[Scilab-Dev] Problem using double API

[Vincent Lejeune]

It doesn't work either...

Just in case, the builder_gateway_c.sce script is the following (taken from 
the skeleton toolbox) :
if MSDOS then
  // to manage long pathname
  includes_src_c = '-I""' + get_absolute_file_path('builder_gateway_c.sce') 
+ '../../include/""';
else
  includes_src_c = '-I' + get_absolute_file_path('builder_gateway_c.sce') + 
'../../include/';
end

// PutLhsVar managed by user in sci_sum and in sci_sub
// if you do not this variable, PutLhsVar is added
// in gateway generated (default mode in scilab 4.x and 5.x)
WITHOUT_AUTO_PUTLHSVAR = %t;

tbx_build_gateway('ocl',..
	['ocltest','oclexec';..
	'gInit','gInit'],..
	['sci_simd.c'], ..
	get_absolute_file_path('builder_gateway_c.sce'), ..
	['../../simd'],'',includes_src_c);

clear WITHOUT_AUTO_PUTLHSVAR;

clear tbx_build_gateway;
