bitbake with cmake recipe

bitbake with cmake recipe

[Zafrullah Syed]

[-- Attachment #1: Type: text/plain, Size: 507 bytes --]

Hi all,

I am trying to integrate my own package which should use cmake.
I regularly use do_compile() and do_install().

when try this with cmake it fails with error: unparsed line: 'do_compile()'
.

Should I follow this guide in writing my own recipe with cmake?
http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-devtools/cmake/cmake_2.8.11.2.bb

or it would be helpful if anyone can give me some hints regarding writing
recipes with cmake.

Thanks & Regards,
Zafrullah Syed

Pasting your recipe would be useful, but there's a cmake class you can
simply inherit that should just work.

Hi,

My recipe is: http://pastebin.com/xiFdYHNr

Is the cmake recipe will be in this
location? /home/siguser/yocto/poky/meta-openembedded/meta-oe/recipes-support/opencv

Hi Ross,

Is this the correct way to write my recipe with cmake?

DESCRIPTION = "cameracapture application"
SECTION = "examples"
LICENSE = "CLOSED"
PR = "r0"

DEPENDS += "opencv"

SRC_URI = "git://
https://github.com/zafrullahsyed/cameracapture.git;protocol=https;tag=v0.1"

EXTRA_OECMAKE=""

do_configure() {
 cmake ../
}

inherit pkgconfig cmake

Thanks & Regards,
Zafrullah.

You should be able to remove your do_configure().

This recipe uses cmake:

http://git.openembedded.org/meta-openembedded/tree/meta-oe/recipes-connectivity/gnuradio/gnuradio_git.bb

Hoepfully, it is more complicated than you need, but you should be able
to see the cmake related parts.

Hi all,

I am newbie and I am learning stuff.

I have a c++ code and CMakeLists.txt on Github which needs to be run with
Cmake. I am trying to get that code embed into my build using my own
recipe. This is my first experience with Cmake. I have no clue what should
I write in my recipe.

My recipe is as follows:

DESCRIPTION = "cameracapture application"
SECTION = "examples"
LICENSE = "CLOSED"
PR = "r0"

DEPENDS += "opencv"
inherit cmake pkgconfig

SRC_URI = "git://
github.com/zafrullahsyed/cameracapture.git;protocol=https;tag=v0.1"

do_configure() {
    ${BUILD_CXX} cameracapture.cpp -o cameracapture
    }

EXTRA_OECMAKE=""

I know this recipe is wrong, I looked up many other recipes that use Cmake
http://git.openembedded.org/meta-openembedded/tree/meta-oe/recipes-connectivity/gnuradio/gnuradio_git.bb

each of them have their own parameters and functions.

Everytime I build my system I get this error:

ERROR: Function failed: do_configure (see
/home/siguser/yocto/build/tmp/work/armv7a-vfp-neon-poky-linux-gnueabi/cameracapture-0.1-r0/temp/log.do_configure.1410

any tutorial for this.

Can anyone give some hints where I am doing wrong or what should be
included in my recipe?

I believe you must set the S variable in your recipe.

Probably, you must set it to

S = "${WORKDIR}/git"

You just have to look where your sources are located under
"/home/siguser/yocto/build/tmp/work/armv7a-vfp-neon-poky-linux-gnueabi/camer
acapture-0.1-r0/cameracapture-0.1", and set this subdirectory:

S = "${WORKDIR}/subdirectory".

Why you want to compile something during configure? Remove this function.

You don't need this if you don't need to pass additional definitions to 
cmake.

Are you sure this directory exists and contain the CMakeLists.txt file? 
Maybe you have to adjust the S variable to point to the directory of 
your source code.

Hi Stefan,

I updated my recipe:

DESCRIPTION = "cameracapture application"
SECTION = "examples"
LICENSE = "CLOSED"
PR = "r0"

DEPENDS = "opencv"

SRC_URI = "git://github.com/zafrullahsyed/cameracapture.git
;protocol=https;tag=v0.1"

S = "${WORKDIR}/git"
inherit pkgconfig cmake

I have my source file and CMakeLists.txt as tar on github. tar is not
getting downloaded.

--> If I remove tar and keep just source file and CMakeLists.txt, then also
it is not getting downloaded. I am getting

CMake Error: The source directory

--> I copied my CMakeLists.txt file in ${WORKDIR}/git and tried the build,
got this following error:

The tar should be in the "${WORKDIR}/git" directory but it will not work 
as you don't tell bitbake to unpack it.

You repository with tag "v0.1" contains only a README.md!

The common use case is to put all sources into the git repository. Why 
you want to save a tar in a git repository?

Have you check the content of the 
/home/siguser/yocto/build/tmp/work/armv7a-vfp-neon-poky-linux-gnueabi/cameracapture-0.1-r0/git 
directory?

Are you sure you have change the S variable? The error still reference

It looks as something went wrong. Please clear the old package and try 
again or increment the PR number.
bitbake -c cleansstate cameracapture && bitbake cameracapture

No, this are subsequent errors of the missing toolchain.cmake.

This looks okay.

Re: bitbake with cmake recipe

Hi Stefan, Hi all,

My build was successful with CMake. I made some changes to my recipe:

DESCRIPTION = "cameracapture application"
SECTION = "examples"
LICENSE = "CLOSED"
PR = "r0"

DEPENDS = "opencv"

SRC_URI = "git://github.com/zafrullahsyed/cameracapture.git
;protocol=https;tag=v0.1"

S = "${WORKDIR}/git"

inherit pkgconfig cmake

do_install() {
    install -d ${D}${bindir}
    install -m 0755 cameracapture ${D}${bindir}
}

I didn't specify do_install, which caused the errors.

Your inputs helped me very much. Thanks a ton.

Regards,
Zafrullah

You shouldn't need a do_install as cmake install the binary.
