# How to resolve Keil uVision 5.0 compilation errors?

In an effort to learn Embedded System Programming I recently installed Keil uVision 5.0. I am using a STM32F development board. At this point all I am interested in is getting STM32 L1 Tutorial #1: Hello, World! (LED Blink) code complied and loaded into the microcontroller. While attempting to build the code I got the following errors. What is the cause of this error?

*** Using Compiler 'V5.06 update 3 (build 300)', folder:
'C:\Doc\Programs\Keil52\ARM\ARMCC\Bin'
Build target 'Target'
Error instantiating RTE components
Error #540: 'Keil::Device:Startup:1.0.0' component is not available for target 'Target'
Target not created.
Build Time Elapsed:  00:00:00

• It seems programming questions aren't enough welcomed here, even the ones related closely to engineering. I think not all of the reviewers think it is okay, but if your question would be closed, I suggest give a try to stackoverflow.com . – peterh Oct 9 '16 at 18:43
• @peterh, I am seeking help to configure a Keil to work with a STM32 microcontroller. I don't understand what do you mean that not all of the reviewers think it is okay. – user8055 Oct 10 '16 at 13:23
• Behind your question, there is a reviewing mechanism where a vote decides if a question is off-topic on the site or not. You can't see this vote, but if you remain between us and put new questions and answers, first you will see that, and later you will be able to take part in it. I voted for this question to remain here, others could think rather you should try stackoverflow.com with programming questions. Their reason that they don't want a programming site, but an engineering site. I think we could (should) be more lenient in border cases. Anyways, in the case of a closure – peterh Oct 10 '16 at 17:47
• it is important to not take it personally, only simply re-ask on the stackoverflow - and, if you have an engineering question in the future, don't leave us but ask this (actually, your reputation will grow even in the case of a closed question). The reputation is the bold number below your nick, currently it is 8. If you post more questions or answer them, it will grow like a rocket, because the site mainly loves the high quality content. – peterh Oct 10 '16 at 17:49
• @peterh general computing hardware and software are off topic on stackoverflow. What is the difference between RTOS and Embedded Linux? – Mahendra Gunawardena Oct 15 '16 at 16:38
