Hi Thomas,
Which host are you using to build the tools chain on/for?
What's the URL for the instructions you are referring too?
(I want to make sure we are talking about the same page)


I have updated the build-tools/recipe.linux to build a hppa-linux
cross compiler. And my builds now die with:
...
/linux/pa32/xc-build/build-gcc/gcc/xgcc -B/linux/pa32/xc-build/build-gcc/gcc/ -B/opt/puffin/hppa-linux/bin/ -B/opt/puffin/hppa-linux/lib/ -isystem /opt/puffin/hppa-linux/include -shared  .libs/adler32.o .libs/compress.o .libs/crc32.o .libs/deflate.o .libs/gzio.o .libs/infblock.o .libs/infcodes.o .libs/inffast.o .libs/inflate.o .libs/inftrees.o .libs/infutil.o .libs/trees.o .libs/uncompr.o .libs/zutil.o   -Wl,-soname -Wl,libzgcj.so.0 -o .libs/libzgcj.so.0.0.0
/opt/puffin/hppa-linux/bin/ld: cannot open crti.o: No such file or directory
collect2: ld returned 1 exit status
make[1]: *** [libzgcj.la] Error 1
make[1]: Leaving directory `/linux/pa32/xc-build/build-gcc/hppa-linux/zlib'
make: *** [install-target-zlib] Error 2

This is already in the install phase - so the build completed.
"ls -l" tells me hppa-linux-* stuff in /opt/puffin/bin was replaced.
The recipe.linux seems to have mostly completed.

I can't reproduce this error since I don't actually follow the posted
instructions anymore...got tired of maintaining those. It was simpler
for me to just maintain the build-tools/recipe.linux script.

hppa1.1-linux- prefix is obsolete.
Please post either the URL where you found that or (better) a patch for
the URL of what you think the help/instructions should say.

Uh...that's what it's supposed to be.
(I'm not going to consider if it is or isn't logical.  :^)

Try:
  mount -o remount,rw /

and check the /etc/fstab entry for /. Should be something like:
    hpisp747:/tftpboot/hppa   /   nfs    defaults,errors=remount-ro   0  1
