<pre>I'm building on Solaris 10 / sparcv9, though I suspect this isn't solaris or
sparc specific.
I built with the following:
cmake ../src/llvm \
-DCMAKE_C_COMPILER=gcc-7.2.0 \
-DCMAKE_CXX_COMPILER=g++-7.2.0 \
-DGCC_INSTALL_PREFIX=$(dirname $(dirname $(which gcc-7.2.0))) \
-DBUILD_SHARED_LIBS=ON \
-DLINK_LLVM_DYLIB=ON \
-DCMAKE_BUILD_TYPE=RelWithDebInfo
make -j32
I'll explain why I built using those options in a separate comment.
When linking libLTO.so it fails with undefined references to the following:
LLVMDisasmDispose
LLVMCreateDisasmCPU
LLVMCreateDisasm
LLVMDisasmInstruction
LLVMSetDisasmOptions
If I remove those entries from tools/lto/lto.exports then it links fine.</pre>
