error: ld: bad codegen, pointer diff in EH_frame1 to global weak symbol

[Michael_B_19]

Hi. First off, thanks for all the help that you offer through this forum. In the past, I've found the responses to be both helpful and polite. Second, the problem below occurs on Mac OSX 10.7.2, running icpc version12.1.0 20110811.

\\

Consider the following short code:

#include

int main() {

std::cout << "hello world\\n";

}

\\

If I compile with: icpc icctest.cpp, there is no problem. All runs well.

\\

But, if I compile with icpc -g icctest.cpp, I get the following warning:

\\

no debug symbols in executable (-arch x86_64)

\\

That, by itself, if no big deal. In fact, the executable runs.

\\

However, for more complicated projects, if I compile without debugging information, all works fine. But as soon as I add the -g flag (or the -debug full flag), I get the following error:

\\

ld: bad codegen, pointer diff in EH_frame1 to global weak symbol SOME_SYMBOL_NAME for architecture x86_64

\\

Thus, the build fails.

\\

This happens even if I am not linking to external libraries; the symbols are from some header-only libraries. And itdoes not happen with g++. It is only with the Intel compilers.

\\

After some deep digging online, it seems like this might be related to debugging symbols being placed in a .dSYM directory. I've never really noticed that directory before. But when I go into the directory, and eventually get to the DWARF directory in there, I get:

\\

nm a.out

nm: object: a.out malformed object (section contents at offset 0 with a size of 160, overlaps Mach-O headers at offset 0 with a size of 1952)

\\

There will be a similar message for the simple Hello World example above, as well as some of the more complicated projects.

\\

I have found some references to changing XCode options to avoid placing debugging symbols in the dSYM directory, but since I usually work on a command line, that does not help me much.

So I am now at a loss as to what to do next. Any ideas? Thanks in advance.

\\

I just realized that my developer tools were XCode 4.1. I upgraded to XCode 4.2.1, also also upgraded to icc 12.1.2 20111207. Now the error message is as follows:

$ icpc -g -xHost -m64 icctest.cpp

Again, this happens with icpc, but not with g++ 4.6.1.
