package/llvm: set the path to llvm-config

2019-01-17T08:56:49+00:00

While building llvm for the target (x86_64), the build failed due to path poisoning (-I/usr/include/libxml2) while building NATIVE tools (i.e for the host). The llvm package tries to build a tool for the host with the cross-compiler which doesn't work when the paranoid toolchain wrapper (BR2_COMPILER_PARANOID_UNSAFE_PATH) is enabled. We know that llvm (target) needs llvm-tablegen and llvm-config built by host-llvm, but only LLVM_TABLEGEN is provided by llvm.mk. Adding LLVM_CONFIG_PATH=$(HOST_DIR)/bin/llvm-config for llvm (target) fixes the path poisoining issue since llvm doesn't build the NATIVE variant.

package/llvm: remove $ORIGIN/../lib from RPATH

2018-04-12T19:12:51+00:00

AddLLVM.cmake adds $ORIGIN/../lib to the RPATH of llvm binaries. This causes a problem when llvm-config built for the host, installed in STAGING_DIR, is executed under the following conditions: * Target architecture same as host architecture (normally x86_64) * Target's libc different from host's libc (normally glibc) llvm-config will try to link with the target's libc, resulting in: ./llvm-config: error while loading shared libraries: libc.so.0: cannot open shared object file: No such file or directory. To avoid this, we simply add pass -DCMAKE_INSTALL_RPATH="$(HOST_DIR)/lib" in HOST_LLVM_CONF_OPTS.
