problem with genattr on i386-pc-linux-gnulibc

problem with genattr on i386-pc-linux-gnulibc

[Matthew D. Langston]

I received the following error when building egcs-1.0
on a PentiumII running vanilla RedHat 4.2 Linux.

*** Begin error message ***
stage1/xgcc -Bstage1/  -DIN_GCC    -O2 -g -O2  -DHAVE_CONFIG_H   -o genattr \
 genattr.o rtl.o ` case "obstack.o" in ?*) echo obstack.o ;; esac ` ` case "" in ?*) echo  ;; esac ` ` case "" in ?*) echo  ;; esac ` 
./genattr ./config/i386/i386.md > tmp-attr.h

make[1]: *** [bootstrap-lean] Error 2
make[1]: Leaving directory `/home/work/projects/rpm/BUILD/egcs-1.0/gcc'
make: *** [bootstrap-lean] Error 2
*** End error message ***

I configured and built egcs-1.0 *in the egcs-1.0
source directory* as follows:

  langston@seto$ ./configure --prefix=/usr/local --enable-shared i386-pc-linux-gnulibc
  langston@seto$ make bootstrap-lean

However, egcs-1.0 builds absolutely fine when I don't
pass `configure' a target name (which, in my case,
defaults to `i686-pc-linux-gnulibc1').

I am building RedHat RPMs of egcs-1.0 for my site, so
I must pass the `i386' target type to configure.

Also, since I am building RedHat RPMs, I must build
egcs-1.0 in the source directory.  This is contrary to
the advice given at
http://www.cygnus.com/egcs/install/configure.html , but
since I am building RPMs I have no choice but to build
in the source directory.

Can anyone offer insight into this problem?

I am having similar problems with i686-pc-linux-gnulibc1 under redhat
4.2, though using 971201, not egcs-1.0 (yet).  You don't show a core
dump message, but in my case, the linker is coredumping with a SEGV.

I'll have to try omitting --host, maybe it will fix my problems.

I build with a shell script, here is what it does, maybe you can do
the same thing in your .spec file:

    : unpack tar &&
    : cd top-level source directory &&
    mkdir .src &&
    mv * .src &&
    mv .src src &&
    mkdir build &&
    cd build &&
    : configure, make, etc.

Hmmm, this does not look like a problem with egcs -- it looks more
like a system error of some kind.

You should never have to provide a target name for native builds;
if rpms are requiring that, then the rpms need to be fixed.

Avoid the rpms and just build egcs without them.
