Khem:

I only have the following libraries present for these:

libclang.so
libclang.so.9
libdrm_intel.so
libdrm_intel.so.1
libdrm_intel.so.1.0.0
libdrm.so
libdrm.so.2
libdrm.so.2.4.0

I do generate the static (*.a) files for both LLVM & Clang and they appear to all be present (No libclang.a was generated).

Steve

the cmd seems to pass --sysroot correctly so can you search in SDK sysroot if you have libclang.a libdrm_intel.a and libdrm.a ?

I see its using -rdynamic -static
so next question is that do you have .a files in your sdk ?

can you post full linker cmd which is failing ?

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
