Question

我正在使用Sun Studio 12.5开发Solaris 11.3。当我尝试使用Cmake out-of-tree进行配置时，Cmake会完成配置错误并且不会生成makefile。树内也可能被打破。但是我们的程序说建造树外，所以;'我做了什么。

我几乎没有Cmake经验。其他人贡献了CMake文件，我努力完成与它们相关的任务。如果我们的Cmake文件坏了，或者Cmake在Solaris下没有经过良好测试，我不确定我是否做错了什么。

CMake发生了什么，我该如何解决？

以下是Cmake文件的链接。我可以复制/粘贴它们，但它只占用了一大堆空间。这些文件托管在GitHub上，因此它们应始终可用。

在安装3.6.2之前，这是Solaris的Cmake版本：

$ cmake --version
cmake version 2.8.6

以下是Solaris Cmake版本2.8.6。

cryptopp-build$ cmake ../cryptopp

  It fails with the following output:

我从源代码构建了Cmake 3.6.2并安装在/usr/local中以攻击 CXX compiler identification is unknown 问题，但它似乎遇到了一些麻烦。正如我之前所说，我不是Cmake专家（我不确定如何弄乱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的建议清除缓存会导致：

# 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

所以似乎有两个问题。首先是Sun提供的Cmake。将它诊断为“太旧”并没有什么天才。

第二个问题更有趣。 CMake Error: Could not find CMAKE_ROOT !!! 似乎是由sudo make install引起的。一旦我切换到sudo gmake install，问题就会消失。

以下是有关该问题的错误报告：

CMake无法使用Sun Studio 12.5生成Makefile
