<0> hi, I'm having this compiler error, can you give me a hint? I think it's some package thing :/
<0> http://rafb.net/p/8plWGn43.html
<1> is there any guides to cross compilation
<1> im talking linux elf ? <-> win32 pe ?
<1> not differnt archs
<2> hi, http://pastebin.ca/335231
<2> i can't get to properly link my app
<2> i have the symbols defined in libvmkuser.so (which i specify with -lvmkuser), but it doesnt seem to find it
<2> anyone know what else I can try?
<3> you seem to be showing explicit paths all through. strange.
<2> what do you mean?
<3> the only other thing that comes to mind could be...
<2> oh like why i'm linking to /myroot?
<2> i'm crosscompiling
<3> the order in which you perform the linking perhaps. but I'm not certain
<2> i thought so too.. i tried moving -lvmkuser around
<3> anyone awake to help T` out ?
<2> i dont think anyone hangs out here
<2> atleast never really heard anyone speak here.. heh
<3> used to be...
<3> things change.
<3> good luck.
<2> do you know why it complains in libSTAF.so?
<2> could it be something to do with how libSTAF.so is made?
<3> undefined reference to `VmkuserIcon(int*)'
<3> coeff vs. elf, or what?
<3> coff
<2> i think its elf.. i dont know
<2> lemme see
<3> I've run into that issue a few times :)
<3> /myroot/sources/staf-3.20/rel/mvis/staf/retail/lib/libSTAF.so: undefined reference to `VmkuserPerf(char const*, char* const*, char* const*, int, int*, unsigned, int, int*)'
<3> are you certain those routines are exported (or whatever)
<2> ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), not stripped
<2> sec..
<3> http://gcc.gnu.org/onlinedocs/gcc/Link-Options.html
<2> nm libvmkuser.so.0.0
<2> 00001224 T VmkuserPerf
<2> i see that..
<2> so its there in libvmkuser.so
<3> what does that have to do with "libSTAF.so" ?
<2> and if i change the -lvmkuser to like -lblahvmkuser it complains about not able to find that lib
<3> where the error comes from
<2> oh.. i thought libSTAF.so will get the symbol from libvmkuser.so?
<2> i mean.. in libSTAF.so, it is like:
<3> evidently not
<2> <addr> U VmkuserPerf
<2> so you think its the way libSTAF.so was built?
<3> that might be a link to something _else_ that file loads!
<2> because the error we see now, is when its linking the final binary STAF
<3> Why not attempt to include 'libvmkuser.so.0.0' or whatever has the actual routines, and see what happens?
<3> if you haven't tried it yet perhaps?
<2> you mean in the cmdline right? along with STAF.o ?
<3> although, I'm just brainstorming with you now
<3> yeah, I guess. try to help it find these symbols from what contains them
<2> hehe well thats better than nothing :)
<2> yea i did that.. and (re-did it just now).. exact same error
<3> what is this project exactly?
<3> any where you can go to find source similar to what you're doing, and study it
<2> its STAF framework.. http://staf.sourceforge.net/index.php
<2> its used for testing.. QA
<3> I see faq, documentation, and this problem isn't listed
<3> ?
<2> but i'm trying to make it use some of my shared library's calls
<2> nop.. this is a custom change by me.. so unlikely that they will list it
<3> just a sec
<2> heh
<3> it creates a static or shared object when done?
<3> if you're linking from .so, would you not be creating .so ?
<3> .so might have an ***ociated .a
<3> all that was in http://www.network-theory.co.uk/docs/gccintro/gccintro_25.html
<2> the library i'm linking to libvmkuser.so only has .so.. no .a
<3> I still think your answer is still in that tutorial, somewhere
<3> are you creating a Static or Shared file when done?
<2> yea, but the intro is very limited.. i already tried including the files on the cmdline in various places
<3> are you creating a Static or Shared file when done?
<3> or don't you know
<2> shared file
<2> STAF is a executable which uses many shared libs
<3> gcc -Wl,--export-dynamic -Wall -O1 -shared -fPIC
<2> glibc, libSTAF.so, etc..
<3> how many of those options I just listed are you using
<2> -shared i'm not for STAF because thats wrong ofcourse.. -fPIC wont apply for non-shared libs
<2> same for export-dynamic
<2> lemme see if thats used for libSTAF.so
<2> btw.. do you know if there is any prob with c++ apps linking with .so ?
<2> it should work seemlessly right?
<3> oh dear me
<3> A C-app and a C++ needs some consideration, yes
<4> I've run into a bit of a mystery.
<4> Compiling ffmpeg on fbsd on an amd64 machine. -O causes an internal compiler error.
<4> Checking the man page for gcc it says -O1 enables "-fdefer-pop -fmerge-constants -fthread-jumps -floop-optimize -fif-conversion -fif-conversion2 -fdelayed-branch -fguess-branch-probability -fcprop-registers -fomit-frame-pointer"
<4> If I do the compile with all of those options instead of -O1 it compiles fine.
<2> RadSurfer, like?
<2> UberDuper, its possible there is some compatibility issue with amd64 optimization
<2> reduce the optimization
<4> So I'm ***uming there additional optimizations being enabled that the man page isn't listing.
<3> I think I've exhausted my knowledge on the subj T`, but good luck.
<4> So is there any difinitive way to find out what -O1 is actually doing?
<4> It makes no sense that -O1 doesn't work but -fdefer-pop -fmerge-constants -fthread-jumps -floop-optimize -fif-conversion -fif-conversion2 -fdelayed-branch -fguess-branch-probability -fcprop-registers -fomit-frame-pointer
<4> does
<2> UberDuper, hmm
<2> UberDuper, it might be be a bug in the manual
<2> RadSurfer, sorta know why this is happening, but no solution yet
<2> UberDuper, do you know how .so files's symbols have <symbol>@@GLIBC2.2.4 etc..?
<4> Nope.
<4> I'ma noob.
<2> heh ok..
<2> xushi_, hi.. do youj know anything about linking with shared libs?
