egcs bootstrap bug

egcs bootstrap bug

[Joerg Pietschmann]

Hi,
something goes wrong while bootstrapping egcs-19990629 on
powerpc-ibm-aix4.2.1.0 if objc is excluded from building:

t384@neptun:...gcs-19990629>make bootstrap LANGUAGES='c c++ java'
[snip]
thr-win32.c             ..linked
thr.c           ..linked
creating cache ./config.cache
checking if compiler cc1obj has been built... no
rmdir: 0653-611 Directory libobjc is not empty.
make[1]: Leaving directory `/home/lis5p/t384/gnu/unpack/egcs-19990629'

Indeed, there are still all the links to the source files in the mentioned
directory.

I'll do a full bootstrap meanwhile...

Regards
J.Pietschmann

Problem is failure to link an ordinary c++ program with default compiler
options.

I took egcs from CVS the gcc-2_95-branch.

Reading specs from
/usr/cell/gnu/lib/gcc-lib/hppa1.1-hp-hpux10.20/gcc-2.95/specs
gcc version gcc-2.95 19990629 (prerelease)

./configure --prefix=/usr/cell/gnu --with-shared --with-gnu-as
--enable-version-specific-runtime-libs --enable-languages=c,c++

binutils 2.9.1 "as" was symlinked into the gcc directory so that it is
found and used during "make bootstrap".

I compiled using c++ a program that uses the included STL library. STL
uses exceptions, exceptions require the eh.o from libgcc. libgcc
requires pthreads. The program was not using threads, so only libc was
linked and it has no pthreads -> it fails to link.

I had all tools except autogen installed, but it compiled anyway.

It was not my fault :-). Jeff fixed a bug in expr.c while I was testing the 
new varargs stuff. I've backported the fix to egcs-1.1.2, so you can try 
it. Checkout the revision 12f RPM's on 
< ftp://dev.linuxppc.org/users/fsirl/R5/RPMS/ppc/ >.

Franz.

It appears to me that this error should be ignored, isn't it?
