我认为在静态库中构建更容易,因为共享需要添加“-fpic”。
对于我的项目(在 Linux 下),我使用此脚本构建了一个静态 node.js 库:
#!/bin/sh
# This script is LGPL feel free to use it!
if test ! "$#" = "1"; then
echo "Run with the archive in parameter:"
echo "\t${0} ./node-v0.XX.XX.tar.gz"
echo "\nIt will build a ./libnode_static.a in current dir"
return
fi
HERE=$PWD
#Extract Tarball
tar xf $1 | exit 1
DIRNAME=`echo $1 | sed s/.tar.gz//g`
cd $DIRNAME
#Patch node.gyp to build in static
sed -i "s/'type': 'executable',/'type': 'static_library',/g" ./node.gyp
#Patch node_main.cc to rename the main in node_main
sed -i "s/int main(/int node_main(/g" ./src/node_main.cc
#Build Node.js
./configure
make -j8
#Move to build directory
cd ./out/Release
#Extract .a
#Cleanup if previous build
rm -fr *.tmpd
echo "== Extracting *.a =="
#Make sure we create a directory
#for each.a as some .o might
#have the same name
for a in `ls *.a`
do
echo "\t${a}..."
mkdir "$a.tmpd"
cd "$a.tmpd"
ar x ../$a
cd ..
done
#Repack in a single .a
find . -iname "*.o" | xargs ar rcs libnode_static.a
#Cleanup
rm -fr *.tmpd
echo "== DONE =="
#Move in start directory
mv ./libnode_static.a ${HERE}/
cd ${HERE}
#Sanity CHECK
echo "== Performing Sanity Check =="
TMP_FILE=`mktemp /tmp/XXXXXX.cxx`
TMP_EXE=`mktemp /tmp/XXXXXX`
cat << . > ${TMP_FILE}
int node_main( int argc, char **argv);
int main(int argc, char ** argv )
{
node_main( argc, argv );
return 0;
}
.
#Try compiling
g++ ${TMP_FILE} -o ${TMP_EXE} -lnode_static -ldl -pthread -L.
#Try running
RET=`${TMP_EXE} -e "console.log('okfromnode')"`
if test "x${RET}" = "xokfromnode"; then
echo "== Sanity check OK =="
else
echo "== Sanity check FAILED =="
exit 1
fi
rm ${TMP_FILE} ${TMP_EXE}
echo "== Node.js is now built statically in ./libnode_static.a =="
exit 0
运行如下:
sh script.sh node-v0.10.XX.tar.gz
如果一切顺利,您应该在当前目录中获得一个 libnode_static.a。
将它与这样的代码一起使用:
int node_main( int argc, char **argv);
int main(int argc, char ** argv )
{
/* Here we spawn a node.js instance */
return node_main( argc, argv );
}
然后像这样编译:
g++ ./test.cxx -o ./my_node -lnode_static -ldl -pthread -L.
你已经嵌入了节点:
./my_node -e "console.log('Hello World')"
#Outputs
Hello World
希望这会有所帮助。
