a small patch to cross.mak: a cross-compiled echogs cannot be executed
Created attachment 8969 [details] a few architecture-specific definitions. these covers most existing architectures gs is being built for the two last patches were downloaded from http://repository.timesys.com/buildsources/g/ghostscript/ghostscript-9.05/ and work fine for cross-compiling on my mac (see macports ticket https://trac.macports.org/ticket/34962 ). There are similar patches available on various places (e.g. http://git.yoctoproject.org/cgit.cgi/poky-contrib/tree/meta/recipes-extended/ghostscript ). A few problems with these patches: The reason for writing the explicit endian check is because AC_C_BIGENDIAN() has proven buggy and unreliable. Unless those problems have been addressed, I would prefer the idea of adding an endian configure option to override the explicit test. "cross.mak" is not a file of ours. The solution we have is that you can specify a different AUX_CC used to build the utilities (genconf, genarch, echogs and mkromfs). AUX_CC should be the natve host compiler, rather than the cross compiler. As of a couple of releases ago, genarch can now pull the architecture definition from the "arch" directory, rather than generating it itself - this was specifically added for cross-compiling. So it seems to me that, other than the endian check, the other changes are catered for already, though in slightly different ways. I'll do some digging about the AC_C_BIGENDIAN() problems. No response, closing. |
