Re: #yocto cmake configurations #yocto

Monsees, Steven C (US)
 

 

I made some modification in the cmake modules to adjust for the linker issue below, but now I appear to have uncovered an issue with the static libraries which meta-clang generated under the SDK… (see below)…

 

The link command is attached as “tmp.txt”.

 

There are a lot of these being generated, this is but a subset…

Note:

(1) “workspace_3” is a reference to my build area where I built the STD SDK, why would this be here the SDK should be independent of this are, no ?

                (2) the code with the undefined reference does appear to be missing the proper header file reference

All the libraries are under the SDK here:

 

-L/disk0/scratch/smonsees/sbcbSTD_SDK/limws/3.0.4/sysroots/corei7-64-poky-linux/usr/lib

 

I need the DRM libraries to be picked up correctly, libclang.so may not be required since I have all the static variations available, (added to while testing linker) I have yet to make it through entire build due to linker issue…

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).

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
