similar to: [PATCH nbdkit] Add Tcl plugin, for writing plugins in Tcl.

Dear R developers, I plan to upload a first version of my R package RnavGraph to the R CRAN server in a week or two. However I'm still struggling with an image resizing function written in C as a tcl extension. I did all my development in Ubuntu, and everything works fine in Ubuntu, however my attempts to compile this C function under Windows or OSX have all failed. I provide a minimal self

Hi ho folks: I'm running the indicated version of R on Hardy Heron Ubuntu. (Yes, I am quite aware that it is considered old news but then I don't run the "latest and greatest" computer gear. I've tried both Gnome and KDE editions of Ubuntu Lynx and even a current run of Fedora. I find Heron simply works better on my machine.) When I try to install RcmdrPlugin.PT most of

Hello, Up to R 2.6.2, I used to start Tcl *without Tk* (I need only Tcl for some part of my work, like a socket server written in Tcl only, for instance) with this code under Mac OS X (particularly on this system, because I don't want to start X11 just to use Tcl code, which is required for Tk!): > Sys.unsetenv("DISPLAY") > library(tcltk) I got then the message

So this wasn't tested for a month? Anyways, Free() is just free() with a check that we're not freeing a null pointer, followed by setting the pointer to NULL. At that point of tcltk.c, we have for (objc = i = 0; i < length(avec); i++){ const char *s; char *tmp; if (!isNull(nm) && strlen(s = translateChar(STRING_ELT(nm, i)))){ // tmp =

Ah, I see it now: The remapping of free() to Rm_free() and calloc() to Rm_calloc() happens in memory.c, but not in tcltk.c; the macro Calloc in R_ext/RS.h maps to a call to R_chk_alloc which is defined in memory.h; RS.h is included in tcltk.c, so tcltk.c winds up calling Rm_calloc() via Calloc(), but then the NON-remapped free(), and the walls come tumbling down. If the "#if

Hi, Does it make sense to withdraw the Windows R 4.0.1 binary until the issue is resolved?

I've committed the change to use Free instead of free in tcltk.c and sys-std.c (r78652 for R-devel, r78653 for R-patched). We might consider either moving Calloc/Free out of the Windows remapping or moving the remapping into header files so everything seeing our header files uses our calloc/free. Either would be less brittle that the current status. Best, luke On Sun, 7 Jun 2020, peter

Dear R-helpers, Christoph (author of phyloclim) and Luke (author of tkrplot), I would like to get your helps on installing of phyloclim in Ubuntu linux. It seems a package named 'tkrplot' could not be installed at firstly, then packages depends on it could not be installed latter. As I have tested, installation of phyloclim works smoothly in Mac. I attempted to install these packages in

While working on can_FOO caching, at one point I got confused by whether 'readonly' meant the global set by -r or a local passed to .open(). A quick attempt to compile with -Wshadow found several other confusing points; this series gets us to the point that we can add -Wshadow to builds with --enable-gcc-warnings.

After configuring my home network, aMSN segfaults. I posted this issue originally in the aMSN forums under this thread: http://www.amsn-project.net/forums/viewtopic.php?t=7593 I was told that my issue is related to SAMBA, referring this thread: http://www.amsn-project.net/forums/viewtopic.php?t=6343 After uninstalling SAMBA, aMSN stops segfaulting and works as expected.
