Workaround with gcc 4.4.x for CUDA 2.3 SDK Options

[highman]

There are several discussions about gcc 4.4.x for CUDA SDK building issues, e.g. on FC 11 I am using.

General solutions are to step back 4.3 or use compat-34. Here is another workaround way:

Please edit common/common.mk

ADD one more flag to NVCCFLAGS
--compiler-options -fno-inline

As in gcc 4.4.x, check against inline function be declared as weak. If you still meet the problem about always-inline functions like memcpy and memset, I suggest to recover common.mk, and override nvccflags -O2 with -O0 or null. This is the cheapest way to go through 4.4.x issue, cheers!


Another suggested again, maybe to Nvidia:
in Makefile, please add two lines for clean
@make -C common -f Makefile_paramgl clean
@make -C common -f Makefile_rendercheckgl clean

Finally,
make clean; make

Done, cheers. :yes:

It doesn't work for me, still reports the same error. I have added the flag, cleaned and make-d.

This is my common.mk

CODE

[highman@gpu common]$ diff common.mk common.mk.org
126c126
<     NVCCFLAGS   += --compiler-options -fno-strict-aliasing --compiler-options -fno-inline
---
>     NVCCFLAGS   += --compiler-options -fno-strict-aliasing

Obviously, it will bring some differences. If no, please check your configuration. post your error informaiton.

And, be careful. un-cleaned library, so suggest to add two more lines in C/Makefile

CODE

clean: tidy $(addsuffix .ph_clean,$(PROJECTS))
        @make -C common clean
        @make -C common -f Makefile_paramgl clean
        @make -C common -f Makefile_rendercheckgl clean

Another way would be to separate the code:
1: minimal cuda code, compiled in a static or shared library with nvcc and gcc 4.3
2: 4.4/4.5 for the rest, link with (1)

This is my common.mk

[highman@gpu common]$ diff common.mk common.mk.org
126c126
< NVCCFLAGS += --compiler-options -fno-strict-aliasing --compiler-options -fno-inline
---
> NVCCFLAGS += --compiler-options -fno-strict-aliasing

I did exactly to your advice, but it still reports the error about weak declaration in simpleTemplates project. The error shows to string.h and string3.h files in /usr/include, and to common_functions.h in cuda subdirs.

Anyway, thanks for your effort.

SOLUTION for Ubuntu 9.10.

Same as for smokyboy, changing to gcc-4.3 in common.mk or adding the no-inline flag did not work. The only way was to uninstall gcc/g++-4.4, and make manually the link of /usr/bin/gcc to /usr/bin/gcc-4.3, and same for g++.

Actually, when you uninstall gcc-4.4 and do the make before creating the link of gcc/g++, the compilation fails at some point because it can't find "gcc" (which makes sense since when you uninstall gcc-4.4, Ubuntu deletes the link /usr/bin/gcc.

But, that would not make any sense since I specified to use CC:=gcc-4.3, then I suspected somewhere else CC and CXX were being re-assigned to gcc/g++.

And the culprit seemed to be

src/simpleAtomicIntrinsics/Makefile2

At end of Makefile2 you can see
NVCC := $(CUDA_INSTALL_PATH)/bin/nvcc
CXX := g++
CC := gcc
LINK := g++ -fPIC

and then all subsequent compilations fail because this

Then, I deleted the CXX, CC and LINK assignments in src/simpleAtomicIntrinsics/Makefile2 and did again make, but the error of "gcc: no such file or directory persisted"

"....
make -C src/simpleTextureDrv/
make[1]: Entering directory `/home/pichards/NVIDIA_GPU_Computing_SDK/C/src/simpleTextureDrv'
gcc: No such file or director
"

Then I simply decided to create manually the link /usr/bin/gcc to gcc-4.3 and theproblem was solved, I could not find exactly the rule in the Makefiles that was trying to use gcc instead of expanding $(CC)...

Then solution for Ubuntu 9.10:

Install gcc and g++ 4.3, then change manually the links gcc and g++ to the 4.3 counterparts.

Not very clean until we figure out where exactly the Makefiles are getting messy
