My versions of SCILAB are 5.5.2 and 6.1.1 but I can't find the module that contains laplace, if I try to use it it says:
" !--error 4
Undefined variable: laplace"
I tried to use: "exec('Loadsignal.sci')"
but it returns:
" !--error 241
File "Loadsignal.sci" does not exist"
What else can I do?

This is the whole error I get.
Does anyone know how to fix this.
The previous threads are old/ the solutions for them didn't work.
I tried:
sudo apt-get install ruby-mysql
and got:

as mentioned here you need to install a few Linx packages first before installing the gem
I am writing a function that i want to include in a user-defined package (MYPACKAGE). The function is a follows:
readSchedule <- function(FILE){
WB = loadWorkbook(FILE)
WS= readWorksheet(WB, sheet = 'Sheet1',header = TRUE)
return(WS)
}
where FILE is the name of the Excel file i want to read. When writing this function, I want it to import XLConnect, since that is the package it uses. I placed header code defining the function:
#param FILE Excel file
#return Excel data
#export
#import XLConnect
I have also added import(XLConnect) to the NAMESPACE and the DESCRIPTION file of MYPACKAGE. The package builds fine (or at least at first cut it appears to build OK) but when i run "Check Package" it fails and gives me the following error:
* installing *source* package 'MYPACKAGE' ...
** R
** preparing package for lazy loading
** help

Error : .onLoad failed in loadNamespace() for 'rJava', details:

error: No CurrentVersion entry in Software/JavaSoft registry! Try re-installing Java and make sure R and Java have matching architectures.
Error: loading failed

ERROR: loading failed for 'i386'
I have the correct version of Java and can load rJava just fine. i've tried importing rJava (similar to XLConnect) but i get the same error. Below is my sessionInfo:

It looks like you are building your package on a Windows 64-bit machine with a 64-bit version of Java installed. When checking your package using R CMD check, R by default also attempts to check your package on other sub-architectures (i386, 32-bit) which in your case would in addition require a 32-bit installation of Java.
If you want to check your package also for i386 you may just additionally install Java 32-bit. The other option is to pass the option --no-multiarch to your R CMD check call, e.g. R CMD check --no-multiarch MYPACKAGE.
What kind of regex spells I need to put to Eclipse 'Regex error parser' to get PC Lint prints to "problems" view (in Eclipse C/C++ Kepler).
Current lint format is -"format=LINT %t%(: %f:%l %) %n %m"
which prints:
LINT Info: Y:\path\to\file.c:91 732 Loss of sign (assignment) (int to unsigned long)
What I need is first identify that is it info, warning or error and then get:
1. File: 'Y:\path\to\file.c'
2: line: '91'
3: description: '732 Loss of sign ...'
I found one example which did not work for me (most likely the format is different) and I've tried to create my own regex command unsuccessfully.
It is also possible to change the PC-Lint format if it helps.
We are using the following format option:
+ffn
-"format=\q%f\q,%l %t[%n]: \t%m\n"
And our Eclipse regex is:
"(.*\\.*\\.*(h|cpp))",([0-9]*).*((Note|Warning|Error|Info)\[[0-9].*\]): *(.*)
File is $1 Line is $3 and as Description we used Lint $4 $6
Which turns into something like:
Lint Warning[534] Ignoring return value of function...

I am writing a kernel extension in AIX 6.1. I use the "kget_proc_info()" for getting info of a process. But there is a error when I make it:
1>ld : 0711-317 error : Undefined symbol: .kget_proc_info
And I use command "nm" to check this symbol：
#nm -A -X64 /unix | grep kget_proc_info
/unix: .kget_proc_info T 3702624
/unix: kget_proc_info D 45909296 24
I can't understand the difference between ".kget_proc_info" and "kget_proc_info".
How to solve this problem?
You don't actually "link to" the kernel. Instead, you tell the loader, "this list of symbols will be resolved by /unix" and that list comes from kernex.exp. You do that with -bIkernex.exp. The book will help. There are also bos.adt.samples that give you (some very dated) examples.

I'm fairly sure the problem is in my ext/puzzle/extconf.rb file, in that I am not linking the library correctly. I have already posted on ffi/ffi's issue tracker about it and followed up on those two leads with no success.
I would really appreciate any and all help here; been banging my head against the wall for quite sometime on this.
