but that's really a packaging problem. it is perfectly possible to implement stub functions that encapsulate the opencl stuff and all conditional code, so most of the code can be kept clean of preprocessor magic. see http://darktable.git.sourceforge.net/git/gitweb.cgi?p=darktable/darktable;a=blob;f=src/common/opencl.h;h=5c22dd2ae84251129bd6f14676176ae757acd7d5;hb=HEAD maybe it would even be possible to dlopen() the cl dependencies during runtime? cheers, jo _______________________________________________ Gegl-developer mailing list [email protected] https://lists.XCF.Berkeley.EDU/mailman/listinfo/gegl-developer
