[Bug c/43073] New: building arm cross-compiler fails when attempting to build regex library

[eric at brouhaha dot com]

I can bootstrap a cross-compiler with no target system library with GCC 4.3.3,
but using the same configuration options causes a failure when building GCC
4.4.3.  It appears to be attempting to build the regex function of libiberty
for the target, and failing because there isn't a target system library
available.  I'm not sure why 4.4.3 wants to build that when 4.3.3 did not.  My
configuration options are based on what Codesourcery uses for arm-none-eabi in
their 2009q3 toolchain.

Configuration:
../gcc-%{version}/configure \
  --prefix=/usr \
  --mandir=/usr/share/man \
  --infodir=/usr/share/info \
  --target=arm-none-eabi \
  --disable-libmudflap \

------- Comment #1 from ramana at gcc dot gnu dot org  2010-02-16 11:20 -------

What happens if you use make all-gcc all-target-libgcc on the top level of your
object tree rather than using make all.


Also, it's not necessary that all options supported by the Codesourcery
toolchain should work with the FSF toolchain.

For instance using this with the FSF toolchain is not correct and will create
more problems for you later.

Did you download gcc-4.4.3-core.tar only?  Or the full gcc-4.4.3?

The problem shows up with gcc-core only.
