From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0rc2) Gecko/20020513
Netscape/7.0b1
BuildID:    20020702

Mozilla 1.1 snapshot does NOT compile due to compile error in typeinfo.cpp.

Here is my configure command:

 ./configure --prefix=/opt/gnome  --enable-crypto --enable-java-supplement
--enable-extensions  --enable-boehm

Here is the compile output:

Reproducible: Always
Steps to Reproduce:
1.Configure gcc-3.1 on Linux
2.Pull the latest Mozilla 1.1 source tarball
3.Encompress the tarball on Linux
4.configure the build like this:

 ./configure --prefix=/opt/gnome  --enable-crypto --enable-java-supplement
--enable-extensions  --enable-boehm



Actual Results:  This compile error is received:

make -C gc/boehm

Expected Results:  The code should compile EVEN IF C++ RTTI is NOT enabled.

I will try to re-build with C++ RTTI and C++ Exceptions enabled.

Comment 1

[hacker formerly known as [e-mail]]

That's not a bug.  As the error states, you must enable rtti (off by default),
in order to use boehm.  Compiling that copy of boehm w/o rtti is, afaik,
unsupported.

Comment 2

[Tom Williams]

Well, considering compiling WITH boehm garbage collection WAS requested, the
configure script SHOULD have stopped indicating C++ RTTI support was NOT
requested and is in error because it is obviously a requirement.
The "--enable-boehm" option should REQUIRE "--enable-cpp-rtti" and
"--enable-cpp-exceptions", if that is also required.

The configure script is therefore deficient....

Peace...
