llvm dev - Oct 2009 - [LLVMdev] Problem when build LLVM

Hi,

 When i make LLVM with llvm-2.5.tar.gz an error  occurs. The step is below

tar -zxvf llvm-2.5.tar.gz
cd llvm-2.5-tar.gz
make ENABLE_OPTIMIZED=1

Then then the  error is:

/tools/IUS611/tools/lib/libgcc_s.so.1: version `GCC_4.2.0' not found
(required by /usr/lib/libstdc++.so.6)

What shall i do to avoid it?

I am a newbie, maybe it's a foolish question

Regards

After reading //llvm.org/PR896 i make it again as below step

configure --disable-shared
make ENABLE_OPTIMIZED=1

It still reports same error message

Hi Heyu Zhu,

you can get this if you compile C++ code using a different compiler to
your system compiler.  Based on the error message, your system compiler
is gcc-4.2 and the other compiler is probably gcc-4.3 or later.  What
has happened is that LLVM has been linked using the system libstdc++,
which is from gcc-4.2, and which requires libgcc from the same version
of gcc, namely gcc-4.2.  However it is getting libgcc from the other
compiler and complaining.  What you need to do is to link with the
version of libstdc++ that came with the other compiler.

Ciao,

Duncan.

According to your description i should not use the system libstdc++ and i
need to
specify the OTHER compiler libstdc++. But i don't where the OTHER compiler
libstdc++ is.
Is the  OTHER compiler libstdc++ contained in llvm-2.5.tar.gz? if not where
can i get it?
