如何在介子中为 pango、harfbuzz、glib 等设置 MACOSX_DEPLOYMENT_TARGET
How to set MACOSX_DEPLOYMENT_TARGET in meson for pango, harfbuzz, glib, etc
我正在尝试编译用于 OS X 10.8 及更高版本的库。例如，当我构建 libpng 库时，我正在使用此脚本并且它有效（生成的库与 OS X 10.8 和更新版本兼容）
export MACOSX_DEPLOYMENT_TARGET=10.8
./configure --disable-dependency-tracking --enable-shared
make check
而且有效。
但问题来了。我无法让它适用于任何使用 meson 构建系统的东西。例如 pango:
mkdir build
export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
export MACOSX_DEPLOYMENT_TARGET=10.8
meson -Dintrospection=true -Duse_fontconfig=true --default-library=shared --buildtype=release . build
cd build
ninja
它在 ninja 步失败并出现错误：

如何在配置期间指定 MACOSX_DEPLOYMENT_TARGET？
我找到了解决方案。确切地说，我认为 /usr/local/Cellar/gobject-introspection/1.64.1_2/bin/g-ir-scanner 中存在错误 gobject-introspection。
如果你这样做：
export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
export MACOSX_DEPLOYMENT_TARGET=10.8
export MIN_SUPPORTED_MACOSX_DEPLOYMENT_TARGET=10.8
export LDFLAGS='-mmacosx-version-min=10.8'
export CFLAGS='-stdlib=libc++ -mmacosx-version-min=10.8'
export CXXFLAGS='-stdlib=libc++ -mmacosx-version-min=10.8'
mkdir build
meson -Dintrospection=true -Duse_fontconfig=true --default-library=shared --buildtype=release . build
cd build
ninja
你会得到一个错误。
但是如果您省略 MACOSX_DEPLOYMENT_TARGET 它将毫无问题地工作并且生成的库是为 OS X 10.8 和更新版本构建的。在示例中，我将 unset MACOSX_DEPLOYMENT_TARGET 环境变量：
export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
export MACOSX_DEPLOYMENT_TARGET=10.8
export MIN_SUPPORTED_MACOSX_DEPLOYMENT_TARGET=10.8
export LDFLAGS='-mmacosx-version-min=10.8'
export CFLAGS='-stdlib=libc++ -mmacosx-version-min=10.8'
export CXXFLAGS='-stdlib=libc++ -mmacosx-version-min=10.8'
#unset MACOSX_DEPLOYMENT_TARGET env variable which broke the build before
unset MACOSX_DEPLOYMENT_TARGET
mkdir build
meson -Dintrospection=true -Duse_fontconfig=true --default-library=shared --buildtype=release . build
cd build
ninja
现在可以使用了
