[LLVMdev] Compile dll on Mingw

[yuan zheng]

Hi,  NAKAMURA Takumi

Thank you, and thanks for your answer.

1.First of all, I test it on Linux . As you said, I have attempted to do,
 "/path/to/configure --enable-shared=yes" on ubuntu9.10.
After compiling, it generates lots of static libraries(.a) and only three
shared library(.so) , libLTO.so,  LLVMHello.so,  profile_rt.so. Is there
anyone which is the "BIG" one as you said?

2.And I find it seems that the option of "--enable-shared=yes" is defult
option. Command: $ ./configure --help ,  it will display this message:
--------------------------------------------------------------------------------------------------
Optional Features:
....
--enable-shared[=PKGS]  build shared libraries
                                      [default=yes]
....
--------------------------------------------------------------------------------------------------
I don't know if I consider is right?

3.By the way, my work environment:
OS : Ubuntu9.10
VirtualBox virtual machion
Virtual OS:  Windows XP
Compile environment:   MinGW and MSYS.
Our need is that: Compile a dynamic module with LLVM on MinGW,
                         So, we need dynamic library of LLVM, that is ".dll"
files.
If you compile LLVM on MinGW ever before? If there is some process
about it ?  Thanks.

4.On MinGW, we configure with "--enable-shared=yes" and compile,
but there is no ".dll" file generate. These are some advice on other
websites.
For instance,  using the tool of "cmake", when configure, add the macro
-DBUILD_SHARED_LIBS=ON.  With this method, it generates some
".dll.a" files --- libLLVMCore.dll.a  libLLVMSupport.dll.a
libLLVMSystem.dll.a.
Meanwhile, it would also appear lot's of errors.
What library types of "dll.a" file? Static or dynamic?  If this method
feasible？

Sorry for those plenty of questions, expect your answer, thanks.


Thanks,
yuanzheng.
