[cfe-dev] undefined reference to `std::basic_string<char>..Error

[Mohit Asudani]

Hi  Clang Developers,

 

I downloaded the latest revision (r123891) of LLVM via
SVN and followed the instructions at http://clang.llvm.org/get_started.html 
to configure and build. 

 

While building I received  following error:

 

Linking Debug+Asserts executable FileCheck

/u/asudani/project/build/Debug+Asserts/lib/libLLVMSupport.a(Program.o):
In function `char* std::basic_string<char, std::char_traits<char>,
std::allocator<char> >::_S_construct<char const*>(char const*,
char const*, std::allocator<char> const&,
std::forward_iterator_tag)':

/usr/software/lib/gcc/x86_64-unknown-linux-gnu/4.1.1/../../../../include/c++/4.1.1/bits/basic_string.tcc:158:
undefined reference to `std::basic_string<char,
std::char_traits<char>, std::allocator<char>
>::_Rep::_M_set_length_and_sharable(unsigned long)

 

Searching for error directed me to forum suggesting
addition of –lstdc++ linker option:http://www.codeguru.com/forum/archive/index.php/t-351875.html.

I tried to modify makefile but it didn’t worked. What is
the best way to modify LDFLAGS for incorporating the specified option ? 

 

 

After looking logs for past revisions, one of them
(r121379) yielded:

 

r121379 | mspencer | 2010-12-09 23:06:48 +0530 (Thu, 09
Dec 2010) | 1 line

Support/MemoryBuffer: Replace all uses of std::string
*ErrMsg with error_code &ec. 

And fix clients.

 

 

I want to know if these observations are related in any
way and if this is known error and has been encountered before by users.

 

 

Thanks 

Mohit Asudani
