Due to the way inline works in c in gcc, I got errors building a debug build of libpano13 in fedora.
I know several different ways to fix the problem. But I don't know enough about all the ways libpano13 might be built and/or used to have a safe opinion on which way is best. Despite reading many results of google searches and official gcc descriptions, I still can't understand the general rules for inline in gcc c (which are very different from c++ rules). But I do understand this example of the use of inline and why it is wrong. Some questions: Has anyone else built libpano13 debug in Linux? Did you need to work around the problem described below? If so, how? If not, do you have an idea of why it worked for you and not for me? Are the functions float2rgbe and rgbe2float supposed to be exposed to clients of libpano13? Or are they purely internal? Currently in Linux (at least the Fedora package and my own builds in Fedora) they are not exposed. But I don't know if they were meant to be. In fact they are not even exposed to the rest of libpano13 outside of rgbe.c, despite being declared in rgbe.h as if they were meant to be exposed. As currently declared/defined they are never instantiated as individual functions. They might be inlined wherever used within rgbe.c or they might be undefined. That is entirely a free choice of the optimizer, except at lowest optimization level, where they are necessarily undefined. My current work around: I added __attribute__((always_inline)) to the end of line 41 of pt_stdint.h (which is already inside a conditional excluding MSC). That further entrenches the current behavior that c functions using the INLINE macro are not ever usable outside translation units that define them, while it fixes the undefines for unoptimized builds. It forces functions defined that way to be inlined even in the debug build. -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
