#yocto cmake configurations

[Monsees, Steven C (US)]

[-- Attachment #1: Type: text/plain, Size: 567 bytes --]


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

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

/disk0/scratch/smonsees/sbcbSTD_SDK/limws/3.0.4/sysroots/x86_64-pokysdk-linux/usr/libexec/x86_64-poky-linux/gcc/x86_64-poky-linux/9.2.0/real-ld: cannot find -ldrm_intel
/disk0/scratch/smonsees/sbcbSTD_SDK/limws/3.0.4/sysroots/x86_64-pokysdk-linux/usr/libexec/x86_64-poky-linux/gcc/x86_64-poky-linux/9.2.0/real-ld: cannot find -ldrm
/disk0/scratch/smonsees/sbcbSTD_SDK/limws/3.0.4/sysroots/x86_64-pokysdk-linux/usr/libexec/x86_64-poky-linux/gcc/x86_64-poky-linux/9.2.0/real-ld: cannot find -lclang
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 see its using -rdynamic -static
so next question is that do you have .a files in your sdk ?

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

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.

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 ?

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).

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...

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

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 ?

Re: [yocto] #yocto cmake configurations

[Monsees, Steven C (US)]

[-- Attachment #1.1: Type: text/plain, Size: 15652 bytes --]


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 ?

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 ?

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
