C Linker error with stable release under linux - Unsolved

[dirkson]

Hey all. Trying to do this with 2.33 under 32 bit linux:
clang -std=c99 -I src/ -O3 -I lin/newton-dynamics-2.33/packages/linux32/ -L lin/newton-dynamics-2.33/packages/linux32 -lm -lGLU -lGL -lGLEW -lSDL -lalut -lNewton src/ScrumbleClient.c lin/obj/components.o lin/obj/materials.o lin/obj/audio.o -o lin/bin/scrumbleship

Results in this:

lin/newton-dynamics-2.33/packages/linux32/libNewton.so: undefined reference to `dgMallocStack(unsigned int)'
lin/newton-dynamics-2.33/packages/linux32/libNewton.so: undefined reference to `dgFreeStack(void*)'
collect2: ld returned 1 exit status
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [lin/bin/scrumbleship] Error 1

gcc returns similar errors.

Any ideas what's up?

After setting up and testing a windows build, the 2.33 windows dll does not have this problem.

If need be, I can see if the 64 bit linux .so has this issue.

[dirkson]

Attempting to compile with a 64 bit linux 2.33 newton results in:

lin/newton-dynamics-2.33/packages/linux64/libNewton.so: undefined reference to `dgCRC(void const*, int, unsigned int)'
lin/newton-dynamics-2.33/packages/linux64/libNewton.so: undefined reference to `dgRef::m_rtti'
lin/newton-dynamics-2.33/packages/linux64/libNewton.so: undefined reference to `dgFree(void*)'
lin/newton-dynamics-2.33/packages/linux64/libNewton.so: undefined reference to `dgCRC(char const*)'
collect2: ld returned 1 exit status

I hope Julio can look into your problem, he knows best how to build and link newton on linux.

[Julio Jerez]

I will try builling in my 32 bit laptop whin had Linux, see if it show the problem.
there should boy be any difference between the 32 and 64 bit build, in fact thy are a copy an dpset version of each other.

I am trying to avoid to have a dual boot of Linux and window in my machine.
It has being more than one occation than I have to go and figure put how to restart my window each time something goes wrong.

[Julio Jerez]

in my current version that is in SVN in just when to folder
C:\Users\Julio\Desktop\newton-dynamics\coreLibrary_200\projets\linux32\

and I run the make file, and I di dnoi get any link error. I had some harmless warning, but I fix then too.

can you sync to SVN and try that, see if it work?

[JernejL]

Dirkson's problem comes when he tries to build a linux game that uses the newton.so, he gets unresolved dynamic library references there - i think it is as if newton.so tries to import those functions from another external library..

Code: Select all

lin/newton-dynamics-2.33/packages/linux32/libNewton.so: undefined reference to `dgMallocStack(unsigned int)'
lin/newton-dynamics-2.33/packages/linux32/libNewton.so: undefined reference to `dgFreeStack(void*)'


[Julio Jerez]

I though that a .so file is like a dll,
I will try to mak ethe demo and see what happen then.

[Julio Jerez]

Ok JernejL I just build the newtonDemos project in linux, and I fix all the error.

ther were error because of teh newer demos, but other than that I do no see any link error,

basically I jst open the console, go to forder C:\Users\Julio\Desktop\newton-dynamics\applications\newtonDemos\projects\linux32\makefile

type:
make clean
make

and is buidl all o fteh librarys and the elf.

I chekd everything into SVN.
