gRPC C++ on Yocto 2.2
问题
我正在尝试在Yocto 2.2上为armv5e构建gRPC。我使用的是gRPC 1.6.8，但在进行do_compile时遇到了错误。以下是我用于gRPC的配方：
inherit autotools-brokensep pkgconfig
DEPENDS = "\
protobuf3 \
protobuf3-native \
zlib \
openssl \
c-ares \
";
SRC_URI = "gitsm://github.com/grpc/grpc.git;branch=v1.6.x"
SRCREV = "4735689cc5af6c56eeae5c9ab10fa538552dc08e"
DEPENDS_append_class-target = " gtest grpc-native "
DEPENDS_append_class-nativesdk = " grpc-native"
SRC_URI_append_class-target = " file://0001-CMakeLists.txt-Fix-grpc_cpp_plugin-path-during-cross.patch"
PR = "r0"
S = "${WORKDIR}/git"
# 修复静态库生成
AR += "rcs"
OUTDIR = "${S}/libs/opt/"
CXXFLAGS_append_class-native = " --with-protoc=protoc,--host=x86_64-linux,CC=\"${CC}\",CXX=\"${CC}\",HOST_CC=\"gcc-6\",HOST_CXX=\"gcc-6\",RANLIB=\"${CC}\",LD=\"${CC}\",LDXX=\"${CC}\""
do_configure () {
}
do_compile () {
make clean
export LD="${CC}"
export GRPC_CROSS_COMPILE=true
export HAS_PKG_CONFIG=false
make prefix=${exec_prefix} static_cxx shared_cxx
# make shared_cxx static_cxx
}
do_install () {
oe_runmake prefix=${D}${exec_prefix} install-headers_c
oe_libinstall -C ${OUTDIR} -so libgpr ${D}${libdir}
oe_libinstall -C ${OUTDIR} -so libgrpc ${D}${libdir}

oe_libinstall -C ${OUTDIR} -so libgrpc++_unsecure ${D}${libdir}
install -d ${D}${libdir}/pkgconfig
install -m 0644 ${OUTDIR}/pkgconfig/*.pc ${D}${libdir}/pkgconfig/
}
INSANE_SKIP_${PN} = "already-stripped rpaths"
我收到以下错误信息：
| /usr/bin/ld: /home/src/build/tmp/work/armv5e-linux-gnueabi/grpc/1.6.8-r0/git/objs/opt/src/compiler/cpp_plugin.o: Relocations in generic ELF (EM: 40)

| make: *** [/home/src/build/tmp/work/armv5e-polatis-gnueabi/grpc/1.6.8-r0/git/bins/opt/grpc_cpp_plugin] Error 1
我正在使用此Makefile
当我尝试构建static_c和shared_c目标时，构建是成功的。但是当我尝试构建static_cxx和shared_cxx时，会出现错误。请帮助解决。

Im using this Makefile
I have tried building fr static_c and shared_c targets and build is successful. When i try for static_cxx and shared_cxx it gives the error. Please help

问题实际上出现在交叉编译过程中。源代码使用32位编译器编译，但尝试使用主机64位链接器进行链接。通过更改 EXTRA_OEMAKE_append_class-target 来修复。
英文:
It was actually problem during cross-compilation. The source was compiled using 32 bits compiler but it was trying to link using host 64 bit linker. Fixed by changing the linker through EXTRA_OEMAKE_append_class-target.
