CMake无法使用SunStudio12.5生成Makefile

Question

我正在使用Sun Studio 12.5开发Solaris 11.3。当我尝试使用Cmake -out-tree进行配置时，Cmake会以配置错误完成，而不会生成makefile。树内也可能会被打破。但是我们的程序说要建一棵树，这样我就能做什么。

我几乎没有Cmake的经验。其他人贡献了CMake文件，我很难处理与它们相关的任务。我不确定我是否做错了什么，我们的Cmake文件是否被破坏了，或者Cmake是否在Solaris下没有很好的测试。

CMake是怎么回事，我该如何解决呢？

以下是Cmake文件的链接。我可以复制/粘贴它们，但它只占了一堆空间。这些文件托管在GitHub上，因此它们应该总是可用的。

• CMakefileList.txt
• cryptopp-config.cmake

以下是Solaris的Cmake版本，在我安装3.6.2之前：

$ cmake --version
cmake version 2.8.6

下面来自Solaris Cmake版本2.8.6。

cryptopp-build$ cmake ../cryptopp

CMake Error at /usr/share/cmake-2.8/Modules/CMakeTestCXXCompiler.cmake:45 (MESSAGE):

  It fails with the following output:

和：

$ /opt/developerstudio12.5/bin/CC -V

我从源代码中构建了Cmake3.6.2，并安装在/usr/local中以解决CXX compiler identification is unknown问题，但它似乎有一些问题。正如我前面所说的，我不是一个Cmake专家(我也不知道如何才能搞砸一个make && sudo make install)。

cryptopp-build$ cmake ../cryptopp
CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
Modules directory not found in
/usr/local/bin
CMake Error: Error executing cmake::LoadCache(). Aborting.

按照@AndrewHenle的建议清除缓存，结果是：

# The project GNUmakefile clears all Cmake artifacts because Cmake cannot seem to do it on its own
$ cd cryptopp
$ git status -s
$

$ cd ..
$ rm -rf cryptopp-build
$ mkdir cryptopp-build
$ cd cryptopp-build

# Using 3.6.2 now
$ cmake ../cryptopp
CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
Modules directory not found in
/usr/local/bin
CMake Error: Error executing cmake::LoadCache(). Aborting.

Answer 1

所以出现了两个问题。首先是向下的Sun提供的Cmake。把它诊断为“太老”一点也不天才。

第二个问题更有趣。看来CMake Error: Could not find CMAKE_ROOT !!!是由sudo make install引起的，当我切换到sudo gmake install时，问题就消失了。

以下是有关此问题的bug报告：

• Cmake问题16302: Cmake无法识别SunStudio12.5编译器
• Cmake问题16303: Cmake未能在Solaris 11.3上生成工作安装
