I also observed this problem on Ubunto12.04 32-bit. I solved it by adding -D_FILE_OFFSET_BITS=64 to the CXXFLAGS. This problem does not occur on 64-bit Ubunto.
Still we need to see find out why this mismatch is occurring and update out config/make machinery.

This is my first mail list post ,so please forgive my poor Englist or any mistake I'm facting the "undefined reference to `lldb_private::FileSpec::ReadFileContents ..." problem too ,after some digging , seems like this problem is lead by different typedef of "off_t" after compiling FileSpec.o, nm gives: 00001b90 T lldb_private::FileSpec::ReadFileContents(long, void*, unsigned int, lldb_private::Error*) const 00001d80 T lldb_private::FileSpec::ReadFileContents(long, unsigned int, lldb_private::Error*) const but after compiling Host.o ,nm gives: U lldb_private::FileSpec::ReadFileContents(long long, void*, unsigned int, lldb_private::Error*) const same problem applies on following header too: Core/Module.h: Module (const FileSpec& file_spec, const ArchSpec& arch, const ConstString *object_name = NULL, off_t object_offset = 0); Symbol/ObjectFile.h: size_t ReadSectionData (const Section *section, off_t section_offset, void *dst, size_t dst_len) const; force changing these define from "off_t" to "long" ,lldb compiled and run. but I can not assume lldb works OK. and I can not point out why off_t has different meaning in different translation unit. and this is my build environment: llvm svn version: 175324 clang svn version:175313 lldb svn version:175378 build in tree, config with ./configure --prefix=/home/my_name/local_install --enable-optimized --enable-targets=x86 CC=gcc CXX=g++ build host : ubuntu 11.04 32bit, gcc 4.6.3(compiled myself, first append in ${PATH}) ,system gcc: 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu4) (compile with clang also has the same problem) attachment is the compile command in subdir "lldb/source/Host", hopes this can help you 本邮件附件清单如下： (1) make_verbose.txt (23.8 K) comicfans44，[email protected]<mailto:[email protected]> 2013-2-17
