Hi, I tried to compile TVM with bazel, but block in src/target/llvm. Here is my TVM bazel BUILD file
cc_library(
name = "llvm_compiler",
srcs = glob([
"src/target/llvm/*.cc",
]),
hdrs = glob([
"src/target/llvm/*.h",
"src/target/*.h",
]),
deps = [
"//3rdparty/clang+llvm-9.0.0-x86_64-linux-gnu-ubuntu-16.04:llvm",
":compiler_hdrs",
":runtime_hdrs",
":arith_hdrs",
":implicit_hdrs",
":tir_hdrs",
],
copts = [
"-DTVM_LLVM_VERSION=90",
"-O0",
],
# alwayslink = True,
linkstatic = True,
visibility = ["//visibility:public"])
And I add this file into clang+llvm-9.0.0-x86_64-linux-gnu-ubuntu-16.04.tar.gz which download from web

When I run this libtvm.so, it complain that:
TVMError: Check failed: bf != nullptr: target.build.llvm is not enabled
So I change llvm_compiler as alwayslink=true, but it complain
OSError: lib/libtvm.so: undefined symbol: _ZTIN4llvm6legacy11PassManagerE
And I tried this thread: Building LLVM with Bazel - Stack Overflow, with code : https://github.com/dgp1130/llvm-bazel-foolang, but the error reported is same.
Everything works fine on CMake, I don’t know what’s different with Bazel. And actually, I only hope “TVM_REGISTER_GLOBAL(“target.build.llvm”)” not delelte by gcc.
Thanks!
