mercury-init-test

mercury-init-test: init mercury using the requested plugin and print out our self-address in text format.

usage: mercury-init-test [flags] spec

where spec is 'bmi+tcp' etc.

flags:
 -a      - enable auto_sm mode
 -d log  - run as daemon and print output to given log file
 -n      - init with na listen=false (def=true)
 -s      - IP subnet spec (def=NULL)

To compile: build Mercury first. Then either use cmake (with either CMAKE_INSTALL_PREFIX or CMAKE_PREFIX_PATH pointed at the installed location of Mercury) or compile manually.

Example with cmake and Mercury installed in /tmp/mt:

h0:src/mercury-init-test % ls
CMakeLists.txt	README.md  mercury-init-test.c
h0:src/mercury-init-test % mkdir build
h0:src/mercury-init-test % cd build
h0:mercury-init-test/build % cmake -DCMAKE_PREFIX_PATH=/tmp/mt ..

Example manual build on Linux with Mercury installed in /tmp/mt (adjust compile flags as needed):

h0:src/mercury-init-test % ls
CMakeLists.txt	README.md  mercury-init-test.c
h0:src/mercury-init-test % cc -I/tmp/mt/include \
    -L/tmp/mt/lib -Wl,-rpath=/tmp/mt/lib \
    -O -o mercury-init-test mercury-init-test.c -lmercury -pthread
h0:src/mercury-init-test % ./mercury-init-test 
usage: ./mercury-init-test [flags] spec
where spec is 'bmi+tcp' etc.

flags:
	-a     - enable auto_sm mode
	-d log - run in daemon mode, output to log file
	-n     - init with na listen=false (def=true)
	-s s   - IP subnet spec (def=NULL)
