gcc error aliased to undefined symbol Venedocia, Ohio

Thanks. I have already compiled older versions with older GCCs several times and have released in-house software using it. Description Serge Belyshev 2005-03-26 23:58:09 UTC ------------------------------------------------------------------------------ extern int foo; extern int bar __attribute__ ((alias ("foo"))); ------------------------------------------------------------------------------ $ gcc foo.i foo.i:2: error: ‘bar’ aliased to undefined symbol ‘foo’ $ this code In this case, I recently came across a situation where it would be useful to be able to generate an object file that contained an alias for a symbol defined elsewhere.

Ultimately I was able to successfully finish the build by commenting out a large chunk of src/msw/ole/activex.cpp. Show that a nonabelian group must have at least five distinct elements more hot questions question feed default about us tour help blog chat data legal privacy policy work here advertising Where are sudo's insults stored?

I analized which one was the problem, but I don't know enough assembly to solve it in a better way.

We can think about this patch after the previous one because I think that it is somehow related. elfgcchack.h:7840: error: 'xmlXPtrWrapLocationSet' aliased to undefined symbol ' xmlXPtrWrapLocationSet__internal_alias' make[2]: *** [SAX.lo] Error 1 make[2]: Leaving directory `/home/kmaraas/cvs/gnome/libxml2' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/kmaraas/cvs/gnome/libxml2' make: *** [all] Error As far as I can see, the GNU assembler can't be persuaded to generate this.

The assembler does have rudimentary support for generating weak externals, but only uses it in the rudimentary capacity of supporting the .weak directive (with ELF-style semantics) on Windows. Linux Turning to page 1-16 of the ELF specification we find the definition of the ELF symbol table. It must be overridden somewhere in order to get your ISR in the interrupt vector table.

Probably this is not important since "alias" is a non-standard extension and people who use it should be prepared for such breakage.

Yes, you are right. Thanks for the pointer to the patch.

This is great stuff, and exactly what we want! uclibc-ppc-uint128.patch: Looks ok to me. A defined weak symbol has a lower link precedence than a strong symbol of the same name, and will not cause the linker to generate an error about duplicate symbol definitions Unusually Linux is the platform that lags behind the others in linker features!

However, there seems to be no way to support it on Linux within the bounds of the ELF specification. I have also send an email to the mailing list, but no solution has been found. gcc -m64 -I/home/sjackman/work/debian/newlib/newlib-1.13.0/_build/i686-pc-linux-gnu/64/newlib/targ-include -I/home/sjackman/work/debian/newlib/newlib-1.13.0/newlib/libc/include -DPACKAGE=\"newlib\" -DVERSION=\"1.13.0\" -I. -I../../../../../../newlib/libc/ctype -O2 -Wall -D_I386MACH_ALLOW_HW_INTERRUPTS -DHAVE_FCNTL -fPIC -D_I386MACH_NEED_SOTYPE_FUNCTION -DMISSING_SYSCALL_NAMES -fno-builtin -O2 -g -O2 -O2 -g -O2 -m64 -c ../../../../../../newlib/libc/ctype/ctype_.c -fPIC -DPIC -o .libs/ctype_.o ../../../../../../newlib/libc/ctype/ctype_.c:91: error: up vote 3 down vote favorite 1 I'm working with FreeRTOS on an STM32 (Cortex-M3), and using the CMSIS library from ST to bootstrap everything.

I hope the semantic/behaviour of the gcc extensions won't change again. 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.
