Cmake with bitbake recipe

Question

I am trying to build an yocto image with my own package. I have OpenCV code on github which uses cmake.

I trying to write a recipe for it and facing lot of errors. Can any one give some hints on what functions or parameters to include in my recipe. My recipe looks as following

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

I followed these tutorials to write my recipe with cmake but in vain: Bitbake Player recipe

Cmake-Bitbake-QT

Could you please mention the errors? – László Papp Aug 23 '13 at 20:48 — László Papp, Aug 23 '13 at 20:48
Also, you should not use PR anymore. – László Papp Aug 23 '13 at 21:26 — László Papp, Aug 23 '13 at 21:26

The correct way of writing own recipes with cmake as follows:

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}
}

Previously I didn't add do_install that's the reason yocto downloads the recipe but unable to include it Image.

do_install is not necessary, see elmsfu's answer – Anonymous Aug 10 '15 at 07:06

Like the previous comment, `do_install` isn't necessary. The `cmake.bbclass` will run ` oe_runmake 'DESTDIR=${D}' install` by default. – Anders Apr 26 '16 at 06:55

If the CMakeLists.txt uses the install command then bitbake will do the install for you and you won't need to define you own do_install.

install(TARGETS cameracapture DESTINATION bin)

do you means there is no need to add `do_install()` in the recipe? – hukeping Jul 29 '19 at 08:49
@hukeping You don't have to add do_install() task. install instruction as pointed in answer has to be added in CMakeLists.txt. do_install() from cmake base class will make use of "make install". – chandola Jan 02 '21 at 12:40

add the source directory in your recipe.

example S = "${WORKDIR}/cameracapture

S is the source code path where your CMakeList.txt.

any how your are inheriting the cmake bbclass in your recipe, so it will take care of all configure , compile and install functionalities.

after doing this you can remove you do_configure function in the above recipe also.

you can add your make options if any to the below macro (as you kept empty). example

EXTRA_OECMAKE = "all"
