QNX7.1 交叉编译开源库

1.下载QNX7.1 SDK并解压

ITL:~/work/tiqnx710$ ls -l

2.编译protobuf-c-test
cd protobuf-c-test
mkdir out
cd …
sudo apt install autoconf libtool
source …/…/tiqnx710/qnxsdp-env.sh
./autogen.sh
在这里插入图片描述
make -j8
make install

zlog编译类型步骤：
zlog
git clone http://xxxx/zlog.git
cd zlog
git checkout tag-1.2.15
./autogen.sh
./configure --prefix=/home/xxxx/zlog/out --host=aarch64-unknown-nto-qnx CC=aarch64-unknown-nto-qnx7.1.0-gcc CFLAGS=‘-D_QNX_SOURCE -D__linux__’
make -j1
make install
zlog 可能遇到一个编译错误：
“CE -D__linux__ -c event.c -fPIC -shared -DPIC -o .libs/libzlog_la-event.o
event.c:23:10: fatal error: sys/syscall.h: No such file or directory
#include <sys/syscall.h>
^~~~~~~~~~~~~~~
compilation terminated.
Makefile:536: recipe for target ‘libzlog_la-event.lo’ failed
”
解决方法：
“diff --git a/src/event.c b/src/event.c

修改即可编译通过

1.json-c 交叉编译
cd json-c
mkdir out
source …/…/tiqnx710/qnxsdp-env.sh
cmake -DCMAKE_SYSTEM_NAME=“QNX” -DCMAKE_SYSTEM_PROCESSOR=“aarch64” -DCMAKE_CXX_COMPILER_ID=“GNU”
-DCMAKE_C_COMPILER=“aarch64-unknown-nto-qnx7.1.0-gcc”
-DCMAKE_CXX_COMPILER=“aarch64-unknown-nto-qnx7.1.0-g++”
-DCMAKE_BUILD_TYPE=“Debug”
-DCMAKE_FIND_ROOT_PATH=“/home/xxx/tiqnx710/target/qnx7”
-DCMAKE_INSTALL_PREFIX=/home/xxxx/json-c/out
-DCMAKE_PREFIX_PATH=/home/xxxx/json-c/out
make -j8
make install
2.查看编译产物

libzip交叉编译类似，按照如下步骤即可：
libzip
git clone http://xxxx/libzip.git
cd libzip
source /homexxxx/tiqnx710/qnxsdp-env.sh
cmake -DCMAKE_SYSTEM_NAME=“QNX” -DCMAKE_SYSTEM_PROCESSOR=“aarch64” -DCMAKE_C_FLAGS=“-fPIC -fvisibility=hidden” -DCMAKE_CXX_COMPILER_ID=“GNU” -DCMAKE_C_COMPILER=“aarch64-unknown-nto-qnx7.1.0-gcc” -DCMAKE_CXX_COMPILER=“aarch64-unknown-nto-qnx7.1.0-g++” -DCMAKE_BUILD_TYPE=“Debug” -DCMAKE_FIND_ROOT_PATH=“/xxxx/qnx710/tiqnx710/target/qnx7/aarch64le” -DCMAKE_INSTALL_PREFIX=/home/xxxlibzip/out -DCMAKE_PREFIX_PATH=/home/xxxx/libzip/out
make -j1
make install
