[yocto] Yocto and Google Protocol Buffers

[Giovanni Foiani]

Using EXTRA_OECONF = "--with-protoc=protoc" it builds properly..

My final .bb file is:

*SUMMARY = "Protocol Buffers - Google's data interchange format"*
*DESCRIPTION = "Protocol Buffers are a way of encoding structured data in
an efficient yet extensible format"*
*SECTION = "libs"*
*
*
*DEPENDS = "protobuf-native"*
*DEPENDS_virtclass-native = ""*
*BBCLASSEXTEND = "native"*
*
*
*LICENSE = "LGPLv2.1"*
*#LIC_FILES_CHKSUM =
"file://../protobuf-2.4.1/COPYING.txt;md5=af6809583bfde9a31595a58bb4a24514"*
*LIC_FILES_CHKSUM =
"file://${COMMON_LICENSE_DIR}/LGPL-2.1;md5=1a6d268fd218675ffea8be556788b780"
*
*
*
*PR = "r0"*
*
*
*SRC_URI = "http://protobuf.googlecode.com/files/protobuf-2.4.1.tar.gz"*
*
*
*SRC_URI[md5sum] = "dc84e9912ea768baa1976cb7bbcea7b5"*
*SRC_URI[sha256sum] =
"eac6969b617f397247e805267da2b0db3ff9e5a9163b123503a192fbb5776567"*
*
*
*EXTRA_OECONF = "--with-protoc=protoc"*
*
*
*inherit autotools*
*
*
*
*
*
*
I also built the C binding of Google Protocol Buffer and this is the
recipe.. (I disabled protoc_c creation)

*SUMMARY = "C bindings for Google's Protocol Buffers"*
*DESCRIPTION = "This package provides a code generator and runtime
libraries to use Protocol Buffers from pure C (not C++)."*
*SECTION = "libs"*
*
*
*DEPENDS = "protobuf-c-native"*
*DEPENDS_virtclass-native = ""*
*BBCLASSEXTEND = "native"*
*
*
*DEPENDS += "protobuf"*
*
*
*LICENSE = "LGPLv2.1"*
*LIC_FILES_CHKSUM =
"file://${COMMON_LICENSE_DIR}/LGPL-2.1;md5=1a6d268fd218675ffea8be556788b780"
*
*
*
*PR = "r0"*
*
*
*SRC_URI = "http://protobuf-c.googlecode.com/files/protobuf-c-0.15.tar.gz"*
*
*
*SRC_URI[md5sum] = "73ff0c8df50d2eee75269ad8f8c07dc8"*
*SRC_URI[sha256sum] =
"8fcb538e13a5431c46168fc8f2e6ad2574e2db9b684c0c72b066e24f010a0036"*
*
*
*EXTRA_OECONF = "--disable-protoc"*
*
*
*inherit autotools*
*
