Re: Problem while configuring gcc3.2
2009/12/28 Pardis Beikzadeh: Hi, This question should be asked on the gcc-help mailing list, not this one. I'm having a problem while installing gcc3.2. I'm trying to install gcc3.2 for my installation of cygwin because anything higher than that won't work if I try to compile mex files for Matlab. Unfortunately when I try to configure gcc3.2 (before getting to the bootstrap step), I get an error because no proper cc is found. This is of course because I uninstalled my gcc3.4 in order to install gcc3.2 from scratch according to the suggestion in the email below from the gcc mailing list. Could you please tell me how to solve this problem? I don't see any suggestion in the mail you quoted that says to uninstall gcc3.4 I suggest you don't uninstall gcc3.4 and instead configure gcc3.2 so it installs to a different path. That way you will have two versions installed in separate locations. Where can I get an installation of cc that will work with gcc3.2? It seems like I'm stuck with a chicken and egg problem because it seems like I need gcc before I can install gcc. Also 'make bootstrap' doesn't work without running configure, so I'm not sure what the recommended way mentioned in the email below means. It means following the usual installation instructions given on the gcc website, which say to run configure first. Once you've configured you can run 'make bootstrap'

The bootstrap in Jim's reply means, I think, building a minimal (only C front-end) gcc-3.2 first using gcc-3.4. Then you can use the minimal gcc-3.2 to build a full gcc-3.2. Maybe installing a gcc-3.3 based Cygwin-release like the '1.6.6' and then building gcc-3.2 with it would succeed immediately : http://www.filewatcher.com/m/cygwin-1.6.6.zip.496537660.0.0.html Or simply finding a gcc-3.2-based Cygwin-release from the net It can also be possible that gcc-3.2 expects some old Cygwin-runtime as the binutils C-library components, trying to get gcc-3.2 to work with uptodate binutils and Cygwin-runtime may simply be impossible or very hard :(

After reading your suggestion I tried to find an older installation of Cygwin. I found one but I have yet to try it and see if in fact gcc3.2 does solve my other problems. Cheers, Pardis Beikzadeh

Gcc-3.4 did not exist when gcc-3.2 was released, so it was impossible to make sure that gcc-3.2 would compile OK with gcc-3.4 when gcc-3.2 was released. Since we are no longer maintaining gcc-3.2, we aren't going to fix this. If you build gcc-3.2 the recommended way, e.g. via bootstrap, then you won't run into this problem. The fortran front end will be built by the bootstrapped gcc-3.2 instead of gcc-3.4, and you won't get this error. If you are building a cross, then you bootstrap a native gcc-3.2 first, and then use the native gcc-3.2 to build the cross gcc-3.2. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
