我正在进行跨平台项目(Win 和 Mac)，我需要访问 USB 设备。我找到了完全符合我所有要求的 HIDAPI 库。由于没有用于 HIDAPI 库的 Delphi Firemonkey 包装器(至少我不知道)，所以我正在编写自己的包装器。
HIDAPI 项目网站 http://www.signal11.us/oss/hidapi/说: “在 Windows 上，可以选择将 HIDAPI 内置到 DLL 中。 “
这是真的，因为我已经使用 visual studio 成功编译了源代码并创建了在 Windows 上完美运行的 DLL。现在，因为我不是 C 程序员而且 OSX 不是我最强的技能我想知道是否有可能以及如何从给定的源代码创建 libhidapi.dylib？
最佳答案
也许我遗漏了您的问题...但看起来就在您提供的链接中，您需要为 Linux/Mac 平台编译为 .so 的说明。然后您可以使用来自 Mac 的链接:
编译为 Mac 动态库 (.dylib)。
Build Instructions
...
Mac OS X: Change to the mac/ directory and run make.
To build the Test GUI:
On Linux and Mac, run make from the hidtest/ directory. Make sure to first install fox-toolkit as >described in README.txt
然后 README 本身告诉你构建 mac 有哪些先决条件，以及如何生成最终的共享对象库:
Prerequisites: ---------------Mac:
On Mac, you will need to install Fox-Toolkit if you wish to build the Test GUI. There are two ways to do this, and each has a slight complication. Which method you use depends on your use case.
If you wish to build the Test GUI just for your own testing on your own computer, then the easiest method is to install Fox-Toolkit using ports: sudo port install fox
If you wish to build the TestGUI app bundle to redistribute to others, you will need to install Fox-toolkit from source. This is because the version of fox that gets installed using ports uses the ports X11 libraries which are not compatible with the Apple X11 libraries. If you install Fox with ports and then try to distribute your built app bundle, it will simply fail to run on other systems. To install Fox-Toolkit manually, download the source package from http://www.fox-toolkit.org, extract it, and run the following from within the extracted source: ./configure && make && make install
以及如何生成.so:
Building HIDAPI into a shared library on Unix Platforms:
On Unix-like systems such as Linux, FreeBSD, Mac, and even Windows, using Mingw or Cygwin, the easiest way to build a standard system-installed shared library is to use the GNU Autotools build system. If you checked out the source from the git repository, run the following:
./bootstrap ./configure make make install <----- as root, or using sudo
If you downloaded a source package (ie: if you did not run git clone), you can skip the ./bootstrap step.
./configure can take several arguments which control the build. The two most likely to be used are: --enable-testgui Enable build of the Test GUI. This requires Fox toolkit to be installed. Instructions for installing Fox-Toolkit on each platform are in the Prerequisites section above.
--prefix=/usr Specify where you want the output headers and libraries to be installed. The example above will put the headers in /usr/include and the binaries in /usr/lib. The default is to install into /usr/local which is fine on most systems.
因此您应该能够按照这些说明进行操作，但修改 .dylib 扩展名并添加构建标志:-dynamiclib 和 -fPIC
