Getting exactly same error

[Fever905]

Same error.. little help??

[JochenWilms]

I am getting the exact same error. could it be because of cuda version 7.5?
When i updated the cuda driver to version 8 the problem was solved.

[demosthenesk]

i think this is the case. i have cuda 7.5 from ubuntu repository.

[demosthenesk]

Alternative is xmr-stak. It works fine with cuda 7.5

[ghost]

Workround. add -D_FORCE_INLINES as shown in the Make file. Ubuntu 16 with repo NV cuda:
sudo apt-get install nvidia-cuda-toolkit

$(NVCC) -g -O2 -I . -Xptxas "-abi=no -v" $(NVCC_GENCODE) --maxrregcount=80 --ptxas-options=-v -D_FORCE_INLINES $(JANSSON_INCLUDES) -o $@ -c $<

[eab]

Confirming this works:

-	$(NVCC) -g -O2 -I . -Xptxas "-abi=no -v" $(NVCC_GENCODE) --maxrregcount=80 --ptxas-options=-v $(JANSSON_INCLUDES) -o $@ -c $<
+	$(NVCC) -g -O2 -I . -Xptxas "-abi=no -v" $(NVCC_GENCODE) --maxrregcount=80 --ptxas-options=-v -D_FORCE_INLINES $(JANSSON_INCLUDES) -o $@ -c $< that adding -

in Makefile

[benmesander]

For CUDA 6.5 on Quadro FX 570 (6.5 is newest supporting this card), I had to do the following: --maxregcount=63 in addition ot the -D_FORCE_INLINES

This is using nvidia-340 driver on Ubuntu 16.04 (nvidia-340 is last driver to support Quadro FX 750)

[TheKrimeStopper]

I need a little additional help. Which makefile do I edit? I edited the makefile.in and when I execute ccminer I get a "stack smashing detected" error and the program terminates.
