Building the fractal api library

[Ankita (Garg) Goel]

Hi,

I am trying to build the sample benchmarks under hgfractal/api. I have setup the Alpha cross-compiler toolchain. There were some minor build issues which I could fix. However, not able to resolve the one below:

# cd hgfractal/api

# make

g++ -c  -O1  -D_MODE_=1 -D_UNI_PROCESSOR_=1 -D_PTHREADS_CMP_=2 -D_SHARED_MEM_CMP_=3 -D_COARSE_OPENMP_=4 -D_SHARED_MEM_ITERTHRD_=5 -D_SHARED_MEM_BLOCKTHRD_=6 -D_SHARED_MEM_BLOCKTASK_=7 -D_SIMD_OPENMP_=8 -D_SIMD_BLOCKTASK_=9 -D_TEMPORAL_MULTIPLEX_STREAM_CMP_=10 -D_SPATIAL_MULTIPLEX_STREAM_CMP_=11 -I.  api_asm.cpp -o objexec/./api_asm.o

g++ -c  -O1  -D_MODE_=1 -D_UNI_PROCESSOR_=1 -D_PTHREADS_CMP_=2 -D_SHARED_MEM_CMP_=3 -D_COARSE_OPENMP_=4 -D_SHARED_MEM_ITERTHRD_=5 -D_SHARED_MEM_BLOCKTHRD_=6 -D_SHARED_MEM_BLOCKTASK_=7 -D_SIMD_OPENMP_=8 -D_SIMD_BLOCKTASK_=9 -D_TEMPORAL_MULTIPLEX_STREAM_CMP_=10 -D_SPATIAL_MULTIPLEX_STREAM_CMP_=11 -I.  api.cpp -o objexec/./api.o

make: *** [objexec/./api_frcontext_emul.o] Error 1

Has anyone come across this error ? Also, this is what one needs to do to build the benchmarks right ?

Thanks for your help!

I was referring to this link earlier, http://www.cs.virginia.edu/~jm6dg/fractal/smp.htm, but now it is not accessible (forbidden access).

Jiayuan, could you pl help ?

Hi Ankita,

Are you still not able to access http://www.cs.virginia.edu/~jm6dg/fractal/smp.htm? I just tried and it is accessible, and I didn't modify any permission settings. 

Are you trying to compile the SIMD code to be simulated on MV5? You can type:

make MODE=9

"make" is by default building the benchmarks on the native machine, usually for testing a new benchmark. I haven't come across your error when trying "make", it seems to be caused by some GCC incompatibility with the STL library. I'm using GCC 4.2.4.

Hi Jiayuan,

I am able to access the link now. I am trying to compile the benchmarks uder the api/ directory. For this, I ran make. Even with make MODE=9, I am getting the same error. My GCC version is 4.3.4 though.

I was looking through the source of api, to find the definition of 'find' method that matches the errorneous usage,and I did not find any, hence the error:

api_frcontext_emul.cpp: In member function ‘void frContext::break_loop(ulong)’:

api_frcontext_emul.cpp:346:67: error: no matching function for call to ‘find(std::deque<long unsigned int>::iterator, std::deque<long unsigned int>::iterator, std::map<long unsigned int, long unsigned int, std::less<long unsigned int>, std::allocator<std::pair<const long unsigned int, long unsigned int> > >::mapped_type&)’

make: *** [objexec/./api_frcontext_emul.o] Error 1

Is there a latest version of fractal api ?

"find" is defined in <algorithm>. 

Possible solutions:

1. include <algorithm> explicitly in api_frcontext_emul.cpp, and then replace "find" with "std::find"

2. try explicit type conversion, so instead of  

find(condloops.begin(), condloops.end(), _strmNextLoop[flowid]);

use

find(condloops.begin(), condloops.end(), ulong(_strmNextLoop[flowid]));

Thanks a lot Jiayuan! I could successfully build the fractal library and also the benchmarks. As you suggested, I included <algorithm> explicitly. Then I got some other minor build issues (might be specific to the glibc version of my cross-compiler).
