Flag -rdyanmic causes compile failure on Mac OS X

[cavinsays]

Hello,

I'm using ICC version11.1 20100203.Trying to compile mplayer from the svn repo, I get a compile failure:

ld: unknown option: -export-dynamic

make: *** [mplayer] Error 1

First, I should say that I'm not a developer (using the trial), but I do have some limited knowledge about these kinds of things.

Next, this has happened before. I tried to compile the latest version of zsh and got the same error.

When compiling zsh, finally realized the -export-dynamic flag comes from the -rdynamic flag. When I did, I searched for the -rdynamic flag in the makefile and took it out (knowing that this would cause errors for dlopen), just to test. Of course, it made a non-functional zsh. So I just gave up.

Now, I am trying to compile mplayer. Again, it uses the -rdynamic flag, causing it to call on -export-dynamic. This causes the build to fail.

If you'll need any more output, I'll be happy to add it.

Any suggestions on how I could fix this? Is there something I couldsubstitue-rdyanmic with in the makefile?

Thanks,

Cavin

Just a first-aid gesture.

I visited this option, though in Linux systems in ld manuals (in Mac it could be different), and saw that its
--export-dynamic option that does the thing thats required. And not -export-dynamic. It seems true that -rdynamic calls --export-dynamic, but -export-dynamic may be coming from somewhere else in your svn. Please check as explicitly with --export-dynamic and then -export-dynamic on small file , and check the difference and let us know if it leads to something.

I'm not 100% sure, but it looks like maybe we're mistranslating -rdynamic (arg to icc) to -export-dynamic (arg to ld) when it should be -dynamic. That seems to be what gcc does (on the mac). I'll look into it some more, but for now you might try changing -rdynamic to -dynamic in your Makefile and see if that works for you.

BTW I was able to do this with zsh, but with mplayer I couldn't get this far. Do you have any tips on how to build mplayer on Mac with icc? I'd like to reproduce that as well.

Thanks!

I've submitted CQ154995 on this issue, I'll let you know what I find.

I am using 11.1 and the -rdynamic flag works but there is no documentation on what it is doing. I found some documentationfor gcc that says the the flag allows the linker to add unused symbols to the dynamic symbol table. Is the Intel compiler doing the same thing?
