基本上inherit cmake跟inherit autotools是差不多的，其實cmake class裡面也是有inherit autotool，比較大的差異是，source file在cmake下是放在${PN}目錄下，即package name下，檔案結構如下：
brook@vista:~/oe-core$ tree meta/recipes-support/brook-cmake
meta/recipes-support/brook-cmake
|-- brook-cmake
| `-- brook-cmake.patch
`-- brook-cmake_1.0.bb
1 directory, 2 files
brook-cmake.patch就是放置CMakeLists.txt、main.c跟LICENSE，其內容如下：
CMakeLists.txt
cmake_minimum_required (VERSION 2.6) project(brook-cmake-demo) add_executable(brook-cmake main.c) install(TARGETS brook-cmake DESTINATION bin)
main.c
#include <stdio.h> int main(int argc, char *argv[]) { printf("hello, cmake\n"); return 0; }
brook-cmake_1.0.bb
DESCRIPTION = "Brook CMake Project" LICENSE = "GPLv2" LIC_FILES_CHKSUM = "file://LICENSE;md5=5ff2bd2dd80c7cc542a6b8de3ee4ff87" SRC_URI = "file://brook-cmake.patch \ " inherit cmake EXTRA_OEMAKE = "-Wall"
下面這裡是多個版本的寫法
其實寫法都一樣，只是patch file的目錄要包含版本號，檔案結構如下：brook@vista:~/oe-core/meta/recipes-support$ tree brook-cmake brook-cmake |-- brook-cmake-1.0 | `-- brook-cmake.patch |-- brook-cmake-2.0 | `-- brook-cmake.patch |-- brook-cmake_1.0.bb `-- brook-cmake_2.0.bb
BB檔與patch的內容跟上面都是一樣的
brook@vista:~/oe-core$ cat meta/recipes-support/brook-cmake/brook-cmake_1.0.bb DESCRIPTION = "Brook CMake Project" LICENSE = "GPLv2" LIC_FILES_CHKSUM = "file://LICENSE;md5=7e4bf6f59b6da8e57ed5425a10a7310b" SRC_URI = "file://brook-cmake.patch \ " inherit cmake BBCLASSEXTEND = "native" EXTRA_OEMAKE = "-Wall" brook@vista:~/oe-core$ cat meta/recipes-support/brook-cmake/brook-cmake_2.0.bb DESCRIPTION = "Brook CMake Project" LICENSE = "GPLv2" LIC_FILES_CHKSUM = "file://LICENSE;md5=7e4bf6f59b6da8e57ed5425a10a7310b" SRC_URI = "file://brook-cmake.patch \ " inherit cmake BBCLASSEXTEND = "native" EXTRA_OEMAKE = "-Wall"

如果沒有特別指定版本的話，會使用最新的，可以透過設定PREFERRED_VERSION_package_name設定特定版本，如
brook@vista:~/oe-core$ grep -H PREFERRED_VERSION build/conf/local.conf build/conf/local.conf:PREFERRED_VERSION_brook-cmake = "1.0"相關資訊可以參考Bitbake User Manual/2.3. Preferences and Providers

SRC_URI variable: Source code and patches
回覆刪除file: for patches and additional files
Supported options:
patch
Used as "patch=1" to define this file as a patch file. Patch files will be copied to ${S}/patches and then applied to source from within the source directory, ${S}.
pnum
By default patches are applied with the "-p 1" parameter, which strips off the first directory of the pathname in the patches. This option is used to explicitly control the value passed to "-p". The most typical use is when the patches are relative to the source directory already and need to be applied using "-p 0", in which case the "pnum=0" option is supplied.
