Install Eclipse 32bit AND Eclipse 64Bit on same Computer? [message #1691615] Wed, 08 April 2015 13:50 Go to next message

I have Eclipse 64 bit and MinGW 64bit setup on my win 8.1 64 bit computer. All runs correctly

If I download the Eclipse 32 bit it requires MinGW 32 bit. However MinGW 32 bit overwrites the MinGW 64 bit files if I install the MinGW32 bit into the MinGW directory that has the MinGW 64 bit files. Since both Eclipse 64 bit and Eclipse 32 bit require the C:\MinGW directory, how can I run Eclipse for 32bit and 64bit on the same computer?

First, I don't do C/C++ on Eclipse. You should ask about such issues in
the Eclipse CDT forum.

This said, there is no problem __running__ both versions of Eclipse on
the same host even at the same time as long as you wire them each to an
appropriately bitted JRE.

Hope this helps.

Are you unable to prevent that?

No I'm not able to prevent MinGW 32bit ffrom overwriting MinGW 64bit in the C:\MinGW directory. Since both Eclipse 32 and Eclipse 64 look for the C:\MinGW there is no way to have separate MinGW 32bit and MinGW 64bit directories. Right now I have Eclipse 32 on one computer and Eclipse 64 on another computer.

Am I missing something here? Is there a version of MinGW that will install both 32bit and 64 bit files so that both Eclipse 32bit and Eclipse 64 bit can find them in the C:\MinGW directory?

I have asked in the C++ CDT forum.

I have both 32bit and 64bit Java and yes without MinGW Eclipse 32bit and Eclipse 64bit run fine. MinGW is needed for C++, C, etc
