What steps will reproduce the problem?
1. Trying to make the simple_example in ./test

2. I do `make`

3. Get an error

What is the expected output? What do you see instead?
Should make the simple_example

What version of the product are you using? On what operating system?
Ubuntu 11.04 32-bit, g++/gcc 4.4.5

Please provide any additional information below.
eamorr@dx2000:~/Desktop/PFAC-v1.1/test$ make
g++ -m32 -fopenmp -c -O2 -D_REENTRANT -Wall -I/usr/local/cuda/include 
-I/home/eamorr/Desktop/PFAC-v1.1/test/include -o ../obj/simple_example.o 
simple_example.cpp
simple_example.cpp:47: fatal error: PFAC.h: No such file or directory
compilation terminated.
make: *** [../obj/simple_example.o] Error 1

I've done an `export 
PFAC_LIB_ROOT=$PFAC_LIB_ROOT:/home/eamorr/Desktop/PFAC-v1.1`

Any information as to how to resolve this problem is much appreciated.

Thanks in advance,

What steps will reproduce the problem?
Make. (OS:  ubuntu 12.04)

What is the expected output? What do you see instead?
static library libpfac.a is not generated post a make in the lib folder. lib 
folder contains libpfac_sm11.so libpfac_sm12.so libpfac_sm13.so libpfac_sm20.so 
and libpfac.so
The  sample test file simple_example.exe terminates with  assertion failed.

What version of the product are you using? On what operating system?
PFAC 1.0, on RHEL 6

I measured the time it takes for PFAC_matchFromHostReduce and the equivalent 
steps when using PFAC_matchFromDeviceReduce. Both functions take about the same 
time to complete when the size of the input string is 100MB.

Timing for PFAC_matchFromHostReduce: 56 ms

Timing for equivalent steps using PFAC_matchFromDeviceReduce:
cudaMalloc: 0.3 ms
cudaMemcpy(d_input_string, h_input_string, input_size, cudaMemcpyHostToDevice): 
18 ms
PFAC_matchFromDeviceReduce: 26 ms
cudaMemcpy of d_pos and d_match_result back to CPU: 0.3 ms
cudaFree of d_input_string, d_pos and d_match_result: 11 ms
Total: 57 ms
