#9 Building RTSS on Vista with LCC-win32

[Anonymous]

I got the following when I tried to use the precompiled rtss under windows vista:

Startup execution:
loading initial environment

-->exec c:\robot\loader.sce;

-->exec c:\robot\demos\rt_demo3.sce;

So I tried compiling rtss under Vista with the LCC-win32 compiler configured in Scilab and got the following:

Is this a problem with my LCC-win32 or RTSS?
librtsrc.lib was created but librtsrc.ilib was not created therefore it could not be opened.

Hello,

it is a known issue that prebuilt RTSS doesn't work with Scilab-4.1.2 running on Windows Vista (see the bug report #1820632 at http://sourceforge.net/tracker/index.php?func=detail&aid=1830632&group_id=206553&atid=998060\).

>> So I tried compiling rtss

As I suggested in the bug report, this could have fixed the problem. Unfortunately, despite that I thought, even by compiling the source version of RTSS on Windows Vista, the problem occurs anyway. Infact, at long last, I could test RTSS on a Vista system and I noticed that both the distributions (prebuilt and source) have trouble executing some /particular/ commands. As an example --among others-- an exception is thrown when attempting to operate on text strings in a robot object:

-->exec robot\models\rt_puma560.sce;

-->p560.name = "TEST";
Warning !!!
Scilab has found a critical error (EXCEPTION_ACCESS_VIOLATION)
with "librt" function.
Scilab may become unstable.

warning: stack problem..., cleared

-->

Without going into details, by typing the command p560.name = "TEST", the Interface Program sci_rt_ins_c_in_robot (see robot\sci_gateway\sci_rt_insertion_in_robot.c) is executed, but it always crashes executing the "realloc" at line 72: R->name = (char *) realloc(R->name, (strlen(*pv) + 1) * sizeof(char));.

Instead, all works fine under Windows XP. Therefore, according to this and to other similar examples, it can be supposed that there is a problem with the build process for /external/ toolboxes on Windows Vista with VS 2005. I pointed out the problem to Scilab Developers and this issue should be fixed in Scilab 5.

In all honesty, I had never tried to build RTSS with the lcc-win32 compiler. I get the same error as you building RTSS both under Windows Vista and XP. I will go more into the question in the next days.

Thanks for your interest in RTSS.
