My understanding is that the build process uses the configure/RELEASE files to dynamically build the dependencies so they are not hard-coded into the Makefile.

I did not have the problem you describe when using assemble_synApps.sh recently.

Hi Mark,
   The assemble_synApps script itself calls "make release" as its final command. So the make knows where to look, but there's nothing there to find because that module hasn't yet been built. For example, areaDetector depends on busy and calc, but the makefile tries to build them in alphabetical order. The script needs to know about dependencies, or at least take them into account when it creates the makefile.

Hi Pete,

You should not need to edit the Makefile.

After you ran assemble_synApps.sh and edited support/configure/RELEASE did you run this command:

make release

You need to do that before then running

make

Subject: building synApps from Git

I just downloaded the latest synApps collection according to the instructions on its site, using the command:
bash ./assemble_synApps.sh

followed, after setting some variables, "make".

It seems that the build works through the modules in alphabetical order, without regard to dependencies. In particular, it tries to build areaDetector very early, which fails because a bunch of libraries from other modules don't exist yet. I edited the Makefile to move the areaDetector reference later in the list, and everything built OK.

Is this how it's supposed to be? Did I do something wrong?
Pete.
