我使用这个项目为 iOS 构建提升：https ://github.com/danoli3/ofxiOSBoost/blob/master/scripts/build-libc%2B%2B

我的客户项目设置为：

IPHONEOS_DEPLOYMENT_TARGET = 7.0
Base SDK = 9.2

当我链接到 boost 框架时，我收到以下警告。

ld: warning: object file ((error_code.o)) was built for newer iOS version (9.2) than being linked (7.0)
ld: warning: object file ((future.o)) was built for newer iOS version (9.2) than being linked (7.0)
ld: warning: object file ((once.o)) was built for newer iOS version (9.2) than being linked (7.0)
ld: warning: object file ((thread.o)) was built for newer iOS version (9.2) than being linked (7.0)

如何更改 boost bjam 的部署目标？或者有没有办法解决这些警告？

在您引用的脚本中像这样将标志“-miphoneos-version-min=7.0”添加到 user-config.jam。

updateBoost()
{
echo Updating boost into $BOOST_SRC...

cp $BOOST_SRC/tools/build/example/user-config.jam $BOOST_SRC/tools/build/example/user-config.jam.bk

cat >> $BOOST_SRC/tools/build/example/user-config.jam <<EOF
