<pre>When I tried to upgrade llvm 3.6 to llvm 3.7 in my project I encountered an
error on travis ci OSX build:
CMake Error at
/usr/local/opt/llvm37/lib/llvm-3.7/share/llvm/cmake/LLVMConfig.cmake:54
(include):
include could not find load file:
/LLVMExports.cmake
After some investigations i found that LLVMConfig.cmake file is at fault.
Look at this:
# Compute the CMake directory from the LLVMConfig.cmake file location.n
get_filename_component(_LLVM_CMAKE_DIR "${CMAKE_CURRENT_LIST_FILE}" PATH)n #
Compute the installation prefix from the LLVMConfig.cmake file location.n
get_filename_component(LLVM_INSTALL_PREFIX "${CMAKE_CURRENT_LIST_FILE}" PATH)n
get_filename_component(LLVM_INSTALL_PREFIX "${LLVM_INSTALL_PREFIX}" PATH)n
get_filename_component(LLVM_INSTALL_PREFIX "${LLVM_INSTALL_PREFIX}" PATH)n
get_filename_component(LLVM_INSTALL_PREFIX "${LLVM_INSTALL_PREFIX}" PATH)n
set(_LLVM_LIBRARY_DIR "${LLVM_INSTALL_PREFIX}/lib")
You can see that for some reason newlines ('\n') became just 'n', so it's all
became part of the comment therefore needed vars weren't set.
If I build llvm using cmake it generates correct file. The problem occures only
with autotools build. Tested on travis with:
...
script:
- ../configure --enable-optimized --disable-bindings --enable-targets=host
--enable-shared --enable-libffi
- make -j4
...</pre>
