Link errors: "ld: fatal: option -dn and -P are incompatible"

venkat_k · 04-28-2010, 04:47 AM

I am trying port a linux application to Solaris.
Getting the following error messages during linking
-------
ld: fatal: option -dn and -P are incompatible
ld: fatal: Flags processing errors
collect2: ld returned 1 exit status
------------

Please tell me whats wrong with it?

Perhaps these options are designed to work with a different linker than the Solaris one. In any case, you need to remove one of them for the command to succeed with Solaris ld.

The issue is i am not at all using those options.
I have a Makefile to build the application in Linux, i am trying to use the same to build on Solaris. I am not using either -dn or -P options as part of this.

You mean these options do not appear in the Makefile ??

Then it does probably appear in other Makefiles or whatever files are used to build your application.

Even i tried to ran the same manually from the command line.

Here is the command:
gcc *.o -o app.exe -lstdc++ -lpthread -Wl,-rpath

This is giving the error message "ld: fatal: option -dn and -P are incompatible"

Please have a look at the command. Am i doing any thing wrong over there?

Well, you are using a C compiler but link with the C++ library and give a DOS extension to your binary. While the latter is not a real issue but just confusing, you should be consistent with the language used.

Is your source code C or C++ ?
What Solaris release are you using ?
What Gnu compiler version ?
Are there specific environment variables set in your shell like LD_OPTIONS ?

I am also facing the same issue.
i.e:
ld: fatal: option -dn and -P are incompatible
ld: fatal: Flags processing errors
collect2: ld returned 1 exit status

How did you solve this ?
