If Dumbledore is the most powerful wizard (allegedly), why would he work at a glorified boarding school? Thanks for the pointer to the patch. Word for someone who keeps a group in good shape? FreeRTOS defines vPortSVCHandler, which is the ISR I want to have handle the SVC interrupt. http://stackoverflow.com/questions/7649979/gcc-alias-to-function-outside-of-translation-unit-aka-is-this-even-the-right-t

Thank you very much.

(glibc has the same problem and uses this same solution). (0000440) jocke But code maintainance is more important, I will not pollute all the C file with custom macros to work around compilers or format lack of optimization.

On Solaris, the native assembler would have caught this error, but GNU as does not. The source tree does contain a tool called indr which is capable of generating these indirections in a limited capacity, but it is not distributed with OS X and anyway not share|improve this answer answered Apr 8 '13 at 15:08 goertzenator 1,0651016 add a comment| up vote 1 down vote I think the problem with alias is, that it expects a declared Follow-Ups: Re: '_ctype_' aliased to undefined symbol '_ctype_b+127' From: Jeff Johnston Index Nav: [DateIndex] [SubjectIndex] [AuthorIndex] [ThreadIndex] Message Nav: [DatePrev][DateNext] [ThreadPrev][ThreadNext] :: (Bloggable a) => a -> IO () Menu Skip

Unusually Linux is the platform that lags behind the others in linker features! Bah. Ultimately I was able to successfully finish the build by commenting out a large chunk of src/msw/ole/activex.cpp. It uses the syscall code from the kernel.

Linux Turning to page 1-16 of the ELF specification we find the definition of the ELF symbol table. In Harry Potter book 7, why didn't the Order flee Britain after Harry turned seventeen? Anyway, one of the Code:.Blocks plugin developer has kindly provided a GCC 4.1.0 binary snapshot, which can be used with an updated MinGW. Though I can compile it with GCC-3.4.5 without any problem, but I'm facing this problem with GCC-4.1.0 which I compiled from source.

This way it compiles properly with gcc-4. Long story short: this is supported by the object file format on OS X and Windows, but you can't get to it from the assembly code level.

When that symbol is linked, both this and the other symbol have the same defined type and value".

I figured I would just add dummy functions in activex.cpp, but I can't even find prototypes for them.

Can you complete this patch? The caller can't do anything with the information that foo is a weak alias; it still needs to generate a PLT entry and the loader will need to perform a relocation. Is it illegal for regular US citizens to possess or read documents leaked by Wikileaks? I analized which one was the problem, but I don't know enough assembly to solve it in a better way.

This seems to be a known GCC bug (listed in Bugzilla as #27636 or #27067). We can think about this patch after the previous one because I think that it is somehow related.
