Top Forums Programming How to access a C function from a shell script? Post 302979195 by Don Cragun on Wednesday 10th of August 2016 03:53:00 PM

I didn't say that writing a C compiler in shell was annoying; I said that shell is the wrong language to use to write a C compiler.

Of course, another option would be to write an emulator for the CPU and GPU you're using to execute the program you want to trace, trap the various multiplication instructions supplied by those chips, and capture the operands that those instructions will process. Again, the shell programming language is not a good choice for this project.

Your specifications for what you are trying to do are still extremely vague, but this is not the kind of major research project you are likely to find lots of volunteers in a forum like this to help you. If you produce a clear specification of what you're trying to do, show us that you have written a significant amount of code working towards you goal, and you get stuck on something, we'll be glad to help you get around your roadblocks. If you want us to design and write a project like this for you, I doubt that you'll find any volunteers here to do that for you.

I wish you good luck.

PS: Note that I also advised a friend about 35 years ago that COBOL wasn't a good language to use to write an operating system as a class project, but she did it anyway and got an A in the class. Note also that she was an expert in COBOL and had developed a detailed specification of exactly what that operating system was supposed to do.

platform::shell(n)					       Tcl Bundled Packages						platform::shell(n)

__________________________________________________________________________________________________________________________________________________

NAME
platform::shell - System identification support code and utilities SYNOPSIS
package require platform::shell ?1.1.4? platform::shell::generic shell platform::shell::identify shell platform::shell::platform shell _________________________________________________________________ DESCRIPTION
The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell. This package allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only requirement is that the other shell (identified by its path), is actually executable on the current machine. While for most platform this means that the architecture of the interrogated shell is identical to the architecture of the running shell this is not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run 32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers. For applications like a code repository it is important to identify the architecture of the shell which will actually run the installed packages, versus the architecture of the shell running the repository software. COMMANDS
platform::shell::identify shell This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell. platform::shell::generic shell This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell. platform::shell::platform shell This command returns the contents of tcl_platform(platform) for the specified Tcl shell. KEYWORDS
operating system, cpu architecture, platform, architecture platform::shell 1.1.4 platform::shell(n)
