I'm working on building arm-linux toolchain for GCC-3.4, xscale. I used CROSSTOOL-0.28-rc34/arm-iwmmxt, but the toolchain encountered problem when building a large c++ project. I had another arm-linux toolchain for GCC-3.3.2, which is OK to build that project.
Can you post the error it encountered, and the source snippet that didn't build? It's quite likely that gcc-3.4 is running into something that it is stricter about than gcc-3.3 was.
You are right. The following are errors when building qte-3.04. I have found http://gcc.gnu.org/ml/gcc-patches/2003-07/msg01664.html
describes GCC-3.4 prevents non-const reference bindings to packed
fields. This is correspond to the first error. The second error is
because GCC-3.4 require explicitly using this->clear() instead of
clear().
...
In member function `ushort& QChar::unicode()':
/home/bridge/qpe/qpe-new-glibc/qt-embedded-free-3.0.4/include/qstring.h:178:
error: cannot bind packed field `((QChar*)this)->QChar::ucs' to
`ushort&'
...
gcc-3.4 is a tad bit harder to build than gcc-3.3, if I remember properly.
It is. BTW: It seems that the bootstrap gcc configured with
--with-inhibit-libc option works well. In case what do you consider
with so complex method? :)
Oh, I dunno, probably because I needed it to work with all versions of gcc, and older versions need a different trick. - Dan
