Linux or Windows? |

I am looking for a C compiler for the pic16f87. I'd rather use Linux, but if the Windows version is much better I will go with that. Can anyone share their experience? Thanks. |

I can't comment on any experiences with the compiler for Linux because I bought the one for Windows. I can say that the PCM compiler for Windows will integrate with the Microchip MPLAB (which is compatible with all of their programmers and emulators) and therefore provide a complete IDE for developement. The compiler will also work from the command line in both versions.
On the other hand if you are comfortable with programming in Linux, it may be possible to configure one of the available IDE's to use the PCM compiler for its output. Just make sure you have a way to program the chip from Linux.
Someone who has the Linux version could be more helpful I guess. |

Get the Windows one...
You can use WINE to use the Windoze one in Linux. |

It doesn't really matter wether the compiler is in Linux or Windows. What you should be concerned with is how well the compiler works in general. I would go with Windows due to the amount of tools out there. |

Thanks for the advice. We will probably go with the Windows one since it is older and probably more mature, we we can integrate the compiler into the MPLAB IDE, and we can run it via wine if we want to compile things from Linux. Thanks again. |

Hello
Quote: | You can use WINE to use the Windoze one in Linux. |
Can you tell me if there are any special things you have to do, to get it to work with wine? Did you ned special dlls?
I have pcm 2.734 an it does absoluetly not work with wine (picchips does sometimes)
Many thanks

windoze compiler in linux w/ wine |

Hi,
I use the windows compiler in linux, however my version is 3.176 (as of PCM). Can you tell more how the wine acts when you run the compiler? First general problem is that the compiler command line is not something linux really likes, so I made a little wrapper script, that converts some basic GCC like options (like -I -D) to something the linux compiler understands and invokes it via wine. Beneath is code snippet. I also have a special option to which compiler to run (PCH/PCM) and separate handling for their options as the that I use had different command line options. Here it is:

Hello
Command lines and resulting wine error messages:
>wine pcm.exe
This seems to be a very old (pre-3.0) Windows executable. Expect crashes, especially if this is a real-mode binary !
Could not load 'RTM.DLL' required by 'PC', error=2
If I put a rtm.dll (fopund in www) in the same directory as pcm:
>wine pcm.exe
This seems to be a very old (pre-3.0) Windows executable. Expect crashes, especially if this is a real-mode binary !
Could not load 'RTM.DLL' required by 'PC', error=21
If I want to use pcm without IDE (with -C) the errors ar the same.
Many thanks

Don't use PCM.EXE. PCM.EXE was an old Borland style DOS IDE. It hasn't been supported in a long time.
Use CCSC.EXE, which is the command line compiler. |

Look at this!
With ccsc.exe it does work very nice!
I used pcm.exe also on Windows systems because my manual say that's the way you should invoke the DOS compiler (ok it isn't the newest manual)
Many thanks!
