uclibc

[Chris Buxton]

Robert,

In this old post of yours, below, you said that nothing in HLFS is built statically. But in trying to figure out why the butterfly toolchain build failed, I saw that the error message involves a static libraries - it appears to be trying to build a static libstc++ (if I'm reading it right - I'm not a programmer), using the static libssp_nonshared that was built earlier during the gcc-libssp step.

I'm using the uClibc/kernel 2.6 book from 20080108, with package users. If you need more of the build log, I have it all (one great advantage of the package user system).

Here is the command that apparently failed (it's a long one):

Subject: uclibc

Since just before 0.9.29, to current snapshot, I get segfaults when anything 
is linked statically to uClibc. Now I've reproduced it with a very vanilla 
uClibc buildroot, so it looks like a bug with uClibc and not a bug with 
something I'm doing. So I'm not going to try to fix it. I did a bugzilla 
about it at the uClibc site. I did find a workaround, which is to compile 
libc.a with no optimization (-O0). Nothing on an hlfs-uclibc system is linked 
statically, so it doesn't really affect the build.

-fstack-protector-all also causes segmentation faults, which may or may not be 
related to the bug with -static. Libssp seems to work, but there are some 
frustrating issues with the ssp header installation for 
default -D_FORTIFY_SOURCE.

Getting there...
