[LLVMdev] some errors with LLVMContext

[Amir Ramezani]

hi all,
i'm building a compiler with LLVM for my engine
i've got this error:
g++.exe -std=c++11 -w -D_LARGEFILE64_SOURCE=1 -DHAVE_W32API_H
-D__WXMSW__ -DwxUSE_UNICODE -DwxUSE_UNICODE_MSLU
-DCRYPTOPP_ENABLE_NAMESPACE_WEAK -DBOOST_THREAD_USE_LIB
-DUNICODE -DSFML_STATIC -DINI_REAL=double -g -c
F:\projects\cpp\AGK\src\compiler.cpp -o obj\Debug\src\compiler.o
In file included from F:\projects\cpp\AGK\src\compiler.cpp:9:0:
F:\projects\cpp\AGK\src\compiler.hpp:54:27: error: 'getGlobalContext'

llvm::IRBuilder<> builder(getGlobalContext());
^
what should i do?
