我想为Windows交叉编译glib。 configure抛出此错误：
configure：警告：使用不带主机三元组前缀的交叉工具 configure：error：未满足包要求（libffi＆gt; = 3.0.0）：
找不到包'libffi'
如果您正在考虑调整PKG_CONFIG_PATH环境变量 以非标准前缀安装软件。
或者，您可以设置环境变量LIBFFI_CFLAGS 和LIBFFI_LIBS，以避免需要调用pkg-config。 有关更多详细信息，请参见pkg-config手册页。
然而pkg-config --modversion libffi打印“3.1”。我已经从debian jessie存储库安装了libffi和libffi-dev。
（我不确定这是否属于超级用户，因为它也与包问题有关）

[System.Runtime.InteropServices.DllImport("User32.dll")]
static extern bool MoveWindow(IntPtr h, int x, int y, int width, int height, bool redraw);
private void toolTip1_Draw(object sender, DrawToolTipEventArgs e)
{
e.DrawBackground();
e.DrawBorder();
e.DrawText();
var t = (ToolTip)sender;
var h = t.GetType().GetProperty("Handle",
System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
var handle = (IntPtr)h.GetValue(t);
var c = e.AssociatedControl;
var location = c.Parent.PointToScreen(new Point(c.Right - e.Bounds.Width, c.Bottom));
MoveWindow(handle, location.X, location.Y, e.Bounds.Width, e.Bounds.Height, false);
}

export LIBFFI_CFLAGS='-I /mingw/lib/libffi-VERSION/include'
VERSION is to be replaced with whatever version you built above.
For me VERSION is 3.0.10.
export LIBFFI_LIBS=-lffi
export lt_cv_deplibs_check_method="pass_all"
export CFLAGS=”O0 -g -pipe -Wall -march=i486 -mms-bitfields -mthreads”
export CPPFLAGS=”-DG_ATOMIC_OP_USE_GCC_BUILTINS=1”
export LDFLAGS=”-Wl,--enable-auto-image-base”
../configure --prefix=/mingw --with-pcre=internal --disable-static --disable-gtk-doc --enable-silent-rules
make
make install
。pkg_config可以正常重建，如下所示：glib答案 1 :(得分：0)
就我而言，运行npm i时，我收到了下一条错误消息：
node-gyp rebuild
Package libffi was not found in the pkg-config search path.
Perhaps you should add the directory containing `libffi.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libffi', required by 'gobject-2.0', not found
gyp: Call to 'pkg-config --cflags cairo poppler-qt5' returned exit status 1 while in binding.gyp. while trying to load binding.gyp
我发现问题出在导出PATH上
所以我跑了brew reinstall -s poppler
在安装结束时，您可以运行路径的导出
If you need to have qt first in your PATH run:
echo 'export PATH="/usr/local/opt/qt/bin:$PATH"' >> ~/.zshrc
For compilers to find qt you may need to set:
export LDFLAGS="-L/usr/local/opt/qt/lib"
export CPPFLAGS="-I/usr/local/opt/qt/include"
For pkg-config to find qt you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/qt/lib/pkgconfig"
这为我解决了。
我希望对您有所帮助。
