如何启用cmake从安装排除子目录？ [英] How to enable cmake to exclude a subdirectory from install?

问题描述

我一直在尝试在RHEL 6.4框上为 libc ++ 3.3创建 RPM 我需要静态和共享库。所以，我学习了一些 cmake 的基础知识，然后修改了捆绑的 CMakeList.txt 。

I have been trying to build RPM packages for libc++ 3.3 on a RHEL 6.4 box. I need both static and shared libraries. So, I learned some basics of cmake and then modified the bundled CMakeList.txt. Got that part to work.

但是由于在RHEL 6.x中，所有64位库都应该转到 / usr / lib64 而不是 / usr / lib ，我一直在尝试使用下面的工作完成：

But since in RHEL 6.x, all 64-bit libraries should go to /usr/lib64 instead of /usr/lib, I have been attempting to use the following to get the job done:

（A）在建立期间，我使用

(A) During building, I use

SET(LIBRARY_OUTPUT_PATH ${PROJECT_BINARY_DIR}/lib${LIB_SUFFIX})

以拥有所有库文件（ * .so * ，而不是 lib >。

to have all library files (*.so* and *.a) located in lib64 rather than lib.

（B）使用 ADD_LIBRARY ... 命令，如下所示

(B) Using a ADD_LIBRARY... command as shown below

ADD_LIBRARY(c++ STATIC ...

和

set_target_properties(c++ PROPERTIES
   ARCHIVE_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/lib${LIB_SUFFIX})
   INSTALL(TARGETS c++ 
         ARCHIVE DESTINATION lib${LIB_SUFFIX})

静态库安装在 / usr / lib64 中。

（C）此外，使用

INSTALL(FILES ${PROJECT_BINARY_DIR}/lib${LIB_SUFFIX}/libc++.so DESTINATION lib${LIB_SUFFIX})
INSTALL(FILES ${PROJECT_BINARY_DIR}/lib${LIB_SUFFIX}/libc++.so.1 DESTINATION lib${LIB_SUFFIX})
INSTALL(FILES ${PROJECT_BINARY_DIR}/lib${LIB_SUFFIX}/libc++.so.1.0 DESTINATION lib${LIB_SUFFIX})

也要在 / usr / lib64 中安装共享库。

但共享库的副本仍然安装在生成的RPM中的 / usr / lib 中。如何防止它？

But a copy of the shared library is still installed in /usr/lib in the resulting RPM. How can I prevent it?

如果我要写一个RPM spec 文件， _libdir 宏自动处理这个。使用 cmake ，鉴于我还是新的，我将欣赏一个关于使用正确指令的提示/指针。

If I were to write a RPM spec file, the _libdir macro automatically handles this. With cmake, given the fact that I am still new to it, I would appreciate a hint/pointer as to the right directive to use.

推荐答案

实际上，在 cmake 邮件列表中有帮助的人，我现在可以摆脱在 spec 文件中创建％dir / usr / lib 它实际上很简单：只需cd到 $ CMAKE_SOURCE_DIR / lib 并编辑 CMakeLists.txt 。将 $ {LIB_SUFFIX} 附加到两个安装 DESTINATION 。重新生成 build 子目录中的 Makefile ，然后重新生成 make& make package 。所有库文件根据需要进入 / usr / lib64 。

Actually, with a helpful person in the cmake mailing list, I am now able to rid of the %dir /usr/lib in the generated spec file. It's actually quite simple: just cd to $CMAKE_SOURCE_DIR/lib and edit the CMakeLists.txt there. Append ${LIB_SUFFIX} to the two install DESTINATIONs. Regenerate the Makefile in the build subdirectory, and then make && make package. All library files go into /usr/lib64 as desired.
