I’m trying to build gnu radio with control port, but cmake won’t find my Ice installation. I have Ice-3.4 installed through apt on Ubuntu 13.10. Digging in to the FindIce.cmake I made the following changes: diff --git a/cmake/Modules/FindICE.cmake b/cmake/Modules/FindICE.cmake index 087ee9b…705c019 100644 — a/cmake/Modules/FindICE.cmake +++ b/cmake/Modules/FindICE.cmake @@ -4,7 +4,7 @@ FIND\_PACKAGE(PkgConfig) PKG\_CHECK\_MODULES(PC\_ICE Ice-3.4 QUIET) -if(NOT ICE\_FOUND) +if(NOT PC\_ICE\_FOUND) # Maybe we don’t have a .pc file for Ice. Check for Config.h. If # that exists, get the version string and parse it for the proper # version. @@ -21,11 +21,11 @@ if(NOT ICE\_FOUND) set(ICE\_FOUND TRUE) endif(ICE\_FOUND) endif(ICE\_CONFIG\_INCLUDE\_DIR) -endif(NOT ICE\_FOUND) +endif(NOT PC\_ICE\_FOUND) -if(NOT ICE\_FOUND) +if(NOT PC\_ICE\_FOUND) message(STATUS " package ‘Ice-3.4’ not found") -endif(NOT ICE\_FOUND) +endif(NOT PC\_ICE\_FOUND) # Recheck if we found the right version of ICE and proceed if true. This at least squelches the ‘package Ice-3.4 not found’ message, which is an improvement. (I test this with cmake -P . I’m still not able to get cmake to configure GNU Radio to build control-port, and this is already extending my cmake-fu. I’ve only managed to get this configured properly through PyBOMBS. Any suggestions on fixing this module to properly detect a distro installed Ice? Nathan ---

Have you made sure that python-zeroc-ice is also installed? Tom ---

Ok, yeah, I think I’ve figured out the problem. They completely changed the ICE package config files and the location of the libraries in 14.04. The package config file doesn’t have any include dirs specified and the library points to an installed Microsoft DLL, which seems… strange to me. Basically, I’m thinking that using the package config for Ice is worthless, so I’m going to strip it out of the FindICE-3.5.cmake file (we’ll be pushing up the minimum required version of ICE to 3.5 with our release of v3.8.0, anyways, so support for 3.4 will go away). The other big issue is that the libraries are installed for multi-arch support, so they are located in /usr/lib/libIceX.so, anymore. And we’re using NO\_DEFAULT\_PATH when looking for libraries. I /think/ we started using that setting to support OS X builds. I have this working now on a VM, but I’m going to have to work on patching FindIce-3.5.cmake a little more to make sure everything’s ok and test it on multiple platforms (yay…). If you’ve followed what I said above, you should be able to quickly fix this locally on your own machine. Basically: - remove the use of package config (comment out PKG\_CHECK\_MODULE) - remove the use of NO\_DEFAULT\_PATH in the FIND\_LIBRARY commands Tom ---

I can confirm that this solved the issue and I’m able to build with Ubuntu’s version of Ice. However, I think this also affects 13.10 (that’s what I’ve been using and I upgraded specifically to get ice-3.5). Thanks Tom. ---

If I replace all of the ICE\_FOUND instances with PC\_ICE\_FOUND then I get a syntax error on line 36: string(REGEX REPLACE “/include” “” ICE\_PATH ${ICE\_CONFIG\_INCLUDE\_DIR}). I Don’t see where ICE\_PATH is being set in the first place. Nathan ---

I’ve pushed a branch to my github repo called cmake\_ice\_libs that addresses the issues for both Ice 3.4 and 3.5. I’ll use it tomorrow to test my various setups in-house, but any other feedback about it’s applicability or problems will be helpful!
