I am cross-compiling 0MQ and czmq (using gcc 4.8.0) for an embedded Linux target. To keep the install size down, I install only the libraries in the root filesystem ($(ROOT_DIR) variable). Headers, man pages, etc. go elsewhere ($(TOOL_DIR) variable).
I configure 0MQ as follows (I'm omitting environment variables (CC, CPP, PATH, etc.) that I set), which works as expected: ./configure \ --prefix=$(ROOT_DIR) \ --includedir=$(TOOL_DIR)/include \ --datarootdir=$(TOOL_DIR) But czmq only has a configure option for --with-libzmq, and the configure script expects to find both the headers and libraries in that directory. I have patched configure.ac to support separate include and lib dirs (but if you specify --with-libzmq, it'll still work as before). Then I can run configure as follows, and it sets the CFLAGS and LDFLAGS to the correct locations. ./configure \ --prefix=$(ROOT_DIR) \ --includedir=$(TOOL_DIR)/include \ --datarootdir=$(TOOL_DIR) \ --with-libzmq-include-dir=$(TOOL_DIR) \ --with-libzmq-lib-dir=$(ROOT_DIR) My patch is attached. Please let me know if I should submit a bug about this issue, or if I'm doing something wrong. Please also let me know if the patch has any issues. Note that I removed the error if zmq.h was not found, relying on the code to error out later when trying to compile with zeromq. There's probably a more standard way of doing this. Thanks, Patrick
