Hello,

I have spent many hours trying to compile some C++ code, using Eclipse on a MAC OSX10 machine. I have removed all other compile errors, but I am just left with this one. There a is a -l at the end on the linker command. How can I remove this text from the line?

Many thanks, in advance.

Graham.

Hello Again,

After more investigation, I have discovered that the -l"" comes from the inclusion of a Mac Framework. I have included the framework as a library in the project properties -lIOKit -framework. Without the '-framework' argument, the library is reported as not found. with the '-framework' argument it is found, but then it has the -l"" in the linker command. If I do not add the Mac Framework, the compiler creates errors, saying that the IOKit does not have symbols appropriate to the architecture X86_64. This is using the default IOKit.framework under /System/Library?Frameworks. In order to get rid of these errors, the project must include the IOKit.framework from the MacOSX10.8 SDK, which is a 64 bit version.

I hope that this information will enable someone to identify what I am doing wrong here.

Thanks,

Graham.
