Bug #: 51159
Summary: build failure with --enable-build-with-cxx in
"gcc-4.6.2/gcc/objc/objc-next-runtime-abi-02.c"
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: objc++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: sebastian.hegler@tu-dresden.de
Created attachment 25837
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25837
Proposed patch.
I am trying to build gcc-4.6.2 with the following flags:
./../gcc-4.6.2/configure --disable-nls --with-ppl=$GCC_BASE
--with-cloog=$GCC_BASE --prefix=$GCC_BASE --with--mpfr=$GCC_BASE
--with-gmp=$GCC_BASE --with-mpc=$GCC_BASE --with-libelf=$GCC_BASE --enable-lto
--enable-gold --enable-bootstrap --enable-build-with-cxx
Everything necessary is prepared in $GCC_BASE.
Eventually, this happens:
.././../gcc-4.6.2/gcc/objc/objc-next-runtime-abi-02.c: In function ‘const char*
newabi_append_ro(const char*)’:
.././../gcc-4.6.2/gcc/objc/objc-next-runtime-abi-02.c:1884:29: error: invalid
conversion from ‘const char*’ to ‘char*’
make[2]: *** [objc/objc-next-runtime-abi-02.o] Error 1
C++ provides the following signatures for strchr:
const char * strchr ( const char * str, int character );
char * strchr ( char * str, int character );
Neither of these matches, making the assignment in "dollar = strchr (name,
'$');" fail. Please find the proposed patch attached (which might break
compilation with C, I don't know C as good as C++).

Have you tried the trunk? --enable-build-with-cxx is really only needed if
your plugin is written in C++.

Fixed in trunk r173723, not fixed in gcc-4.6-branch.
"--enable-build-with-cxx" is an officially supported build option, so it should
work reliably in releases.

But this is not a regression so closing as fixed for 4.7.0.

And it was not really a supported build option, it was an experimental option.

Any chance of seeing the fix backported to 4.6, though?
