51:40 -0000

Hi Mikahail,

I patched tclx with your version 1.5 of tclXprofile.c ; because I faced the same issue described here.

I still have a segmentation violation. It is improved because I think the profiler is now called back by tcl. But (line556) : infoPrt->savedCmdInfo.objProc is a null pointer.
Please tell me if you think another patch can be done for that.
Many thanks;
Michel

Multi-process tests in 8.4.1 fail under Tcl-8.5

Mikhail Teterin — Sat, 02 Aug 2014 01:01:33 -0000

Though under 8.6 things aren't too bad, under 8.5 there are too many failures to believe, a test-run was attempted before the 8.4.1 release was cut.

The pipe.test script simply hangs forever (on FreeBSD, at least). Various process-tests fail in a variety of ways. signal.test also reports:

Tcl_FinalizeNotifier: notifier pipe not initialized

and fails...

#54 tclx cvs head core dump

Mikhail Teterin — Sat, 02 Aug 2014 00:45:31 -0000

Larry, if -- five years later -- you are still interested in TclX and its profile-command, please, try this patch -- in particular, the last part of it, which patches tclXprofile.c

The changes modify TclX code to use the official API-calls instead of modifying the internal structures directly. Two of the tests inside profile.test will fail (4.2 and 4.4), if used with Tcl-8.6 -- because ::error is now "internal". Everything else ought to work as before. Let me know... Thanks!

#81 commandloop freezes on windows

Jarek Czekalski — Wed, 02 Oct 2013 06:44:42 -0000

Sorry for the typo: changing to "off" makes it work, the script code is correct.
(I am unable to edit the entry)

commandloop freezes on windows

Jarek Czekalski — Wed, 02 Oct 2013 06:43:01 -0000

The following script causes a freeze:

package require Tclx
commandloop -interactive on

Changing interactive mode to "on" makes it work ok.

I tested on various tcl versions with same results: 8.5.14, 8.6.1, Active Tcl 8.5. Tclx version in use: 8.4.1. All programs (except Active) were compiled using mingw.
