I see its using -rdynamic -static

so next question is that do you have .a files in your sdk ?

My standard zeus SDK appears to have an issue linking in my applications dynamic libs…

collect2: error: ld returned 1 exit status

The libraries are under: /disk0/scratch/smonsees/sbcbSTD_SDK/limws/3.0.4/sysroots/corei7-64-poky-linux/usr/lib/

 

My CMake build app does not appear to have an issue finding the files:

 

DRM_INTEL_LIBRARIES:STRING=/disk0/scratch/smonsees/sbcbSTD_SDK/limws/3.0.4/sysroots/corei7-64-poky-linux/usr/lib/libdrm_intel.so

DRM_LIBRARIES:STRING=/disk0/scratch/smonsees/sbcbSTD_SDK/limws/3.0.4/sysroots/corei7-64-poky-linux/usr/lib/libdrm.so

 

It appears to be an issue specifically with the ld…

 

LDFLAGS= " --sysroot=$ENV{OECORE_TARGET_SYSROOT} -L$ENV{OECORE_TARGET_SYSROOT}/usr/lib -L$ENV{OECORE_TARGET_SYSROOT}/usr/lib/x86_64-poky-linux/9.2.0 -lpthread -pthread -O2 -pipe -Wl,-O1 -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed"

 

It does not appear to be making use of –L’s…

 

Is there something I might look at/configure (i.e. add paths to search paths) ?

Is there a simple test to validate tool ?

 

Thanks,

Steve

I am using zeus, standard SDK, cmake…

 

Can I pre-configure the SDK to setup cmake package search paths ?, say for find_package, etc. (i.e. detecting external libraries/programs)…

 

The majority of my env is configuring properly, but I am finding cmake is setup for a standard linux env with regards to these types of searches, and

I wanted the cmake built in to look at my SDK paths (first by default) when doing such things as detecting python interpreter, libraries, etc.

 

I am working on third party package unaware of my SDK setup.

 

Thanks,

Steve
