To link explicitly to the DLL, you would do the following: gcc -I<include_path> -o broker.exe broker.c "C:\Program Files\ZeroMQ 3.2.2\bin\libzmq-v110-mt-gd-3_2_2.dll"
No -L required. I don't normally try linking to MSVC compiled DLLs, so although the syntax above is correct, I do not know if it will work. gcc -I<include_path> -L<library_path> broker.c -o broker.exe -lzmq will search for a file named libzmq.a or libzmq.dll.a in library_path. The .lib files that you listed are not usable by MinGW. It's simpler to just compile libzmq with MinGW itself. There's a Makefile for mingw32 at: https://github.com/zeromq/libzmq/tree/master/builds/mingw32 This Makefile does not require MSYS to be installed. Just run "mingw32-make -f Makefile.mingw32" It will create both libzmq.dll and its import library libzmq.dll.a You will then be able to use the following syntax: gcc -L. broker.c -o broker.exe -lzmq (this will link to libzmq.dll.a in the current directory) or gcc broker.c -o broker.exe libzmq.dll On Wed, Mar 13, 2013 at 8:52 PM, Alan Ward <[email protected]> wrote: > Hi,**** > > Thanks for your reply.
