Hi

Today I found new bug

-o llvmjit_wrap.o llvmjit_wrap.cpp -MMD -MP -MF .deps/llvmjit_wrap.Po
llvmjit.c: In function ‘llvm_resolve_symbols’:
llvmjit.c:1115:57: error: ‘LLVMJITCSymbolMapPair’ undeclared (first use in this function); did you mean ‘LLVMOrcCSymbolMapPair’?
 1115 |         LLVMOrcCSymbolMapPairs symbols = palloc0(sizeof(LLVMJITCSymbolMapPair) * LookupSetSize);
      |                                                         ^~~~~~~~~~~~~~~~~~~~~
      |                                                         LLVMOrcCSymbolMapPair
llvmjit.c:1115:57: note: each undeclared identifier is reported only once for each function it appears in
llvmjit.c: In function ‘llvm_create_jit_instance’:
llvmjit.c:1233:19: error: too few arguments to function ‘LLVMOrcCreateCustomCAPIDefinitionGenerator’
 1233 |         ref_gen = LLVMOrcCreateCustomCAPIDefinitionGenerator(llvm_resolve_symbols, NULL);

I have fedora 37

Hi Pavel,

Some changes are needed for LLVM 15.  I'm working on a patch, but it's
not quite ready yet.  Use LLVM 14 for now.  There are a few
superficial changes like that that are very easy to fix (that struct's
name changed), but the real problem is that in LLVM 15 you have to do
extra work to track the type of pointers and pass them into API calls
that we have a lot of.  https://llvm.org/docs/OpaquePointers.html
