compiling withoug glibc

compiling withoug glibc

[David H. Lynch Jr]

    I have several projects that need to be built using GCC but
absolutely no external libraries, headers etc.
    not glibc, not uClibc, nothing.

    I also need to do this under both windows and Linux.

    I have been somewhat successful by renaming directories inside the
crosscompiler subdirectory so that gcc, ... can't find any standard
libraries etc.

    But I can not get this to work uniformly accross platforms, and I
can not trivially reverse it when I do need glibc.

    I have the vaguest clue that doing this has something to do with
triggering gcc to run through different peices of the "specs" file,
    but what I can find of documentation is opaque too me.

    A clue would be greatly appreciated.

David,

You should probably post this question to the crossgcc mailing list:
mailto:crossgcc@sources.redhat.com

Cheers,
g.

Hey,

did you try the options "-nostdlib -nostdinc"?

cheers
