It seems that the hardened specs file is causing the build to fail due
to a failure in adjusting the toolchain or the host system not having
some variables defined.
../../cocoon-toolchain/gcc/hardened-specs.h:48:2: error: #error "You are using
an unsupported system. This header can not be used."
That is the line of interest. I've found the statement that causes this.
#if defined(__i386__) && defined(__linux__) && defined(__ELF__) \
&& defined(HAVE_LD_PIE) && defined(TARGET_LIBC_PROVIDES_SSP)
So, I broke it down like this..
#if defined(__i386__)
#else
#error "i386 not defined"
#endif
#if defined(__linux__)
#else
#error "linux not defined"
#endif
#if defined(__ELF__)
#else
#error "ELF not defined"
#endif
#if defined(HAVE_LD_PIE)
#else
#error "HAVE_LD_PIE not defined"
#endif
#if defined(TARGET_LIBC_PROVIDES_SSP)
#else
#error "TARGET_LIBC_PROVIDES_SSP not defined"
#endif
Which results in the following error
In file included from ../../cocoon-toolchain/gcc/gcc.c:553:
../../cocoon-toolchain/gcc/hardened-specs.h:26:2: error: #error
"TARGET_LIBC_PROVIDES_SSP not defined"
This is because -fstack-protector is failing. SSP is not built in the
first gcc build. Support for it is supposed to be built into glibc-2.5,
however, after some checking, it tells me "cannot find -lssp_nonshared"
whenever I try to compile something with -fstack-protector. That means
that gcc supports it, but it is not installed. How can I be sure it is
installed in glibc? I made sure I am using the newly compiled gcc and
the linker seems to be the new glibc.
After some more research, it seems that something is going wrong with
the first gcc build or glibc is not being linked to properly. I know
HLFS is in development, but the link to the old stable version of the
book is broken. I'm going to try rebuilding gcc after each step just to
see if it builds. This should work right? If bootstrapping builds the
compiler once, uses the first build to build a second and the second to
build a third for comparison, then the compiler should be able to be
built after the installation?
