This would give me the ability to invoke cbc execution from any machine, without installing cbc locally. In setting this up, however, I have been forced to confront my substantial ignorance of linux technology. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>To deploy to Lambda, you build your function, zip up the containing folder, and ship it to amazon. They drop it in /var/task on a vm, and route invocations to it. With the exception of \tmp, the whole vm is unwriteable. Amazon sets the load library path to /var/task/lib, so the cbc libs go there. Problem is that the default make hardcodes library paths (RPATH). I find there is a $hardcode_into_libs switch in the libtool scripts. But I don’t know where to touch it.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Question: Where and how do I most simply compel the configure/make to avoid hardcoding load paths into the generated .so files?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>A less pressing issue: the install is nicely versioned and linked. However, it doesn’t seem that amazon likes the shortcuts (or they didn’t survive the trip through multiple zip unzip cycles). I don’t need this flexibility as the package is always deployed monolithically.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Question: How do I turn off the versioning and just generate plain .so files?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>A tangential question while I have you: I want to set a c++ #define (CLP_OUTPUT_FORMAT).
