[Cbc] unable to build - svn externals broken, coinbrew broken ?

Wed Jan 22 11:03:29 EST 2020

I guess this is because the capability to build all projects without
installing depends on being able to find the .pc files for the uninstalled
packages. The configure script used to take care of building the pkg-config
search path so that the uninstalled packages could be found, but we now
finished a complete re-implementation and simplification of the build
harness (which is the reason for the changes you observed) and it no longer
builds that search path automatically.

A relatively easy fix would be to build the search path within coinbrew
itself, since coinbrew knows where the uninstalled packages are. The only
problem is that I noticed cbc-uninstalled.pc is no longer produced. Without
that, I guess there is no way to support building all packages before
installing anything. I personally think this is something we should
support. Stefan, what is your thinking?

Other alternatives if you want to test everything before installing are not
as nice, but workable.

   - If you don't specify a prefix, everything will get built and installed
   into a local directory dist/. Once everything looks good, you can build and
   install where you really want things to be.
   - You can also configure with --enable-relocatable, in which case the
   entire package should be relocatable and you can just move the contents of
   the dist/ directory to the final location.

 By the way, if you want to skip building of any project, you can just say,
e.g., --skip ThirdParty/Mumps or comment the line in the Dependencies file
if you want to avoid adding the argument every time.
