undefined symbol: __acl__convert_SItoFP_32

Hello,  

 

I compiled a .cl file into .aocx in this way: 

aoc -march=emulator kernel.cl -o kernel.aocx 

The compilation succeeds. 

 

Then I try to create a program from the .aocx file in this way: 

program = clCreateProgramWithBinary(opencl_context, 1, devices, lengths, (const unsigned char **)binaries, status, p_err); 

where binaries is an array containing the content of the .aocx file. 

 

When that statement is executed, an error is thrown:  

Error: /tmp/aocl-18105-kernel1.so: undefined symbol: __acl__convert_SItoFP_32 

 

I guess the error is related with the following code in the .cl file: 

int8 x = ....; 

float8 y = convert_float8(x); 

 

It seems that some library containing the __acl__convert_SItoFP_32 is not linked with the .aocx file. 

 

Any idea?  

 

Thanks, 

Hongbo
