Question

Working under linux for our developement, I have an Eclipse Makefile C Project and I’m trying to override the make command with this so that a custom script I have will run before make to setup additional variables (easier to keep one script in sync than overriding multiple individual project env variables all the time)

Make command: ./setenv.sh && make

Script contents for testing

#!/bin/sh
echo "setenv.sh"

When running this in Eclipse (build project) I see the script output, but make seems to never get called after the script completes. Perhaps I’m missing something and the script requires a return value of some sort and after running it it returns “false” and the chain doesn’t go on but I couldn’t find anything online in my searches on how to get this working.

Note: This is on Eclipse 3.5 Galileo

Thanks

That is probably because ./setenv.sh && make is a shell command and requires an interpreter to get it executed properly.

I would suggest you to set Make command to:

sh -c './setenv.sh && make'

UPD.

To get make targets to be passed as well, one can use $0 and $@ provided by the shell:

sh -c './setenv.sh && $0 $@' make

From bash manual:

-c string

Read and execute commands from string after processing the options, then exit. Any remaining arguments are assigned to the positional parameters, starting with $0.

That is, after Eclipse will append arguments to this command, it would look like:

sh -c './setenv.sh && $0 $@' make targets...

The shell substitutes $0 with make and $@ with the rest passed arguments (if any), in the example above they are targets.... After all, the actually executed command is:

./setenv.sh && make targets...
