LLVM超出源代码构建：不支持可加载模块（在Linux上） [英] LLVM out of source pass build: Loadable modules not supported (on Linux)

问题描述

我编译和安装LLVM从debian在几个星期前debian wheezy（配置& make），现在试图从源码编译 llvm-mutate pass 。
AFAICC，llvm-mutate遵循cmake 源代码构建说明。

I compiled and installed LLVM from trunk on debian wheezy some weeks ago (configure & make) and now tried to out of source compile the llvm-mutate pass. AFAICC, llvm-mutate follows the cmake out of source pass build instructions.

尝试建立llvm-mutate时

When trying to build llvm-mutate

mkdir build
cd build
cmake -DCMAKE_MODULE_PATH=/usr/local/share/llvm/cmake ../

我得到：

- 忽略Mutate - 此平台不支持可加载模块。

-- Mutate ignored -- Loadable modules not supported on this platform.

hmm？
opt和可加载的传递（在llvm_trunk / build / Debug + Asserts / lib / xxx.so）存在和工作（已使用configure& make，而不是cmake编译）。

hmm? opt and the loadable passes (at llvm_trunk/build/Debug+Asserts/lib/xxx.so) are present and work (have been compiled using configure & make, not cmake).

所以这个问题似乎与cmake有关？
有人遇到这样的问题，在win上使用cygwin：这里

So this problem seems to be related to cmake? Someone else faced such problems, howver on Win using cygwin: here

任何想法？

Any idea? Thx Alex

推荐答案

AddLLVM 模块需要一些先决条件。添加到CMakeLists.txt：

AddLLVM cmake module needs some prerequisites. Add to CMakeLists.txt:

# AddLLVM needs these
set(LLVM_RUNTIME_OUTPUT_INTDIR ${CMAKE_BINARY_DIR}/${CMAKE_CFG_INTDIR}/bin)
set(LLVM_LIBRARY_OUTPUT_INTDIR ${CMAKE_BINARY_DIR}/${CMAKE_CFG_INTDIR}/lib)

include(HandleLLVMOptions) # important: matches compiler flags to LLVM/Clang build
include(AddLLVM)

一些灵感来自此讯息。
