windows - 使用 GCC-4.9.1_x64 编译 Clang 时命令语法不正确

Question

在 Windows 系统上遇到一些关于 cmake 和 gcc-4.9.1 的问题，并花了 2 个多小时用 clang 构建 llvm 之后，我遇到了一个非常好的错误，我似乎找不到相关信息。我已根据文档完成所有操作，这里是 make 给我的讲故事的错误消息:

Scanning dependencies of target LTO_exports
[ 69%] Creating export file for LTO
The syntax of the command is incorrect.
make[2]: *** [tools/lto/LTO.def] Error 1
make[1]: *** [tools/lto/CMakeFiles/LTO_exports.dir/all] Error 2
make: *** [all] Error 2

仅此而已，没有其他详细信息。我检查了 LTO.def 文件，因为它引用了它。该文件包含一个条目:“EXPORTS[CR][LF]”。 LTO_exports.dir/all 包含以下文件:

build.make
cmake_clean.cmake
depend.internal
depend.make
DependInfo.cmake
progress.make

我根本没有碰过这些文件。在实际使用 make 之前，我使用了以下 cmake 命令。

C:\LLVM_Binaries>cmake -G"MinGW Makefiles" -DCMAKE_C_COMPILER="C:/MinGW/bin/gcc.exe" -DCMAKE_CXX_COMPILER="C:/MinGW/bin/g++.exe" -DCMAKE_MAKE_PROGRAM="C:/MinGW/bin/make.exe" -DCMAKE_BUILD_TYPE=Release ..\LLVM

这里还有 gcc g++ 和 make 的详细信息:gcc --版本

还有其他人遇到过这个问题并设法在 64 位 Windows 操作系统上使用 clang 构建 llvm 吗？

@Edit(make VERBOSE=1 的输出)

Answer 1

在深入研究这个问题后，我成功地构建了它。对于在 Windows 上使用 gcc 编译 llvm&clang 时可能遇到此错误的任何人:http://reviews.llvm.org/D5476#5e5fbd1d当然，您可以通过使用来自他们 SVN 的源代码而不是从 http://llvm.org/releases/download.html#3.5 下载最新的稳定版本来避免这个问题。
