February 24, 2015 basic question about building ldc/calypso from source | ||||
---|---|---|---|---|
| ||||
Hi. I am struggling with using cmake to build LDC. I have successfully built LLVM and clang following standard instructions, but I am not so familiar with cmake and do not know which directory LLVM_ROOT_DIR should point to. Ultimately I would like to build calypso, but I have the same problem with stock LDC. Running arch linux on a 64 bit machine. I have tried various iterations of pointing to build directory as well as llvm parent. [laeeth@console build]$ cmake .. -DLLVM_ROOT_DIR='../../llvm' -DCMAKE_BUILD_TYPE=Release [laeeth@console build]$ ls ../../llvm/ autoconf configure LLVMBuild.txt README.txt bin CREDITS.TXT llvm.spec.in test bindings docs Makefile tools build examples Makefile.common unittests cmake include Makefile.config.in utils CMakeLists.txt lib Makefile.rules CODE_OWNERS.TXT LICENSE.TXT projects [laeeth@console build]$ This is the error I receive: [laeeth@console build]$ cmake .. -DLLVM_ROOT_DIR='../../llvm' -DCMAKE_BUILD_TYPE=Release CMake Error at cmake/Modules/FindLLVM.cmake:140 (string): string sub-command REGEX, mode MATCHALL needs at least 5 arguments total to command.

I have successfully built LLVM and clang following standard instructions, but I am not so familiar with cmake and do not know which directory LLVM_ROOT_DIR should point to. I think LLVM_ROOT_DIR has to be an absolute path. When I use a prebuild llvm, it get it to work like this: cmake -DLLVM_ROOT_DIR=/opt/local/libexec/llvm-3.4/ ... or when I use a llvm I built, say configured with --enable-optimized and --disable-assertions then I do something like (assume I built llvm in dir build-llvm): cmake -DLLVM_ROOT_DIR=/Users/dan/projects/build-llvm/Release/ ... |

All ldc's dependencies are available through pacman. What does `which llvm-config` give you? I just tested this with ldc on arch: git clone https://github.com/ldc-developers/ldc cd ldc git submodule update --init mkdir build cd build cmake ../ make -j8 everything worked fine. |

Hmm, I tried pretty much the same command and it worked for me. I did notice that the command output listed the llvm directory as /usr, regardless of where my local llvm is, so maybe it also depends on the system llvm being installed? It shows the actual LLVM_ROOT_DIR in the generated CMakeCache.txt set to the right local directory, so maybe try installing the system llvm also and see if it makes a difference?

It is the output of llvm-config --prefix. If you have LLVM installed then there is no need to specify LLVM_ROOT_DIR. As an alternative you can add $(llvm-config --prefix)/bin to your PATH variable. > > This is the error I receive: > > [laeeth@console build]$ cmake .. -DLLVM_ROOT_DIR='../../llvm' -DCMAKE_BUILD_TYPE=Release > CMake Error at cmake/Modules/FindLLVM.cmake:140 (string): > string sub-command REGEX, mode MATCHALL needs at least 5 arguments total to > command. > Call Stack (most recent call first): > cmake/Modules/FindLLVM.cmake:174 (llvm_set_libs) > CMakeLists.txt:18 (find_package) > > > CMake Error at /usr/share/cmake-3.1/Modules/FindPackageHandleStandardArgs.cmake:138 (message): > Could NOT find LLVM: Found unsuitable version "", but required is at least > "3.1" (found ) > Call Stack (most recent call first): > /usr/share/cmake-3.1/Modules/FindPackageHandleStandardArgs.cmake:372 (_FPHSA_FAILURE_MESSAGE) > cmake/Modules/FindLLVM.cmake:196 (find_package_handle_standard_args) > CMakeLists.txt:18 (find_package) > > > -- Configuring incomplete, errors occurred! > See also "/btrfs0/dlang/calypso/calypso/build/CMakeFiles/CMakeOutput.log". Which version of LLVM and LDC do you use? The error message looks like your using a recent LLVM with an old LDC version.... Regards, Kai |

Hi Laeeth,
Didn't you get LLVM_ROOT_DIR mixed up with LLVM_SOURCE_PATH added for Calypso and which has to point to a LLVM + Clang source tree?

Thank you for the generous help. I am not able to use a computer properly at moment, but hope to resume shortly.

Yes - you were spot on. Diminishing marginal returns to working without a break. Thanks for the help.
