Project->linker settings->linker libraries

[gomer]

Hello,

I have observed some odd behavior when building a project.  I have tried a number of different ways to specify the libraries for a project to investigate this further, but I will only list the last one as an example:

The project and target, both have the identical set of libraries. (I used "Copy selected to...").  If I use "Append target options to project options", then the link works. If I use "Use target options only", then the link fails with unresolved references.  Given that both project and target have the same set of libraries, how is this possible?

thanx

You can try to debug it by setting:

Settings -> Compiler & Debugger -> Other settings -> Compiler Logging to Full command line

[gomer]

Thanx for the response. 
I took your advice and set logging to Full command line, but it didn't offer any additional insight as to why there are unresolved references when using "Use target options only".

Look at the differences in the link command or post them here, also the errors....

It looks like there might be a problem with mingw32. 

Here is the log that worked :
