Sorry for the late reply on recent status.
Bad news:
GCC-4.2.1 can compile smoothly, but Gumstix hangs after "freeing init memory..." It is not really hang, still having echo reply from serial console port, but just can't proceed from that point.
It really depressed me... a lot.
Good news:
GCC-4.1.2 compiles/runs smoothly, with success of sshd, etc... (just tested with latest gumstix build-root + default configurations)
I need to get a quad-core thing to accelerate the compiling process... (I was doing it on a notebook (T7300) in a Ububtu virtual box in Vmware workstation)
In general, it feels good not to have segmentation fault. A privaledge, for programmers, to know that we're not building on some known faulty codes...
Bugs don't bother us as long as we don't see them. lol

Subject: [Gumstix-users] Gumstix-Buildroot using GCC 4.2.1 -- with success

I'm getting tired of the segmentation fault... So I tried GCC 4.2.1, and it passed the initial build round (successfully get .jffs2 files)
--Still having problem with Ruby-- it says can't find ruby, and several warning, but no longer segmentation fault when building, at the very least.
--I don't use ruby at all, so I unchecked ruby in the build, and it then succeeded.
--Verdex 600MHz, w/o bluetooth (but it is enabled by default build file)
1. Download latest gumstix-buildroot;
2. Download the latest buildroot (the original buildroot itself), from svn;
3. Copy the /toolchain/gcc/gcc-4.2.1 directory from buildroot to gumstix-buildroot
4. Modify the file /toolchain/gcc/, (just copy and paste some block), so it can support GCC 4.2.1. It should be pretty obvious, and sorry that I'm new to linux, and I don't know how to make a patch file.
5. Build.
I'll test the httpd/sshd stuff on gumstix later after work to see if it is working now. My next step (if not working) would be to change the uClibc to the latest release version (0.9.29)...
BTW, so many module is not really updated, such as ext2fs... I have to manually extract the ext2fs package to make it to "make"...
I think there should be a easier way to incorporate the latest toolchain build tools, but I need to know what are the files that are patched/changed, and what version of buildroot is gumstix-buildroot based on.
