couldn't process IR file: LLVMParseIRInContext failed #315

Closed luoffei closed 2 years ago

luoffei commented 2 years ago

I follow the example tutorial, when I run cargo bpf build --target-dir=../target I get the following error

   Compiling probes v0.1.0 (/mnt/c/files/dev/rust/redbpf-tutorial/probes)
warning: due to multiple output types requested, the explicitly specified output file name will be adapted for each output type

warning: ignoring --out-dir flag due to -o flag

I switched the rust version to 1.59, and this problem is gone.
